The genus Phyllophaga Harris is extremely diverse, with over 850 species currently assigned to it, all occurring in the New World. As with almost all Phyllophaga in the West Indies, this new species belongs to the subgenus Cne­marachis Saylor, whose members have the outer surface of the metatibia with an incomplete carina. As discussed by Smith and Paulsen (2015), this subgenus is endemic to the West Indies and has a …

A New Genus Of Predatory Midge In The Monohelea Complex From Eocene Baltic Amber (Diptera: Ceratopogonidae), Ryszard Szadziewski, William L. Grogan Jr., Elżbieta Sontag, Błażej Bojarski

Insecta Mundi

Monogedania, a new fossil monotypic genus of predatory midge (Diptera: Ceratopogonidae) is described from Eocene Baltic amber and its position within the Monohelea complex is discussed. We dis­covered that the membranous portion of the aedeagus is extended in Monogedania clunipes (Loew), new combination, which suggests that the aedeagus of some extinct predatory midges can be penis-like. The Eocene Monohelea baltica Szadziewski, is transferred to the genus Schizohelea Kieffer, new combination, and, the previously unknown female is described, and key characters are included in color photographs of its entire habitus, head, distal hind tarsomeres and claws.

Dichotomius Woodruffi, A New Dichotomius Species Of The Agenor Group From Costa Rica And Nicaragua (Coleoptera: Scarabaeidae: Scarabaeinae), Ángel Solis, Burt Kohlmann

Insecta Mundi

We describe a new species of Dichotomius Hope, 1838, from the D. agenor species-group from Costa Rica and Nicaragua: D. woodruffi Solís and Kohlmann, new species (Coleoptera: Scarabaeidae: Scara­baeinae). Based on this discovery, we confirm that Dichotomius enioi Montoya-Molina and Vaz-de-Mello, 2021 and D. agenor (Harold, 1869) are not currently distributed in Costa Rica. Instead, the only species of Dichotomius that are currently distributed in Costa Rica from the D. agenor species-group are D. centralis (Harold, 1869) and D. woodruffi. We discuss the distribution of the Dichotomius agenor species-group in Central America.

Euscorpius

A new species of the genus Compsobuthus Vachon, 1949 (Buthidae) belonging to the werneri group is described from two localities in Jalgaon District, Maharashtra, India. The new species can be easily distinguished from all four members of the werneri group known from India and Pakistan by combination of nonoverlapping morphological characters. Compsobuthus satpuraensis sp. n. is the first species of this genus to be reported from the state of Maharashtra and fourth to be reported from India.

Addition Of Inexpensive Lights To Aquatic Turtle Traps Improves Trapping Efficiency In Early Spring, Jenna B. Myers, Michael J. Bender, Maggie M. Woodall*, Jennifer L. Mook

Georgia Journal of Science

Aquatic turtles are essential contributors to many freshwater ecosystems, but they face a myriad of threats, necessitating periodic monitoring of population status. Increasing turtle trapping efficiency has the potential to improve conservation efforts, particularly when population sizes are low or sampling conditions are suboptimal. In an effort to improve trapping efficiency, we added LED lights to turtle traps in an attempt to attract kinosternid turtles. Our investigation into the effectiveness of LED lights as an attractant was based on evidence suggesting that these turtles may forage using both visual and olfactory cues. Lights significantly increased captures of kinosternid turtles during …

A New Species Of Brachycerocoris Costa (Hemiptera: Heteroptera: Pentatomidae: Podopinae) From The Philippines, Joseph E. Eger Jr.

