Patterns of species diversity in different spatial scales and spatial heterogeneity on beta diversity [PDF]

Acta Botânica Brasílica, 2019
Patterns of species diversity are essential to understand community structure. We aimed to determine species diversity and patterns of beta diversity in different spatial scales. We sampled three thousand individuals between the coordinates 22°10'S to 22°

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

Climate and Volcanic Activity Modulate Area–Distance Effects on Plant Diversity Along the Temperate–Subarctic Island Volcanic Arc

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aims To evaluate how equilibrium (ETIB) and niche‐based (NTIB) island‐biogeography frameworks jointly explain taxonomic and phylogenetic diversity in a temperate–subarctic, volcanically active archipelago. Location Kuril Islands, northwestern Pacific (44°–50° N). Time Period Present. Taxon Vascular plants.

Geobotany Revisited – A Glimpse at the Blooming and Influential Discipline With Its Strong Roots in the Beauty of Nature and the Pragmatic Need of Its Protection

Acta Societatis Botanicorum Poloniae, 2022
The dreams of Humboldt and many of his successors have not yet come true. Despite the great achievements of the last century, we still do not know the total number of vegetation types or the difference in the patterns of the distribution of diversity ...

The role of microclimate in supporting peatlands as climate‐change refugia: A Central European perspective

Conservation Science and Practice, Volume 8, Issue 1, January 2026.
Some peatlands in Central Europe serve as continuous refugia for glacial species, as shown by paleoecological data. However, the ecosystem mechanisms behind this are not well understood. Microclimate plays a key role, and understanding the factors shaping it is crucial for managing peatlands as climate‐change refugia.

Here, There and Everywhere: Widespread Non‐Native Plants in the World's Urban Ecosystems

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim To (a) produce a list of the most widespread naturalised non‐native plant species across cities of the world; (b) explore whether cities on different continents are invaded by the same group of widespread naturalised species; and (c) elucidate the origins of the most widespread naturalised urban species. Location Global.
