Deep reefs are not refugium for shallow-water fish communities in the southwestern Atlantic
<p>1. The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are amongst the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the DRRH is valid at the community level, the diversity of species, functions and lineages of fish communities of shallow reefs should be encapsulated in deep reefs.</p> <p>2. We tested the DRRH by assessing the taxonomic, functional and phylogenetic diversity of 22 Brazilian fish communities between 2 and 62m depth. We partitioned the gamma diversity of shallow (<30m) and deep reefs (>30m) into independent alpha and beta components, accounted for species' abundance, and assessed if beta patterns were mostly driven by spatial turnover or nestedness.</p> <p>3. We recorded 3821 fishes belonging to 85 species and 36 families. Contrary to DRRH expectations, only 48% of the species occurred in both shallow and deep reefs. Alpha diversity of rare species was higher in deep reefs as expected, but alpha diversity of typical and dominant species did not vary with depth. Alpha functional diversity was higher in deep reefs only for rare and typical species, but not for dominant species. Alpha phylogenetic diversity was consistently higher in deep reefs, supporting DRRH expectations.</p> <p>4. Profiles of taxonomic, functional, and phylogenetic beta diversity indicated that deep reefs were not more heterogeneous than shallow reefs, contradicting expectations of biotic homogenization near sea surface. Furthermore, pairwise beta diversity analyses revealed that the patterns were mostly driven by spatial turnover rather than nestedness at any depth.</p> <p>5<i>. </i>Conclusions: Although some results support the DRRH, most indicate that the shallow-water reef fish diversity are not fully encapsulated in deep reefs. Every reef contributes significantly to the regional diversity and must be managed and protected accordingly.</p>

Data from: A phylogeographical survey of a highly dispersive spider reveals eastern Asia as a major glacial refugium for Palaearctic fauna
Aim: The phylogeographical history of wide-ranging Palaearctic species is not well understood. Here, we present a range-wide phylogeographical study of the wasp spider, Argiope bruennichi (Scopoli, 1772), a highly dispersive and widely distributed Palaearctic species. We aim to identify glacial refugia and patterns of interglacial gene flow across the Palaearctic. Location: Palaearctic region, including the Azores, Madeira, Europe, North Africa and Asia. Methods: We conduct a range-wide phylogeographical survey. Our study is based on nuclear and mitochondrial DNA markers, as well as morphological characters. We use species distribution models to predict the species' current range as well as its historical distribution during and shortly after the Last Glacial Maximum (LGM). Results: All analysed genetic markers and morphological characters support the divergence of a lineage in eastern Asia from the remainder of the Palaearctic. Within the Western Palaearctic, a less pronounced divergence into an Azorean and a European clade is found. Species distribution models predict a pronounced loss of suitable habitat for Western Palaearctic lineages during the LGM, whereas the range of East Asian populations remained largely unaffected. Main conclusions: Our results highlight the existence of non-European glacial refugia for Palaearctic species, particularly in East Asia. The current genetic structure is best explained by the recent recolonization of the Western Palaearctic from eastern Asia, or repeated interglacial contact of populations.
