Effects of temperature and humidity on the presence and prevalence of a common fungal parasite on an invasive ladybird

open access: yesEcological Entomology, EarlyView.
We investigated how temperature and relative humidity influence the parasitic fungus Hesperomyces harmoniae on the invasive ladybird Harmonia axyridis under controlled laboratory conditions. Abiotic factors significantly affect parasitism: High relative humidity increased parasite prevalence, development rate, and load, while both low and high ...

Ecological and Evolutionary Predictors of Dorsal Colouration in Lagomorphs

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim To evaluate the extent to which dorsal body colouration in lagomorphs follows ecogeographical patterns, particularly Gloger's rule, by assessing the relative influence of climate, forest vertical structure, and phylogenetic relatedness on eumelanin‐ and pheomelanin‐based pigmentation. Location Global. Time Period Contemporary.
