Stakeholders’ perspectives on barriers and pathways toward the diversification of planted forestsNARA Subscribed
Mixed planted forests (MPFs) are often considered more resilient to climate change and provide greater environmental benefits than monocultures. Yet, monocultures dominate tree plantation systems globally. Here, we examined the motivations, barriers, and opportunities that affect forest stakeholders’ adoption of MPFs across four countries with strong yet distinct forest sectors: Brazil, France, Portugal, and Sweden. We conduct...
Population‐specific bycatch risks in two vulnerable anadromous clupeids: Insights from otolith microchemistryNARA Subscribed
Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...
The impact of the 2024 coral bleaching event on corals at a remote atoll in the Tuamotu Archipelago, French PolynesiaNARA Subscribed
Coral reefs are under severe threat from global warming, particularly due to the increasing frequency of mass coral bleaching events. This study documents the effects of the fourth global coral bleaching event on corals of Tahanea, a remote uninhabited French Polynesian atoll over a 10-month period. Coral surveys (transects and tracking of individual colonies) and temperature monitoring were conducted by one in situ observer....
The bastard grunt Pomadasys incisus (Bowdich, 1825), an Atlantic teleost, has recently been recorded at multiple sites along the French Ligurian Sea. Three juveniles were captured in Villepey Lagoon, while several groups of sub‐adult and adult individuals were observed at Cagnes‐sur‐Mer and Monaco between 2020 and 2024. These records indicate a shift from occasional sightings to a perennial presence, likely linked to ongoing M...
Bridging the Energy Balance Gap in Eddy‐Covariance Measurements: Insights From Standardized Network DataNARA Subscribed
The lack of energy balance closure in Eddy‐Covariance (EC) measurements is a well‐known, still unresolved challenge in micrometeorology, with energy balance closure (EBC) rates typically ranging between 60% and 80%. While numerous hypotheses have been proposed to explain this imbalance, the relative contributions of neglected energy storage terms, data quality and flux processing options remain insufficiently disentangled. Usi...
There is growing interest in deploying insect traps in forest canopies for ecological research, invasive species surveillance, and biodiversity monitoring. However, forest canopies also harbor a diverse and abundant bat community, which may be incidentally trapped and killed by these devices. In this study, we investigated the impact of flight interception traps and multi-funnel traps deployed in oak canopies on incidental bat...
Through genomic phylogeography, previously unrecognised biodiversity can be revealed. The alpine newt serves as a case in point: this taxon carries highly distinct mtDNA clades and has a severely fragmented range. We obtain genome‐wide data with target enrichment by sequence capture to delineate cryptic species and disentangle their phylogenetic relationships. Furthermore, we explore potential niche divergence and glaciation‐d...
