Large‐flowered stapeliad Edithcolea grandis (Apocynaceae: Asclepiadoideae) is pollinated by dung‐ and blood‐feeding African face flies (Muscidae: Musca xanthomelas)

open access: yesTAXON, Volume 75, Issue 5, October 2026.
Abstract The more than 360 species of stem‐succulent stapeliads in the tribe Ceropegieae represent a perfect example for species radiation and diversification in response to pollination by flies. In the majority of species, the myiophilous flowers have visual and olfactory characteristics that suggest carrion or dung mimicry.

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...
