Water purification, moderation of extreme events, recreation. Just a few of the #ecosystemservices provided by #beavers. Our latest research: https://t.co/7IqzFJJGoh

Our new paper published on @MammRes shows #beaver-modified habitats have different species composition of small #mammals compared with control sites.

Nyt on hyvä aika torjua haitallinen #kurtturuusu ja estää sitä leviämästä luontoon. Koska kurtturuusun tunnistaminen voi olla haasteellista, teimme ohjeet sen erottamiseen. Ohjetta voi soveltaa myös ei-kukkiviin ruusuihin. #vieraslajit

Beavers benefit, eels, benefit, herons benefit. Heron doing very well from a healthy eel population (one of the UK's most endangered species) in beaver-created wetland. #beavers #RSPB #Springwatch2020 #Argyll

Those biodiversity engineers of Evo are back in the news! With data going all the way back to the 70's, the biodiversity effect of beavers is clearly visible. The mosaic of habitats created from repeated flooding is important for many organisms https://t.co/3cCmOK3RW1

– Majavan toimien myötä metsämaisemaan syntyy ainutlaatuinen kosteikkoympäristöjen kirjo: pusikkoisia tulvikkoja, niittymäisiä ympäristöjä ja tulvissa kuollutta, lahoavaa puuta, joista hyötyvät lukuisat eri eliölajit, toteaa @nummi_petri @helsinkiuni #mmtdk #metsätieteet.

Wenfei Liao löysi @helsinki ja @VantaanKaupunki kaupunkilammista 39 sukeltajakuoriaislajia. Sekä kalalliset että kalattomat lammet ovat tärkeitä kaupunkiluonnon monimuotoisuuden kannalta https://t.co/T1rabYmHwK @helsinkiuni #bytdk @HELSINKISUS @niemela_jari #monimuotoisuus

Our urban diving #beetle (#Dytiscidae) paper is now online! Do you want to know how #aquatic insect diversity change along an #urban gradient? Are you curious about how predatory #fish affects #dytiscid species composition? Find out in our paper via link: https://t.co/MUFAJ900Ga

Interesting new study by the @helsinkiuni reinforcing understanding of many benefits that beavers provide as ecosystem engineers within diverse landscapes! @nummi_petri https://t.co/IgXl1VtNb9 and original paper -> https://t.co/Hvnl2TUod9

Beavers aid the survival of the #pinemarten, #eurasianotter and #commonteal – all protected species in the UK!
Thanks to @nummi_petri and colleagues for the valuable research!

Beavers not only influence biodiversity of insects and birds, but also mammals too! New research from Evo shows that moose, otters and weasels visit beaver ponds more than control ponds. https://t.co/swoqWduXfI
