Wee Map I did of the Isles with all their native place names. It's an update from the previous one, with more places included. You can buy it here etsy.com/ie/listing/185…

#Whales that prefer #zooplankton over fish have wider nostril spacing, which may better-equip them to sniff-out zooplankton. Read "Morphology of nares associated with stereo-olfaction in baleen whales" - ow.ly/QMI850Qwg2I #BiologyLetters #sensoryecology #chemicalecology

@notsadgirlhours Fantastic congratulations Róisín!

I am extremely happy to share my first paper (‼️), a joint effort between my PhD project at @MfrcATU and mesopelagic research at the @MarineInst If you want to know more about how #eDNA 🧬 can help us study mesopelagic fish 🐟, give it a read! doi.org/10.1093/icesjm…

Atlantic bluefin tuna migrations! New paper with @FishySounds, @Thunnus, @AndreasSundelof, @SeanT1979 et al.. in @RSocPublishing OA: doi.org/10.1098/rspb.2…

During a recent wildlife survey, thanks to the @IrishAirCorps & @NPWSIreland captured an awe-inspiring moment: a majestic fin whale with playful pod of dolphins. This beautiful scene highlights the richness of marine life along our coasts that we continue to monitor and protect.

What can we learn from wild mammal carcasses? Our new global review provides key insights into host-pathogen relationships, offering recommendations for using ELISA to detect pathogen antibodies in carcasses 🦌🦠 #WildlifeHealth #Seroprevalence #Epidemiology

Excited to see our paper published, led by the talented Ingvild Ytterhus Utengen @AkvaplanNiva @UiTNorgesarktis! Here we investigated humpback whale behaviour during their seasonal stopovers and classified their tracks into five distinct movement modes🐋tinyurl.com/ye7nxra6

A new study on sperm whales off the coast of Ireland has found females and their calves are swimming in higher latitudes than before rte.ie/news/2024/0922…

@whale_nerd One female stranded in Donegal in 2022 was raked on the left pectoral, dorsal and tail stock that looked like killers too. They don't seem to be bothered by the killers in the Azores and it seems some of the rakes there on females / youngsters might be caused by their own kin

Revisiting old pictures of sperm whales off Western Sahara and noticed that one has what looks like killer whale rakes on both sides of the flukes... lucky escape!

A commercial film company was fined $30,000 for illegally using a drone to film Northern Resident #KillerWhales near #VancouverIsland. The noise and presence of aircraft, including drones, can disturb wildlife both in the water or on land. ow.ly/BGuN50T1o40
