AbstractThe diets of the larvae of five anuran species are described (Discoglossus pictus, Bufo calamita, Hyla meridionalis, Pelobates cultripes and Rana perezi). They all are basically composed of three abundant categories of food: algae, detritus and phanerogams. Other rarely encountered food categories are pollen, fungi, animals, bacteria and protozoa. A classification can be deduced by relating the use of the space in the ponds, diets and several morphological characters of larvae of each species: a) bottom-dwellers —tadpoles with a depressed body form which feed mainly on detritus — b) water column users — tadpoles with larger dorsal tail crests and tail surfaces which feed mainly on algae and phanerogams.

AbstractDiets of both species studied were basically composed of algae and detritus. For Pelodytes punctatus, other food types exhibited minor contributions to the diet. For Bufo bufo, phanerogams reached considerable proportions too and the frequency of animals may be considered noteworthy if related to other species in the area. Morphologically they seem to be both conditioned to bottom dwelling rather than to the use of water column.

Abstract: Tadpoles are abundant in the environments in which they occur and remain in aquatic habitats for longer periods than adults, being relatively easier to collect. Despite the increase in tadpole research in the past decade, our understanding of its morphological diversity remains limited. Here, we provide morphological characterizations for larvae of 15 anuran species that occur at Emas National Park (ENP) and its surroundings, in Goiás, and compare them with descriptions available in the literature for other locations. We also present an update of the list of anuran species known to the ENP, based on tadpole sampling. We found tadpoles from 15 anuran species, of which five represent new records for the park. Many species showed variations in morphological characters when compared with descriptions available in the literature for other locations, reinforcing the importance of describing larvae from different populations. Through the exploration of morphological characters, it is possible to make inferences about the functional diversity of the larvae and questions related to the homology of characters, in addition to assisting in the identification and taxonomic distinction of species. Studies with tadpole communities can generate key information about the factors that drive the anurans' richness and distribution and can provide support for establishing more consistent conservation strategies and management plans.

Duas Bocas is a small water supply reservoir (0.51 km²) located in a forested area (Duas Bocas Biological Reserve) (20º18'S and 40º28'W). Phytoplankton community was investigated by samplings weekly taken in the dry (July, 1998) and rainy (March 1999) seasons, at surface, euphotic/afotic boundary, and at the bottom of the water column. A total of 76 taxa was identified with the majority of Chlorophyceae (Chlorococcales) (37.3 %), Conjugatophyceae (Desmidiales) (26.7 %), and Cyanobacteria (Chroococcales, Nostocales e Oscillatoriales) (22.7 %). In addition, Euglenophyceae, Dinophyceae, Cryptophyceae, and Chrysophyceae totalized 13.3 %. The predominant genera were Staurastrum, Staurodesmus, Cosmarium, Desmodesmus, Ankistrodesmus, and Monoraphidium. Regarding to the frequency of occurrence, most of the rare and constant species were belong to Chlorophyceae (Chlorococcales) and Conjugatophyceae (Desmidiales) and Cyanobacteria, respectively. According to the literature, most of the species presented cosmopolitan distribution. Among the identified taxa, 44 species (57.9 %) are the first citation for the State of Espírito Santo.

Two New Species

Lophoturus queenslandicus Verhoeff, 1924 was the first penicillate millipede in the family Lophoproctidae collected from Cairns, a tropical region in Queensland, Australia, to be formally described. Specimens collected from this region in a recent study had the morphological characters known to define this genus. However, their body form and length, as well as dorsal colouration proved to be different, suggesting the possibility of more than one Lophoturus species. This assertion was supported by the results of a phylogenetic analysis of DNA extracted and sequenced using 18S and COI regions from L. queenslandicus and two undescribed species from this genus. Specimens preserved in ethanol can prove difficult to confidently identify to species level because their colour gradually fades. Examination of live specimens with their body colour visible, together with morphological characters and DNA analysis is the most reliable way of correctly distinguishing between these three species. Two new species, L. boondallus sp. n. and L. molloyensis sp. n. collected in Queensland, Australia are described.

Present review is meant to update and bring the scattered records of anuran species from Bihar and Jharkhand at one place. A total of 22 valid species (19 from Bihar and 15 from Jharkhand) have been recorded from the existing literature and present new records from Jehanabad (Bihar) are dealt herewith in detail (relevant synonyms, common names, diagnostic features, size, altitudinal records, distribution in Bihar (including new records from Jahanabad), Jharkhand, rest of India and elsewhere and conservation status of each species and their role as potential biological controllers). Variations found in some morphological characters of species studied by various workers from different locations have been recorded.

AbstractThe amphibian community of the Biological Reserve of Doñana (SW Spain) is composed of 10 species, their period of larval occurrence commonly taking place from autumn to early summer, although it may vary from year to year in relation to the flooding conditions of ponds. A segregation is observed according to temporal use of temporary ponds by larvae of different species. Pelobates cultripes and Discoglossus galganoi tadpoles occur in ponds during their whole persistence, from flooding to drying up. Hyla meridionalis, Triturus marmoratus and Triturus boscai larvae commonly exploit a shorter temporal range, appearing about two months later until early summer. Bufo bufo, Bufo calamita and normally also Rana perezi have the shortest larval periods, of about two months. Rana perezi is also characterized by its delay in temporal use of the ponds in comparison with the other species. The flexibility of the larval period season is considered an adaptation to the unpredictability of temporary ponds. Thus, under certain climatic conditions, the two first groups of species may occur in the same temporal range.

A new species of Schwenckia (Solanaceae) from calcareous outcrops of the Serra Azul Biological Reserve in northern Minas Gerais, Brazil, is described and illustrated. Schwenckia aurantiaca is an annual plant characterized by a cylindrical corolla tube with five orange, linear appendages, an androecium with two stamens and three, unequal pilose staminodes, and a calyx that tears to the base in fruit. We discuss the morphological characters, habitat, and conservation status of the species, which is assessed as Critically Endangered.
