An updated list of the mammals of Durango state, Mexico was built from literature records and Museum specimens. A total of 139 species have been recorded, representing 28.3 % of the Mexican terrestrial mammals, and 25.1 % species more compared to the previous account. Two species have been extirpated from the state, 23 are endemic to Mexico. Four major ecoregions have been previously defined for the state, Arid, Valleys, Sierra, and Quebradas. Species richness is highest at the Quebradas, a tropical ecorregion, whereas the aridlands are the least species-rich. The Sierra has the highest number of endemic species (11) followed by Quebradas (7), Valleys and Arid (3). Despite the fact that Durango harbors one of the largest diversities of mammals of the country, conservation efforts are minimal, and the current protected areas do not include the most species-rich regions. The current rate of anthropogenic modification in the state makes urgent to put in practice already existing plans to protect Durango’s unique biodiversity.

Abstract This study presents a floristic-taxonomic treatment of Psidium in the state of Espírito Santo, and is a result of fieldwork combined with analyses of herbarium specimens. Fourteen species of the genus were recognized in Espírito Santo state (P. brownianum, P. cattleianum, P. cauliflorum, P. guajava, P. guineense, P. longipetiolatum, P. myrtoides, P. oblongatum, P. oligospermum, P. ovale, P. rhombeum, P. rufum P. sartorianum, and Psidium sp.), accounting for about 34% of the species richness estimated for the genus in the Atlantic Rainforest biome. The species occur predominantly in lowland forests up to 700 meters above sea level. These areas are highly threatened due to urbanization of coastal areas and agricultural expansion in the state Espírito Santo. Therefore, the conservation of Psidium species in this state requires the creation of more lowland protected areas.

An updated list of the mammals of Chihuahua state, Mexico was assembled from the literature and from museum specimens. We documented 133 species (15 endemic to Mexico and 11 new for Chihuahua), representing 25 families, 75 genera, and 27.4% of the Mexican terrestrial mammalian fauna. Four species are probably extirpated from the state. Four major ecoregions have been defined for Chihuahua: Arid, Valleys, Sierra, and Quebradas. Species richness was the highest in Valleys, and consisted mostly of species with Nearctic affinities. In contrast, Quebradas were the least species-rich, but included mostly Neotropical species that occur only in this ecoregion of Chihuahua. Despite the fact that Chihuahua harbors considerable biodiversity and unique Mexican biomes, conservation efforts are insufficient. The current rate of anthropogenic modification in the state requires a comprehensive strategy if Chihuahua’s biodiversity is to be preserved.

We have modeled the ecological niche for 12 plant species belonging to the genusDavilla(Dilleniaceae) which occur in the Atlantic Forest of Brazil. This group includes endemic species lianas threatened by extinction and is therefore a useful indicator for forest areas requiring conservation. The aims are to compare the distribution and richness of species within the protected areas, assessing the degree of protection and gap analysis of reserves for this group. We used the Maxent algorithm with environmental and occurrence data, and produced geographic distribution maps. The results show that high species richness occurs in forest and coastal forest of Espírito Santo to Bahia states. The endemic species compriseD. flexuosa, D. macrocarpa, D. flexuosa, D. grandifolia, andD. sessilifolia. In the Atlantic Forest of southeastern Brazil, the following endemic species occur:D. tintinnabulataandD. glaziovii, with this latter species being included in the “red list” due habitat loss and predatory extractivism. The indicators of species richness in the coastal region of Bahia correspond with floristic inventories that point to this area having a high biodiversity. Although this region has several protected areas, there are gaps in reserves, which, combined with anthropogenic threats and fragmentation, have caused several problems for biodiversity.

