Background. Red Lists have been traditionally used as the instruments to guide conservation strategies to avoid extinctions. There is little objection to the idea that categorizing species according to their risk of extinction is a good way to prioritize and implement conservation actions; however, there is little consensus in the best way to do this categorization, and different countries have developed different methods according to their specific needs. The scope of this paper is to contrast the Mexican Risk of Extinction Assessment Method (MER) and the one used by the IUCN Red List, and test how simple, objective and transparent are them. Methods. In order to compare the we performed a search within IUCN´s data base to find species ranked as critically endangered which have not been assessed by the MER. We picked 5 species from the rodent genus Habromys and performed a literature review to assess them through the MER guidelines; we then compared the outcomes with UICN Red List. Results. The five assessed species of cloud forest rodents yield equivalent results through both the MER and IUCN assessments; however, the information asked for by the MER was scant for all the species, and we argue that the results of the assessments are thus not entirely objectives. Moreover, we found that the MER is not a simple method to use due to ambiguities of the criteria. Discussion. The aim of risk assessments is to clearly define the conservation status of a given species, displayed in a simple, transparent, objective, way, which can be relevant in terms of scope and impact on conservation actions. Unfortunately the MER does not fulfil all these requirements, potentially compromising conservation actions. As a result, we propose that it is time reevaluate the current version of the Mexican Risk of Extinction Assessment Method.

In The Wild

A recent complete assessment of the conservation status of 5487 mammal species demonstrated that at least one-fifth are at risk of extinction in the wild. We retrospectively identified genuine changes in extinction risk for mammals between 1996 and 2008 to calculate changes in the International Union for Conservation of Nature (IUCN) Red List Index (RLI). Species-level trends in the conservation status of mammalian diversity reveal that extinction risk in large-bodied species is increasing, and that the rate of deterioration has been most accelerated in the Indomalayan and Australasian realms. Expanding agriculture and hunting have been the main drivers of increased extinction risk in mammals. Site-based protection and management, legislation, and captive-breeding and reintroduction programmes have led to improvements in 24 species. We contextualize these changes, and explain why both deteriorations and improvements may be under-reported. Although this study highlights where conservation actions are leading to improvements, it fails to account for instances where conservation has prevented further deteriorations in the status of the world's mammals. The continued utility of the RLI is dependent on sustained investment to ensure repeated assessments of mammals over time and to facilitate future calculations of the RLI and measurement against global targets.

Abstract—The recent rediscovery of Jatropha riojae, which was considered as probably extinct, led to a taxonomic re-evaluation of the species due to its problematic circumscription with respect to morphologically similar species of Jatropha section Loureira subsect. Loureira. Based on our study, J. riojae is accepted, taxonomic clarifications are made, including the designation of a lectotype for the name, a complete description of vegetative and reproductive structures is provided, and the species is illustrated and compared to others with which it has been confused. The geographical distribution of J. riojae is clarified as endemic to the municipality of Acatlán, Puebla, Mexico in the south of the Balsas River Basin. To determine the conservation status of the species, the risk assessment method of the Mexican Red List (NOM 059-SEMARNAT-2010) was applied, indicating that J. riojae should be assigned to the “Endangered” category. A re-evaluation of the species under the IUCN criteria indicated that it should be assigned in the “Critically Endangered” (CR) category.

SummaryAmazona lilacina is a threatened species endemic to Ecuador, existing across a patchwork of mangroves, lowland coastal forests, agricultural and community owned land. The species was described in 2014 and listed as ‘Endangered’ on the IUCN Red List, however, full assessment of the population was lacking. Using a combination of field observations, roost surveys and community questionnaires, conducted over the last 20 years, we provide up-to-date information on the species’ Extent of Occurrence, estimate its global population size, and evaluate its level of threat. Our results suggest the species occurs across an area of 19,890 km2 in three distinct geographically isolated subpopulations. Roost surveys across the range estimate the minimum remaining population at 741–1,090 individuals and we present evidence to suggest a 60% decline over the past 19 years in one part of the species’ range. We conducted community questionnaires with 427 people from 52 communities. The presence of pet parrots was reported in 37 communities, including 17 communities which reported pet A. lilacina. From this we predict that over half of all communities within our study area keep parrots as pets and at least 96 communities keep A. lilacina. Our findings justify an IUCN Red Listing of at least ‘Endangered’ for this species and highlight the need for conservation support. In order to assess population health in more detail, further research is required to assess genetic diversity and roost dynamics, and to identify areas that may be important for feeding and nesting throughout the range. As many of these areas are likely to overlap with community owned land, we suggest that future conservation actions should revolve around, and be led by, these communities.

