A Dominant Founder Lineage Has Possible Fitness Costs for the Endangered Mexican Grey Wolf. [PDF]
ABSTRACT The Mexican grey wolf (Canis lupus baileyi) is an endangered and genetically distinct subspecies of grey wolf adapted to the warm climates of the southwestern United States and Mexico. Following centuries of eradication efforts, Mexican grey wolves were protected under the Endangered Species Act in 1976, prompting an international ex situ ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Downlisting and recovery of species assessed by the IUCN. [PDF]
Abstract Despite the increasing number of species assessed for extinction risk by the International Union for Conservation of Nature (IUCN) (163,040 species as of 2024), only about 1 in 1,000 have been downlisted due to genuine population improvement. Although this rare conservation achievement has been widely celebrated in several recent cases, some ...

Genetic origins and climate-induced erosion in economically important Asian walnuts. [PDF]
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Global drivers of the conservation-invasion paradox. [PDF]
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree. [PDF]
Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Mitogenomic and Metabarcoding Resources for the Study and Conservation of Keystone Neotropical Raptors [PDF]
We characterized complete mitochondrial genomes for nine keystone Neotropical raptors, including four threatened and five near‐threatened species, providing essential resources for phylogenetic and conservation studies. We also developed metabarcoding primers, enabling non‐invasive monitoring of Neotropical raptors via environmental DNA.
