Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

open access: yesJournal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Early‐life environment drives long‐term decrease in adult body mass in a wild bird population

open access: yesJournal of Animal Ecology, EarlyView.
Using more than 90,000 body mass measures of adult and nestling great tits Parus major, we show that the 1 SD decline in adult mass between 1978 and 2024 is a consequence of changes in the environment (i.e. increase in population density) experienced at early life.

Cryptic variation within and among islands in the ultraviolet reflectance of lizard throat coloration

open access: yesJournal of Animal Ecology, EarlyView.
Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

open access: yesInsect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.
