Isoetes is a worldwide aquatic plant group with ca. 250 species. In South America, Isoetes luetzelburgii is one of the few species that inhabits semi-arid areas. This is an endangered species known from only few collections, which causes uncertainty related to its morphological delimitation, distribution and conservation status. Efforts combining both field and herbarium investigations enabled us to identify several new populations in northern Brazil. In this study, we present a comprehensive assessment of the known distribution of I. luetzelburgii and provide a detailed description of the species. Because the holotype was never properly designated, we also provide the lectotypification for the name. The data presented here contribute to enhance our understanding of the taxonomy and natural history of this species. This understanding may also serve as a conservation tool for the protection of its populations.

Seed-finches are small-sized Neotropical granivorous birds characterized by extremely strong and thick beaks. Among these birds, the Great-billed Seed-Finch Sporophila maximiliani has been selectively and intensively trapped to the extent that has become one of the most endangered bird species in South America, yet its taxonomy remains complex and controversial. Two subspecies have been recognized: S. m. maximiliani (Cabanis, 1851), mainly from the Cerrado of central South America, and S. m. parkesi Olson (= Oryzoborus m. magnirostris), from northeastern South America. Originally, S. m. parkesi was diagnosed as being larger than the Large-billed Seed-Finch, S. c. crassirostris (Gmelin, 1789), but proper comparisons with S. m. maximiliani, which is larger than S. c. crassirostris, were never performed. Here we provide a review of the taxonomic and nomenclatural history of S. maximiliani, reevaluate the validity and taxonomic status of the subspecies based on morphological characters, and significantly revise its geographic distribution. Analyses based on plumage patterns and a Principal Component Analysis of morphometric characters indicated that S. m. parkesi is most appropriately treated as a synonym of the nominate taxon, which results in a monotypic S. maximiliani comprising two disjunct populations. Further, we conducted systematic searches for S. maximiliani in Brazil, in an attempt to obtain natural history information. After more than 6,000 hours of fieldwork in 45 areas of potential and historical occurrence, S. maximiliani was located only in two sites, in marshy environments called veredas, confirming the critical conservation status of this species, at least in Brazil. We discuss the conservation potential for, and the problems involved with, captive breeding of S. maximiliani for reintroduction into the wild.

Abstract This paper will explore the significance of the expeditions under- taken by Wanda Hanke (1893-1958) in South America, of the networks she established in the region, as well as of her contributions to ethnological studies, in particular her compilation of extensive data and collections. Through Hanke's experience, it is possible to elucidate aspects of the history of ethnology and that of the history of museums in Brazil, as well as to emphasize the status of female participation in these areas. Wanda Hanke spent 25 years of her life studying the indigenous groups of Argentina, Bolivia, Brazil and Paraguay and collecting ethnological objects for natural history museums. Trained in medicine and philosophy, she began to dedicate herself to ethnological studies in her forties, and she travelled alone, an uncommon characteristic among female scientists in the 1940s, in Brazil.

A New Species

AbstractA new species of tyrant flycatcher (Suiriri islerorum) is described from the cerrado region of Brazil and adjacent eastern Bolivia. The species previously had been confused with Suiriri suiriri affinis, with which it is syntopic at multiple sites. The new species was first identified by voice. Although cryptically similar to S. s. affinis in many respects, the new species is readily identified by all vocalizations, bill size, color pattern of the tail, and shape of the central rectrices. Most distinctive are the male–female duets, which are accompanied by dramatic wing-lifting displays not performed by any congeners. Reciprocal playback experiments of tape-recorded vocalizations demonstrated that the new species and S. s. affinis do not respond to one another's vocalizations. We provide information on the natural history of the new flycatcher, along with spectrograms of its various vocalizations. We also provide vocal analysis of all other named taxa in Suiriri, and discuss the various intrageneric relationships. In particular, S. s. affinis and S. s. bahiae, although distinct morphologically, are vocally and behaviorally similar, and respond to one another's vocalizations in playback experiments.

Dry Deciduous Forest

Reptiles are key animals in vertebrate communities in most ecosystems. However, there is little information on their diversity and abundance in dry forests of Ecuador. Between 2013 and 2014 we studied the reptile diversity and natural history of the Puyango Protected Forest, on the border between the province of Loja and El Oro, Ecuador. This area protects relicts of dry deciduous forest in hills and patches of semi-deciduous forest around ravines. We used belt transects in three different streams and irregular band transects in trails, together with pitfall traps, funnel traps, and litter quadrants. The richness of the Puyango Protected Forest represents a small percentage of the Ecuadorian reptile diversity, but covers much of the representative phylogenetic groups of tropical dry forests of the world. Sampling was effective to determine saurian diversity, but more sampling is needed to estimate snake diversity. Evidence of the presence of 21 species, divided into 10 families, was obtained; of which 14 are snakes (including a potential new species of the genus Epictia) and seven are lizards. Natural history is described for each species, including time and space use, and their conservation status is analyzed. The reptile community is characterized by a relative homogeneity over the vegetation remnants and the highest abundances correspond to saurian species.

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.
