Urbanization increases fluctuating asymmetry and affects behavioral traits of a common grasshopper

“…Growing literature indicates that females and males differ in the mean levels of behavioral expression (Schuett et al, 2010) and repeatability of behavioral traits (Bell et al, 2009). Although a meta‐analysis has already shown that personality and traits are not sex‐dependent in most of the animals (Harrison et al, 2021), there may be sex‐specific differences with respect to certain traits in some species (e.g., sex‐specific dispersal, Han & Dingemanse, 2017; Li & Kokko, 2019; Trochet et al, 2016; exploration and aggression, Kralj‐Fišer et al, 2019, 2021; activity and risk‐taking behavior, Mezőfi et al, 2022), leading to the evolution of sex‐specific genetic architecture behind such traits (Lande, 1980). In addition, responses to environmental stress may be sex‐dependent.…”

Sex-specific life-history strategies among immature jumping spiders: Differences in body parameters and behavior

“…Among spiders, sexual dimorphism is very common in several features such as morphology, behavior, and life history. Sex-specific morphological and behavioral traits can be genetically determined ( Kralj-Fišer et al 2019 , 2021 ; Chang et al 2020 ; Cordellier et al 2020 ) and generate specific consequences for life history. For example, spiders usually practice protandry, that is, a male matures earlier and has a shorter lifespan than a female ( Klein 1988 ; Uhl et al 2004 ; Foelix 2011 ; Kralj-Fišer et al 2014 ).…”