Species richness and abundance of mammals in the Valle Alto Wildlife Rescue Centre and Wildlife Refuge, province of Manabí (Ecuador) Resumen Las poblaciones de mamíferos de la Región Costa de Ecuador han sido principalmente estudiadas dentro de las áreas protegidas, y son escasos los estudios realizados fuera de sus límites. El objetivo de este trabajo es determinar la riqueza de mamíferos en el Centro de Rescate y Refugio de Vida Silvestre Valle Alto en la provincia de Manabí mediante el uso de cámaras de foto-trampeo (168 noches/trampa en dos años) y transectos a pie para observaciones directas de los animales arborícolas. Las cámaras registraron 14 especies, y otras 4 especies fueron avistadas directamente. De estas 18 especies, 5 se encuentran amenazadas de extinción en Ecuador (a nivel nacional) según criterios de la UICN, y 4 casi amenazadas. Además, algunas de las especies registradas, como el yaguarundí (Herpailurus yagouaroundi), el perro de Sechura (Lycalopex sechurae), el margay (Leopardus wiedii) o el perezoso de dos dedos (Choloepus hoffmanni) cuentan con pocos registros en la región Costa. Las especies más abundantes fueron el armadillo (Dasypus novemcinctus), el guatuso (Dasyprocta punctata) y el ocelote (Leopardus pardalis). Estos datos sugieren que los bosques fuera de las áreas protegidas pueden albergar una importante comunidad de mamíferos incluyendo especies catalogadas como amenazadas, y su preservación es necesaria para asegurar la conservación de la fauna silvestre a nivel nacional. Palabras clave: cámaras trampas; mamíferos terrestres; diversidad de especies; fauna silvestre. Abstract The mammals populations of the Coast Region of Ecuador have been mainly studied inside of protected areas, and very few studies have been conducted out of their limits. This work shows the mammals species richness in the Valle Alto Wildlife Rescue Centre and Wildlife Refuge located in the Manabí province using camera traps (168 nights/traps in two years) and walking transects to detect arboreal mammals by direct observations. The camera traps recorded 14 species, and others 4 species were directly observed. Of this 14 species, 5 are classified as threatened to extinction in Ecuador (at national scale) according to the IUCN criteria, and 4 of them are listed as near threatened. Moreover, some of the recorded species, such as the Sechuran fox (Lycalopex sechurae), the jaguarondi (Herpailurus yagouaroundi), the margay (Leopardus wiedii) or the brown-throated Sloth (Choloepus hoffmanni), have few records in the Coast Region of Ecuador. The most abundant species were the nine-banded armadillo (Dasypus novemcinctus), the agouti (Dasyprocta punctata) and the ocelot (Leopardus pardalis). These results suggest that forests not included in the protected areas can harbour an important community of mammals including threatened species, and therefore its preservation is also necessary in order to conserve the wildlife species at a national scale. Keywords: camera traps; terrestrial mammals; species diversity, wildlife.

RESUMENEl estado de Nayarit se encuentra ubicado en el occidente de México, una región clave en el entendimiento biogeográfico de la mastofauna nacional. Se revisó la literatura disponible en referencia a los mamíferos que han sido registrados en el territorio, continental e insular, así como aguas territoriales del estado de Nayarit, México, encontrando que la mayor parte de los estudios se ha realizado en los últimos 50 años. Nueve órdenes, 30 familias, 88 géneros y 143 especies se conocen para el estado, siendo 32 endémicas del país y 6 para el estado. Los órdenes mejor representados son Chiroptera (61 especies), Rodentia (33), Cetacea (20) y Carnivora (17); existen 31 taxones descritos con base en ejemplares procedentes del estado. Es notable que las especies de murciélagos casi duplican las de roedores, cuando a nivel mundial y nacional son los roedores los más diversos. En lo que respecta a la distribución de las especies, hay una mayor presencia de especies con afinidades mesoamericanas (53) que neárticas (41) o neotropicales (29). Se han registrado 41 especies en algún listado de conservación nacional o internacional, incluyendo las 21 especies marinas.Palabras clave: Conservación, distribución, diversidad, mastofauna, occidente de Mexico. ABSTRACTThe state of Nayarit is located in western Mexico, a key region in the biogeographic understanding of the Mexican mastofauna. Available literature was reviewed in regard to both, the terrestrial and the marine mammals, known from state of Nayarit, Mexico. Nine orders, 30 families, 88 genera, and 143 species are currently known for the state, with 32 endemic species for the country and 6 at state level. Most diverse orders are Chiroptera (61 species), Rodentia (33), Cetacea (20), and Carnivora (17); with 31 taxa described based on specimens collected at the state. It is noteworthy that bat species almost duplícate the number of rodent species, while both at international and national level, rodents are the most abundant. Regarding the species distribution, most of them have Mesoamerican affinities (53), rather than Nearctic (41) or Neotropical (29). Forty-one species are listed within either national or international conservation lists, including the 21 marine species.Key-words: Conservation, distribution, diversity, mastofauna, western Mexico.

