Are traits that experience reinforcement also under sexual selection? [PDF]

open access: yes, 2007
Where closely related species occur in sympatry, reinforcement may result in the evolution of traits involved in species recognition that are at the same time used for within-species mate choice.

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Variation in cuticular hydrocarbons among strains of the Anopheles gambiae sensu stricto by analysis of cuticular hydrocarbons using gas liquid chromatography of larvae

open access: yesMemorias do Instituto Oswaldo Cruz, 2000
Cuticular hydrocarbons of larvae of individual strains of the Anopheles gambiae sensu stricto were investigated using gas liquid chromatography. Biomedical discriminant analysis involving multivariate statistics suggests that there was clear hydrocarbon ...

Cuticular hydrocarbons in social insects

open access: yes, 2021
All insects are covered by an epicuticular lipid layer comprising of long hydrocarbon chains generally termed cuticular hydrocarbons (CHCs)(2). In social insects, CHCs play multiple roles: they primarily serve structural and anti-desiccation functions, but they are also involved in various forms of signalling.

Tapinarof as a Therapeutic Aryl Hydrocarbon Receptor‐Modulating Agent in the Treatment of Atopic Dermatitis

open access: yesThe Journal of Dermatology, EarlyView.
ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory dermatitis underpinned by Type 2 inflammation driven by cytokines such as IL‐4 and IL‐13. It is characterized by skin barrier dysfunction, Th2 immune deviation, and pruritus. While biologics and oral Janus kinase (JAK) inhibitors demonstrate high therapeutic efficacy by targeting cytokines that ...

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

open access: yesJournal of Animal Ecology, EarlyView.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Cuticular wax modification by Epichloë endophyte in Achnatherum inebrians under Blumeria graminis infection

open access: yesGrass Research
Achnatherum inebrians is a perennial plant belonging to the Poaceae, subfamily Pooideae, which often forms a symbiosis with fungal endophytes of the genus Epichloë. In this study, E. gansuensis-infected (E+) and E. gansuensis-free (E−) A.

Sexual Communication in the Drosophila Genus

open access: yesInsects, 2014
In insects, sexual behavior depends on chemical and non-chemical cues that might play an important role in sexual isolation. In this review, we present current knowledge about sexual behavior in the Drosophila genus.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
