Abstract Wildlife must adapt to human presence survive in the Anthropocene, so it is critical understand species responses humans different contexts. We used camera trapping as a lens view mammal changes activity during COVID-19 pandemic. Across 163 sampled 102 projects around world, amount and timing of animal varied widely. Under higher activity, mammals were less active undeveloped areas but unexpectedly more developed while exhibiting greater nocturnality. Carnivores most sensitive,...
ABSTRACT Motivation SNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing dataset intended for tracking spatial and temporal responses mammal populations to changes in land use, cover climate. These data will be useful exploring drivers relative abundance distribution, as well impacts species interactions on daily activity patterns. Main Types Variables Contained 2019–2023 contains 987,979 records image sequence 9694 deployment...
Abstract SNAPSHOT USA is a multicontributor, long‐term camera trap survey designed to mammals across the United States. Participants are recruited through community networks and directly website application ( https://www.snapshot-usa.org/ ). The growing Snapshot dataset useful, for example, tracking wildlife population responses land use, cover, climate changes spatial temporal scales. Here we present 2021 dataset, third national US. Data were collected 109 arrays included 1711 sites. total...
Abstract The occurrence of additive genetic variance (VA) for male sexual traits remains a major problem in evolutionary biology. Directional selection normally imposed by female choice is expected to reduce VA greatly, yet recent surveys indicate that substantial amount many species. We addressed this problem, also known as the ‘lek paradox’, Achroia grisella (Lepidoptera: Pyralidae), an acoustic moth which males advertise females with pulsed ultrasonic song. Using standard...
Abstract Basic economic models adapted from foraging theory predict that decisions in mate choice may be determined either by ‘best‐of‐n’ preference functions or sequential rules incorporating acceptance thresholds. However, some species, more complex determinations incorporate versions of both protocols are found. To understand the co‐occurring protocols, we studied mating lesser wax moth, Achroia grisella (Lepidoptera: Pyralidae), an acoustic species which females prefer males,...
Abstract Leptospirosis is a water borne zoonotic disease of global significance that caused by pathogenic species the genus Leptospira . Pathogenic leptospires live in kidneys reservoir or infected animals and are shed their urine contaminating water, soil, etc. Rodents considered primary leptospirosis, but little known about role herpetofauna (non‐avian reptiles amphibians) epidemiology disease. To address this, various amphibians Cumberland Gap Region Central Appalachia were screened for...
Leptospirosis is a widespread zoonotic disease that causes reproductive losses and/or hepatorenal failure in number of animal species. Wild reservoirs the disease, such as rodents, harbor causative bacterium, Leptospira spp., their kidneys and contaminate environment by excreting infected urine. In this study, we tested small wild mammals, environmental water, livestock Cumberland Gap region southeastern Appalachia for presence pathogenic or leptospiral antibodies.Small mammals (n = 101)...
Maderas Rainforest Conservancy (MRC) was incorporated as a conservation nonprofit organization in 2008, and manages two sites where biological field courses have been offered since the 1990s: La Suerte Biological Research Station Costa Rica, Ometepe Nicaragua. MRC employs One Health approach to education, can serve model for other sites. The Nicaraguan Molina family, who owns sites, partnered with primatologist Paul Garber 1994 develop primate course aimed at introducing university students...
