Offspring Dependency Is Not Reflected in the Social Immunity of Three Burying Beetle Species

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 625-638, July 2026.
Nicrophorus pustulatus, Nicrophorus vespilloides, and Nicrophorus orbicollis are three burying beetle species that differ both in their ecology and in the dependency of their offspring on parental care. This gradient of offspring dependency might be reflected in the parents' social immunity capabilities and/or investment.

Higher‐Order Interactions Can Promote Coexistence by Rewiring Intransitivities Into Competitive Networks

Ecology Letters, Volume 29, Issue 7, July 2026.
We integrate natural history and theory to show how higher‐order interactions (HOIs) can restructure competitive networks and influence coexistence in a tropical ant community. The HOI from a parasitoid of the dominant ant species forces the community to move between two dominance regimes, and the interregnum between regimes has multiple interacting ...

Environmental correlates of spatio‐temporal patterns of colour variation in a bird of prey: The common buzzard (Buteo buteo)

Ibis, Volume 168, Issue 3, Page 985-1001, July 2026.
High colour variability in animals has been associated with adaptability to environmental change. Establishing how such variability is distributed in time and space, and identifying environmental correlates, can help understand the processes driving it.

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

Ibis, Volume 168, Issue 3, Page 1085-1099, July 2026.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Unravelling the Genetic Mechanisms of Litter Traits in a Maternal Line of Pigs

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 560-580, July 2026.
ABSTRACT Reproductive traits related to litter size are the main indicators of reproductive efficiency in pig production and are continuously evaluated for the selection of maternal lines. Several environmental and genetic factors are involved with the development of these traits.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 602-612, July 2026.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Rural Capitalists and Development in Colonial Africa: A Comparative Analysis

Journal of Agrarian Change, Volume 26, Issue 3, July 2026.
ABSTRACT This paper explores the emergence and role of rural capitalists in colonial Sub‐Saharan Africa by comparing three peasant‐based economies: Bechuanaland, the Gold Coast and Tanganyika. Using social tables, we estimate the population and income shares of better earning agricultural producers and assess their impact on rural inequality and ...

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to
