A‐Islands: A Vascular Plant Dataset for Biodiversity Research and Species Monitoring on Australian Continental Islands

Journal of Vegetation Science, Journal Year: 2025, Volume and Issue: 36(2)

Published: March 1, 2025

ABSTRACT Aims Australia's coastline is fringed by more than 8000 continental islands. These islands feature a diverse array of landforms, rock and soil types geological origins. Some these are among the least invaded, most pristine habitats in Australia support high plant diversity. Here, we present new Australia‐wide curated dataset for species occurrences on Results Combining information from 1349 lists floras, A‐Islands includes data > 6500 844 ranging size 18 m 2 to 4400 km , exhibiting different degrees isolation mainland, spanning all major Australian climate zones. Of these, 251 have been repeatedly sampled up 11 times, making it possible investigate temporal compositional change. open access will be continuously updated. Its simple structure, consisting three comma‐separated files allows easy integration with other global plant‐occurrence databases can serve as repository island research Australia. Conclusions Knowing which occur provide opportunities future research, including studying changes biodiversity turnover within archipelagos, tests classical biogeography theory, baseline ecological monitoring conservation.

EGCop: An Expert‐Curated Occurrence Dataset of European Groundwater‐Dwelling Copepods (Crustacea: Copepoda)

Global Ecology and Biogeography, Journal Year: 2025, Volume and Issue: 34(1)

Published: Jan. 1, 2025

ABSTRACT Motivation Subterranean biodiversity is increasingly threatened by multiple intertwined anthropogenic impacts, including habitat loss, pollution, overexploitation of resources, biological invasions and climate change. Worryingly, subterranean still poorly represented in conservation agendas, also due to persisting gaps our knowledge the organisms thriving often‐secluded difficult‐to‐access ecosystems. This even more apparent for small‐sized (body size < 1 mm) groundwater‐dwelling metazoans, among which copepods (Crustacea: Copepoda) represent dominant group terms both species richness biomass. We present a dataset 6986 occurrence records 588 species/subspecies European obligate copepods. curated all make their taxonomy consistent with current systematics Copepoda, while assessing uncertainty geographic coordinates coupling in‐depth web literature searches GIS analyses. suggest data provided can be used explore range eco‐evolutionary questions—from drivers distribution groundwater fauna assembly communities—as well as prompt more. Main Types Variables Contained Occurrence copepods, details about specimen taxonomy, source record, locality type. Spatial Location Grain Geographical Europe (including western Russian Federation), along Turkey Georgia. were assigned projected (EPSG:3035) at 100 m resolution but varying spatial uncertainty. Time Period 1907–2017. Major Taxa Level Measurement Crustacea: Copepoda. Most have species‐level identification, some them are identified subspecies level.

Climatic and biogeographic factors show contrasted effects on continental and volcanic ISARs

Community Ecology, Journal Year: 2024, Volume and Issue: unknown

Abstract Aim The study of islands biotas is fundamental to understand biodiversity patterns and process, both on evolutionary ecological time scales. This explores the influence biogeographic climatic factors island species–area relationships (ISARs) in volcanic continental islands, aiming detect differences slopes intercepts between these origins. Methods Data from 5049 vegetation plots 58 Central Mediterranean Sea were collected various sources. Islands categorized as or based their geological origin. area, isolation, maximum elevation, eccentricity, mean annual temperature precipitation calculated for each island. By using a moving window, we created groups ISARs fitted group Arrhenius power functions. Linear models permutation test employed examine how ISAR model parameters varied with above-mentioned variables. Results While intercept values did not differ origins, showed higher than islands. Whereas increasing isolation increased groups, it decreased ones. Increasing groups. eccentricity slope while it. elevation Main conclusions Our provides evidence about importance origin determining observed patterns. Biogeographic are pivotal shaping species richness exerting varying influences
