Genomic erosion in a demographically recovered bird species during conservation rescue. [PDF]

Conserv Biol, 2022
Abstract The pink pigeon (Nesoenas mayeri) is an endemic species of Mauritius that has made a remarkable recovery after a severe population bottleneck in the 1970s to early 1990s. Prior to this bottleneck, an ex situ population was established from which captive‐bred individuals were released into free‐living subpopulations to increase population size ...

Genetic origins and climate-induced erosion in economically important Asian walnuts. [PDF]

Conserv Biol
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

Hybridization patterns between two marine snails, Littorina fabalis and L. obtusata. [PDF]

Ecol Evol, 2020
The flat periwinkles, Littorina obtusata and L. fabalis (Gastropoda), comprise an interesting system to study how reproductive barriers evolve during (ecological) speciation with gene flow. In this study, we characterized the patterns of hybridization between the two intertidal sister species across multiple populations in the Iberian Peninsula ...

Restricted Dispersal in the Late Successional Forest Tree Species <i>Nothofagus Pumilio</i>: Consequences Under Global Change. [PDF]

Ecol Evol
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.

Preliminary insights of the genetic diversity and invasion pathways of Cedrela odorata in the Galapagos Islands, Ecuador. [PDF]

Ecol Evol
Cedrela odorata is the second most invasive tree species in the Galapagos Islands. Using nine microsatellite markers, we found that the genetic diversity of C. odorata in Galapagos is lower (He = 0.55) than in mainland Ecuador (He = 0.81). Our preliminary findings suggest multiple introduction events and that the origin of C. odorata in Galapagos could

An integrative approach to assess non‐native iguana presence on Saba and Montserrat: Are we losing all native Iguana populations in the Lesser Antilles?

Animal Conservation, Volume 26, Issue 6, Page 813-825, December 2023., 2023
Iguanas are native to all Lesser Antillean islands, where they are among the most important keystone species within the threatened Caribbean dry‐forest biome. However, several populations have already become extinct and all but two remaining island populations are under direct threat of hybridization with non‐native iguanas.

Combining otolith chemistry and genetics to infer the population structure of yellow snapper Lutjanus argentiventris

Ecosphere, Volume 14, Issue 10, October 2023., 2023
Abstract Developing a metapopulation framework contributes to the understanding of spatial processes and structures in populations, providing basic information for conservation biology. However, the extent to which the metapopulation structure differs geographically and across life history stages is unexplored for most fishes.

Genetic diversity and IUCN Red List status

Conservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool for conservation assessment. The IUCN uses information about a species’ range, population size, habitat quality and fragmentation levels, and trends in abundance to assess extinction risk.