The 168 species of Dytiscidae known from Ethiopia are listed. For each species are given: original citation, synonyms, gross distribution, and distribution in Ethiopia with special reference to altitude and provinces. Besides literature records and museum specimens, 7300 individuals of 53 species collected by the junior author chiefly in the Arssi highlands in 1988 and 1989 are reported on. One syn. n. is presented: Rhantus longulus Regimbart, 1895 = Rhantus flavicollis Regimbart, 1887. Most of the 38 species endemic to Ethiopia occur only over 2000 m a.s.l., and the proportion of endemic species is highest in the Gondar, Shoa, Arssi and Bale provinces. The fauna of most provinces is poorly known. The Shoa province is best known, with 92 species recorded. In the Arssi highlands, the maximum local diversity was near 20 species in both lentic and lotic biotopes. The species richness of different supraspecific taxa is discussed and information is presented on co-occurrence of congeneric species and proportions of rare and frequent species.

Speothos Venaticus

AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.

According to its owners, the Forest of Seu Nico (FSN) from the Viçosa municipality, Minas Gerais, Brazil, never has been logged and is therefore considered a primary forest. Nevertheless, the forest patch suffered impacts due to selective wood and non-timber extraction, fragmentation and isolation. Aim of this study was to test if the FSN, despite impacts, preserved characteristics of primary forests, which are elevated percentages of non-pioneer (>90%), animal-dispersed (>80 %), understory (>50%) and endemic species (~40%). For that, all trees with diameter at breast height equal or major than 3.2 cm within a plot of 100 x 100 m were identified. With 218 tree species found within this hectare, the FSN's species richness is outstanding for the region. The percentages of non-pioneer (92 %), animal-dispersed (85 %), understory (55 %) and endemic species (39.2 %) from the FSN fulfill the criteria proposed for primary forest. Therefore, we conclude that the FSN maintained its characteristics as a primary forest which highlights its importance for the conservation of biotic resources in the region, where similar fragments are lacking or not described yet.

Mammal Diversity

Based on species occurrence records of museum collections, published literature, and unpublished records shared by mammalian experts, we compiled a distribution database for 59 terrestrial mammals populating the extensively protected Dobrogea Region of Romania. The spatial patterns of mammal distribution and diversity was evaluated and systematic conservation planning applied to identify priority areas for their conservation. The spatial analyses revealed that intensive sampling was not directly correlated to mammal diversity but rather to accessibility for inventory. The spatial prioritisation analysis indicated a relatively aggregated pattern of areas with a high or low conservation value with virtually no connecting corridors between them. The significant overlap between Natura 2000 sites and national protected areas induced an over-optimistic vision of the effectiveness and representativeness of existing Natura 2000 network for species found in Annexes II and IV of the Habitats Directive. These results represent a key step in identifying core areas for the protection of mammal diversity and dispersal corridors for improved connectivity, and to guide future conservation efforts in increasing the effectiveness of the existing protected areas in the context of environmental changes.
