A massive thank you to @CorncrakeLife for the great week of crex conservation!
From May 01st, we have none other than @RuthFCarden taking over the account!
Ruth is a (palaeo)zoologist, zooarchaeologist and Quaternary faunal specialist working in Ireland on commercial and academic projects for the past 20+ years.
Ruth is a part time Research Scientist with the School of Archaeology, UCD on the Irish Cave Bones Project.
She has wide-ranging commercial/research interests driven by a multidisciplinary approach involving key themes including zoology, palaeoecology, GIS spatial modelling, zooarchaeology & dynamics between human-animal relationships, & palaeoenvironment during the past 50,000 years
Stay tuned for a great week explaining the where, what, why and who of Irish ecology!

Day1: Intro 🧵
Thanks to @IrelandsEnviro for inviting me on to chat to ye all about our research & work on #IrishCaveBones, cave research, past ecosystems & humans/animals in Ireland during past c.50,000 years! so we start-some background first, why we started and who we are. 1/n
2/n Back in 2006/7, I was researching the origins of red deer in Ireland, along with some others. I approached @NMIreland Natural History Division to access animal bones that had been excavated from Irish caves in late 1800s to mid 1900s, seeking red deer bones if present.
3/n I did indeed find ancient red deer bones and antler (as we wanted to compare ancient DNA with modern Irish populations to determine if any were descended from ancient populations), but also found bones that were listed as red deer, but were not - pig, sheep, horse!
1/Friday we made it! We saw briefly/incompletely how #pollen#beetles preserved in #peat can shed light on long term #ecological change. There are other 'proxies' + the #peatland#archaeological record, esp rich in 🇮🇪, a remarkable 'archive' of past people/environments/climate
2/Dr Eileen Reilly (photo 1, r) passed away too young. Her #Palaeoentomological work was groundbreaking. Demonstrated presence of beetles in #prehistory now extinct/rare in 🇮🇪 many associated with wood/trees (Saproxylic), 'Urwald relict' group (see table!)
3/E.g: photos 1+2 #Archaeological excavations, Lisheen Bog, Co.Tipp. Samples from Bronze Age oak wood plank trackway, contained remains of Prostomis mandibularis+other bugs. Primary #woodland present in this period despite clearance/farming.
1/Hi all! This afternoon we look (selectively) at what pollen records, tell us about long term changes, from the end of the last Glaciation. How has climate, humans+related processes shaped the 🇮🇪 vegetation over thousands of years? (Nick Miller, From Cogan's Shed, 2004)
2/Difficult to summarise 1000s yrs in tweets! Image by Gill Plunkett @QUBelfast does good jobNB. highly generalised, much spatial variation across country; Key points: development of woodland as climate warms start of #Holocene hazel dominant, oak, elm, later alder, how dense?
3/Closed canopy? But NB1 Concept of 'Climax' woodland largely discredited; : 'openess' is under-represented in #pollen records! NB2; #ClimateChange driving some changes; other processes inc. soil development. When does human activity impact? Now that's a good qu!
1/7 –Hi I’m Jo - I’m an ecologist specialising in plants and bryophytes My aim is to introduce you to the world of bryophytes (mosses, liverworts and hornworts). See thread for today’s introduction to this group.
2/7 Here is an example of a hornwort (Phaeoceros species) and a typical habitat where it is found (a soil bank). Hornworts have unusual reproductive structures ‘green horns’, but the main plant is flat and green.
3/7 The next group is liverworts. Thalloid liverworts don’t have stems and leaves. Here is Great Scented Liverwort Conocephalum conicum. It has a pattern of lines and dots on its surface and is scented.
It's Sunday morning so I am going to keep it light and easy - with a 🧵of interesting videos that you can watch at your leisure😎📺🌊

#RealVoices
Is a series of short films about fishers here in 🇮🇪 and their connection to the sea.
John Brittain, a Galway sea angler tells us how he believes MPAs could lead to better living for coastal communities & a chance to protect biodiversity. 2/
#BlueCarbon
Is the organic carbon captured & stored by the world's oceanic & coastal ecosystems (think seagrasses, macroalgae, mangroves, salt marshes etc.) making the 🌊our biggest ally for mitigating #ClimateChange 💪🌍🌎🌏 3/
