Annual survival in a dynamic species: pronghorn survival patterns across their northern range

Wildlife Biology, EarlyView.
Quantifying variation in demographic patterns, such as survival and recruitment, is critical for understanding population dynamics and informing evidence‐based and adaptive wildlife management. In this study, we leverage an extensive dataset from over 1000 GPS collared pronghorn Antilocapra americana to provide the first large‐scale evaluation of ...

On monoids, 2-firs, and semifirs

, 2014
Several authors have studied the question of when the monoid ring DM of a monoid M over a ring D is a right and/or left fir (free ideal ring), a semifir, or a 2-fir (definitions recalled in section 1).

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Passive acoustic monitoring with AI‐based detection and identification reveal sooty grouse hooting patterns in western Oregon

Wildlife Biology, EarlyView.
Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

Wildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Detecting of Gunshots Direction Using TDOA (Time Difference of Arrival)

Emitor: Jurnal Teknik Elektro
In order to avoid shots being fired in undesirable areas, a device is required that can detect the origin of the shot so that the source of the bullet can be identified. This research was conducted to maintain the security and stability of a region.
