The Effects Of Land Use Change On Ant Communities In New England, Amelia K.L. Curry, Joseph A. Nelsen, Dale R. Stevens, Kaitlyn A. Mathis

Biology

Urbanisation and agricultural expansion are two of the most prevalent and intense forms of land use change worldwide and can have dramatic consequences on biodiversity and biotic community structure. Ants are extremely widespread, ecologically diverse and small ectotherms that are sensitive to changes from a wide range of environmental factors. Therefore, ants make an ideal study organism to examine the effects of anthropogenic land use change on biotic communities. In this study, we examined differences in ant species richness and community composition between urban parks, farms and forest fragments, and related these differences to environmental factors that vary among each …

The Past, Present, And Future Of Predator–Prey Interactions In A Warming World: Using Species Distribution Modeling To Forecast Ectotherm–Endotherm Niche Overlap, Jessica L. Hill, Matthew Grisnik, Ryan J. Hanscom, Jeet Sukumaran, Timothy E. Higham, Rulon W. Clark

Biology

Climate change has the potential to disrupt species interactions across global ecosystems. Ectotherm–endotherm interactions may be especially prone to this risk due to the possible mismatch between the species in physiological response and performance. However, few studies have examined how changing temperatures might differentially impact species' niches or available suitable habitat when they have very different modes of thermoregulation. An ideal system for studying this interaction is the predator–prey system. In this study, we used ecological niche modeling to characterize the niche overlap and examine biogeography in past and future climate conditions of prairie rattlesnakes (Crotalus viridis) and Ord's kangaroo …

Herptile Gut Microbiomes: A Natural System To Study Multi-Kingdom Interactions Between Filamentous Fungi And Bacteria, Lluvia Vargas-Gastélum, Alexander S. Romer, Marjan Ghotbi, Jason W. Dallas, Reed. N. Alexander, Kylie C. Moe, Kerry L. Mcphail, George F. Neuhaus, Leila Shadmani, Joseph W. Spatafora, Jason E. Stajich, Javier F. Tabima, Donald M. Walker

Biology

Reptiles and amphibians (herptiles) are some of the most endangered and threatened species on the planet and numerous conservation strategies are being implemented with the goal of ensuring species recovery. Little is known, however, about the gut microbiome of wild herptiles and how it relates to the health of these populations. Here, we report results from the gut microbiome characterization of both a broad survey of herptiles, and the correlation between the fungus Basidiobolus, and the bacterial community supported by a deeper, more intensive sampling of Plethodon glutinosus, known as slimy salamanders. We demonstrate that bacterial communities sampled from frogs, …

I Spy: Factors Influencing The Observation Of Oxytetracycline In Calcified Structures Of Fishes Viewed Using Standard Light And Fluorescence Microscopy, Meredith B. Pfennig, Derek P. Crane, Nate G. Smith, Dave L. Buckmeier

Biology

The antibiotic oxytetracycline (OTC) is a fluorochrome marker, and fluorescence microscopy is used to view OTC marks in fishes' calcified structures. However, OTC marks have been observed in calcified structures using standard light microscopy for multiple species. Therefore, we conducted an experiment to investigate potential factors (i.e., season, total length of fish, growth rate, and sex) influencing the observation of OTC in calcified structures (otoliths and fin rays or spines) from channel catfish Ictalurus punctatus, gray redhorse Moxostoma congestum, Guadalupe bass Mircopterus treculii, and redbreast sunfish Lepomis auritus viewed using standard light and fluorescence microscopy. OTC stains were not observed …

The Effect Of Urbanization And Temperature On Thermal Tolerance, Foraging Performance, And Competition In Cavity-Dwelling Ants, Brooke A. Harris, Dale Stevens, Kaitlyn A. Mathis

Biology

Human disturbance including rapid urbanization and increased temperatures can have profound effects on the ecology of local populations. Eusocial insects, such as ants, have adapted to stressors of increasing temperature and urbanization; however, these evolutionary responses are not consistent among populations across geographic space. Here we asked how urbanization and incubation temperature influence critical thermal maximum (CT_max) and various ecologically relevant behaviors in three ant species in urban and rural locations in Worcester, MA, USA. We did this by incubating colonies of three species of cavity dwelling ant (Aphaenogaster picea, Tapinoma sessile, and Temnothorax longispinosus) from 2 habitat …

Sulfur Assimilation Using Gaseous Carbonyl Sulfideby The Soil Fungus Trichoderma Harzianum, Ryuka Iizuka, Shohei Hattori, Yusuke Kosaka, Yoshihito Masaki, Yusuke Kawano, Iwao Ohtsu, David Hibbett, Yoko Katayama, Makoto Yoshida

