LASP1, a Novel Protein in Spermatozoa and Acrosome Reaction

open access: yesMolecular Reproduction and Development, Volume 93, Issue 7, July 2026.
LASP1 is expressed in spermatozoa, binds to F‐actin, and builds up the equatorial ring structure during acrosome reaction, which is important for hyaluronan receptor surface presentation. ABSTRACT LIM and SH3 protein 1 (LASP1) is a widely expressed scaffold protein associated with actin‐rich structures. In Lasp1‐knockout mice, reproductive defects such

Coexistence, crossover and extirpation in coalescent communities and ecotones

open access: yesOikos, Volume 2026, Issue 7, July 2026.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 3, Page 306-322, July/September 2026.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Colonisation potential of the bark beetle (Taphrorychus bicolor) on beech logs and logging residues: ecological context and implications for pest management in forests

open access: yesPest Management Science, Volume 82, Issue 7, Page 6628-6637, July 2026.
Beech residues left in shaded or semi‐shaded conditions pose a substantial risk of local Taphrorychus bicolor population outbreaks. The rapid removal or placement of residues in sun‐exposed locations can help mitigate this risk. Abstract BACKGROUND The bark beetle Taphrorychus bicolor has been traditionally classified as a secondary pest of European ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1115-1141, July 2026.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.
