The costs of extra‐pair behaviours in birds

Biological Reviews, Volume 101, Issue 5, Page 2300-2312, October 2026.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Urbanisation Leaves a Genetic Signature but No Detectable Demographic Effects in a Small Mammal Population

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Urbanisation can alter both genetic connectivity and demographic performance of wildlife populations, but these responses may occur on different temporal scales. Using multi‐year capture‐mark‐recapture data and microsatellite analyses of Eurasian red squirrels across an urbanisation gradient in Berlin, we found subtle genetic structuring without clear ...

INBREEDING DEPRESSION FOR YIELD AND YIELD COMPONENTS IN Fragaria × ananassa Duch.

Acta Scientiarum Polonorum: Hortorum Cultus, 2012
In case of plants, inbreeding depression can be measured through comparison of the fitness of selfed individuals with outcrossed individuals. In this paper the effect of repeated inbreeding on fruit yield and yield component of strawberries (Fragaria ...

Long‐distance pollen transport mediated by migratory hoverflies

Ecography, Volume 2026, Issue 10, October 2026.
Long‐distance animal migrations shape ecosystems by redistributing nutrients, connecting populations, and mediating ecological interactions. However, the ecological contributions of many abundant insect migrants remain poorly quantified. Hoverflies are among the most numerous migratory insects and highly efficient pollinators, suggesting that their ...

Double mutualism: Dual rewards or redundancy? Insights from the interactions between mistletoes and their avian partners

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract Mistletoes, recognized as keystone species, supply diverse floral and fruit resources for birds, thereby facilitating mutualistic interactions in pollination and seed dispersal. Some avian species are “double mutualists,” engaging in both functions. However, their precise roles and effectiveness as mutualists remain inadequately understood. In

Early Contributions Leading to Understanding the Significance of Epichloë Endophyte in Temperate Grasses

New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

Oikos, Volume 2026, Issue 10, October 2026.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context

Inbreeding Depression and Heterosis

The assessments of heterosis and inbreeding depression together provide information about the gene action involved in the expression of different polygynous traits, hence for plant breeders. Knowledge of hybrid vigour and inbreeding decline is essential.

Five‐year assessment of wolf translocation to Isle Royale National Park, 2018–2023

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
The National Park Service used a variety of methods to monitor the success of a restored wolf population on Isle Royale National Park. Abstract Gray wolf (Canis lupus) translocation is a common approach for restoring ecological function through top‐down regulation.

Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...
