Assessing the levels of intraspecific admixture and interspecific hybridization in Iberian wild goats (Capra pyrenaica). [PDF]
Evol Appl, 2021 Abstract Iberian wild goats (Capra pyrenaica, also known as Iberian ibex, Spanish ibex, and Spanish wild goat) underwent strong genetic bottlenecks during the 19th and 20th centuries due to overhunting and habitat destruction. From the 1970s to 1990s, augmentation translocations were frequently carried out to restock Iberian wild goat populations (very

Conservation threats and future prospects for the freshwater fishes of Ecuador: A hotspot of Neotropical fish diversity. [PDF]
J Fish Biol, 2021 ABSTRACT Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's ...

The scope and severity of white-nose syndrome on hibernating bats in North America. [PDF]
Conserv Biol, 2021 Abstract Assessing the scope and severity of threats is necessary for evaluating impacts on populations to inform conservation planning. Quantitative threat assessment often requires monitoring programs that provide reliable data over relevant spatial and temporal scales, yet such programs can be difficult to justify until there is an apparent stressor.

PpNAC1, a main regulator of phenylalanine biosynthesis and utilization in maritime pine. [PDF]
Plant Biotechnol J, 2018 Summary The transcriptional regulation of phenylalanine metabolism is particularly important in conifers, long‐lived species that use large amounts of carbon in wood. Here, we show that the Pinus pinaster transcription factor, PpNAC1, is a main regulator of phenylalanine biosynthesis and utilization. A phylogenetic analysis classified PpNAC1 in the NST

People and Nature, Volume 5, Issue 5, Page 1512-1525, October 2023., 2023 Abstract The harvest of wild plants with medicinal uses is increasing globally, both for self‐treatment and as a source of income. The increasing demand for these remedies could lead to the over‐harvest of some species. Despite a recent surge in the number of studies analysing wild medicinal plants management, little is known about the effects of non ...

Do relaxed selection and habitat temperature facilitate biased mitogenomic introgression in a narrowly endemic fish? [PDF]
Ecol Evol, 2016 In this study, we used a combination of genetic and environmental data, to examine mitochondrial introgression in the narrowly endemic and trophically polymorphic cichlid, Herichthys minckleyi. Using extensive mitochondrial sequencing and 6220 nuclear single nucleotide polymorphisms, we show that mitochondrial introgression into H.
