Population time series analysis is an integral part of conservation biology in the current
context of global changes. To quantify changes in population size, wildlife counts only …

Species' population trends are fundamental to conservation. They are used to determine the
state of nature, and to prioritize species for conservation action, for example through the …

Long-term time series are necessary to better understand population dynamics, assess
species' conservation status, and make management decisions. However, population data …

Seven observers independently sampled the bird assemblage in oak-pine woodlands in
central California by completing 5-min point counts at 210 counting stations during April …

Population monitoring programmes typically rely on sampling because it is impossible to
survey all the sites within the study area. In such a situation, the general recommendation to …

Summary 1 Studies aiming to identify the prevalence and nature of density dependence in
ecological populations have often used statistical analysis of ecological time‐series of …

We recently published a study discussing the pitfalls of non‐probability sampling when
selecting monitoring sites. We demonstrated that selecting sites based on abundance can …

Knowing the parameters of population growth and regulation is fundamental for answering
many ecological questions and the successful implementation of conservation strategies …

Site selection bias can occur when researchers monitor animals at sites of great abundance,
occupancy or quality. The prevailing heuristic is therefore that ecologists should never select …

Abstract Information on change in population size over time is among the most basic inputs
for population management. Unfortunately, population changes are generally difficult to …
