Urban dytiscid research findings on @yliopistolehti.bsky.social 6-year data show #dytiscid species richness and abundance were declining in #urban ponds, indicating the negative effects of #urbanisation can be long-term 😕 @geohelsinkiuni.bsky.social

Large water beetle called Colymbetes fuscus attracted to a moth trap

Attractively marked brown moth called a March Moth

Tiny brown Micro-moth called a Spring Harbinger

Fluffy grey moth called a Pale Brindled Beauty

The night wasn't quite as good as forecast
3 moths and a beetle in the traps
Pale Brindled Beauty, March Moth, Tortricodes alternella and a diving beetle Colymbetes fuscus

Temporal Alpha and Beta Diversity of Diving Beetles (Coleoptera: Dytiscidae) Reveals Biotic Heterogenisation in Urban Ponds Urbanisation has led to decreasing quantity and quality of both terrestrial and aquatic habitats, resulting in biodiversity loss in urban ecosystems. Current research has focused on spatial patter...

Our new article by @wenfeiliao.bsky.social & #JanneSoininen shows #urban #dytiscid assemblages experienced #biotic #heterogenisation. Clustered #ponds are more likely to maintain stable populations due to immigration than isolated ponds. doi.org/10.1111/fwb....
