Greater reproductive investment, but shorter lifespan, in agrosystem than in natural-habitat toads

Abstract: Global amphibian decline is due to several factors: habitat loss, anthropization, pollution, emerging diseases, and global warming. Amphibians, with complex life cycles, are particularly susceptible to habitat alterations, and their survival may be impaired in anthropized habitats. Increased mortality is a well-known consequence of anthropization. Life-history theory predicts higher reproductive investment when mortality is increased. In this work, we compared age, body size, and different indicators of reprod… Show more

“…Accordingly, Hyla arborea male frogs showed no negative effect of testosterone injection on swelling response to PHA (Desprat et al, 2015). Indeed, immune responsiveness to PHA has often been found similar in male and female anurans (Zhang et al, 2017), also in this species (Zamora-Camacho & Comas, 2017).…”

“…Conversely, an immune challenge can trigger terminal investment (Bonneaud et al, 2004; Nielsen & Hokman, 2012), suggesting complex relationships between immune system and reproduction in the context of ageing. Indeed, reproduction and immune activity are under a trade-off in great tit ( Parus major ) females (Ots & Horak, 1996), as could also be happening in this system, where some indicators of reproductive investment are higher in older individuals in E. calamita toads (Zamora-Camacho & Comas, 2017).…”
