Mediterranean climate regions are globally recognized as hotspots of endemism in fishes;
however, these unique assemblages are increasingly threatened by human mediated …

Headwater streams in Afromontane ecoregions harbour locally adapted aquatic
communities. However, across many regions in Africa, these ecosystems and their unique …

African sharptooth catfish Clarias gariepinus has been spread globally and is proven to be
invasive with demonstrable impacts on a variety of biota in recipient ecosystems. There are …

Despite supporting a disproportionately large fraction of the global biodiversity, freshwater
ecosystems are ranked as the most highly threatened habitats ahead of both terrestrial and …

Animals exhibit diel periodicity in their activity in part to meet energy requirements whilst
evading predation. A competing hypothesis suggests that partitioning of diel activities is less …

To test ecological niche theory, this study investigated the spatial patterns and the
environmental niches of native and non‐native fishes within the invaded Great Fish River …

We examined innate responses to conspecific and heterospecific alarm cues in a small
cyprinid minnow, the Eastern Cape redfin Pseudobarbus afer. We found that redfins respond …

The availability of appropriate refugia may ameliorate some impacts of habitat degradation
and can aid in the conservation of target species. In addition to natural refugia, the provision …

In temperate headwater streams, intra-annual variation in energy input is critical in
influencing aquatic food webs. We used stable isotope analysis to explore how seasonal …

The availability of appropriate refugia may ameliorate some impacts of habitat degradation
and can aid in the conservation of target species. In addition to natural refugia, the provision …
