Urbanisation Leaves a Genetic Signature but No Detectable Demographic Effects in a Small Mammal Population [PDF]
Ecology and EvolutionUrbanisation influences ecological and evolutionary processes, including gene flow and survival. Understanding how genetic and demographic rates respond to urbanisation is therefore essential for predicting and managing wildlife viability in human ...

Understanding the impact of correlation within pair‐bonds on Cormack–Jolly–Seber models [PDF]
Ecology and Evolution, 2021 The Cormack–Jolly–Seber (CJS) model and its extensions have been widely applied to the study of animal survival rates in open populations. The model assumes that individuals within the population of interest have independent fates. It is, however, highly

Survival Estimation Using Multistate Cormack–Jolly–Seber Models—The Case of the Bearded Vulture Gypaetus barbatus in Spain [PDF]
AnimalsThe bearded vulture (Gypaetus barbatus) is an endangered species with a specialist osteophagous (bone) diet. We estimated the survival and productivity of this vulture in the Aragonese Pyrenees, where the main population of the species in Europe is found.

Estimating Survival, Growth, and Morphometric Relationships of Blue Crab (Callinectes sapidus) in North Carolina Using Mark–Recapture and Bayesian Approaches [PDF]
AnimalsSeveral of the North Carolina blue crab’s (Callinectes sapidus) life history parameters such as growth rate, natural mortality, and length–weight relationships would benefit from being updated or localized. To this end, we designed a mark–recapture study

Age-Specific Demographic Response of a Long-Lived Scavenger Species to Reduction of Organic Matter in a Landfill [PDF]
Animals, 2023 Food availability shapes demographic parameters and population dynamics. Certain species have adapted to predictable anthropogenic food resources like landfills. However, abrupt shifts in food availability can negatively impact such populations.

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi‐Year Study [PDF]
Ecology and EvolutionMale alternative reproductive tactics (ARTs) have been documented across diverse taxa and typically involve a male morph that defends resources to attract females and an alternate morph that exploits this behavior to obtain matings by stealth ...

Salmon Louse Infestation Impairs the Long‐Term Survival of Sea‐Run Brown Trout [PDF]
Ecology and EvolutionAnadromous salmonids, including sea‐run brown trout, are exposed to ectoparasitic salmon lice during their sea migrations. The development of intensive aquaculture in coastal areas has promoted louse epidemics by substantially increasing the number of ...

Demography and Behaviour of Teinopodagrion oscillans (Odonata: Megapodagrionidae) in a Protected Area of the Colombian Andean Region [PDF]
InsectsThe demography and behaviour of Teinopodagrion oscillans was studied in a protected area in the Andean region of Colombia. Adult damselflies were individually marked, and using their recapture histories, we estimated survival, longevity, sex ratio, and ...
