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,...
Camera trapping is an effective non-invasive method for collecting data on wildlife species to address questions of ecological and conservation interest. We reviewed 2,167 camera trap (CT) articles from 1994 2020. Through the lens technological diffusion, we assessed trends in: (1) CT adoption measured by published research output, (2) topic, taxonomic, geographic diversification composition applications, (3) sampling effort, spatial extent, temporal duration studies. Annual publications...
Abstract The isotopic niche of consumers represents biologically relevant information on resource and habitat use. Several tools have been developed to quantify size overlap. Nonetheless, methods adapted by spatial ecologists animal home ranges can be modified for use in stable isotope ecology when data are not normally distributed bivariate space. We offer a tool that draws existing metrics, such as minimum convex polygon (MCP) standard ellipse area (SEA), add novel metrics using kernel...
Abstract With the accelerating pace of global change, it is imperative that we obtain rapid inventories status and distribution wildlife for ecological inferences conservation planning. To address this challenge, launched SNAPSHOT USA project, a collaborative survey terrestrial populations using camera traps across United States. For our first annual survey, compiled data all 50 states during 14‐week period (17 August–24 November 2019). We sampled at 1,509 trap sites from 110 arrays covering...
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...
Recently, it was proposed that stable isotope patterns can be used to quantify the width of ecological niche animals. However, potential effects habitat use on isotopic consumers have not been fully explored and consequently may yield deceptive estimates width. Here, we simulated four different scenarios a consumer foraging across an isotopically heterogeneous landscape test combined diet selection widths niche. We then modeled actions naïve researcher who randomly sampled from populations,...
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...
Managing wildlife populations in the face of global change requires regular data on abundance and distribution wild animals, but acquiring these over appropriate spatial scales a sustainable way has proven challenging. Here we present from Snapshot USA 2020, second annual national mammal survey USA. This project involved 152 scientists setting camera traps standardized protocol at 1485 locations across 103 arrays 43 states for total 52,710 trap-nights effort. Most (58) were also sampled...
Abstract The Florida spotted skunk ( Spilogale putorius ambarvalis ) is disjunct from other eastern S. subspecies and has rarely been studied. Declines in populations elsewhere underscore the importance of better understanding subspecies’ ecology resource use, including its potential impacts as a nest predator imperiled ground-nesting birds. objective our study was to gather baseline information on diet dry prairie ecosystem Central Florida. We conducted stable isotope analysis using hair...
Where dispersal is energetically expensive, feeding and food availability can influence success. The endemic Prince of Wales northern flying squirrel (Glaucomys sabrinus griseifrons) inhabits a landscape mosaic old-growth, 2nd-growth, clear-cut stands, with the latter 2 representing expensive habitats. We estimated diet squirrels using stable isotope fecal analyses, determined whether varies among forest assessed likelihood foraging across managed given distribution foods on Island (POW),...
ABSTRACT A new movement to develop course‐based undergraduate research experiences (CURE) is emerging, although the benefits of such programs have not yet been fully evaluated. We examined effects a field‐based CURE project on science attitudes, career choice, and perceived knowledge wildlife students ( n = 32) at University Wyoming in 2012. In this project, junior senior gained practical experience, used their own data learn various modeling approaches, disseminated results orally written...
Connections, collaborations, and community are key to the success of individual scientists as well transformative scientific advances. Intentionally building these components into science, technology, engineering mathematics (STEM) education can better prepare future generations researchers. Course-based undergraduate research experiences (CUREs) a new, fast-growing teaching practice in STEM that expand opportunities for students gain skills. Because they engage all course an authentic...
Successful dispersal in many species may be a function of the distance at which animals can perceive particular landscape feature (i.e., perceptual range), as well energetic costs associated with traversing towards that feature. We used model, relating range to body size mammals, predict northern flying squirrel ( Glaucomys sabrinus (Shaw, 1801)) fragmented forests Southeast Alaska. hypothesized squirrels would 325.5–356.5 m clearcuts and 159.7–174.9 second-growth stands. The advantage may,...
For decades, ecologists have debated the importance of biotic interactions (e.g., competition) and abiotic factors in regulating populations. Competition can influence patterns distribution, abundance, resource use many systems but remains difficult to measure. We quantified competition between two sympatric small mammals, Keen's mice (Peromyscus keeni) dusky shrews (Sorex monticolus), four habitat types on Prince Wales Island Southeast Alaska. related shrew density that using standardized...
We evaluated gliding, climbing, and running performance by Petaurus norfolcensis in southern Queensland, Australia a laboratory colony of P. breviceps. The data were used to test the hypothesis that gliding locomotion is energetically less expensive than quadrupedal transport, thus reasonable explanation for evolution gliding. Gliding transport only when able climb launch point rapidly. found no conditions which was compare these results with published on North American flying squirrels,...
Core Ideas Undergraduate students benefit by attending conferences and interacting with professionals. Active mentoring support before, during, after a conference increases student confidence. Students gained sense of belonging, social benefits, career confirmation through the course. Developing professional relationships likely leads to increased retention This course focused on in natural resource environmental sciences, but structure is easily transferrable other disciplines. Scientific...
Consumption of weed seeds and waste grains by seed predators is an important ecosystem service that helps to regulate volunteer crop populations in many agricultural systems. The prairie deer mouse found a variety sparsely vegetated habitats throughout the central United States dominant vertebrate predator row-crop fields (corn soybean) this region. Evaluating preferences mice for common grain understand potential ability native crops populations. We evaluated winter preference using...
Severe population declines in numerous North American bat species makes monitoring increasingly difficult. We tested the effectiveness of an acoustic lure at increasing capture success bats mist nets. Increasing detection rate is especially relevant for that have been heavily affected by white-nose syndrome, such as Indiana (Myotis sodalis), little brown (M. lucifugus), and northern long-eared septentrionalis). conducted our study 3 properties southern during summer 2014. set up 7...
Although course-based undergraduate research experiences (CUREs) are gaining popularity in biology, most designed for benchwork-based laboratory courses while few focus on field-based skills. Many barriers to implementing field CUREs exist, including the difficulty designing authentic that can be accomplished a limited lab timeframe, permitting and liability issues, problems gathering sufficient data meaningfully analyze. Squirrel-Net (http://squirrel-net.org) is consortium of mammalogists...
