Estimating wild bee population size with validated distance sampling

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 469-483, May 2026.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

The Biology, Ecology, Distribution and Management of Two Globally Invasive Weeds: Calotropis procera (Calotrope) and Calotropis gigantea (Giant Calotrope)

open access: yesWeed Research, Volume 66, Issue 3, May/June 2026.
ABSTRACT Calotropis procera and C. gigantea are emerging as globally invasive plants that can significantly alter ecosystems in areas where they have escaped from attended cultivation. Without effective management, these species can form dense monospecific stands, resulting in severe economic, environmental and social impacts.
