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...
The nine-banded armadillo (Dasypus novemcinctus: hereafter armadillo) was first recorded in the United States (U.S.) state of Texas 1849 and has been expanding its range northward eastward since then. With widespread adoption participatory science as well proliferation nationwide wildlife game camera studies, occurrence data armadillos can be compiled more rapidly thoroughly than at any time past. Here, we use disparate sources to update current geographic distribution from leading edge...
Identifying nest predators is of fundamental importance to understanding avian breeding ecology and can contribute identifying broadscale nest-predation patterns. We reviewed 53 North American nest-predator studies, comprising more than 4000 camera-monitored nests, explore geographic patterns in predator identity how predation varied with richness, habitat, height, bird size. Overall, mesopredators (at high latitudes) snakes low were the most frequent guilds. Predation by rodents was...
1 Anthropogenic alteration of landscapes can affect avian nest success by influencing the abundance, distribution, and behavior predators. Understanding predation risk necessitates understanding how predator distribution behavior. 2 From a sample 463 nests 17 songbird species, we evaluated landscape features (distance to forest edge, unpaved roads, power lines) influenced daily survival. We also used video cameras identify predators at 137 events identity. Finally, determined abundance...
Predation is the leading cause of nest failure for most birds. Thus, ornithologists interested in causes and consequences variation success, knowing identity understanding behavior dominant predators likely to be important. Video documentation nests has shown that snakes are frequent predators. Here we reviewed 53 North American studies used cameras these data identify broad patterns snake predation. Snakes accounted 26% (range: 0–90%) recorded predation events, with values exceeding 35% a...
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...
Diurnal basking ("sunning") is common in many ectotherms and generally thought to be a behavioural mechanism for thermoregulation. Recent studies have reported the occurrence of nocturnal few distantly-related species freshwater turtles, but true extent this behaviour unknown, it may underreported due sampling biases (e.g., not surveying turtles at night). Therefore, we initiated global, collaborative effort systematically document quantify activity (diurnal nocturnal) across wide range...
The Nine-banded Armadillo (Dasypus novemcinctus) is a widespread burrowing species with an expanding geographic range across the southeastern and midwestern United States. Armadillos dig numerous, large burrows within their home ranges these are likely used by diverse suite of wildlife as has been reported for other ecosystem engineers such Gopher Tortoises (Gopherus polyphemus), Desert agassizi), Black-tailed Prairie Dogs (Cynomys ludovicianus). We motion-triggered game cameras at 35...
Miniature temperature loggers were used to better understand the incubation temperatures, patterns in metabolic heating, and potential implications for sex determination of relocated situ loggerhead sea turtle clutches near northern extent their nesting range. All turtles display temperature-dependent determination, with cooler nests producing males warmer females. Analysis factors that affect temperatures provides insight into variation hatchling ratios over temporal spatial scales may help...
Urbanization has profound effects on the presence and distribution of wildlife species. Although numerous studies have been conducted to inform our understanding urbanization wildlife, urban communities in tropics are especially rare. Here, we investigated bird community assemblage at an military installation, Fort Buchanan, located within San Juan Metropolitan Area Caribbean island Puerto Rico. Using fixed-radius point count surveys opportunistic encounters, documented over 1,700 individual...
Abstract Recovery plans for the Endangered loggerhead marine turtle Caretta caretta cite mammalian predation as a major threat, and recommend nest protection efforts, already present at many rookery beaches, to protect eggs hatchlings. Nest techniques vary but wire box cages plastic mesh screens are two common tools used deter by host of beach-foraging, opportunistic predators. We empirically tested efficacy in preventing red fox Vulpes vulpes on artificial nests. Both averted (0%), whereas...
Raising captive animals past critical mortality stages for eventual release (head-starting) is a common conservation tactic. Counterintuitively, post-release survival can be low. Post-release behavior affecting could influenced by captive-rearing duration and housing conditions. Practitioners have adopted environmental enrichment to promote natural behaviors during head-starting such as raising in naturalistic enclosures. Enrichment might especially beneficial held captivity long-term...
Abstract As the human footprint upon landscape expands, wildlife seeking to avoid contact are losing option of altering their spatial distribution and instead shifting daily activity patterns be active at different times than humans. In this study, we used game cameras evaluate how development were related nine‐banded armadillo ( Dasypus novemcinctus) along an urban rural gradient in Arkansas, USA during winter 2020–2021. We found that armadillos had substantial behavioral plasticity regard...
Abstract The human footprint is rapidly expanding, and wildlife habitat continuously being converted to residential properties. Surviving that reside in developing areas are displaced nearby undeveloped areas. However, some animals can co-exist with humans acquire the necessary resources (food, water, shelter) within environment. This ability coexist may be particularly true when development low intensity, as suburban yards. Yards individually managed “greenspaces” provide a range of food...
Abstract Decisions affecting wildlife management and conservation policy of imperiled species are often aided by population models. Reliable models require accurate estimates vital rates an understanding how vary geographically. The eastern massasauga ( Sistrurus catenatus ) is a rattlesnake found in the Great Lakes region North America. Populations fragmented only few areas harbor multiple, sizable populations. Eastern research has typically focused on single populations or local...
Context Wildlife translocation is a conservation tool with mixed success. Evidence suggests that longer time in captivity may negatively affect an animal’s post-release behaviour and survival. However, environmental enrichment reduce the deleterious effects of for animals are going to be released into wild. Aims The aim present study was compare first-year survival translocated ratsnakes (Pantherophis obsoletus) held captive varying durations (1–7 years) either or without enrichment,...
Abstract Avian nest success often varies seasonally and because predation is the primary cause of failure, seasonal variation in predator activity has been hypothesized to explain success. Despite fact that communities are diverse, recent evidence from studies snakes predators lent some support link between snake predation. However, strength relationship varied among studies. Explaining this difficult, none these directly identified predators, survival was inferred. To address knowledge gap,...
Abstract Annually, millions of snakes are killed on roads in the United States. Because their potential abundance and ease collection, many researchers have used road-killed to examine community composition, movement patterns, population dynamics. However, few previous studies accounted for snake carcasses that removed from by scavengers. Snake were placed at randomly selected locations along 2 km road, one traversing maritime forest other surrounded dune habitat. Carcasses forested habitat...
Abstract Predation involves costs and benefits, so predators should employ tactics that reduce their risk of injury or death increase success at capturing prey. One potential way could decrease benefits is by attacking prey night when risks may be reduced more vulnerable. Because some snakes are facultatively nocturnal on bird nests during the day night, they ideal for assessing diurnal vs. predation. We used automated radiotelemetry cameras to investigate predation nesting birds two species...
