Vegetation structure, carbon sequestration potential and species conservation in four agroforestry systems in Cameroon (Tropical Africa) Acta Botanica
Noumi,Valery Noiha; Djongmo,Victor Awe; Nyeck,Boris; Mbobda,Roger Bruno Tabue; Zapfack,Louis.
ABSTRACT As the rate of forest degradation continues to rise, agroforestry may serve as a way of conserving species and carbon sinks. The aim of this study was to assess agrobiodiversity and carbon sequestration potential in agrosystems in Cameroon. Three age groups of agrosystems were studied. Data were collected in 100x50 m2 quadrates. Density ranged from 53.17±0.08 to 1463±50.11; basal area from 2.07±0.00 to 988.39±16.13 m2/ha; Shannon diversity from 3.3±0.71 to 3.68±0.72; Carbon storage from 12.1±0.27 to 54.65±1.38 t C/ha for 1-10-year-old agrosystems with lowest values in neem; 34.78±0.87 to 71.34±1.6 t C/ha for 10-20-year-old stands with lowest values in cashew; 28.24±0.04 to 108.51±2.46 t C/ha for +20-year-old stands with highest values in...

On the taxonomic identity and conservation status of Campomanesia ilhoensis Mattos and C. viatoris Landrum (Myrtaceae) Acta Botanica
Oliveira,Marla Ibrahim Uehbe de; Funch,Ligia Silveira; Landrum,Leslie Roger.
(On the taxonomic identity and conservation status of Campomanesia ilhoensis Mattos and C. viatoris Landrum (Myrtaceae)). Based on a taxonomic study of Campomanesia Ruiz & Pavón in the state of Bahia, Brazil, we observed that C. ilhoensis Mattos and C. viatoris Landrum belong to the same taxonomic entity. Both names are legitimate and validly published; however, C. ilhoensis has priority over C. viatoris, which has been in use since 1984. In addition, the distribution of the more inclusive species is now known to extend from Bahia to Ceará. A new conservation status for this species is suggested because of a better knowledge of its distribution.

Conservação de hepáticas na Mata Atlântica do sudeste do Brasil: uma análise regional no Estado do Rio de Janeiro Acta Botanica
Costa,Denise Pinheiro da; Santos,Nivea Dias dos.
A União Internacional para Conservação da Natureza (IUCN) desenvolveu um guia para avaliação do grau de ameaça das espécies em escala regional, que foi a base para a reavaliação do status de conservação das hepáticas no estado do Rio de Janeiro, após quatro anos da primeira análise. Dos 360 táxons ocorrentes no estado, 75 foram categorizados como ameaçados, sendo dois criticamente em perigo (CR), oito em perigo (EN) e 65 vulneráveis (VU). Além desses, quatro táxons foram categorizados como quase ameaçados (NT) e 12 com dados deficientes (DD). O elevado número de táxons ameaçados no estado (21% da flora) reflete a importância do grau de conhecimento da flora para realização de análises de conservação. Em relação à distribuição dos táxons ameaçados dentro do...

Flagging a species as threatened: the case of Eptesicus taddeii, an endemic bat from the Brazilian Atlantic Forest Biota Neotropica
Bernard,Enrico; Nascimento,Jorge Luiz do; Aguiar,Ludmilla Moura de Souza.
The IUCN Red List is an important conservation tool. Although its criteria are used worldwide, in most cases the classification process per se is restricted to a group of experts with restricted or no participation of the general public. This may raise concerns from final Red List users, which, without knowing the data or procedures adopted by the experts, may argue on the outcomes, final classification adopted, or the overall use of the lists. IUCN recommends that all assessments must be backed up by data and justifications, making them as accurate and transparent as possible. We describe here the assessment of Eptesicus taddeii, a bat species endemic to the southern Atlantic Forest of Brazil, indicating how and why the species was flagged as Vulnerable -...

GAPeDNA: Assessing and mapping global species gaps in genetic databases for eDNA metabarcoding ArchiMer
Marques, Virginie; Milhau, Tristan; Albouy, Camille; Dejean, Tony; Manel, Stéphanie; Mouillot, David; Juhel, Jean‐baptiste; Dutta, Trishna.
Aim Environmental DNA metabarcoding has recently emerged as a non‐invasive tool for aquatic biodiversity inventories, frequently surpassing traditional methods for detecting a wide range of taxa in most habitats. The major limitation currently impairing the large‐scale application of eDNA‐based inventories is the lack of species sequences available in public genetic databases. Unfortunately, these gaps are still unknown spatially and taxonomically, hindering targeted future sequencing efforts. Innovation We propose GAPeDNA, a user‐friendly web interface that provides a global overview of genetic database completeness for a given taxon across space and conservation status. As an application, we synthetized data from regional checklists for marine and...

Geophila erythrocarpa (Rubiaceae), a new species from D.R.Congo and Zambia Naturalis
Dessein, S.; Vanthournout, S.; Niyongabo, F..
The species Geophila erythrocarpa (Rubiaceae) is described and illustrated. The new species is restricted to dry, dense forests of the Katanga province in D.R.Congo and the adjoining Copperbelt province in Zambia. The species is similar to and in the herbarium easily confused with G. obvallata from which it most clearly differs in having red instead of blue or black fruits. In flowering state, the two species can be separated by differences in calyx morphology. The new species shares the red-coloured fruits with G. afzelii, but differs from this species in the undivided stipules, the fewer-flowered inflorescences with smaller bracts, and details of the leaf coloration. The new species is further compared with all other Geophila species reported from Zambia...

A new, narrowly distributed, and critically endangered species of Characidium (Characiformes: Crenuchidae) from the Distrito Federal, Central Brazil Neotropical Ichthyology
Melo,Marcelo Roberto Souto de; Ribeiro,Mauro César Lambert de Brito; Lima,Flávio César Thadeo de.
ABSTRACT A new species of Characidium is described from the Cerrado biome, in Brasília, Distrito Federal, Central Brazil. The new species can be readily diagnosed by the presence of two or three longitudinal rows of dots along the body sides, absence of bars, by the short pectoral fin, which does not reach the vertical through the dorsal fin origin. Additional useful diagnostic characters are the scaled isthmus, absence of the adipose fin, and the terminal mouth. The new species is only known from the córrego Taquara and its tributaries, a tributary of ribeirão do Gama, upstream from lago Paranoá, in the upper rio Paraná basin. In accordance to the IUCN Red List Categories and Criteria, the new species is categorized as Critically Endangered.

Fisheries, life-history and conservation status of the catfish pirá Conorhynchos conirostris (Ostariophysi: Siluriformes) in Brazil Neotropical Ichthyology
Godinho,Alexandre Lima; Godinho,Hugo Pereira.
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...

Missing for the last twenty years: the case of the southernmost populations of the Tropical Mockingbird Mimus gilvus (Passeriformes: Mimidae) Rev. Bras. Zool.
Zanon,Mariana S.; Vale,Mariana M.; Alves,Maria Alice S..
The Tropical Mockingbird Mimus gilvus (Vieillot, 1808) is a widespread species in the Neotropics, but its southernmost populations in Brazil are ecologically (and possibly taxonomically) distinct, occurring only along the coast in restinga vegetation. Once considered the most common bird in restinga, it is becoming increasingly rare, likely due to habitat loss and illegal capture of nestlings. We conducted field surveys to provide an up-to-date distribution of the Tropical Mockingbird in the southernmost portion of the species' range, in the state of Rio de Janeiro, supplying an estimate of its current regional population size and conservation status. We surveyed 21 restinga remnants in Rio de Janeiro, covering all major restinga areas in the state. For...
