Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Microbial and bryospheric photosynthesis of boreal peatlands have peatland‐type‐specific responses to long‐term drying

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1336-1350, November 2025.
Summary The impacts of drying on bryospheric photosynthesis are poorly understood. Utilising a 20‐yr‐long experiment, we quantified the effects of long‐term water level drawdown (WLD) on links between bryospheric photosynthesis, microbial community composition, decomposition, and environmental variables.

Spatiotemporal Variations in Surface Air 7Be Concentrations Over the Antarctic Regions of the Indian Sector

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract This study examined spatiotemporal variations in Beryllium‐7 (7Be) concentrations measured in surface air in high‐latitude regions of the Indian sector of the Southern Ocean, including two Japanese coastal stations. The sites included Syowa Station (69°00′S, 39°35′E) and site S17 (69°02′S, 40°05′E) on the coastal Antarctic ice sheet ...
