Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Drosophila male genitalia rotation depends on permissive remodeling of the posterior abdomen
Developmental Dynamics, EarlyView.Abstract Background One of the most characteristic morphogenetic processes in Drosophila is the 360° rotation of the male pupal genital disc. This movement is driven by the myosin Myo1D, whose expression in the genital disc is controlled by the Hox gene Abdominal‐B (Abd‐B).

Ecography, EarlyView.As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model
Future Postharvest and Food, EarlyView.Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Determination of the Larval Instar Numbers of the Ectropis grisescens at Different Temperatures [PDF]
Chaye kexueEctropis grisescens is one of the most harmful pests in tea plantations, characterized by its frequent annual occurrences and considerable damage. The understanding of the larval instar number remains still elusive.

Life cycle, morphometrics and damage assessment of the Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) on stored groundnut [PDF]
Journal of Agricultural Sciences (Belgrade), 2009 The life cycle of the Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) on stored groundnut was studied under fluctuating laboratory conditions of 25±5°C and 70±5% relative humidity.
