Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Correlation Analysis among the Various Inbreeding Coefficients of Pannon Ka Rabbits

Diversity
In a closed population with a limited population size, mating of related animals is unavoidable. In this study, the genealogy data of a synthetic maternal rabbit breed called Pannon Ka were used to calculate different inbreeding coefficients.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

Incestuous sisters: mate preference for brothers over unrelated males in Drosophila melanogaster.

PLoS ONE, 2012
The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny.

Long‐term patterns of breeding range expansion mirror invasion dynamics during recolonisation of a semi‐colonial raptor

Journal of Animal Ecology, EarlyView.
We used a unique long‐term dataset of population recovery in the Osprey Pandion haliaetus to reveal the similarity in spatial patterns underpinning recolonisations and biological invasions. Our findings highlight the importance of rare pioneering movements in driving range expansion, and the value of conservation interventions such as species ...

Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populations

Ecology and Evolution, 2019
Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations ...

Understanding natal emigration in group‐living carnivores

Journal of Animal Ecology, EarlyView.
Dispersal is a key ecological and evolutionary process, yet drivers of variation in emigration under human‐modified conditions remain understudied. Using a novel genetic approach applied to harvested grey wolves in Idaho, USA, we found that prey availability and population density shape natal emigration patterns in a cooperative breeder.

The evolutionary ecology of inbreeding depression in wild plant populations and its impact on plant mating systems

Frontiers in Plant Science
Inbreeding depression, the reduced fitness of inbred relative to outbred individuals was described more than two centuries ago, long before the development of population genetics.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Inbreeding depression in the Lizard canary breed estimated by pedigree analysis

Czech Journal of Animal Science, 2016
The influence of inbreeding depression on phenotypic traits of the Lizard canary from an Italian breeder was evaluated. The following traits were studied: birds' life span, number of surviving offspring, and morphological traits (type of plumage ...
