Coexistence often involves niche differentiation either as the result of environmental divergence, or in response to competition. Disentangling causes such divergence requires that variation across space is taken into account, which rarely done empirical studies. We address role versus competition coexistence between two rodent species: Rhabdomys bechuanae (bechuanae) and dilectus (dilectus) comparing their habitat preference home range (HR) size areas with similar climates, where...
Species invasions are a global scourge. Nonetheless, they provide the appropriate evolutionary setting to rigorously test role that interspecific competition plays in species evolution. The process of ecological character displacement, which diverge sympatry minimize resource use overlap, is one example. Here, we examine whether displacement occurs as result invasion and, if so, morphological adaptations subsequently evolve. We studied lizard Anolis cristatellus Dominica, where native...
During the last two decades, genotyping of African rodents has revealed important hidden diversity within morphologically cryptic genera, such as Rhabdomys. Although distribution Rhabdomys is known historically, its been only recently, and information about range constituent taxa limited. The present study contributes to clarifying taxa, primarily in southern Africa, identifies gaps our knowledge, by: 1) compiling available on distribution; 2) significantly increasing number geo-localised...
Abstract A recent study showed that hurricanes can act as selective agents affecting the phenotype of anole populations subjected to these extreme climatic events. Specifically, Anolis lizards survived were shown have larger toepads than those did not. To test whether more generally impact lizards, we collected data on toepad size, lamella number and grip strength for two species island Dominica in 2018 compared them with 2016 before Hurricane Maria devastated island. Our results show both...
Invasive species are a global threat to biodiversity. Cases where the invasion has been tracked since its beginning rare, however, such that first interactions between invasive and native remain poorly understood. Communication behavior is an integral part of identity subject selection. Consequently, resource use direct interference competition may drive evolution. Here, we tested role recently introduced lizard Anolis cristatellus oculatus on variation in communication Calibishie...
Species invasions may drive native species to extinction. Yet, the role of competition with a closely related in establishment success an invasive remains poorly understood. Indeed, opportunities study native–invasive action are rare, especially at very first stages invasion. We studied recent invasion lizard Anolis cristatellus Dominica, where oculatus occurs. examined difference bite force as proxy for fighting ability and access food resources, its effect on species. measured head...
Invasive species are a world-wide threat to biodiversity. Yet, our understanding of biological invasions remains incomplete, partly due the difficulty tracking and studying behavioural interactions in recently created interactions. We tested whether between introduced invasive lizard Anolis cristatellus native oculatus Dominica have led changes recognition aggressive behaviour species. The use realistic robots allowed us test response 131 A. males towards relevant controlled conspecific...
Nest‐site selection is an important component of species socio‐ecology, being a crucial factor in establishment group living. Consequently, nest‐site characteristics together with space‐use proxies may reveal the social organization species, which critical when direct observation interactions hindered nature. Importantly, choice expected to be under strong selective pressures and object intra‐ interspecific competition. Although bulk research on sociality focuses its ecological drivers, our...
This study reports a high rate of ventro–ventral (VV) copulation in 2 species the African four-striped mouse—Rhabdomys—and explores its causes. VV postures were observed 67% encounters with mating attempts, both and during intra- interspecific trials, although discrimination between occurred (i.e., duration sexual behavior or social investigation varied interspecies encounters). Striped mice displayed more investigatory coitus than without attempts only dorso–ventral postures. Furthermore,...
