Extensive field work conducted in Paraguay since 1995 allowed us to present the first records for this country of the family Sciuridae (Sciurus urucumus), the genus Bibimys (B. chacoensis), and the species Akodon paranaensis, in addition to the first formal mention of Oxymycterus misionalis, and noteworthy records of Cerradomys maracajuensis, Pseudoryzomys simplex, and Sphiggurus spinosus. These records demonstrate that the mammal fauna of the Paraguayan Oriental Region is more similar in species richness and composition to that of adjacent regions of Argentina and Brazil than previously realized.

The generic classification of millipede associated Heterozerconidae in the Oriental region is revised. The genus Allozercon Vitzthum is re-diagnosed and Asioheterozercon Fain is designated as an subjective junior synonym of Allozercon. Philippinozercon gen. nov., with the type species P. makilingensis sp. nov., is described for all instars. This genus may be endemic for the Philippines, but is quite widespread in that country. All immature instars are described, making this the second species of Heterozerconidae known for all instars. The morphology of the immatures is compared with that of immatures of the temperate species Narceoheterozercon ohioensis and unnamed species from Brazil and Thailand. All immatures were collected from millipede frass and litter, never from millipedes. Adults are associated with millipedes in the family Trigoniulidae (Spirobolida).

Leptomaria antipodensis and Leptomaria hickmanae are described from the Upper Cretaceous [Maastrichtian] Lopez de Bertodano Formation, Seymour Island, and represent the first Mesozoic records of the family Pleurotomariidae from Antarctica. Leptomaria stillwelli, L. seymourensis, Conotomaria sobralensis and C. bayeri, from the Paleocene [Danian], Sobral Formation, Seymour Island, are described as new. Leptomaria larseniana (Wilckens, 1911) new combination, also from the Sobral Formation, is redescribed based on better-preserved material. The limited diversity of the pleurotomariid fauna of Seymour Island is more similar to that of the Late Cretaceous faunas of Australia and New Zealand in terms of the number of genera and species, than to the older, more diverse faunas of South America, southern India, or northwestern Madagascar, supporting the status of the Weddelian Province as a distinct biogeographic unit. The increase in the species richness of this fauna during the Danian may be due to the final fragmentation of Gondwana during this period.

Knowledge about how species richness varies along spatial and environmental gradients is important for the conservation and use of biodiversity. The Ericaceae is a major component of alpine and subalpine vegetation globally. However, little is known about the spatial pattern of species richness and the factors that drive that richness in Ericaceae. We investigated variation in species richness of Ericaceae along an elevational gradient in Yunnan, China, and used a variation partitioning analysis based on redundancy analysis ordination to examine how those changes might be influenced by the mid-domain effect, the species-area relationship, and climatic variables. Species richness varied significantly with elevation, peaking in the upper third of the elevational gradient. Of the factors examined, climate explained a larger proportion of the variance in species richness along the elevational gradient than either land area or geometric constraints. Species richness showed a unimodal relationship with mean annual temperature and mean annual precipitation. The elevational pattern of species richness for Ericaceae was shaped by the combined effects of climate and competition. Our findings contribute to a better understanding of the potential effects of climate change on species richness for Ericaceae.

Abstract: Coastal ecosystems of northeastern Brazil have important biodiversity with regard to marine mollusks, which are insufficiently studied. Here we provide an inventory of mollusks from two sites in the estuary of the Paraíba River. Mollusks were collected in 2014 and 2016 on the coast and sandbanks located on the properties of Treze de Maio and Costinha de Santo Antônio. The malacofaunal survey identified 12 families, 20 genera and 21 species of bivalves, 17 families, 19 genera and 20 species of gastropods and one species of cephalopod. Bivalves of the family Veneridae Rafinesque, 1815 were the most representative, with a total of five species. Gastropods of the family Littorinidae Children, 1834 had the greatest species richness. The most abundant species were: Neritina virginea (Linnaeus, 1758), Brachidontes exustus (Linnaeus, 1758), Crassostrea brasiliana (Lamarck, 1819), Cerithium atratum (Born, 1778), Anomalocardia brasiliana (Gmelin, 1791), Parvanachis obesa (C. B. Adams, 1845), Phrontis polygonata (Lamarck, 1822), Littoraria angulifera (Lamarck, 1822), L. flava (King, 1832), Tagelus plebeius (Lightfoot, 1786), Echinolittorina lineolata (d'Orbigny, 1840) and Iphigenia brasiliensis (Lamarck, 1818). The results show that the study area has considerable species richness of Mollusca, requiring environmental monitoring in the region mainly due to the economic importance of some species to the local population.

Six new amphipod species in the genus Leucothoe from the tropical western Atlantic Ocean are described and illustrated. Extensive field collecting and specialized underwater collecting techniques have documented 43 new invertebrate host records for these new taxa. Four of these new species inhabit interior canals of sponges; Leucothoe barana n.sp., Leucothoe garifunae n.sp., Leucothoe saron n.sp., and Leucothoe ubouhu n.sp. A remarkable new species, Leucothoe flammosa n.sp., nestles in the gills of seven species of bivalve mollusks. A single species, Leucothoe wuriti n.sp., appears restricted to the branchial chamber of two species of solitary ascidians. Detailed illustrations and scanning electron microscopy enables comparison of ultrastructure details. More precise taxonomic character morphologies are also presented thus allowing improved taxonomic precision within the family Leucothoidae.

Chengi a major river of Khagrachari district is getting polluted day by day due to unplanned river management. Both primary and secondary data have been used to conduct this work. Primary data have been collected through extensive field work, questionnaire and sample collection. Water samples have been collected from three sampling station, namely Ganjapara, Chengi Bridge and Rubber factory sites. Water temperature is higher at different sampling stations in the study site than Bangladesh standards (25°C) due to the direct hit of the sun. The maximum DO value is 5.8 mg/l at the sampling station one and the minimum is 5.3 mg/l at station three. So, it concluded that the DO value of the Chengi river is comparatively lower than the Bangladesh Standards. The water Temperature and pH is higher than the Bangladesh standards and the value of other parameters are very lower than the Bangladesh standards. In fish diversity, 10 families belonging to 6 orders were recorded and identified by the fin formula. The order Cypriniformes occupied 40%, the order Perciformes which occupies 25% and the order Beloniformes, Siluriformes, Cyprinodontiformes occupied 10% and Mollusks and other invertebrates occupied 25%, respectively in all cases. This work provides a complete picture of the water quality and also the fish diversity of the Chengi River. It will be helpful for water resource management and planning. Bangladesh J.
