Anti-Bat Ultrasound Production In Moths Is Globally And Phylogenetically Widespread, Jesse R. Barber, Brian C. Leavell, Krystie A. Miner, Brandt Quirk-Royal

Warning signals are well known in the visual system, but rare in other modalities. Some moths produce ultrasonic sounds to warn bats of noxious taste or to mimic unpalatable models. Here, we report results from a long-term study across the globe, assaying moth response to playback of bat echolocation. We tested 252 genera, spanning most families of large-bodied moths, and document anti-bat ultrasound production in 52 genera, with eight subfamily origins described. Based on acoustic analysis of ultrasonic emissions and palatability experiments with bats, it seems that acoustic warning and mimicry are the raison d'être for sound production in most …

Effects Of Patch Size, Fragmentation, And Invasive Species On Plant And Lepidoptera Communities In Southern Texas, James A. Stilley, Christopher A. Gabler

Biology Faculty Publications and Presentations

---

Simple Summary

Human land use has removed habitats, separated habitats into small and disconnected fragments, and introduced foreign species, which all harm wildlife. South Texas is highly diverse and home to many endangered species, but human disturbance threatens its wildlife. In south Texas, we poorly understand how different aspects of human land use influence wildlife diversity and abundance. We studied this by surveying plants and butterflies in 24 habitat fragments in south Texas that differed in size, shape, type, and land use history. Human disturbance was extensive, and foreign and weedy species were dominant in most habitats. Habitat types had …

Biodiversity science encompasses multiple disciplines and biological scales from molecules to landscapes. Nevertheless, biodiversity data are often analyzed separately with discipline-specific methodologies, constraining resulting inferences to a single scale. To overcome this, we present a topic modeling framework to analyze community composition in cross-disciplinary datasets, including those generated from metagenomics, metabolomics, field ecology and remote sensing. Using topic models, we demonstrate how community detection in different datasets can inform the conservation of interacting plants and herbivores. We show how topic models can identify members of molecular, organismal and landscape-level communities that relate to wildlife health, from gut microbes to forage …

Rivfishtime: A Global Database Of Fish Time-Series As A Currency For Global Change Ecology Research In Riverine Systems, Lise Comte, Juan Carvajal-Quintero, Pablo A. Tedesco, Ulrich Brose, Tibor Erős, Ana F. Filipe, Marie-Josée Fortin, Katie Irving, Claire Jacquet, Christopher M. Taylor

Motivation

We compiled a global database of long-term riverine fish surveys from 46 regional and national monitoring programmes and from individual academic research efforts, with which numerous basic and applied questions in ecology and global change research can be explored. Such spatially and temporally extensive datasets have been lacking for freshwater systems in comparison to terrestrial ones.

Main types of variables contained

The database includes 11,386 time-series of riverine fish community catch data, including 646,270 species-specific abundance records, together with metadata related to the geographical location and sampling methodology of each time-series.

Spatial location and grain

The database contains 11,072 …

A First Phylogenetic Assessment Of Dictyonemo S.Lat In Southwestern North America Reveals Three New Basidiolichens, Described In Honor James D. Lawrey, Manuel Dal Forno, Laurel Kaminsky, Roger Rosentreter, R. Troy Mcmullin, André Aptroot, Robert Lücking

Three species of lichenized basidiomycetes in the Dictyonema clade from southeastern North America are described as new to science: Cyphellostereum georgianum, C. jamesianum and Dictyonema lawreyi, all with a crustose-filamentous growth form. Based on ITS sequences, the species form well-supported monophyletic clades in a phylogeny and are represented by at least two specimens each. They are also distinguishable by morphological and anatomical characters. These new findings emphasize the importance of lichenological studies in North America, especially in historically understudied taxonomic groups, such as basidiolichens. This study is dedicated to James D. Lawrey on the occasion of his 70^{th …}

Phylogeny Of The Ciliate Family Psilotrichidae (Protista, Ciliophora), A Curious And Poorly-Known Taxon, With Notes On Two Algae-Bearing Psilotrichids From Guam, Usa, Xiaotian Luo, Jie A. Huang, Lifang Li, Weibo Song, William A. Bourland

Background: The classification of the family Psilotrichidae, a curious group of ciliated protists with unique morphological and ontogenetic features, is ambiguous and poorly understood particularly due to the lack of molecular data. Hence, the systematic relationship between this group and other taxa in the subclass Hypotrichia remains unresolved. In this paper the morphology and phylogenetics of species from two genera of Psilotrichida are studied to shed new light on the phylogeny and species diversity of this group of ciliates.

Results: The 18S rRNA gene sequences of species from two psilotrichid genera were obtained. In the phylogenetic trees, the available psilotrichid …

Arthropod Abundance And Diversity In Street Trees Of South Texas, Usa, Alexis Racelis, Ann T. Vacek, Carol Goolsby, John Brush, John A. Goolsby

In urban areas, street trees provide a variety of ecological services, including biodiversity conservation. In this study we examined arthropod diversity on native and non-native street trees sampled during the fall of 2010 and spring of 2011 in McAllen, Texas, one of the most rapidly growing urban areas in the country. Eighty-eight street trees were sampled by removing arthropods from the lower canopy foliage using a hand held vacuum. Arthropods were collected into nylon bags, identified to order, and counted by morphospecies. Overall, street trees supported a significant and diverse population of arthropods: a total of 1,971 arthropods were collected, …
