Long-term demography of a reintroduced population of endangered falcons

Global Ecology and Conservation, 2022
We examined long-term demography of an endangered subspecies, the Northern Aplomado Falcon (Falco femoralis septentrionalis), in South Texas, USA. The population has been managed and monitored since reintroductions began in 1993.

An integrated model of territory occupancy and mark‐recapture data for estimating spatial variation in survival

Methods in Ecology and Evolution, EarlyView.
Abstract Spatial variation in survival is central to understanding population dynamics and guiding conservation. However, assessing it is hard, since capture‐mark‐recapture (CMR) data required for such inference must be collected over large spatial extents, which is seldom possible.

Is Gillnet Prey Subsidizing Ontogenetic Diet Shifts and Early Weaning in Common Coastal Bottlenose Dolphins From the Southwestern Gulf of Mexico?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Artisanal gillnet fisheries can concentrate prey and provide incidental food subsidies to marine predators, but their effects on early‐life foraging behavior and demography remain poorly resolved. The Alvarado bottlenose dolphin population that lives off the coast of Veracruz, Mexico, is well known for having chronic, frequent, and recurring ...

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

Ibis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

Anthropogenic and Environmental Factors Influence Kentish Plover (Anarhynchus alexandrinus) Survival in a Conservation-Reliant Coastal Population

Birds
Bird survival is influenced by both natural and anthropogenic factors, including weather conditions and oil spills. In this study, we examined the impact of a major oil spill (Prestige oil tanker) and climatic conditions (precipitation and wind) on ...

Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

Journal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

Challenges and opportunities for monitoring wild Nile crocodiles with scute mark-recapture photography

Koedoe: African Protected Area Conservation and Science, 2018
The global conservation status of Nile crocodiles (Crocodylus niloticus) was last assessed in 1996. The species presents particular difficulty in monitoring because it can be cryptic, require expertise to handle, and caudal tail tags and transmitters are
