Article Reference Shell anatomy of the African Paleocene bothremydid turtle Taphrosphys congolensis and systematic implications within Taphrosphyini
The bothremydid pleurodiran turtle Taphrosphys congolensis is a member of Taphrosphyina from the Paleocene of the Cabinda Province (Congo Basin, Angola). Very few specimens corresponding to elements of its shell have been so far figured. Abundant unpublished remains are analyzed in this paper. As a consequence, several regions of the shell are figured and characterized here for the first time, and intraspecific variability is recognized for several characters. Previous authors proposed some putative differences between the shells of Taphrosphys congolensis and the North American Paleocene Taphrosphys sulcatus. The increase in the knowledge about the shell of this African form allows us to refute most of them, the shell of both forms being recognized as more similar than previously identified. Thus, the identification of the genus Taphrosphys as restricted to three forms (i.e. the skull taxon Taphrosphys ippolitoi, and the skull and shell forms T. congolensis and T. sulcatus) is supported, and the record unquestionably attributable to this genus is modified from the Upper Cretaceous–Eocene lapse of time to the Paleocene exclusively.

Article Reference Short-term effects of fishery exclusion in offshore wind farms on macrofaunal communities in the Belgian part of the North Sea
With the wide scale construction of offshore wind farms (OWFs) throughout the entire North Sea, largeareas are permanently being closed to beam trawl fisheries. Beam trawling has affected macrobenthicassemblages for centuries, especially the fragile and long-lived species. Due to the prohibition of beantrawling in many OWFs, opportunities are being provided to investigate the potential recovery of vulnera-ble species and the creation of de-facto Marine Protected Areas (MPAs). The soft-substrate macrobenthiccommunity was investigated from 2008 to 2012, before and after the construction of an OWF in theBelgian part of the North Sea, situated on the Bligh Bank. The fishery enclosed area (±21 km2) withinthe OWF (No Fishery area) was compared with a surrounding control area (±30 km2) where regularfishing activities were registered through vessel monitoring system (VMS) data throughout the period2010–2011. Three years after the exclusion of beam trawl fisheries, subtle changes within the macroben-thic community were observed in the No Fishery area. The benthic mysid shrimp Gastrosaccus spinifer(30 ± 15 ind m−2), tube-building polychaetes Terebellidae sp. (196 ± 151 ind m−2) and the echinodermEchinocyamus pusillus (73 ± 71 ind m−2), sensitive to trawling activities, showed increased abundanceswithin the No Fishery area. With an expansion of the wind farm concession area to 238 km2in the future,the likely increase of dense Terebellidae patches (e.g., Lanice conchilega reefs) within the No Fishery areacould create an ecological important large-scale refugium for higher trophic levels. This study creates abaseline for the evaluation of long-term changes due to the fishing impacts and effects related to the pres-ence of OWFs and highlights the importance of executing long-term monitoring programs in combinationwith targeted research.

Article Reference Significant loss of mitochondrial diversity within the last century due to extinction of peripheral populations in eastern gorillas
Species and populations are disappearing at an alarming rate as a direct result of human activities. Loss of genetic diversity associated with population decline directly impacts species’ long-term survival. Therefore, preserving genetic diversity is of considerable conservation importance. However, to assist in conservation efforts, it is important to understand how genetic diversity is spatially distributed and how it changes due to anthropogenic pressures. In this study, we use historical museum and modern faecal samples of two critically endangered eastern gorilla taxa, Grauer’s (Gorilla beringei graueri) and mountain gorillas (Gorilla beringei beringei), to directly infer temporal changes in genetic diversity within the last century. Using over 100 complete mitochondrial genomes, we observe a significant decline in haplotype and nucleotide diversity in Grauer’s gorillas. By including historical samples from now extinct populations we show that this decline can be attributed to the loss of peripheral populations rather than a decrease in genetic diversity within the core range of the species. By directly quantifying genetic changes in the recent past, our study shows that human activities have severely impacted eastern gorilla genetic diversity within only four to five generations. This rapid loss calls for dedicated conservation actions, which should include preservation of the remaining peripheral populations.
