The taxonomic status of Farlowella colombiensis Retzer & Page 1997 with comments on species of the F. acus species group (Loricariidae: Loricariinae). [PDF]
Abstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such

Mitigating the effects of climate change on the nests of sea turtles with artificial irrigation. [PDF]
Abstract For sea turtles, like many oviparous species, increasing temperatures during development threaten to increase embryonic mortality, alter offspring quality, and potentially create suboptimal primary sex ratios. Various methods are being implemented to mitigate the effects of climate change on reproductive success, but these methods, such as ...

The interplay between virus infection and water-related stress is mediated by the plant metabolism of ascorbic acid. [PDF]
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection
