Abstract Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals produce any offspring (fertility), or number produced fertile (fecundity). This has important ecological consequences, because reproduction is ultimate measure population fitness: a reduction in reproductive output lowers growth rate and increases extinction risk. Despite this importance, there have been no large‐scale summaries evidence for effect temperature on...
The intensity and direction of sexual selection are intricately linked to the social ecological context. Both operational sex ratios (OSRs) population densities can affect ability males monopolize resources mates, thus form on them. Here, we studied how mating system promiscuous strongly sexually dimorphic fruit fly Drosophila prolongata responds changes in OSR density. We recorded groups flies over five days quantified territory occupancy, success (MS) competitive fertilization success....
Abstract Sexual selection promotes traits that enhance mating or fertilization success, but these can be very costly under harsh environmental conditions. The extent to which differential investment in varying intensities of sexual is related their susceptibility stress remains unclear. This study explored how experimental evolution different operational sex ratios (OSRs) shapes and reproductive success male Drosophila prolongata, developmental and/or adult heat affect the expression traits....
Nutrient limitation during development can restrict the ability of adults to invest in costly fitness traits, and genotypes vary their sensitivity developmental nutrition. However, little is known about how genotype nutrition affect male maintain ejaculate allocation achieve fertilization across successive matings. Using 17 isogenic lines Drosophila melanogaster, we investigated variation affects males' abilities mate, transfer sperm, sire offspring when presented with virgin females. We...

Frequent and extreme temperatures associated with climate change pose a major threat to biodiversity, particularly for organisms whose metabolism is strictly linked ambient temperatures. Many studies have explored thermal effects on survival, but heat-induced fertility loss emerging as greater population persistence. However, while evidence accumulating that both juvenile adult stages heat exposure can impair in their own ways, much less known about the immediate longer-term fitness...
Rapid exaggeration of host and pathogen traits via arms race dynamics is one possible outcome host-pathogen coevolution. However, the exaggerated are expected to incur costs in terms resource investment other life-history traits. The current study investigated associated with evolved a coevolution system. We used Drosophila melanogaster (host)-Pseudomonas entomophila (pathogen) system experimentally derive two selection regimes, where both coevolved, other, only against non-evolving...
Post-copulatory sexual selection (PSS) is an important selective force that determines fitness in polyandrous species. PSS can be intense some cases and drive the evolution of remarkable ejaculate properties. In males, investment plays role outcome PSS. Thus, males are expected to adaptively tailor their according perceived competition vicinity. Plastic responses variation intrasexual disparate widespread males. We investigated plasticity reproductive traits using Drosophila melanogaster...
Abstract Sexual selection is a major force influencing the evolution of sexually reproducing species. Environmental factors such as larval density can manipulate adult condition and influence direction strength sexual selection. While most studies on crowding are either correlational or single‐generation manipulations, it unclear how under chronic affects To answer this, we measured male female Drosophila melanogaster that had evolved for over 250 generations in laboratory, along with their...
Background:: Musculoskeletal disorders (MSDs) are a group of non-fatal injuries that can occur as result various repetitive workplace activities, mainly in unorganized sectors. Workers who engage highly activities involving constant hand effort, localized mechanical pressure, and vibration more prone to developing these disorders. Objective:: The objective this research was determine the prevalence MSDs among workers sectors India perform hand-intensive occupations. Method:: A...