Declines in endemic species have significant impact on global biodiversity loss. More efforts need to be harnessed to further protect endemic species from the current global extinction crisis. This study evaluated the current conservation status, factors responsible for risk of extinction and the trends in populations of Leucadendron, a plant genus endemic to the Cape region in South Africa. The SANBI (South African National Biodiversity Institute) Red List was employed in this study. The results revealed that over 50% of taxa in this genus are threatened and most of the species are exposed to habitat destruction and the presence of invasive species. It was also discovered that two species of this genus are currently extinct, which implies this genus is facing a high risk of extinction. More efforts, such as designing effective methods of controlling forces responsible for the risk of extinction of taxa in this genus, should be put in place to prevent their complete extirpation in future.

Vulnerability of Dytiscidae species (Coleoptera) in Cuba. Cuba has one of the richest diving beetles species diversity in the Caribbean islands. However, Cuban Dytiscidae remain scarcely studied, and there is need to identify those species and habitats that urgently require effective conservation actions. Here we aim to identify the threatened taxa of the family Dytiscidae in Cuba according to their degree of vulnerability. For that, we compiled distributional data on the Cuban fauna, including data from literature, collections and own samplings carried out between the period 2000 and 2014. In addition, the vulnerability of the species was evaluated using a methodology that combines six criteria regarding both species and habitat attributes. This analysis of vulnerability was completed to 50 (94 %) out of 53 Cuban species. Five species (9 %) were identified as highly vulnerable, 20 (38 %) moderately and 25 (48 %) as having low conservation status. The five most threatened species were Laccodytes cobrinae, Laccophilus alariei, Copelatus barbouri, C. darlingtoni, and Desmopachria glabella. These species are endemic to Cuba and characterized by highly localized populations and low abundance as well as high habitat specificity. Thus, we propose the inclusion of these five species in both the red list of Cuban fauna and the IUCN Red List (under the category of “Vulnerable”). In addition, not all areas where these species were found belong to the National System of Protected Areas of Cuba. Thus, we suggest the inclusion of the Laguna Base Julio A. Mella and the North of Imías, and to develop effective management measures to prevent the alteration of these aquatic ecosystems. Rev. Biol. Trop. 66(2): 709-721. Epub 2018 June 01. Key words:

AbstractThe extremely rare Aquilegia paui (Ranunculaceae) was described in 1920 but was not found again until 1999, when it was discovered in the Parc Natural dels Ports in Tarragona Province, Spain. This species had been confused with the widespread A. vulgaris and consequently its taxonomic and conservation status had been misinterpreted. Based on the limited range of A. paui and the level of disturbance of its habitat we recommend that it is categorized as Endangered on the IUCN Red List. We summarize the conservation actions available for such extremely narrow endemic plant species and make appropriate recommendations for the conservation of A. paui.

Species Specific

Approximately 20% of carnivorous plant species are threatened worldwide. Key threats include habitat degradation and loss, altered fire regimes or hydrology, and collection of plants for trade. In most parts of the world, conservation efforts are focused on documenting the threats to species, a necessary precursor to the implementation of conservation strategies and actions. To date, North America is the only region where species-specific conservation actions have been implemented. In southwestern Australia, inappropriate land management practices and urbanization threaten a number of species, whereas in Southeast Asia, Nepenthes pitcher plants are threatened by habitat destruction and collection for trade. Some iconic carnivorous plant species in these two biodiversity hotspots are critically endangered and the need for recovery plans and actions is urgent. There is an equally urgent need for baseline data on the conservation status of carnivorous plant species from other regions, particularly Africa and South America.
