Do you see what I see? Variation in detection, identification and enumeration of mammals during transect surveys

“…The effectiveness of driven transects for establishing species community in an ecologicallymeaningful way has been shown previously for detection of nocturnal mammals (Hart et al, 2022).…”

“…Given that walked transects are physically demanding, cover substantially less ground than driven surveys per unit time and record fewer sightings per survey, we suggest driven transects be used for surveys of African land mammals if tracks and vehicle resources are available. The effectiveness of driven transects for establishing species community in an ecologically meaningful way has been shown previously for the detection of nocturnal mammals (Hart et al, 2022).…”

A unifying framework for understanding ecological and evolutionary population connectivity

“…Tracking involves sampling the same individual organism through time, sometimes through the use of transmitting, or "active" devices such as satellite tags (Kool et al, 2013;Hussey et al, 2015;Kays et al, 2015). Surveys establish the presence of an individual or a group in a location, but do not necessarily track specific individuals across time (Burton et al, 2015;Supp et al, 2021;Hart et al, 2022). A single survey of whales, for example, may identify individuals at a location, but there is no guarantee the same individuals will be present to provide data on the next survey.…”

Complementarity between mist-netting and low-cost acoustic recorders to sample bats in Amazonian rainforests and savannahs

“…Quantifying changes in wildlife communities is a key challenge in the Anthropocene, requiring efficient and cost-effective survey methods (Hart et al 2022). South and Central America constitute the planet's epicentre of bat diversity with over 300 species and 80 genera (Wilson and Mittermeier 2019).…”
