Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Ocean Romance: Japanese Treefrogs Exploit Coastal Pools for Breeding Under Salinity and Habitat Constraints

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Topographical features, including elevation and the distance of pools from the coastline and forest, influenced breeding‐site use in coastal landscapes. Pool characteristics such as area and depth, together with abiotic conditions particularly salinity, as well as dissolved oxygen, and temperature, further shaped breeding‐site suitability and patterns ...

Microplastic as a Vector of Metformin: Influence of Aging on Adsorption and Desorption Properties

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT This study investigated how ultraviolet aging alters the physicochemical properties of polyethylene microplastics and affects the adsorption and desorption of metformin in water. Virgin polyethylene microspheres (PMP) were irradiated for 30 (MP30) and 120 (MP120) days to simulate environmental weathering. Aging caused evident surface cracking,

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 235-248, June 2026.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Analysis of Nonstationary Change of Annual Maximum Level Records in the Yangtze River Estuary

open access: yesAdvances in Meteorology, 2016
Under the impact of climate change and human activities, the stationarity of hydrometeorological extreme value series has been losing in many regions, which makes occurrence rules of hydrometeorological extreme events more complicated. In this study, the

Accounting for Spatial Variation in Trophic Processes of Fishes in Large Lakes: An Ecoregion Approach

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT For more than 50 years, Lake Ontario has experienced continuous ecological change. The causes and consequences of these changes are only partially understood. Existing monitoring and management programs collect lake‐wide data and provide results and recommendations on perceived lake‐wide processes, potentially overlooking regionally important ...
