Environmentally Grounded Pseudo‐Absence Sampling for Species Distribution Models: A Language Guided Framework

open access: yesDiversity 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.

Use of three forms of decapsulated Artemia cysts as food for juvenile noble crayfish (Astacus astacus)

open access: yesCzech Journal of Animal Science, 2011
Summerling (six-month old) noble crayfish fed two forms of freshly decapsulated (FD) Artemia cysts more than tripled their weight during a 75-day experiment under controlled conditions. Final survival rates were at the level of 90%.
