We provide a list of amphibians and reptiles of the Calakmul Biosphere Reserve in the southern half of the Mexican Yucatan, in the state of Campeche. The study area was sampled through opportunistic, transect and pitfall trap surveys conducted for three successive years. These surveys resulted in a total of 2,359 amphibian and reptile encounters, belonging to 20 amphibian and 69 reptile species from 24 total families. We present herein the records for one snake, one chelonian and two salamander species not previously recorded in the area.

The San Pedro Mezquital River is the seventh largest river in Mexico, and flows through the Sierra Madre Occidental into the Marismas Nacionales Biosphere Reserve, on the coast of the state of Nayarit. The present study is to conform a systematic checklist of fishes in the lower basin of the San Pedro Mezquital River. In total, 52 species were collected from 24 families. Four native species were collected (Atherinella crystallina, Poecilia butleri, Poeciliopsis latidens and Poeciliopsis prolifica) that are federally protected. Five of the collected species were new records for the state of Nayarit. This checklist constitutes a first approximation of the fish fauna present in the San Pedro Mezquital River. However, the construction of the Las Cruces dam upstream, will modify the basin hydrology, worsen the introduction of exotic species and create habitat loss, which can have immediate negative impacts on the fish communities in this region.

RESUMENLos estudios sobre la mastofauna del estado de Campeche se remontan a principios de 1900, con los naturalistas que realizaron extensas expediciones y comenzaron a describir las especies de mamíferos para la Península de Yucatán. Para el estado de Campeche se han reportan 125 especies de mamíferos, de las cuales 110 son terrestres y 15 de afinidad acuática, representadas en 13 órdenes, 34 familias y 92 géneros. El orden con mayor riqueza de especies es Chiroptera, seguido de Rodentia y Carnivora. El nivel de endemismos es bajo para el Estado; sin embargo, existen 21 especies endémicas a Mesoamérica. Aproximadamente el 40% de las especies de mamíferos del Estado se encuentra amenazada y en peligro de extinción. Por ejemplo, la foca monje del Caribe (Monachus tropicalis) fue abundante en las costas de Campeche, pero se extinguió el siglo pasado. Campeche mantiene las coberturas de selva más extensas de México, con más de 2 millones de hectáreas protegidas. En especial la Reserva de la Biosfera Calakmul y las Reservas Estatales Balam-Kú y Balam-Kin mantienen buenas poblaciones de especies amenazadas como el jaguar (Panthera onca), pecarí de labios blancos (Pecari tajacu) y tapir (Tapirus bairdii). Esto lo hace un estado prioritario para la conservación de la diversidad biológica. Palabras clave: Campeche, conservación, endemismo, extinción, mamíferos, riqueza.ABSTRACTStudies of the mammals of Campeche date back to the early 1900s, when scientists began describing species for the Yucatan Peninsula. Presently, there has been reported 125 species of mammals, 110 of which are terrestrial and 15 marine ones. Those species represent 13 orders, 34 families, and 92 genera. Order with highest species richness is Chiroptera, Rodentia and Carnivora. The level of endemism is low for the state; however, there are 21 species endemic to Mesoamerica. Approximately 40% of the state’s mammal species are threatened with extinction. The Caribbean monk seal (Monachus tropicalis) was abundant on the coast of Campeche, but became extinct last century. Campeche maintains the most extensive tracts of forest of Mexico, with more than 2 million hectares protected. The Calakmul Biosphere Reserve and state reserves Balam-Ku and Balam-Kin maintain good populations of endangered species such as the jaguar (Panthera onca), white-lipped peccary (Pecari tajacu) and tapir (Tapirus bairdii). This makes the state a priority for the conservation of biodiversity. Key words: Campeche, conservation, endemic, extinction, mammals, richness species.

AbstractKristianstads Vattenrike Biosphere Reserve [KVBR] is a UNESCO designated area of Sweden possessing high biological value. Although several studies on tardigrades inhabiting Sweden have been performed, the KVBR area has been neglected. The current study investigates the tardigrade fauna of five areas of the biosphere reserve and includes 34 samples of different substrates analysed quantitatively and qualitatively. In total, 33 species of tardigrades were found in the samples, including 22 new records for the Skåne region, 15 new records for Sweden, and four species new to science. Mesobiotus emiliae sp. nov., Xerobiotus gretae sp. nov., Itaquascon magnussoni sp. nov., and Thulinius gustavi sp. nov. were described with an integrative approach (when possible) using morphological characters (light, electron scanning, and confocal laser scanning microscopies) and molecular markers (ITS2, 18S, 28S, cox1). A new protocol to increase morphological data was developed recovering mounted specimens within old slides for SEM analysis. Emended diagnoses for the genus Itaquascon and the transfer of Platicrista itaquasconoide to the genus Meplitumen are proposed. This study enriches the knowledge of the tardigrade biodiversity both within the KVBR and in Sweden and contributes to the rapidly increasing number of tardigrade species reported worldwide. The 33 species identified in the KVBR area represents 28% of all water bear species found in Sweden so far. The restricted study areas and limited number of samples collected suggests that the KVBR is very rich of tardigrades.

The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

During a series of zooplankton surveys carried out from 2001 through 2005 off the coast of the state of Bahia, Brazil, 98 individuals of monstrilloid copepods were collected. These belong to five species (Monstrilla grandis, Cymbasoma cf. longispinosum, Cymbasoma cf. rigidum, Cymbasoma gracilis, and Cymbasoma quadridens). The first three are recorded for the first time in the Bahia coastal region. The geographical range of C. quadridens is expanded to the Brazilian northeastern coast. The results presented herein increase to nine the number of nominal species of Monstrilloida known from off Bahia; the environmental diversity of Caravelas Channel with highly productive areas and coral reef zones harbor an abundant and diverse monstrilloid fauna that should be surveyed in more detail.

ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.
