Diversity and Distributions, Volume 32, Issue 5, May 2026.ABSTRACT Aim Species Distribution Models (SDMs) are widely used in conservation planning, invasive species management and global change assessments. Their reliability depends on both presence and absence data, yet biodiversity databases are dominated by presence records, while true absences are rarely collected and geographically restricted.

Allozyme diversity of european freshwater crayfish of the geniusAustropotamobius [PDF]
Bulletin Français de la Pêche et de la Pisciculture, 1997 Data are reported on genetic variation at 30 enzyme loci in Austropotamobius crayfish from France, England, Italy, Spain, and the Balkans. Three population groups were detected, corresponding to A. torrentium, A. pallipes and A. italicus (sensu KARAMAN, 1962). Reproductive isolation between these three taxa was demonstrated in the field.

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...

Sex‐Specific Control and Incomplete Matings: Sperm Removal Behavior in a Bush Cricket Species
Ethology, Volume 132, Issue 3, Page 194-203, March 2026.In this study, we investigated which sex influences the duration of sperm removal behaviour (SRB) in the ornate bush cricket, Metaplastes ornatus. Female traits showed a weak effect on SRB duration, and lighter females mated more frequently. Frequent unsuccessful mating terminations shortened SRB indicating high level of sexual conflict.
