Macroinvertebrate Fauna

This study investigates the marine macroinvertebrate fauna of rhodolith beds (non-geniculated red corallinaceaous algae) in northeast Brazilian. A total of 57 species were identified, belonging to six phyla (Platyhelminthes, Annelida, Sipuncula, Mollusca, Arthropoda and Echinodermata), of which 50 are considered here as new records for the Paraíba State. Annelids (Class Polychaeta) were the most representative taxa in Miramar and Seixas Beaches, while molluscs were dominant in Maceió Beach. This is the first study that includes an identification key, diagnostic features and distribution patterns worldwide and local (including new records) of the marine invertebrate fauna associated with rhodolith beds in northeast Brazil (State of Paraíba). Sampling events were performed in 2018, at low tide in the intertidal to shallow subtidal zones (1.5 and 4.0 m depth), in Miramar, Seixas and Maceió Beaches. A total of 17 species were found for the first time on Seixas Beach, as well as all identified species for Miramar and Maceió. This study tries to contribute to the knowledge of marine invertebrates in northeast Brazilian shallow habitats, providing a baseline for future environmental studies.

Polychaetes are typical marine invertebrates in the macroalgae and coral reefs environments, with a particular emphasis on tropical waters. In this study, 44 specimens were collected, belonging to 10 families, 13 genera and 13 species, among which the families Nereididae (with three species) and Amphinomidae (two spp.) were the most representative. The species Terebella plagiostoma (10 individuals), Ceratonereis singularis (9) and Eurythoe complanata (9) were the most abundant. This work represents the first study of polychaetes performed at the Morro de São Paulo region (Tinharé Island), a protected island from Northeast Brazil (state of Bahia). The samples (algae in the fringing reef ecosystems) were collected in 2015, at low tide in the intertidal to shallow subtidal zones. The species Hyboscolex longiseta Schmarda, 1861 is reported here for the first time in the South Atlantic Ocean. The errant polychaetes predominated at the collected samples (61.36% of the total abundance). These numbers evidence how little we know about coastal marine invertebrate fauna in Brazil and indicate the need for further sampling, especially on protected islands.

Abstract A first survey of mite species that ectoparasitize bats in the states of Ceará and Mato Grosso was conducted. The specimens of bats and their mites were collected in areas of the Caatinga and Pantanal biomes. A total of 450 spinturnicids representing two genera and ten species was collected from 15 bat species in the Private Reserve of the Natural Patrimony Serra das Almas, Ceará State, Northeast Brazil and 138 spinturnicids represented by two genera and four species were found in seven bats species collected in Private Reserve of the Natural Patrimony Sesc Pantanal, Mato Grosso State, Central-Western Brazil. The occurrence of Cameronieta genus and the species Mesoperiglischrus natali as well as four new associations (Periglischrus iheringi - Chiroderma vizottoi; P. micronycteridis - Micronycteris sanborni; P. paracutisternus – Trachops cirrhosus; Spinturnix americanus - Myotis riparius) are registered for the first time in Brazil.

Transgenerational effects are important for phenotypic plasticity and adaptation of marine invertebrates in the changing ocean. Ultraviolet-B (UV-B) radiation is an increasing threat to marine invertebrates. For the first time, we reported positive and negative transgenerational effects of UV-B radiation on egg size, fertilization, hatchability and larval size of a marine invertebrate. Strongylocentrotus intermedius exposed to UV-B radiation showed positive transgenerational effects and adaptation on egg size, hatching rate and post-oral arm length of larvae. Negative transgenerational effects were found in body length, stomach length and stomach width of larvae whose parents were exposed to UV-B radiation. Sires probably play important roles in transgenerational effects of UV-B. The present study provides valuable information into transgenerational effects of UV-B radiation on fitness related traits of sea urchins (at least Strongylocentrotus intermedius).

