Ecosphere, Volume 15, Issue 8, August 2024.Abstract A characteristic feature of Earth's drylands is the patchy nature of the vegetation, often referred to as a two‐phase mosaic landscape, comprised of a homogenous matrix containing distinctive vegetated patches. The latter are considered vital for ecosystem functioning as they provide refuge to biota from unsuitable conditions.

The origin and speciation of orchids
New Phytologist, Volume 242, Issue 2, Page 700-716, April 2024.Summary Orchids constitute one of the most spectacular radiations of flowering plants. However, their origin, spread across the globe, and hotspots of speciation remain uncertain due to the lack of an up‐to‐date phylogeographic analysis. We present a new Orchidaceae phylogeny based on combined high‐throughput and Sanger sequencing data, covering all ...

Age of Eucalyptus plantations differentially affects assemblages of surface‐active arthropods
African Journal of Ecology, Volume 62, Issue 1, January 2024.Abstract Microhabitats and environmental conditions in eucalypts vary depending on the growth phase. Response of surface‐active arthropods to eucalypt growth phases is unclear; yet, it can be an important contribution in forest management. Thus, we investigated the response of surface‐active arthropods to three eucalypt age groups.
