recommendations! Published in 2025 at "JAMA Network Open"

DOI: 10.1001/jamanetworkopen.2025.1759

Abstract: Key Points Question Is the population size from which donor organs can be allocated associated with liver transplant waiting list outcomes for critically ill candidates in the US? Findings In a cohort study of 10 486… read more here.

DOI: 10.1002/ece3.11352

Abstract: Abstract Population size is a key parameter for the conservation of animal species. Close‐kin mark‐recapture (CKMR) relies on the observed frequency and type of kinship among individuals sampled from the population to estimate population size.… read more here.

DOI: 10.1002/ece3.5134

Abstract: Abstract Aerial distance sampling of bears to estimate population size has been used throughout many parts of Alaska. The distance sampling models are complex since they need to account for undetected bears and differences in… read more here.

DOI: 10.1002/ece3.5139

Abstract: Abstract To successfully perform their long‐distance migrations, migratory birds require sites along their migratory routes to rest and refuel. Monitoring the use of so‐called stopover and staging sites provides insights into (a) the timing of… read more here.

DOI: 10.1002/ece3.9778

Abstract: Abstract Understanding historical range shifts and population size variation provides an important context for interpreting contemporary genetic diversity. Methods to predict changes in species distributions and model changes in effective population size (N e) using… read more here.

recommendations! Published in 2017 at "Ecosphere"

DOI: 10.1002/ecs2.1747

Abstract: Estimating density and population size is often more challenging than measuring indices of abundance because of uncertainty about the effective area of surveys. We combined hierarchical modeling of detection/non-detection data from camera stations with auxiliary… read more here.

recommendations! Published in 2020 at "Ecology"

DOI: 10.1002/ecy.3024

Abstract: Individual variation in reproductive ability is a key component of natural selection within populations, driving the evolution of life histories and population responses to changing environmental conditions. Evidence that population density affects individual-level fitness in… read more here.

recommendations! Published in 2025 at "Veterinary Medicine and Science"

DOI: 10.1002/vms3.70684

Abstract: ABSTRACT Background Understanding the structure of linkage disequilibrium (LD) and accurately estimating the effective population size (Ne) are crucial for maintaining genetic diversity and ensuring population survival. These metrics are vital for decision‐making in conservation… read more here.

recommendations! Published in 2024 at "Wildlife Biology"

DOI: 10.1002/wlb3.01295

Abstract: Psittaciformes are among the most threatened birds, and population size and trend estimates are needed to aid conservation. The burrowing parrot Cyanoliseus patagonus is undergoing substantial changes in its population size, due to habitat degradation,… read more here.

Relationships between population size and fitness in four common and four rare alpine plant species

recommendations! Published in 2025 at "Alpine Botany"

DOI: 10.1007/s00035-025-00328-0

Abstract: Due to habitat fragmentation and climate change, many plant populations become smaller and more isolated and thus more prone to local extinction. Whereas it is well established for lowland species that plants of small populations… read more here.

DOI: 10.1007/s00442-018-4152-0

Abstract: Assessing genetic diversity within populations of rare species and understanding its determinants are crucial for effective species protection. While a lot is known about the relationships between genetic diversity, fitness, and current population size, very… read more here.
