Glaziophyton Franch. is a monotypic bamboo genus (G. mirabile Franch.), narrowly endemic to the Campos de Altitude in the state of Rio de Janeiro, southeast Brazil. Five occurrence sites are known, but one is considered locally extinct and, at two sites, the species has not been recollected for several years. Due to its restricted geographical range G. mirabile is classified as a threatened species. In this study we report two new populations. These new records might change the species conservation status and the category of its extinction risk.

We report a female Physalaemus soaresi Izecksohn, 1965 collected at the Atlantic rainforest of Serra do Mendanha, municipality of Rio de Janeiro, state of Rio de Janeiro, southeastern Brazil. Known only from two localities (and probably extinct in one), P. soaresi is considered a threatened species in Brazil and presumably threatened in the state of Rio de Janeiro. Despite the new record, P. soaresi still fits into the status of endangered and requires the full protection of all areas where it occurs.

Taxonomic Groups

Threatened species lists are widely consulted as sources of information on the conservation status of species. However, their application to planning for conservation is limited because they have not been developed systematically, and because the criteria used to judge extinction risk are subjective. Recently, new proposals have been made to increase the broader usefulness of these lists, and some elements of these proposals are reviewed here. Apart from indicating the geographical and taxonomic groups containing most threatened species, these lists can provide other kinds of information. Some data from threatened species classifications using quantitative criteria provide a new method for estimating extinction rates in a variety of vertebrate taxa. This analysis suggests that over the next 100 years, the extinction rate could be as high as 15-20% in these groups. These values are comparable to those based upon extrapolations from species-area curves. However, allocating threatened species categories is only a first step towards developing rational systems for setting conservation priorities. These systems will need to consider a quite different set of variables, including those for incorporating species conservation priorities in area-based planning

ABSTRACT Pirá, Conorhynchos conirostris (Valenciennes, 1840), a large migratory catfish endemic to the São Francisco River (SFR), is listed as threatened in the red lists of both Brazil and the state of Minas Gerais. Although fishing for pirá has been prohibited, it is still an important fishery resource, particularly in the middle SFR. We used historical and current occurrence and abundance data regarding pirá to determine if it meets the IUCN criteria of a threatened species. Pirá occurs in the main course of the SFR as well as in its major tributaries. Unlike the most well-known migratory fishes of the SFR, pirá does not use floodplain lakes as nurseries. In the first half of the 20th century, pirá occurred from the upper to the lower SFR. Currently, it is most abundant in the middle SFR, and is rare in the upper SFR and even rarer in the sub-middle SFR. Pirá has not been captured in the lower SFR since around the mid-1980’s. Despite the reduction in its geographic distribution, we did not find evidence to justify considering pirá as threatened. Thus, we recommend that it be removed from the red lists of Brazil and the state of Minas Gerais.

IUCN Red Lists have been a valuable tool to prioritize conservation plans in endemic neotropical frogs. However, many areas in this region are poorly known in terms of their diversity and endemism. Based on examined museum specimens of the threatened species Pristimantis penelopus we revised its geographic distribution and determined the habitat suitability using niche modeling techniques. Using a mitochondrial fragment of COI gene, we determine the phylogenetic position and the extent of the genetic variation across its distribution in Colombia. We present the first records of P. penelopus for the Cordillera Oriental, the western versant of Cordillera Occidental and the northern portion of the Cauca river basin. Based on the molecular phylogenetic analysis, Pristimantis penelopus belongs to the P. ridens series sensu Padial et al. (2014). The mean of intraspecific genetic variation is 2.1% and the variation among population ranges between 2.3 and 3.5%. The genetic distance between the western populations and the Magdalena Valley populations suggests a potential phylogeographic break in northwestern Antioquia. We expand the realized distribution by 258 kilometers north, 200 km east and 223 km northwest. Based on our results and according to the IUCN criteria we propose a new category for the species and highlight the need to increase the surveys in poorly known regions to better understand the geographic distribution and conservation status of listed species.

Herein, we report new records of the treefrogs Dendropsophus anceps and Itapotihyla langsdorffii for the state of Minas Gerais, southeastern Brazil. Both species are known from several localities in the Atlantic Rainforest domain, but their presence in state of Minas Gerais is restricted to few localities. The present records reinforce the importance of field surveys for improving the knowledge about the geographic distribution and conservation status of Brazilian amphibians.

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.

Abstract: This study presents a synopsis of the tribe Cocoseae (Arecaceae) for the Maranhão state, which was based on the descriptive analysis of voucher specimens of national and international herbaria, from loans, collection visits, digital platforms, and materials collected in expeditions. Twenty-five species belonging to seven genera were identified. The genus Bactris Jacq. ex Scop. was the most representative with seven species, followed by Attalea Kunth. (five spp.), Syagrus Mart. (five spp.), Astrocaryum G. Mey. (three spp.), Desmoncus Mart. (three spp.), Acrocomia Mart (one spp.), and Allagoptera Nees (one sp.). Four new records of occurrence were found for Maranhão: Allagoptera leucocalyx (Drude) Kuntze, Attalea barreirensis Glassman, Attalea phalerata Mart. ex Spreng. and Syagrus glazioviana (Dammer) Becc. This paper presents a taxonomic key for the species, as well as geographic distribution maps and photographic plates with the distinguishing characteristics for each taxon. Besides the taxonomic characteristics, common names, ecological data, and conservation status are included.

Abstract Few marine taxa have been comprehensively assessed for their conservation status, despite heavy pressures from fishing, habitat degradation and climate change. Here we report on the first global assessment of extinction risk for 300 species of syngnathiform fishes known as of 2017, using the IUCN Red List criteria. This order of bony teleosts is dominated by seahorses, pipefishes and seadragons (family Syngnathidae). It also includes trumpetfishes (Aulostomidae), shrimpfishes (Centriscidae), cornetfishes (Fistulariidae) and ghost pipefishes (Solenostomidae). At least 6% are threatened, but data suggest a mid-point estimate of 7.9% and an upper bound of 38%. Most of the threatened species are seahorses (Hippocampus spp.: 14/42 species, with an additional 17 that are Data Deficient) or freshwater pipefishes of the genus Microphis (2/18 species, with seven additional that are Data Deficient). Two species are Near Threatened. Nearly one-third of syngnathiformes (97 species) are Data Deficient and could potentially be threatened, requiring further field research and evaluation. Most species (61%) were, however, evaluated as Least Concern. Primary threats to syngnathids are (1) overexploitation, primarily by non-selective fisheries, for which most assessments were determined by criterion A (Hippocampus) and/or (2) habitat loss and degradation, for which assessments were determined by criterion B (Microphis and some Hippocampus). Threatened species occurred in most regions but more are found in East and South-east Asia and in South African estuaries. Vital conservation action for syngnathids, including constraining fisheries, particularly non-selective extraction, and habitat protection and rehabilitation, will benefit many other aquatic species.