Not Only Severe Events: Moderate Dry Periods Impact The Hydraulic Functioning And Survival Of Planted Ponderosa Pine Seedlings, Carolyn R. Koehn, Matthew D. Petrie, Robert M. Hubbard

Life Sciences Faculty Research

Juvenile tree survival will increasingly shape the persistence of ponderosa pine forests in the western United States. In contrast to severe pulse disturbances that induce widespread adult and juvenile tree mortality, moderate periods of low rainfall and warm temperatures may reduce forest persistence by killing juvenile trees at the seedling stage. Intensification of these periods in a changing climate could therefore increasingly restrict both natural regeneration and artificial regeneration of planted seedlings. We conducted a controlled field experiment at a single site in the Front Range of Colorado, USA, to determine the responses and survival of 3 Colorado subpopulations of < 1 year old potted ponderosa pines to moderately dry conditions, variation in small rainfall events based on observed patterns, and shaded and unshaded microsite environments. Near surface soil moisture increased slightly following small rainfall events, but declined over the 45-day experimental period. Seedling transpiration and associated canopy cooling declined after ∼13 days, and further declines in transpiration and canopy cooling suggest that the majority of trees in lower rainfall treatments experienced hydraulic dysfunction between days ∼20–30. After 45 days, mortality across all subpopulations and treatments, inferred by relative water loss, exceeded 90–95%. Despite some uncertainty pertaining to the stress tolerance of nursery grown versus naturally germinated conifers, our results show that planted ponderosa pine seedlings < 1 year old are unlikely to survive moderate dry periods of 20+ days relying on small rainfall events. Although microsite conditions and soil moisture availability shaped tree hydraulic functioning early in the experiment (days 1–13), later functioning was shaped predominately by the legacy of rainfall treatments. Our results illustrate the importance of moderate dry events that occur consistently as part of seasonal variation in climate, and show how their intensification may constitute a sustained press that limits opportunities for natural and artificial regeneration.

A Review Of The Impacts Of Invasive Wild Pigs On Native Vertebrates, Matthew T. Mcdonough, Stephen S. Ditchkoff, Mark D. Smith, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

The wild pig (Sus scrofa) is a successful invasive species that has become well established outside of its native range in Eurasia. The invasive wild pig is the result of released or escaped domesticated livestock becoming feral, or Eurasian boar introduced for hunting purposes. The global spread of wild pigs has recently been exacerbated in some areas, such as the USA, by anthropogenically assisted dispersal. Once established in novel ecosystems, wild pigs have the potential to have significant negative impacts on the ecosystem, and the scientific literature is replete with examples. It is generally accepted that wild pigs …

Use Of A Direct, Rapid Immunohistochemical Test For Diagnosis Of Rabies Virus In Bats, Charles E. Rupprecht, Lolita Van Pelt, April D. Davis, Richard B. Chipman, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies, a zoonotic encephalitis due to transmission of a lyssavirus, such as rabies virus (RABV), has the highest case fatality of any infectious disease. A global program for the elimination of human rabies caused by dogs is proposed for realization by 2030. Sensitive, specific, and inexpensive diagnostic tests are necessary for enhanced surveillance to detect infection, inform public health and veterinary professionals during risk assessments of exposure, and support overall programmatic goals. Multiple laboratory techniques are used to confirm a suspect case of rabies. One method for the detection of lyssavirus antigens within the brain is the direct rapid immunohistochemical …

Faculty Journal Articles

Premise of the study

Evolutionary studies require solid phylogenetic frameworks, but increased volumes of phylogenomic data have revealed incongruent topologies among gene trees in many organisms both between and within genomes. Some of these incongruences indicate polytomies that may remain impossible to resolve. Here we investigate the degree of gene-tree discordance in Solanum, one of the largest flowering plant genera that includes the cultivated potato, tomato, and eggplant, as well as 24 minor crop plants.

Methods

A densely sampled species-level phylogeny of Solanum is built using unpublished and publicly available Sanger sequences comprising 60% of all accepted species (742 spp.) …

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh

Publications and Research

Background

Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging to …

Size Estimates Of The Extinct Marine Snake Pterosphenus Schucherti From Eocene-Aged Sediments Of Central Georgia, Colin J. Calvert, Alfred J. Mead, Dennis Parmley

Georgia Journal of Science

Fossil snakes are most often identified from isolated vertebrae, complicating estimations of total body lengths of extinct taxa. Here we estimate the range of total body length of the late Eocene North American palaeophiid marine snake Pterosphenus schucherti based on 29 recently collected fossil vertebrae from Wilkinson County, Georgia, USA. Previous research suggests that the palaeophiids are most closely related to modern boids. Total body length estimates here are based on family-specific regressions of centrum length versus known total body length in extant members of Boidae, Pythonidae, and Colubridae. The high correlation coefficients for the family specific regressions supports previous …

