Scale Dependent Temporal and Spatial Patterns of Population Change in Anadromous Sea Trout (Salmo trutta) in Scotland Over Seven Decades

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT The spatial scale at which temporal change in a population is measured has the potential to skew the inferences drawn on patterns of change from monitoring data. This study analysed data from rod catches of anadromous sea trout (Salmo trutta) in Scotland over 72 years and three spatial scales (National, Regional and District).

Female philopatry and its social benefits among Bornean orangutans [PDF]

, 2012
Female philopatry in mammals is generally associated with ecological and sometimes social benefits, and often with dispersal by males. Previous studies on dispersal patterns of orangutans, largely non-gregarious Asian great apes, have yielded conflicting

Collectivism–Individualism, Family Ties, and Philopatry [PDF]

, 2014
As predicted by the parasite-stress theory of values, variation in parasite stress correlated with collectivism–individualism across nations, USA states, and indigenous societies. In regions with high adversity of infectious diseases, human cultures are characterized by high collectivism, whereas in regions of low parasite stress cultures are highly ...

In and out: factors influencing two decades of straying and homing by Pacific salmon within the Columbia River basin

Royal Society Open Science
In addition to patch size and spatial isolation, habitat quality can also influence attractiveness of patches to dispersing individuals. Using mark recapture data from 19 populations of Chinook salmon (Oncorhynchus tshawytscha) across 23 years in the ...

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, Volume 168, Issue 4, Page 1378-1390, October 2026.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, Volume 168, Issue 4, Page 1210-1229, October 2026.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Evidence of Intraspecific Brood Parasitism and Abnormal Egg-Laying Behavior in the Lesser Kestrel (Falco naumanni)

Birds
Intraspecific brood parasitism (IBP), where one female lays eggs in another’s nest, is considered rare in raptors, including typically monogamous and solitary or semi-colonial falcons. The Lesser Kestrel (Falco naumanni) is a colonial falcon with a usual

Genetic isolation and morphological divergence mediated by high-energy rapids in two cichlid genera from the lower Congo rapids

BMC Evolutionary Biology, 2010
Background It is hypothesized that one of the mechanisms promoting diversification in cichlid fishes in the African Great Lakes has been the well-documented pattern of philopatry along shoreline habitats leading to high levels of genetic isolation among ...

Insights into reproduction and behavior of the smalltooth sawfish Pristis pectinata

Endangered Species Research, 2017
Sawfishes (Family Pristidae) constitute one of the most threatened families of marine fish, and substantial management efforts are required to stabilize and recover their populations worldwide. Philopatry is common in marine animals, including sharks and
