The ecological health of Lake Victoria (Kenya) in the face of growing cage aquaculture

open access: yesConservation Science and Practice, 2022
The rapid growth of cage aquaculture of introduced Nile tilapia (Oreochromis niloticus) in Lake Victoria has raised urgent environmental concerns. This study aims to compare local environmental conditions, fish species abundance and diversity between ...

Three in one-multiple faunal elements within an endangered european butterfly species [PDF]

open access: yes, 2015
Ice ages within Europe forced many species to retreat to refugia, of which three major biogeographic basic types can be distinguished: "Mediterranean", "Continental" and "Alpine / Arctic" species.

Biogeographical patterns of the neotropical genus Battus Scopoli 1777 (Lepidoptera Papilionidae) [PDF]

open access: yes, 1993
A phylogenetic approach to the groups of species of the neotropical Troidines currently included in the genus Battus Scopoli 1777 has been conducted. In the light of historical and ecological processes of evolution in the neotropical biota, the cladogram

Effects of Pleistocene climate changes on species ranges and evolutionary processes in the Neotropical Atlantic Forest [PDF]

open access: yes, 2016
The effects of global glaciations on the distribution of organisms is an essential element of many diversification models. However, the empirical evidence supporting this idea is mixed, in particular with respect to explaining tropical forest evolution ...

The fate of endemic insects of the Andean region under the effect of global warming.

open access: yesPLoS ONE, 2017
Three independent but complementary lines of research have provided evidence for the recognition of refugia: paleontology, phylogeography and species distributional modelling (SDM). SDM assesses the ecological requirements of a species based on its known