Biology

Fungi have the capacity to assimilate a diverse range of both inorganic and organic sulfur compounds. It has been recognized that all sulfur sources taken up by fungi are in soluble forms. In this study, we present evidence that fungi can utilize gaseous carbonyl sulfide(COS) for the assimilation of a sulfur compound. We found that the filamentousfungus Trichoderma harzianum strain THIF08, which has constitutively high COS-degrading activity, was able to grow with COS as the sole sulfur source. Cultivation with 34S-labeled COS revealed that sulfur atom from COS was incorporated into intracellular metabolites such as glutathione and ergothioneine. COS degradation …

Fauna Associated With American Alligator (Alligator Mississippiensis) Nests In Coastal South Carolina, Usa, Thomas R. Rainwater, Randeep Singh, Clarissa A. Tuten, Aaron M. Given, Parker W. Gibbons, Bo Song, Steven G. Platt, Philip M. Wilkinson, Catherine M. Bodinof Jachowski

Biology

Crocodilians are considered to be “ecosystem engineers” because their modification of habitats provides opportunities for feeding, drinking, breeding, and other vital life activities to a wide variety of other animals. One such habitat modification is the construction of nest mounds during the breeding season by most crocodilian species, including American alligators (Alligator mississippiensis). While many reports exist describing wildlife associated with alligator nests, no studies have quantified faunal associates and their corresponding behaviors while visiting nests. To address this data gap, we used automated game cameras to monitor wildlife and their behaviors at alligator nests during the egg incubation period …

Loss Of Courtship Suppression Memory In A Drosophila Melanogaster Model Of Alzheimer’S Disease, Eric Robles, Johannes Berlandi, Chris Ellis, Tianyi Wu, Astrid Jeibmann, Fang-Ju Lin

Biology

Alzheimer’s disease (AD) is the most prevalent and lethal neurodegenerative disease. Memory loss and motor dysfunction are accompanied by pathological hallmarks like neurofibrillary tangles or amyloid plaques. In this study, courtship suppression assay was used to assess learning and memory of a transgenic Drosophila melanogaster (the fruit fly) line expressing human Amyloid beta 42 (Aβ42). At young age (4–6 days old), both parental control and AD flies displayed lower courtship indices during training after being rejected by previously mated females. However, in the subsequent testing phase, young AD flies showed compromised recall memory, unlike that of parental controls. Neither control …

Biology

As a small animal that recapitulates many fundamental aspects of human disease, Drosophila lends itself to probing the biological activity of molecules and drug candidates. Here, we present a protocol to build a drug-testing pipeline in Drosophila. We describe steps for generating synchronous populations of Bicaudal C mutants by genetic crossing and wild-type fly culturing for controlled compound administration and exemplary phenotypic assays. For complete details on the use and execution of this protocol, please refer to Millet-Boureima et al.,¹ Millet-Boureima et al.,² and Gamberi et al.³

Phylogenomics Reveals The History Of Host Use In Mosquitoes, John Soghigan, Charles Sither, Silvia Andrade Justi, Gen Morinaga, Brian K. Cassel, Christopher J. Vitek, Todd P. Livdahl, Siyang Xia, Andrea Gloria-Soria, Jeffrey R. Powell, Thomas Zavortink, Christopher M. Hardy, Nathan D. Burkett-Cadena, Lawrence E. Reeves, Richard C. Wilkerson, Robert R. Dunn, David K. Yeates, Maria Anice Sallum, Brian D. Byrd, Michelle D. Trautwein, Yvonne-Marie Linton, Michael H. Reiskind, Brian M. Wiegmann

Biology

Mosquitoes have profoundly affected human history and continue to threaten human health through the transmission of a diverse array of pathogens. The phylogeny of mosquitoes has remained poorly characterized due to difficulty in taxonomic sampling and limited availability of genomic data beyond the most important vector species. Here, we used phylogenomic analysis of 709 single copy ortholog groups from 256 mosquito species to produce a strongly supported phylogeny that resolves the position of the major disease vector species and the major mosquito lineages. Our analyses support an origin of mosquitoes in the early Triassic (217 MYA [highest posterior density region: …

Essential Role Of The Amino-Terminal Region Of Drosha For The Microprocessor Function, Amit Prabhakar, Song Hu, Jin Tang, Prajakta Ghatpande, Giorgio Lagna, Xuan Jiang, Akiko Hata

