In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

Conservation Biology, Volume 40, Issue 2, April 2026.
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

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

TAXON, Volume 75, Issue 1, February 2026.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Migration Patterns of Epiphyllous Bryophyte Metapopulations in Amazonian Fragmented Landscape Inferred From Census and Genomic Data

Biotropica, Volume 57, Issue 5, September 2025.
We examined the long‐term genetic consequences of habitat fragmentation on two epiphyllous bryophyte species in experimentally fragmented Amazonian forests. Using genotyping and demographic data, we found species‐specific responses and metapopulation dynamics in relation to their mating system.

A new species of Characidium (Characiformes: Crenuchidae) from the Iguaçu National Park, Rio Iguaçu basin, Paraná, Brazil

Journal of Fish Biology, Volume 107, Issue 2, Page 454-465, August 2025.
Abstract A new species of Characidium is described from the Iguaçu National Park, Brazil. The new species can be diagnosed from the congeners by the absence of conspicuous vertical bars, blotches and spots along the sides of the body, the presence of a scaled isthmus and adipose fin, a series of scales below lateral line and the presence of a thin dark

Development of a SNP Panel for Geographic Assignment and Population Monitoring of Jaguars (Panthera onca)

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We have developed a genome‐enabled single nucleotide polymorphism (SNP) panel for use in jaguar geographic traceability, individual identification, kinship, and sexing. Our panel, named “Jag‐SNP”, comprises 459 SNPs selected from an initial pool of 13,373,949 markers based on the inter‐biome FST, followed by rigorous filtering and addition of eight sex‐

Complex temporal dynamics of insect metacommunities along a tropical elevational gradient

Ecography, Volume 2025, Issue 1, January 2025.
Unraveling the spatiotemporal dynamics of communities is critical to understand how biodiversity responds to global changes. However, this task is not trivial, as these dynamics are quite complex, and most studies are limited to few taxa at small local and temporal scales.

HotSHOT Extraction Is a Fast, Economical, and Efficient Method for Obtaining Tardigrade gDNA

Psyche: A Journal of Entomology, Volume 2025, Issue 1, 2025.
Among the main problems in obtaining genomic DNA (gDNA) from small invertebrates such as tardigrades are the low amount of gDNA obtained per specimen, as well as the complexity of steps and number of reagents used for gDNA extraction. For example, the extraction method with chelating resin is the most used as an alternative to commercial kits for ...