Mark-Recapture Study And Habitat Assessment For The Northern Metalmark Butterfly, Calephelis Borealis (Lepidoptera: Riodinidae), Weston J. Henry, Kristian S. Omland, Henry Frye, Wagner L. David

EEB Articles

Background: The northern metalmark (Calephelis borealis), is an exceedingly local, globally rare butterfly that is declining across the Midwestern and Northeastern USA. The principal stressors driving colony losses include afforestation and invasive plants that crowd out its larval hostplant (Packera ovata) and nectar resources.

Aims/Methods: To better understand its declines and guide restoration efforts, we 1) performed a mark-recapture study in Connecticut to document population trends where we were actively managing vegetation; 2) conducted a range-wide survey for evidence of phylogeographic structure, using cytochrome oxidase (CO1); 3) investigated abundance determinants of its larval foodplant, Packera ovata …

Journal of Bioresource Management

Watersheds are critical habitats for a diverse array of organisms. Among all the fauna, anurans are excellent biological indicators of environmental health. The community structure is often associated with a relationship between species diversity and diet. An anuran survey was conducted along riparian zones of three selected barangays of Calayagon Watershed (Guinabsan, Rizal, and Malpoc), Philippines. Extensive opportunistic methods for a total of 480 man-hours were spent traversing the area. A total of 195 individuals, consisting of seven species from four families, were recorded. Seventy-two percent of the individual species were regarded as Least concern, and 14 % were Near-threatened. …

Toxical Effect Of Euphorbia Guyoniana Aqueous Extracts (Euphorbiaceae) On Mortality, Larval Development And Sexual Behavior Of Drosophila Melanogaster (Diptera: Drosophilidae), Chabi Lila, Habbachi Wafa, Tahraoui Abdelkrim

Journal of Bioresource Management

Euphorbia guyoniana (Boiss and Reut) is a plant of Euphorbiaceae family common throughout the northern Sahara and pre-desert regions. In traditional medicine, they are used in the treatment of various infections. Euphorbiaceae contain various chemical compounds families such as alkaloids, which give them a toxic effect. The toxic effects of seeds decoctions on mortality and development of 3rd instar larvae of Drosophila melanogaster are studied. A treatment by ingestion shows a good larvicidal activity of this extract. It was shown that the chemical compounds contained in the extract, act on the fly development cycle as most of pupae do not …

Temperature-Induced Multi-Species Cohort Effects In Sympatric Snakes, Richard B. King

Faculty Articles, Papers, and Other Scholarship

In reptiles, reproductive maturity is often determined by size rather than age. Consequently, growth early in life may influence population dynamics through effects on generation time and survival to reproduction. Because reproductive phenology and pre- and post-natal growth are temperature dependent, environmental conditions may induce multi-species cohort effects on body size in sympatric reptiles. I present evidence of this using 10 years of neonatal size data for three sympatric viviparous snakes, Dekay's Brown snakes (Storeria dekayi), Red-bellied Snakes (S. occipitomaculata), and Common Garter snakes (Thamnophis sirtalis). End-of-season neonatal size varied in parallel across species such that snout–vent length was 36%–61% …

Adultery and Fidelity in the Lais of Marie de France

Using both literary and historical analysis, I will examine contrasting depictions of adultery and fidelity within the lais written by 12th-century poet Marie de France. A lai is a type of narrative poem, ranging in length from 118 to 1184 lines. Many of Marie de France’s lais follow the literary trope known as courtly love; however, the reader is encouraged to sympathize with different characters depending on the lai. In some lais, the reader …

Optimizing Management Of Invasions In An Uncertain World Using Dynamic Spatial Models, Kim M. Pepin, Amy J. Davis, Rebecca S. Epanchin-Niell, Andrew M. Gormley, Joslin L. Moore, Timothy J. Smyser, H. Bradley Shaffer, William L. Kendall, Katriona Shea, Michael C. Runge, Sophie Mckee