Biology

Drosha is a core component of the Microprocessor complex that cleaves primary-microRNAs (pri-miRNAs) to generate precursor-miRNA and regulates the expression of ∼80 ribosomal protein (RP) genes. Despite the fact that mutations in the amino-terminal region of Drosha (Drosha-NTR) are associated with a vascular disorder, hereditary hemorrhagic telangiectasia, the precise function of Drosha-NTR remains unclear. By deleting exon 5 from the Drosha gene and generating a Drosha mutant lacking the NTR (ΔN), we demonstrate that ΔN is unable to process pri-miRNAs, which leads to a global miRNA depletion, except for the miR-183/96/182 cluster. We find that Argonaute 2 facilitates the processing …

Unraveling The Functional Dark Matter Through Global Metagenomics, Georgios A. Pavlopoulos, Fotis A. Baltoumas, Sirui Liu, Oguz Selvitopi, Antonio Pedro Camargo, Stephen Nayfach, Ariful Azad, Simon Roux, Lee Call, Natalia N. Ivanova, Min I. Chen, David Paez-Espino, Evangelos Karatzas, Nathan Ahlgren

Biology

Metagenomes encode an enormous diversity of proteins, reflecting a multiplicity of functions and activities^1,2. Exploration of this vast sequence space has been limited to a comparative analysis against reference microbial genomes and protein families derived from those genomes. Here, to examine the scale of yet untapped functional diversity beyond what is currently possible through the lens of reference genomes, we develop a computational approach to generate reference-free protein families from the sequence space in metagenomes. We analyse 26,931 metagenomes and identify 1.17 billion protein sequences longer than 35 amino acids with no similarity to any sequences from 102,491 …

Loggerhead Shrike Occurrence Along Urban Gradients In South Carolina’S Coastal Plain, Michelle A. Krauser, Christopher E. Hill

Biology

The urban landscape is understudied compared to less developed ecosystems, despite providing suitable habitat for wildlife, including some species of grassland birds. Loggerhead Shrikes (Lanius ludovicianus) are predatory songbirds that frequent grasslands and have been observed using grassy areas in developed and more natural landscapes, yet remain largely unstudied in developed landscapes. We investigated the effects of development, measured as impervious surface percentage, on Loggerhead Shrike occurrence in urban areas in South Carolina, U.S.A, and also tracked canopy cover (%), highway density (m/ha), non-highway road density (m/ha), total road density (m/ha), and powerline density (m/ha). The first author searched 300 …

Transcriptomics Of Temporal- Versus Substrate-Specific Wood Decay In The Brown-Rot Fungus Fibroporia Radiculosa, Byoungnam Min, Steven Ahrendt, Anna Lipzen, Cristina E. Toapanta, Robert A. Blanchette, Dan Cullen, David Hibbett

Biology

Brown-rot fungi lack many enzymes associated with complete wood degradation, such as lignin-attacking peroxidases, and have developed alternative mechanisms for rapid wood breakdown. To identify the effects of culture conditions and wood substrates on gene expression, we grew Fibroporia radiculosa in submerged cultures containing Wiley milled wood (5 days) and solid wood wafers (30 days), using aspen, pine, and spruce as a substrate.

Characterizing Host-Pathogen Interactions Between Zostera Marina And Labyrinthula Zosterae, Yaamini R. Venkataraman, Amanda Shore, Sukanya Dayal, James Sanghyun Lee, Mahsa Alidoost Salimi, Grace Crandall, Malina M. Loeher, Mark Stoops, Megan Swanger, Morgan E. Eisenlord, Kathryn L. Van Alstyne, Mark D. Fast, Colleen A. Burge, Maya L. Groner

Biology

Introduction: Seagrass meadows serve as an integral component of coastal ecosystems but are declining rapidly due to numerous anthropogenic stressors including climate change. Eelgrass wasting disease, caused by opportunistic Labyrinthula spp., is an increasing concern with rising seawater temperature. To better understand the host-pathogen interaction, we paired whole organism physiological assays with dual transcriptomic analysis of the infected host and parasite.

Methods:: Eelgrass (Zostera marina) shoots were placed in one of two temperature treatments, 11° C or 18° C, acclimated for 10 days, and exposed to a waterborne inoculation containing infectious Labyrinthula zosterae (Lz) or sterile seawater. At two- and …

Investigating The Sequence Landscape In The Drosophila Initiator Core Promoter Element Using An Enhanced Marz Algorithm, Jacqueline Dresch, Regan D. Conrad, Daniel Klonaros, Robert Drewell

