Haageocereus: Taxonomy for the Conservation of the Genus in Peru.
The genus Haageocereus (Cactaceae) is mostly endemic o f Peru, occupying arid areas draining westwards o f Andes. In Peru, Haageocereus is found between 50 to 2800 m, from 79°54’W, 5°7’S (dept. Piura) to 70°52’W, 18°0’S (dept. Tacna). The understanding of this genus has been limited by several nomenclature problems...Moya-Mendez, Natalia Calderon

A synopsis of Oxypetalum (Apocynaceae) in Bolivia, with the description of one new species and a key to species in Bolivia.
We present a synopsis of Oxypetalum (Asclepiadoideae, Apocynaceae) in Bolivia. In addition, one new species, Oxypetalum urceolatum, is described, illustrated, and compared to its putative closest relatives. Oxypetalum urceolatum forms a complex with O. erianthum, O. brachystemma, O. dactylostelma, O. dombeyanum, O. molle, O. pearsonii, and O. fuscum. Morphologically, O....New records, Asclepiadoideae, IUCN Red List, Bolivia, Oxypetalum urceolatum, Taxonomy, Eudicots, and Biodiversity

Threatened status of neglected and underutilised Jatropha (Euphorbiaceae) species endemic to Mexico
Jatropha curcas is the best known species from the genus, an oilseed crop used for biodiesel production. It deserves attention as more species show similar oil content, phytochemical properties, or as a genetic resource in J. curcas breeding programs. The closest species to J. curcas show restricted distributions and are...Christensen, Cecilie ; Seal, Charlotte ; Rico-Arce, María de Lourdes

Progress, challenges and opportunities for Red Listing
Despite its recognition as an important global resource for conservation, the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species only provides assessments of extinction risk for a small and biased subset of known biodiversity. A more complete Red List can better support species-level conservation by indicating...Bachman, Steven ; Field, Richard ; Reader, Tom ; Raimondo, Domitilla ; Donaldson, John …

Abstract
Addressing Uncertainties in Machine Learning Predictions of Conservation Status.
Extinction risk assessments are increasingly important to many stakeholders (Bennun et al. 2017) but there remain large gaps in our knowledge about the status of many species. The IUCN Red List of Threatened Species (IUCN 2019, hereafter Red List) is the most comprehensive assessment of extinction risk. However, it includes...Walker, Barnaby ; Leão, Tarciso ; Bachman, Steven ; Lucas, Eve ; Nic Lughadha, Eimear

Caution Needed When Predicting Species Threat Status for Conservation Prioritization on a Global Scale
The recent Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) report highlighted the large scale of extinction risks to biodiversity (Díaz et al., 2019). Assessing species' extinction risk is vital for setting conservation priorities and the first step toward protecting particular areas or groups. A widely accepted approach to... -

Evidence-based guidelines for developing automated conservation assessment methods [PREPRINT].
Assessing species’ extinction risk is vital to setting conservation priorities. However, assessment endeavours like the IUCN Red List of Threatened Species have significant gaps in coverage of some taxonomic groups. Automated assessment (AA) methods are gaining popularity to fill these gaps, leveraging improvements in computing and digitally-available information. Choices made...Walker, Barnaby E. ; Leão, Tarciso C.C. ; Bachman, Steven P. ; Lucas, Eve ; Nic Lughadha, Eimear
