Abstract Human activity and land use change impact every landscape on Earth, driving declines in many animal species while benefiting others. Species ecological life history traits may predict success human‐dominated landscapes such that only with “winning” combinations of will persist disturbed environments. However, this link between successful coexistence humans remains obscured by the complexity anthropogenic disturbances variability among study systems. We compiled detection data for 24...
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...
Context Several studies have estimated cougar (Puma concolor) abundance using remote camera trapping in conjunction with capture–mark–recapture (CMR) type analyses. However, this methodology (photo-CMR) requires that photo-captured individuals are individually recognisable (photo identification). Photo identification is generally achieved naturally occurring marks (e.g. stripes or spots) unique to each individual. Cougars, however, uniformly pelaged, and photo must be based on subtler...
Abstract Aim The assembly of species into communities and ecoregions is the result interacting factors that affect plant animal distribution abundance at biogeographic scales. Here, we empirically derive for mammals to test whether human disturbance has become more important than climate habitat resources in structuring communities. Location Conterminous United States. Time Period 2010–2021. Major Taxa Studied Twenty‐five mammals. Methods We analysed data from 25 mammal recorded by camera...
Abstract Camera traps (CTs), used in conjunction with capture–mark–recapture analyses (CMR; photo‐CMR), are a valuable tool for estimating abundances of rare and elusive wildlife. However, critical requirement photo‐CMR is that individuals identifiable CT images (photo‐ID). Thus, generally limited to species conspicuous pelage patterns (e.g., stripes or spots) using lateral‐view from CTs stationed along travel paths. Pumas ( Puma concolor ) an which highly effective at collecting image data,...
Background: The psychostimulant drugs, cocaine and methamphetamine, are potent, indirect dopamine receptor agonists. Sustained use of high doses these drugs can result in psychotic symptoms a large proportion individuals. However, there is shortage information about how this type drug-induced psychosis compares to the associated with schizophrenia spectrum disorders. aim present study was compare cocaine- or methamphetamine-dependent subjects vs disorder, cohort living common environment....
