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.

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit (Parus major) territories across Europe

open access: yesJournal of Animal Ecology, EarlyView.
Across six European cities, great tits in more impervious territories had paler carotenoid‐based plumage, but not lower brightness or UV chroma. This suggests that urban habitat imperviousness is associated specifically with lower carotenoid pigment deposition, rather than broad changes in feather reflectance or structural quality.

Data from: Spatiotemporal variation of host use in a brood parasite: the role of the environment

open access: yes, 2016
Avian brood parasites should target the most profitable host species, but current conditions might locally influence their choice, producing geographic mosaics of coevolution.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect 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.

The influence of a fungal brood parasite on life-history traits of its Daphnia host

open access: yes, 2005
Daphnia parasites are known to affect different life-history traits of their host and by that to have an important influence on the host population. We investigated a fungal brood parasite and its implications on the Daphnia host.

Males are worse mothers: Comparing care patterns in a facultatively caring beetle

open access: yesInsect Science, EarlyView.
Why should biparental care exist if offspring fare just as well when only one parent is present? In the facultatively dependent burying beetle, Nicrophorus vespilloides, manipulating environmental quality reveals that biparental care benefits offspring in form of lower personal immune requirement and parents in term of weight gain.

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.
