Mesoamerican Cypripedium: Mycorrhizal Contributions to Promote Their Conservation as Critically Endangered Species. [PDF]

Plants (Basel), 2022
In the valuable orchid genus Cypripedium, the section Irapeana consists of a distinctive group of Mesoamerican species that is formed by Cypripedium dickinsonianum Hágsater, C. irapeanum Lex., and C. molle Lindl. All lady slipper orchids exhibit different distributions and abundances.

Ecological niche modelling of a critically endangered species Commiphora wightii (Arn.) Bhandari using bioclimatic and non-bioclimatic variables

Ecological Processes, 2023
Background The aim of this study is to examine the effects of four different bioclimatic predictors (current, 2050, 2070, and 2090 under Shared Socioeconomic Pathways SSP2-4.5) and non-bioclimatic variables (soil, habitat heterogeneity index, land use ...

Reproductive Biology of Astragalus argaeus (Fabaceae), a critically endangered endemic species [PDF]

Anais da Academia Brasileira de Ciências, 2021
Astragalus argaeus is an endemic plant species that is under critical risk of extinction. Here we investigated its population census, breeding system and reproductive success to determine the main factors affecting restricted distribution of this species. According to the results from pollination experiments, A.

Faecal DNA to the rescue: Shotgun sequencing of non-invasive samples reveals two subspecies of Southeast Asian primates to be Critically Endangered species. [PDF]

Sci Rep, 2020
A significant number of Southeast Asian mammal species described in the 19 th and 20 th century were subsequently synonymized and are now considered subspecies.

Eucalyptus cryptica (Myrtaceae): a critically endangered new species

Australian Systematic Botany, 2023
Recognition that the critically endangered mallee Eucalyptus sp. Cattai (Gregson s.n. 28 Aug 1954) is a distinct species has been complicated by close morphological similarity between it and other members of E. subgenus Symphyomyrtus section Latoangulatae series Annulares. Recent genomic evidence has demonstrated that it is distinct from other species.

Wide-Geographic and Long-Term Analysis of the Role of Pathogens in the Decline of Pinna nobilis to Critically Endangered Species

Frontiers in Marine Science, 2022
A mass mortality event (MME) affecting the fan mussel Pinna nobilis was first detected in Spain in autumn 2016 and spread north- and eastward through the Mediterranean Sea.

The complete chloroplast genome of Pterospermum kingtungense, a Critically Endangered species. [PDF]

Mitochondrial DNA B Resour, 2018
Pterospermum kingtungense (Pterospermum, Sterculiaceae) is a Critically Endangered species. In this study, we reported a complete chloroplast genome of P. kingtungense based on high-throughput sequencing data. The size of chloroplast genome was 162,929 bp, including a large single-copy region (LSC: 91,535 bp) and a small single-copy region (SSC: 20,464

Phylogenetics and Biogeography of Lilium ledebourii from the Hyrcanian Forest

Diversity, 2022
Lilium ledebourii (Baker) Boiss is one of the most endangered lilies, restricted to only a few small and fragmented areas in the Hyrcanian forest. This study aimed at evaluating the taxonomy of this unique Iranian lily and reconstructing divergence time ...

Genomic signatures of inbreeding in a critically endangered parrot, the kākāpō

G3: Genes, Genomes, Genetics, 2021
Events of inbreeding are inevitable in critically endangered species. Reduced population sizes and unique life-history traits can increase the severity of inbreeding, leading to declines in fitness and increased risk of extinction.
