Phylotranscriptomics Allows Distinguishing Major Gene Flow Events from Incomplete Lineage Sorting in Rapidly Diversifying Mimetic Orchids (Genus Ophrys)

This study uses phylotranscriptomics to distinguish between gene flow and incomplete lineage sorting in Ophrys orchids, revealing ancient adaptive gene flow events.

Climbing invasions or climatic refugees: how many and to which extent non-native plant species could reach the top of the Pyrenees mountains under climate change?

This study projects how many non-native plant species in the Pyrenees will shift upslope under climate change and how many will decline, finding 57% will not benefit from warming.

Life-history traits may buffer genetic erosion under isolation in mountain sky-island systems

The paper investigates genetic resilience in Xatartia scabra under isolation, finding moderate diversity and low inbreeding despite small population sizes and strong isolation.

Unravelling the bottom-up and top-down control of a worldwide chestnut tree pest invader through integrative ecological genomics

The paper identifies the relative impacts of host trees, resistance pathways, and natural enemies on the invasion potential of a chestnut tree pest using ecological and genomic analyses.

Non-invasive eDNA reveals the ecological and genetic status of the Western Capercaillie (Tetrao urogallus aquitanicus) in the Eastern Pyrenees

The paper uses non-invasive eDNA from fecal samples to assess the ecological and genetic status of the Western Capercaillie in the Pyrenees, finding low genetic diversity and inbreeding.

A cryptic hybrid zone reveals the genomic basis of flower colour variation in a plant with a large and complex genome

The paper identifies candidate loci for flower color variation in Pedicularis comosa using a multi-omic approach, revealing the involvement of anthocyanin pathway genes.

Projecting spatiotemporal bioclimatic niche dynamics of endemic Pyrenean plant species under climate change: how much will we lose?

This study projects climate change impacts on Pyrenean endemic plant species by 2100, finding 69% will lose over 75% of their bioclimatic niche under high-emission scenarios.

Contrasting patterns of differentiation among three taxa of the rapidly diversifying orchid genus Ophrys sect. Insectifera (Orchidaceae) where their range overlap

The paper uses population genomic approaches to analyze genetic differentiation among three orchid taxa in overlapping ranges, finding distinct genetic clusters but weak differentiation in Iberian populations.

Specialization into Host Sea Anemones Impacted Clownfish Demographic Responses to Pleistocene Sea Level Changes

The paper examines how clownfish demographic responses to Pleistocene sea level changes are influenced by their host specialization, revealing resilience in generalists and bottlenecks in specialists.

First draft genome assembly of an iconic clownfish species (Amphiprion frenatus)

The paper presents the first draft genome assembly of the tomato clownfish (Amphiprion frenatus), providing a resource for studying its life history traits and adaptive radiation.
