Carnivores typically exhibit cryptic behavior, which makes it difficult to study the ecology of species in this group. Camera trap bycatch can be a valuable source of important opportunistic records. In this short communication, we present rare records of carnivores in southern Brazil. The first record was of a tayra (Mustelidae) with anomalous coloration known as leucism. Other records were of a possible attempted predation event by two free-ranging dogs on lowland tapir (Perissodactyla, Tapiridae), a threatened species. Our remaining notable records consisted of intra and interspecific interactions of endangered felids (puma, ocelot and southern tiger cat).

Previously known from two specimens, Kaempfer's Tody-tyrant Hemitriccus kaempferi is a globally threatened species endemic to the southern Brazil Atlantic Forest. The first field observations of this little-known taxon were made in the 1990s and our data therefore provide the first published information on its natural history, including breeding biology, behaviour and vocalizations, as well as a new locality. As very little information has appeared in the literature concerning the identification of this species, we present notes on its plumage and habits. Remarks concerning the species's conservation prospects and the importance of the remaining forest in the vicinity of the type-locality for other threatened bird species are made.

Plantago commersoniana is a rare and threatened species, with a highly disjunct distribution, mainly in southern Brazil. This study expands its distribution to Mato Grosso do Sul state, in the Central-West region of Brazil, due to the discovery of a collection of this species from rocky grasslands in Ponta Porã. This new record is ca. 285 km distant from the nearest known population, in Yhú, Caaguazú department, eastern Paraguay. This is also the first record of a native Plantago species in Mato Grosso do Sul. Its conservation status according to the IUCN criteria is Endangered (EN).

Lack Of Knowledge

Bibimys is a genus still poorly known in its basic aspects, such as systematics, natural history and geographic distribution. In Brazil, only Bibimys labiosus is recorded, with occasional records spread in time and space. This paper presents four new localities of the species in Araucaria Forest, Paraná state, extending its distribution 150 km southwards. Additionally, a map of the known distribution of the species in Brazil and in Araucaria Forest is provided. The records point toward the lack of knowledge about basic aspects of the small non-flying mammal fauna in the plateau regions of Brazil.

Juliomys ossitenuis was previously known from the Atlantic Forest of southeastern Brazil, where it occurs in Dense Ombrophilous Forest. The record of the species in Floresta Nacional de Piraí do Sul, in Paraná state, confirmed by morphological and cytogenetic analyses, extends its distribution about 200 km southwards. This is the first record of the species in the state and in an area of Mixed Ombrophilous Forest (Araucaria Forest).

Viviania linostigma is restricted to the Brazilian territory, considered a threatened and endemic species of a small region in the Araucaria Forest. This species has been recorded only in southeast Santa Catarina State, and the extreme northeast of Rio Grande do Sul State, in Brazil. Here, we report four new records of V. linostigma for Rio Grande do Sul, expanding its known distribution by 262 km to the south and improving knowledge about the conservation status of the species. These novelties reinforce that species conservation requires more investment in fieldwork, especially in little sampled regions.

Aedes aegypti is the primary vector for the transmission of Dengue Fever (DF)/Dengue Haemorrhagic Fever (DHF). Entomological investigations on breeding habitats and larval prevalence of mosquitoes Aedes aegypti (L.) and Ae. albopictus (Skuse) were conducted from April to June 2009 in Kathmandu district, Nepal. Different water-filled containers were examined for the presence or absence of Aedes larvae. Larval survey techniques were used to obtain the House Index (HI), Container Index (CI) and Breteau Index (BI). The over all HI, CI and BI for Aedes aegypti were 6.25, 4.83, 9.37 and for Aedes albopictus were 6.25, 3.22 and 6.25 respectively. It was also observed that discarded tires lying outdoors were the preferred breeding habitats. No breeding was observed in other containers in April and May during this three months survey. Herewith, we report the first collection and identification of Aedes aegypti in Kathmandu during June, 2009. Indeed, this finding constitutes the first record from the capital of Nepal within the urban agglomeration of Basundhara and Gongabu-Balaju area.Therefore, DF/DHF transmission risk may occur locally if imported cases are introduced.  Key Words: Aedes aegypti; Ae. albopictus;  Kathmandu; First record; Dengue Fever.Journal of Natural History MuseumVol 24, 2009.Page:

A specimen of the ammonoid Perrinites Böse, 1919, was collected from the McCloud Limestone east of the summit of Tombstone Mountain, Shasta County, California. This is the first record of the genus in California, an important addition to the meager Permian cephalopod fauna of the state previously reported by Miller, Furnish, and Clark (1957) and Wilson (1984). It was found 1,100 feet (335 m) above the base of the formation in a coarse-grained limestone (Los Angeles County Museum of Natural History, Invertebrate Paleontology Section locality 6184) within fusulinid zone H of Skinner and Wilde (1965), considered to be late early or early middle Leonardian in age.

Faunistic inventories regarding natural history of amphibians and reptiles are considered scarce and very little is known about their assemblages in urban areas; the Pampas morphoclimatic domain, also known as Uruguayan Savannah or Southern Grasslands, is also poorly known regarding their faunal composition.  Herein, we present a checklist of 16 amphibian and 20 reptile species recorded over a course of four years in the Instituto Federal de Educação, Ciências e Tecnologia, Câmpus Pelotas-Visconde da Graça, in Pelotas, Rio Grande do Sul, Brazil. We also present data on natural history and discuss conservation efforts to be undertaken in the area, in one of the least preserved and known Brazilian morphoclimatic domains, providing insights into urban herpetofaunal diversity patterns and showing the importance of modified areas in its conservation.