Biology

The core promoter elements are important DNA sequences for the regulation of RNA polymerase II transcription in eukaryotic cells. Despite the broad evolutionary conservation of these elements, there is extensive variation in the nucleotide composition of the actual sequences. In this study, we aim to improve our understanding of the complexity of this sequence variation in the TATA box and initiator core promoter elements in Drosophila melanogaster. Using computational approaches, including an enhanced version of our previously developed MARZ algorithm that utilizes gapped nucleotide matrices, several sequence landscape features are uncovered, including an interdependency between the nucleotides in position 2 …

The Dictyostelium Discoideum Genome Lacks Significant Dna Methylation And Uncovers Palindromic Sequences As A Source Of False Positives In Bisulfite Sequencing, Robert Drewell, Tayla C. Cormier, Jacob L. Steenwyk, James St Denis, Javier F. Tabima, Jacqueline Dresch, Denis A. Larochelle

Biology

DNA methylation, the addition of a methyl (CH3) group to a cytosine residue, is an evolutionarily conserved epigenetic mark involved in a number of different biological functions in eukaryotes, including transcriptional regulation, chromatin structural organization, cellular differentiation and development. In the social amoeba Dictyostelium, previous studies have shown the existence of a DNA methyltransferase (DNMA) belonging to the DNMT2 family, but the extent and function of 5-methylcytosine in the genome are unclear. Here, we present the whole genome DNA methylation profile of Dictyostelium discoideum using deep coverage replicate sequencing of bisulfite-converted gDNA extracted from post-starvation cells. We find an overall …

Are Adoptions In A Predatory Songbird A Strategy To Aid Mate Acquisition?, Christopher E. Hill, Kyle R. Miles, Katie A. Maddox, Amy Tegeler

Biology

Adoption of unrelated young by adult birds is costly and therefore they should avoid it unless adoption carries compensating benefits. Loggerhead Shrikes (Lanius ludovicianus) have a monogamous mating system with low rates of extra-pair paternity and biparental care of young. To date, no documented instances of adoption have been published in this species. In two small nesting populations in South Carolina, we documented six cases in three years in which an unpaired Loggerhead Shrike adopted a brood of apparently unrelated nestlings or fledglings, in some cases sharing provisioning duties with the brood’s mother and in two cases taking over care …

Transcriptome Profile In Drosophila Kc And S2 Embryonic Cell Lines, Daniel Klonaros, Jacqueline M. Dresch, Robert A. Drewell

Biology

Drosophila melanogaster cell lines are an important resource for a range of studies spanning genomics, molecular genetics, and cell biology. Amongst these valuable lines are Kc167 (Kc) and Schneider 2 (S2) cells, which were originally isolated in the late 1960s from embryonic sources and have been used extensively to investigate a broad spectrum of biological activities including cell-cell signaling and immune system function. Whole-genome tiling microarray analysis of total RNA from these two cell types was performed as part of the modENCODE project over a decade ago and revealed that they share a number of gene expression features. Here, we …

Coordination Of Hydraulic And Morphological Traits Across Dominant Grasses In Eastern Australia, Robert J. Griffin-Nolan, Jeff Chieppa, Alan K. Knapp

Biology

1. Leaf hydraulic traits characterize plant drought tolerance and responses to climate change. Yet, plant hydraulics are biased towards northern hemisphere woody species. We collected rhizomes of several perennial grass species along a precipitation gradient in eastern Australia and grew them in an experimental pot study to investigate potential trade-offs between drought tolerance and plant morphology.
2. We measured the following leaf hydraulic traits: the leaf water potential (Ψleaf) at 50% and 88% loss of leaf hydraulic conductance (P50Kleaf and P88Kleaf), the Ψleaf at 50% loss of stomatal conductance (P50gs), leaf turgor loss point (TLP), leaf dry matter content (LDMC), leaf modulus …

Smith, John Donoghue, Steven Ahrendt, William Andreopoulos, Guifen He, Kurt Labutti, Anna Lipzen, Vivian Ng, Robert Riley, Laura Sandor, David Hibbett

Biology

Lentinula is a broadly distributed group of fungi that contains the cultivated shiitake mushroom, L. edodes. We sequenced 24 genomes representing eight described species and several unnamed lineages of Lentinula from 15 countries on four continents. Lentinula comprises four major clades that arose in the Oligocene, three in the Americas and one in Asia–Australasia. To expand sampling of shiitake mushrooms, we assembled 60 genomes of L. edodes from China that were previously published as raw Illumina reads and added them to our dataset. Lentinula edodes sensu lato (s. lat.) contains three lineages that may warrant recognition as species, one including …

Diverse Marine T4-Like Cyanophage Communities Are Primarily Comprised Of Low-Abundance Species Including Species With Distinct Seasonal, Persistent, Occasional, Or Sporadic Dynamics, Emily Dart, Jed A. Fuhrman, Nathan A. Ahlgren

