Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

open access: yesWildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

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

open access: yesWildlife 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

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Design considerations for breeding waterfowl surveys

open access: yesWildlife Society Bulletin, EarlyView.
This study evaluated how different survey designs affect the accuracy and precision of breeding waterfowl population estimates in Iowa's Prairie Pothole Region. Using aerial survey data from 2016–2018, we found that conducting at least 2 visits per season reduced bias in pair estimates, particularly for wood ducks and blue‐winged teal, while mallard ...

Multiple signalling increases both prey response and diversity in a carnivorous pitcher plant

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organisms across the tree of life use multiple signals such as colour, movement sound, and many types of chemical signals to convey seemingly the same information. These signals are potentially costly, yet the repeated evolution of multiple signalling across systems ...
