Phenotypic senescence and multilevel variation in different body sizes in a natural insect population

Kata Pásztor, Ádám Kőrösi, Ádám Gór & János Kis
Senescence seems to be universal in living organisms and plays a major role in life-history strategies. Phenotypic senescence, decline of body condition and/or performance with age, is a largely understudied component of senescence in natural insect populations, although it would be important to understand how and why insects age under natural conditions. We aimed a) to investigate how body mass and thorax width change with age in a natural population of the univoltine Clouded Apollo...

Dietary flexibility promotes range expansion: the case of golden jackals in Eurasia

József Lanszki, Matthew W. Hayward, Nathan Ranc & Andrzej Zalewski
Aim: Exploring the drivers of the successful ongoing expansion of the golden jackal across Europe is essential to understand the species’ trophic ecology. We analysed which climatic and environmental factors affected the dietary composition of golden jackals and compared these drivers in the species’ historic and recently colonised distribution ranges. Location: Eurasia. Taxon: golden jackal (Canis aureus). Methods: Using 40 published data sets, we modelled the diet composition using 13 food categories based on the...

Data from: White plumage color as an honest indicator: feather macrostructure links reflectance with reproductive effort and success

Miklós Laczi, Mónika Jablonszky, Gábor Markó, Gergely Nagy, Gyula Szabó, Sándor Zsebők, János Török & Gergely Hegyi
The structural condition of feathers may generally have a decisive role in shaping the color properties of the plumage. However, the information content of structurally mediated color differences is poorly known. This makes it particularly hard to determine the meaning of color variation in pigment-free white plumage patches. The white wing patch of the collared flycatcher (Ficedula albicollis) is an important sexual trait, and changes in its reflectance are partly due to macrostructural condition. We...