Biology

Cyanophages exert important top-down controls on their cyanobacteria hosts; however, concurrent analysis of both phage and host populations is needed to better assess phage-host interaction models. We analyzed picocyanobacteria Prochlorococcus and Synechococcus and T4-like cyanophage communities in Pacific Ocean surface waters using five years of monthly viral and cellular fraction metagenomes. Cyanophage communities contained thousands of mostly low-abundance (<2% relative abundance) species with varying temporal dynamics, categorized as seasonally recurring or non-seasonal and occurring persistently, occasionally, or sporadically (detected in ≥85%, 15-85%, or <15% of samples, respectively). Viromes contained mostly seasonal and persistent phages (~40% each), while cellular fraction metagenomes had mostly sporadic species (~50%), reflecting that these sample sets capture different steps of the infection cycle-virions from prior infections or within currently infected cells, respectively. Two groups of seasonal phages correlated to Synechococcus or Prochlorococcus were abundant in spring/summer or fall/winter, respectively. Cyanophages likely have a strong influence on the host community structure, as their communities explained up to 32% of host community variation. These results support how both seasonally recurrent and apparent stochastic processes, likely determined by host availability and different host-range strategies among phages, are critical to phage-host interactions and dynamics, consistent with both the Kill-the-Winner and the Bank models.

Evolution Of Chemical-Cue-Mediated Antipredator Behavior In Threespine Stickleback Populations Experiencing Northern Pike Predation, Dale R. Stevens, Melissa A. Graham, Christina I. Bardjis, Susan A. Foster, John A. Baker, Kaitlyn A. Mathis

Biology

Human-mediated environmental challenges are severely impacting local and global levels of biodiversity. Phenotypic plasticity can play a major role in aiding population persistence because plasticity can buffer populations from novel challenges. Given this role, it is possible for the degree of plasticity to evolve rapidly as it may place phenotypes near, but not exactly on, an adaptive peak for the new environment. Here, we asked if behavioral plasticity evolves following the introduction of a novel predator. We measured behavioral responses of threespine stickleback (Gasterosteus aculeatus) populations, with and without the introduced apex predator northern pike (Esox lucius), to three different …

Behavioral Diversity And Biomechanical Determinants Of The Outcome Of A Fish Predator–Prey Interaction, Milton Q.G.A., Iii, Philip Bergmann

Biology

Predator–prey interactions are ubiquitous and under strong selection because of the consequences experienced by both predator and prey if they lose the interaction. Biomechanics and behavior play important roles in the outcome of these interactions, but many studies focus on the prey, restrict the range of behaviors considered, and the role of prey boldness in the outcome is not understood. We used high-speed video to test for effects of multiple measures of performance and kinematics of both the predator and prey, and boldness of prey on the outcome of interactions between Pike Cichlids (Crenicichla sp.) and Guppies (Poecilia reticulata). We …

County-Level Societal Predictors Of Covid-19 Cases And Deaths Changed Through Time In The United States: A Longitudinal Ecological Study, Philip J. Bergmann, Nathan A. Ahlgren, Rosalie A. Torres Stone

Biology

People of different racial/ethnic backgrounds, demographics, health, and socioeconomic characteristics have experienced disproportionate rates of infection and death due to COVID-19. This study tests if and how county-level rates of infection and death have changed in relation to societal county characteristics through time as the pandemic progressed. This longitudinal study sampled monthly county-level COVID-19 case and death data per 100,000 residents from April 2020 to March 2022, and studied the relationships of these variables with racial/ethnic, demographic, health, and socioeconomic characteristics for 3125 or 97.0% of U.S. counties, accounting for 96.4% of the U.S. population. The association of all county-level …

Ocean Acidification Does Not Overlook Sex: Review Of Understudied Effects And Implications Of Low Ph On Marine Invertebrate Sexual Reproduction, Jacqueline L. Padilla-Gamiño, Lindsay Alma, Laura H. Spencer, Yaamini R. Venkataraman, Leah Wessler

Biology

Sexual reproduction is a fundamental process essential for species persistence, evolution, and diversity. However, unprecedented oceanographic shifts due to climate change can impact physiological processes, with important implications for sexual reproduction. Identifying bottlenecks and vulnerable stages in reproductive cycles will enable better prediction of the organism, population, community, and global-level consequences of ocean change. This article reviews how ocean acidification impacts sexual reproductive processes in marine invertebrates and highlights current research gaps. We focus on five economically and ecologically important taxonomic groups: cnidarians, crustaceans, echinoderms, molluscs and ascidians. We discuss the spatial and temporal variability of experimental designs, identify trends …
