And Behavior

During the exploration and mapping of new caves in Serra do Ramalho karst area, southern Bahia state, cavers from the Grupo Bambuí de Pesquisas Espeleológicas - GBPE (Belo Horizonte) noticed the presence of troglomorphic catfishes (species with reduced eyes and/or melanic pigmentation), which we intensively investigated with regards to their ecology and behavior since 2005. Non-troglomorphic fishes regularly found in the studied caves were included in this investigation. We present here data on the natural history of two troglobitic (exclusively subterranean troglomorphic species) fishes - Rhamdia enfurnada Bichuette & Trajano, 2005 (Heptapteridae; Gruna do Enfurnado) and Trichomycterus undescribed species (Trichomycteridae; Lapa dos Peixes and Gruna da Água Clara), and non-troglomorphic Hoplias cf. malabaricus, probably a troglophile (able to form populations both in epigean and subterranean habitats) in the Gruna do Enfurnado, and Pimelodella sp., a species with a sink population in the Lapa dos Peixes.

History Of

Ecuador has the biggest number of amphibian species per unit of area in the world (425 species in 283,560 km2). In the last decade, conservative estimates indicate that at least 26 species of Ecuadorian amphibians have declined or gone extinct. The reasons for this crisis are not clear but have been related to habitat destruction, climate change, and/or diseases, such as chytridiomycosis. The Río Palenque Science Center (RPSC) was among the last remnants of tropical rainforest in the western lowlands of Ecuador. Twenty years ago, investigations done by R. McDiarmid, Ken Miyata and others lead to the discovery of an amazing herpetofauna, including several undescribed species. However, the expansion of the agricultural frontier and transformation of the forest remnants into oil palm and banana plantations destroyed this site. Among the species identified from RPSC were five species of glass frogs (family Centrolenidae): Centrolene prosoblepon, Cochranella spinosa, Hyalinobatrachium fleischmanni, Hyalinobatrachium sp. (cf. valerioi), and an undescribed species of the genus Centrolene. This research analyzed the morphological characters and natural history of the five glass frogs of RPSC in order to describe the new species of Centrolene from RPSC, which seems to be critically endangered, if not extinct. The new species is characterized by a combination of the following characters: 1) distinctive coloration in life with dark flecks and yellow dorsolateral stripes on a green dorsum; 2) parietal peritoneum white, covering about ½ of the venter, pericardium white, liver and stomach without guanophores, large intestine with guanophores; 3) presence of exposed prepollical spines; 4) humeral spines in males; 5) unique glandular nuptial pad between fingers I and II; and 5) reddish iris.

Oncogenic Hpv

Up till now human papillomaviruses (HPV) draw attention of biologists and clinicians owing mostly to the fact that some members of this group cause cervical cancer in women. However it is clear that both women and men take part in HPV distribution throughout population. Data get accumulated on peculiarities of HPV natural history in men when compared with women, as well as on capability of oncogenic HPV to induce cancer in several male organs. The present paper is an attempt to synthesize literature data on specific features of HPV natural history in men. Elucidation of these features is important for working out efficient approaches for prevention of HPV-associated malformation with regard to gender specificities.

I. Some Observations relative to the natural History of the insect which secretes a Sort of wax, called white Lac. The matter which is the subject of the following observations and experiments, was first noticed by Dr. Anderson of Madras, about the year 1786, in a letter to the governor and council of that place, when he says, nests of insects resembling small cowry shells were brought to him from the woods by the natives, who eat them with avidity. These supposed nests he shortly afterwards discovered to be the coverings of the females of an undescribed species of coccus; and having noticed, in the Abbé Grosier's Account of China, that the Chinese collect a kind of wax, much esteemed by them, under the name of Pé-la, from a coccus deposited for the purpose of breeding on certain shrubs, and managed exactly in the same manner as the Mexicans manage the cochineal insect, he followed the same process with his new insects, and shortly found means to propagate them with great facility on several of the trees and shrubs growing in his neighbourhood. On examining the substance, he observed in it a very considerable resemblance to bees wax; and noticed, moreover, that the animal which secretes it provides itself, by some means or other, with a small quantity of honey, resembling that produced by our bees; and he complains in one of his letters, that the children whom he employed to gather it were tempted by its sweetness to eat so much of what they collected, as to diminish materially the produce of his crop. It is also believed that the white lac possesses medicinal qualities.

Natural history of the rare and endangered snake Atractus ronnie (Serpentes: Colubridae) in northeastern Brazil. The habitat use, activity period, sexual dimorphism, morphological variation, reproduction and diet composition of this fossorial and nocturnal snake are reported. The snakes were captured between 2008–2014 in the Chapada do Araripe in northeastern Brazil, and were collected by active visual searches, as well as in pitfall traps with drift fences. Although females are larger than males, the males have longer tails, and scale counts differ between the sexes. Reproduction is seasonal, occurring during the rainy season. Brood sizes rang from one to four eggs. Atractus ronnie preys on earthworms, in addition to ants (Crematogaster sp.) and insect larvae.