We have revised all the specimens of Araneidae from the Colombian Amazon Region in the Arachnological Collection of the Instituto de Ciencias Naturales at the Universidad Nacional de Colombia (ICN), in addition to the specimens collected between 2000 and 2004 by the authors in the lower Caquetá and Apaporis rivers (Amazonas and Vaupés, Colombia). A total of 77 new records for Araneidae in the Colombian Amazon are reported; 26 of these species are new records for the country and the region in addition to 15 more species known for Colombia but newly recorded in the region, the distribution of the remaining 36 species is expanded within the region. The genera Encyosaccus Simon 1865 (E. sexmaculatus Simon 1895), Hingstepeira Levi 1995 (H. folisecens Hingston 1932) and Micrepeira Schenkel 1953 (M. fowleri Levi 1995 and M. tubulofasciens Hingston 1932) are recorded for the first time in Colombia. From this revision, it is evident the great amount of new information available in museum collections. Due to the strategic geographic position of Colombia, species inventories in different localities of the Colombian Amazon Region are important to fill distributional gaps of many species in South America. This work contributes to the knowledge of geographic distribution patterns of orb-weaving species in Colombia and in the entire Amazon Region.

Brazil is considered one of the richest countries in Piper species in South America, with the genus being considered one of the most representative of the Brazilian Atlantic Forest. The aim of this study is to improve the knowledge about Piper in the northeastern region of Brazil, and to this end, we recorded the taxa that occur in the eastern portion of this region. Collection expeditions were conducted in the study area between August 2017 and July 2019, 21 herbaria were visited, and other internationally important collections were consulted online. Thirty tree taxa were registered, from which one was recorded for the northeastern region for the first time (P. nematanthera), besides 11 new records for at least one of the states. We present a synopsis with comments about morphology, habitat and phenology.

The present study reviews the taxonomy of the marine gastropods belonging to the family Eulimidae Philippi, 1853 from the continental slope off Northeast Brazil. The genera Abyssoaclis Barros, Mello, Barros, Lima, Santos, Cabral & Padovan, 2003 and Aclis Lovén, 1846 were not treated here. A total of 20 taxa were identified in this region, excluding Eulima hebes Watson, 1883, a species with a doubtful classification in Eulimidae. The species were assigned to the following genera: Costaclis Bartsch, 1947, Eulima Risso, 1826, Fusceulima Laseron, 1955, Melanella Bowdich, 1822, Ophieulima Warén & Sibuet, 1981, Sticteulima Laseron, 1955, Thaleia Warén, 1979, and Umbilibalcis Bouchet & Warén, 1986. The genera Sticteulima, Ophieulima and Umbilibalcis are reported for the first time in the southwestern Atlantic. Four species represent new records for the southwestern Atlantic. A redescription of the shell morphology is provided for: Costaclis egregia (Dall, 1889b), Melanella doederleini (Brusina, 1886), and Umbilibalcis lata (Dall, 1889b). Additional information to the original description are reported for other species. Melanella sarissa is considered as a synonym of Melanella cinca Dall, 1927. Six new species are described: Eulima cracentis sp. nov., Melanella paraabida sp. nov., M. adiastalta sp. nov., M. anapetes sp. nov., Sticteulima cabrali sp. nov. and S. canopusensis sp. nov. Lectotypes are designated for: Costaclis hyalina, C. egregia, Eulima ephamilla (Watson, 1883), E. psila and E. (?) hebes. Eulima sp. 1, Melanella sp. 1 and Melanella sp. 2 are potential new species, but the scarcity of material precludes a formal description at this moment.

AbstractThe species composition and population dynamics of mosquito adults trapped at 76 sites in southern Israel are described. Almost 200 000 specimens representing 23 species were collected. Five species, Aedes detritus (Haliday), Culiseta subochrea (Edwards), Culex antennatus (Becker), Cx. martinii Medschid and Cx. poicilipes (Theobald), are new records for this area, with Cx. poicilipes being recorded for the first time outside Africa. Six types of distribution patterns were discerned. The most abundant species was Cx. pipiens L. (79·7% of the total catch) followed by Ae. caspius (Pallas) (10%), Anopheles sergentii (Theobald) (2·1%), An. tenebrosus Dönitz (1·8%) and Cx. perexiguus Theobald (1·3%). All other species found each made up less than 1%. The spatial and temporal patterns of mosquito species in southern Israel are discussed.
