In 1962, 1964 and 1966 the author collected four species of marine triclads, viz. Procerodes littoralis (Ström), P. ireneae sp.nov., P. lobata (O. Schmidt) and Uteriporus vulgaris Bergendal in the Plymouth neighbourhood. Each species is fully described. Attention has been given not only to internal characters, as the structure of the genital apparatus, but also to external features such as the shape of the head and the pattern of pigmentation, because these external characters are sufficient for the identification of the species. Further, the geographical distribution and ecological data have been recorded for each species.

<p>The integrated European Long-Term Ecosystem, critical zone and socio-ecological Research Infrastructure (eLTER RI) was accepted onto the ESFRI roadmap in 2018. While several existing thematic environmental RIs in Europe focus on impacts of climate change and/or other elements of environmental change, eLTER RI will be the only research infrastructure embracing holistically the integrated impacts of such stressors on a wide variety of European benchmark ecosystems (major geo-eco-sociological systems across the continent’s ecoclimatological zones and Earth’s critical zone). In the beginning of 2020 eLTER RI entered the preparatory phase aiming at the development of the legal, financial and technical maturity required for an ESFRI Research Infrastructure.</p><p>The core of the eLTER RI will be ca. 200 selected sites covering all biogeographical zones in Europe, where biological, biogeochemical, hydrological and socio-ecological data will be collected - according to common standards - and analyzed. The European landscape of LTER sites and national networks has mainly been developed in a bottom-up manner. The sites have mostly been established for different monitoring and research purposes and are heterogeneous in terms of investigated ecosystem types, scales of investigation, complexity and instrumentation. Consequently, the transformation of the selected elements of the eLTER RI into a harmonized, high-performance, complementary and interoperable infrastructure is one of the key challenges of eLTER. Achieving the best possible representativity is on the major building blocks in eLTER’s design strategy.</p><p>To evaluate the representativity of eLTER a novel statistical approach combining information on biogeographical, ecological and socio-economic gradients with the management-relevant distribution of established sites was developed aiming at  i) identification of areas in Europe that are geographically underrepresented by the existing eLTER RI site network, ii) definition of priority regions for the geographical extension of the eLTER site network and, iii) development of suggestions for conceptual and infrastructural upgrades for existing less developed eLTER sites.</p><p>Reference datasets depicting biogeographical, ecological and socio-economical gradients were used to describe underrepresentation with a summation parameter called Aggregated Representedness. This statistical criterion was then used to classify five types of “priority regions” from very low to very high priority for geographical and/or conceptual extension. In a second step this information on priority regions was refined using additional information describing the geographical distribution based on Euclidean distances between established eLTER sites.  The combination of these two analyses allowed to identify less developed eLTER sites most suitable for conceptual and infrastructural upgrades. Thus, the presented analysis provides important information for the development of the design strategy for eLTER RI on the continental scale.</p><p>Concluding, a novel approach combining information on biogeographical, ecological and socio-economic gradients with the management-relevant information on the geographical distribution of established sites was developed. This tool allows to evaluate the strategies for further extension of established site networks. </p>

We report new records of the White-Tailed Deer (Odocoileus virginianus) in Brazil based on specimens deposited in scientific collections. These new records expand the known geographic distribution of the species in Brazil southwards in the states of Roraima and Amapá, the latter the first record of the species below the equator line in Brazil, and register it for the first time in the state of Amazonas. These records contribute to increase the knowledge of the geographical distribution of O. virginianus in Brazil and highlights the importance of museum collections as a source of biogeographic and ecological data.

The presence of mud lobster mounds is a common natural feature along coastal areas and tidal influence habitats in Sarawak. However, the number of species of mud lobsters that constructed the mounds is yet to be ascertained. This paper reviews historical records and geographical distribution of mud lobster in Sarawak from various forms of literature. The early records of mud lobster were from Buntal in Kuching, and Lingga in Sri Aman back more than 130 years ago. A few other records were reported from the central and northern regions of Sarawak between 1928 and 2019. All these records have identified mud lobster of Sarawak as Thalassina anomala (Herbst, 1804). Our present study at two sites in Buntal area with a careful examination of morphological characters of fresh specimens has confirmed the taxonomy of the species and its existence in the area. Some ecological characteristics of the mud lobster, such as size variation, population density, and mound characteristics, are also discussed. The present study also found that construction of massive mounds by mud lobster has posed a conflict to farmers and coastal communities at Buntal area, who regarded the animal as a pest. On the other hand, research on the potential medicinal value of mud lobster in Sarawak is growing. This implies that accurate taxonomy and comprehensive ecological data of T. anomala are necessary to support best practices of mud lobster pest management and sustainable harvesting of the animal for medicinal purposes, which eventually lead to conserving the animal.

Cladocera (Crustacea: Branchiopoda) biodiversity was examined in sediment assemblages in La Tembladera Lake, on the southern coast of Ecuador. We found remains from 14 Cladocera taxa belonging to three families: Sididae, Daphnidae and Chydoridae. One taxon is planktonic (Ceriodaphniaspp.) and 13 taxa are littoral (Sarsilatonaserricauda,Chydorussp.,Dunheveniasp.,Leberissp.,Alonasp.,Magnospina dentifera,Kurziasp.,Acroperus tupinamba,Camptocercussp.,Oxyurella longicaudis,Leydigiopsissp.,Euryalonasp. andNotoalonacf.sculpta). Descriptions and pictures of the remains were included in this article to help palaeolimnologists identify tropical cladoceran remains in the sediment. These results enlarge the crustacean biodiversity data for dry tropical forests in South America and help to constrain our understanding of their geographical distribution. Further studies should focus on capturing living cladocerans to make identifications at the species level and to help interpret the sedimentary signal using ecological data.

Seven new Brazilian species of Exogonia Melichar are described from Mato Grosso, Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, and Santa Catarina states. The other four known species of the genus, E. assimilis (Signoret), E. hyalinosparsa (Melichar), E. leucampix (Signoret), and E. semivitta (Walker), are redescribed. An identification key with male and female characters and maps with the geographical distribution of the species are given. Taxonomic notes comparing the species are also provided. This genus is apparently closely related to Hanshumba Young, specially due to similarities in the male genital apparatus.
