We examine the dimensions and nature of the Earth’s terrestrial biodiversity and review the scientific facts concerning the rate of loss of biodiversity and the drivers of this loss. The estimate for the total number of species of eukaryotic organisms possible lies in the 5–15 million range, with a best guess of 7 million. Species diversity is unevenly distributed; the highest concentrations are in tropical ecosystems. Endemisms are concentrated in a few hotspots, which are in turn seriously threatened by habitat destruction—the most prominent driver of biodiversity loss. For the past 300 years, recorded extinctions for a few groups of organisms reveal rates of extinction at least several hundred times the rate expected on the basis of the geological record. The loss of biodiversity is the only truly irreversible global environmental change the Earth faces today. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

This meeting brought together over 80 scientists from 19 countries on four continents (Europe, and Co-chairs . 34 North America, South America, and Australia). Representation from the United States was rather low, Parting Shot . 35 but that was expected, as several other meetings on freshwater molluscs were held in the USA earlier in the year. Ellipsaria Vol. 17 - No. 4 December 2015 The First International Meeting on Biology and Conservation of Freshwater Bivalves was held in Bragança, Portugal, in 2012. That meeting was organized by Manuel Lopes-Lima and his colleagues from several academic institutions in Portugal. In addition to being a research scientist with the University of Porto, Portugal, Manuel is the IUCN Coordinator of the Red List Authority on Freshwater Bivalves. The goal of the first meeting was to create a network of international experts in biology and conservation of freshwater bivalves to develop collaborative projects and global directives for their protection and conservation. The Bragança meeting was very productive in uniting freshwater mussel biologists from European countries with their colleagues in North and South America. The meeting format did not include concurrent sessions, which allowed everyone to attend to every talk and all of the plenary talks by leading scientists. -
Freshwater Snail Diversity in Mae Lao Agricultural Basin (Chiang Rai, Thailand) with a Focus on Larval Trematode Infections
ISSN (Print) 0023-4001 ISSN (Online) 1738-0006 Korean J Parasitol Vol. 56, No. 3: 247-257, June 2018 ▣ ORIGINAL ARTICLE https://doi.org/10.3347/kjp.2018.56.3.247 Freshwater Snail Diversity in Mae Lao Agricultural Basin (Chiang Rai, Thailand) with a Focus on Larval Trematode Infections Kittichai Chantima*, Krittawit Suk-ueng, Mintra Kampan Energy and Environment Program, Faculty of Science and Technology, Chiang Rai Rajabhat University, Chiang Rai 57100, Thailand Abstract: The aim of this study was to conduct a freshwater snail survey in Mae Lao agricultural basin to assess the di- versity with a focus on habitat types and their larval trematode infections. Snails were collected and examined in 14 sites of Mae Lao agricultural basin from August 2016 to October 2017. A total of 1,688 snail individuals were collected and classified into 7 families, 8 genera, and 12 species. Snail diversity and habitat types were higher in rice paddies than irri- gation canals and streams. The most abundant species was Bithynia siamensis siamensis, representing 54.6% of the sample. Three species of snails act as first intermediate host were found with cercarial infections. They were Filopaludina sumatrensis polygramma, B. s. siamensis, and Melanoides tuberculata. The cercariae were categorized into 7 types; echi- nostome, monostome, gymnocephalous, virgulate, parapleurolophocercous, pleurolophocercous and megalurous cer- cariae. Parapleurolophocercous cercariae constituted the most common type of cercariae recovered, contributing 41.2% of all infections in snails. Echinostome metacercariae infections were found in 6 snail species with 7.6% prevalence. In addition, the metacercaria of avian trematode, Thapariella sp. were found in Filopaludina spp. -

The Morphology and Ontogenetic of Tarebia Granifera (Lamarck, 1822) from Indonesia (Gastropoda: Cerithioidea: Thiaridae) Abstr

Raya Jakarta-Bogor Km 46, Cibinong, Bogor 16911, Indonesia *Corresponding author: [email protected] Received: 14 November 2016; Accepted: 2 November 2017 ABSTRACT The freshwater gastropod Tarebia H. Adams & A. Adams, 1854, are found in rivers, lakes, and other limnetic habitats. In Indonesia, Tarebia granifera (Lamarck, 1822) is the only species within the genus that has a wide distribution. The systematics and identity of this species are still doubtful due to high variation in shell morphology, especially shell height and ornamentation or sculpture of shell. To determine the identity of T. granifera from Lombok, Banten, and Maros, ontogenetic studies have been conducted. The results showed that T. granifera from Lombok produce the highest number of embryonic shells. The number of progeny in the brood pouch from a single individual of T. granifera can vary between 9 to 203 embryonic shells which are found in various stages of 0.22 mm to about 5 mm in size inside the brood pouch. Key words: embryonic shell, ontogeny, subhaemocoelic brood pouch, Tarebia granifera, Thiaridae INTRODUCTION Tarebia granifera (Lamarck, 1822) (Thiaridae) occurs in freshwater bodies, in lotic as well as lentic habitats. This species belongs to benthic fauna and lives attached to different kinds of substrate or on the banks of aquatic habitats. -
Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia

The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachy- rotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two fami- lies, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be character- ised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few species in the Pebas fauna include important ecological groups, such as indicators of marine infl uence (e.g., Nassariidae, one species), terrestrial settings (e.g., Acavidae, one species) and stagnant to marginally agitated freshwaters (e.g., Planorbidae, four species).
