Marine Diversity

Relatively very little is known about pygmy seahorses, and even basic information regarding their distributions is largely inconsistent and often based on unofficial reports. However, monitoring marine diversity, particularly for small and cryptic species, such as pygmy seahorses, can be both costly and time consuming. In such cases, the use of citizen science can offer an effective tool for addressing knowledge gaps caused by a lack of biodiversity-related data. Scuba divers and underwater photographers were engaged through social media in order to investigate pygmy seahorse diversity in Taiwan. Using this approach five species of pygmy seahorses were identified, including two new records for Taiwan: Hippocampus denise and Hippocampus japapigu, the latter of which is the first record of the species from outside of Japan. These new records mark Taiwan as one of the world’s pygmy seahorse diversity hotspots, matching that of Japan and Indonesia, as well as demonstrating the value of citizen science for marine biodiversity monitoring, particularly for small cryptic species.

Saint Martin's Island is the only island in Bangladesh where coral communities are found. An expedition on marine biodiversity monitoring of Saint Martin’s Island through underwater visual census method was carried out from December 2017 to March 2018. In this study, a total of 25 scleractinian coral species of 8 families and 14 genera were identified, of which 12 species, Dipsastraea lizardensis, Dipsastraea maritima, Dipsastraea veroni, Favites acuticollis, Favites melicerum, Favites pentagona, Goniastrea stelligera, Goniopora albiconus, Goniopora norfolkensis, Pavona clavus, Plesiastrea versipora, and Psammocora exesa were recorded for the first time in Bangladeshi marine water. These new records exemplify gaps in sampling and recording of coral species in Bangladesh, and suggest the need of extensive research on coral ecosystem in the country. Assessment of different valid reports and publications including the present study revealed that a total of 98 species of hard corals of 18 families and 37 genera have been reported until now in Saint Martin’s Island as well as Bangladesh.

Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.

The Neotropical species of the genus Manota Williston are studied, based on material of 146 specimens from French Guiana, Ecuador, Nicaragua, Dominica and the Dominican Republic. Four new species are described, viz. M. corniculata sp. n. (French Guiana), M. pseudocavata sp. n. (French Guiana), M. truuverki sp. n. (French Guiana) and M. vladi sp. n. (Dominican Republic). Manota defecta Williston, 1896, the type species of the genus, is listed from Dominica, representing the first record since its description more than a century ago from a Southern Caribbean Island, St. Vincent. New records of 13 additional species are provided: M. acutistylus Jaschhof & Hippa, 2005 (Dominica), M. aligera Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. digitata Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. iota Hippa & Kurina, 2013 (French Guiana), M. micula Hippa & Kurina, 2013 (French Guiana), M. nordestina Kurina, Hippa & Amorim, 2018 (French Guiana), M. parva Jaschhof & Hippa, 2005 (Nicaragua), M. pauloides Hippa, Kurina & Sääksjärvi, 2017 (Ecuador), M. perplexa Kurina, Hippa & Amorim, 2017 (Nicaragua), M. rotundistylus Jaschhof & Hippa, 2005 (Ecuador), M. serrulata Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. spinosa Jaschhof & Hippa, 2005 (French Guiana), M. subaristata Kurina, Hippa & Amorim, 2017 (Ecuador). The number of Neotropical Manota species has risen to 96.

This study constitutes the most comprehensive effort ever done to assess the faunal diversity of the Macrobrachium genus within two ecoregions that encompass part of the northeastern Brazil: the Northeastern Caatinga & Coastal Drainages, and the São Francisco (Lower-middle and Lower portions). Through sampling in several of their hydrographic basins, bibliographic research, and consulting scientific collections, our results reveal the occurrence of five species along these ecoregions: Macrobrachium acanthurus, M. amazonicum, M. carcinus, M. jelskii and M. olfersii. We also provide the first record of these species for several river basins in both ecoregions. Additionally, we confirm the occurrence of M. carcinus from Rio Grande do Norte State and provide updated distribution maps for each species in the studied area. This carcinofauna survey may form the basis for future evaluations of eventual anthropic impacts on biological diversity resulting from projects being implemented in these regions, which involve the São Francisco interbasin water transfer.

<p>Late Paleozoic deglaciation is the Earth’s first icehouse-to-greenhouse transition in a vegetated world, but the climatic and biological responses to this transition have not yet been fully addressed. We conducted cyclostratigraphic analysis on the magnetic susceptibility from a deep marine carbonate succession in South China, to reconstruct the astrochronology of the late Early Permian, and to decipher evolutionary responses to astronomically forced climate changes in a marine diversity time series. Our results indicates that the minima of ~1.8 m.y. short orbital eccentricity amplitude modulation cycles led to seasonally stable precipitation patterns and a constant input of nutrients, which spurred marine biodiversity during this deglaciation. Synchronizing global biotic and abiotic records reveals that peaks of marine biodiversity occurred during nodes of ~1.3 m.y. obliquity amplitude modulation cycles, when ice sheet expansion triggered enhanced precipitation and organic carbon burial during icehouse conditions (290−285.1 Ma). Starting at 285.1 Ma, the insolation-biodiversity relationship began to change, paced by glacial termination and tropical aridification. With the transition to greenhouse conditions (~279.1−272 Ma), obliquity nodes became associated instead with terrestrial aridity and marine anoxia, and suppression of marine speciation. Our results bring into focus a pattern of shifting dynamics involving Earth’s astronomical parameters, climate change and marine biodiversity for icehouse and greenhouse worlds in the late Paleozoic Era.</p>

Ostracod Species

Between 2015 and 2017, 58 ostracod taxa were collected at 30 locations in 111 samples from the hyporheic zone of surface streams in Texas, U.S.A. Six new species (Bradleycypris foresteri n. sp., Bradleystrandesia macula n. sp., Pseudocandona lordi n. sp., Indocandona rusti n. sp., Stenocypris sancari n. sp., Cyclocypris dalyana n. sp.) are described based on carapace and soft body parts. Additionally, 17 species and two genera (Vestalenula and Indocandona) are presented as new records for Texas, and Indocandona rusti n. sp. is the first record of the genus outside India. Taxonomic positions of the new species are discussed along with ecological information. One-hundred and six nonmarine ostracod species are now reported from Texas. However, ongoing studies suggest that actual species richness is much higher.
