The paper assesses progress toward global biodiversity targets on islands, finding insufficient progress and major gaps in indicators and objectives.

The paper investigates environmental and geographic factors influencing plant diversity in South American coastal lomas, finding an inverse latitudinal gradient shaped by climate, topography, and human impact.

The paper quantifies global shifts in plant functional trait composition due to human introductions, finding convergence toward smaller, more acquisitive, and shorter-lived assemblages.

This study presents the first global checklist of island bees, revealing high diversity and endemism, with patterns influenced by island size, isolation, and biome.

This study shows non-native species disrupt global plant biogeography by reducing distinct floristic realms and subrealms, with environmental factors remaining key in structuring plant distributions.

This study examines the global biogeography of ferns with chlorophyllous spores, finding that their distribution is influenced by both environmental factors and phylogenetic clustering.

The paper investigates the factors behind low plant diversity in tropical Africa using ferns, finding that Paleogene extinctions and Neogene dispersals shaped current diversity.

This paper combines crowdsourced biodiversity data with Earth observation to model plant traits at high resolution, achieving strong predictive power and improving spatial coverage for global trait mapping.

A-Islands is a curated dataset of plant species occurrences on Australian islands, enabling biodiversity research and ecological monitoring across diverse island environments.

The paper tests passive and active restoration strategies in oil palm landscapes, showing that planted tree diversity enhances natural regeneration and multifaceted diversity recovery.

The paper assesses how stand structure and forest cover affect biodiversity and ecosystem functions in Madagascar's tropical landscapes, finding that complex structures enhance endemic species richness and functions.