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal drives invasion dynamics of nonnative species and pathogens. Applying knowledge of dispersal to optimize the management of invasions can mean the difference between a failed and a successful control program and dramatically improve the return on investment of control efforts. A common approach to identifying optimal management solutions for invasions is to optimize dynamic spatial models that incorporate dispersal. Optimizing these spatial models can be very challenging because the interaction of time, space, and uncertainty rapidly amplifies the number of dimensions being considered. Addressing such problems requires advances in and the integration of techniques from multiple fields, including ecology, …

An Efficient Method Of Evaluating Multiple Concurrent Management Actions On Invasive Populations, Amy J. Davis, Randy Farrar, Brad Jump, Parker Hall, Travis Guerrant, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Evaluating the efficacy of management actions to control invasive species is crucial for maintaining funding and to provide feedback for the continual improvement of management efforts. However, it is often difficult to assess the efficacy of control methods due to limited resources for monitoring. Managers may view effort on monitoring as effort taken away from performing management actions. We developed a method to estimate invasive species abundance, evaluate management effectiveness, and evaluate population growth over time from a combination of removal activities (e.g., trapping, ground shooting) using only data collected during removal efforts (method of removal, date, location, number of …

Sex-Related Differences In Aging Rate Are Associated With Sex Chromosome System In Amphibians, Hugo Cayuela, Beth Reinke, 48 Other Co-Authors

Biology Faculty Publications

Sex-related differences in mortality are widespread in the animal kingdom. Although studies have shown that sex determination systems might drive lifespan evolution, sex chromosome influence on aging rates have not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with heterogametic males) and ZW (heterogametic females) systems. Taking advantage of a unique collection of capture–recapture datasets in amphibians, a vertebrate group where XY and ZW systems have repeatedly evolved over the past 200 million years, we examined whether sex heterogamy can predict sex differences in aging rates and lifespans. We showed …

Singing Strategies Are Linked To Perch Use On Foraging Territories In Heart-Nosed Bats, Grace C. Smarsh, Ashley M. Long, Michael Smotherman

Faculty Publications

Acoustic communication allows animals to coordinate and optimize resource utilization in space. Cardioderma cor, the heart-nosed bat, is one of the few species of bats known to sing during nighttime foraging. Previous research found that heart-nosed bats react aggressively to song playback, supporting the territorial defense hypothesis of singing in this species. We further investigated the territorial defense hypothesis from an ecological standpoint, which predicts that singing should be associated with exclusive areas containing a resource, by tracking 14 individuals nightly during the dry seasons in Tanzania. We quantified the singing behavior of individuals at all perches used throughout the …

Conservation, Comparative Genomics And Species Delimitation Of The Reindeer Lichens (Cladonia), Jordan R. Hoffman

Dissertations, Theses, and Capstone Projects

The genus Cladonia represents one of the most speciose genera of lichenized fungi, with more than 500 known species encompassing a diverse array of morphologies and habits. These lichens form keystone species in many habitats, serving a variety of ecological roles. However, despite being among of the more well studied lichens, there is much still unknown or under-studied about them. As is the case with most lichen study systems, phylogenetic study has been limited to a small number of partial loci, while adoption of next-generation sequence methods has been slow. As a consequence, there are still knowledge gaps in Cladonia …

Understanding Species Interactions And Their Impacts In Restored Communities, Jennifer Zhu

Species interactions may mediate the ability of organisms to survive in a community and provide valued services but are rarely fully considered in restoration planning. To address this, I considered how service provisioning will change as restored marsh communities mature and the value of incorporating antipredator training into captive-rearing programs.

For chapter 1, I explored how a facultative mutualism between Atlantic ribbed mussels Geukensia demissa and cordgrass Spartina alterniflora may enhance marsh growth and nitrogen cycling in a eutrophic setting. I created experimental plots in Jamaica Bay, NY, that contained live mussels, mussel shells, or no mussels (control) and measured …
