1. Wednesdays 🧵thanks for your patience. Had a busy day 😐. Hope this is worth the wait. Today, we are going to talk about the Burrishoole population of Salmo salar, the mighty Atlantic salmon

2. From the outset, we are talking about Atlantic salmon today (Salmo salar) and not any of the Pacific salmon species (various Oncorhynchus sp.). 1 of these species is making in-roads into this side of the Atlantic (the PINK salmon), but that’s a whole other story 
3. Why do salmon receive so much attention, in comparison to other fish species? @SteveOrmerod put it very well:
Happy to announce that our article "Temperature effects on crop yields in heat index #insurance" with @tobi_dal and @RobertFinger1 is now online and #openaccess in @_Food_Policy. A short 🧵about the article that is available here:

#Heat drives crop yield volatility. Index #insurance can reduce the resulting financial losses suffered by farmers and support #adaptation to #climatechange. Yet, there remains a protection gap for heat risks in most of European #agriculture. (1/🧵)
We introduce a payout function into heat (weather) index insurance design that integrates a cutting-edge method to empirically estimate nonlinear temperature effects on crop yields. We apply and evaluate this novel function for German winter wheat and rapeseed producers. (2/🧵)

@wareslab: Hello! For those of you who don’t know me - I study how diversity is distributed, often using molecular markers to define that diversity and work towards knowing the function and mechanism that makes patterns of it. (2/n) #TakeOver #ReadAlong
It’s wonderful! I think of the globe and patterns of movement across it, in so many ways, and I get paid to do that. (3/n)

Hi shorebird folks! 1more4U2go! Migratory shorebirds connect. Movements, presence & phenotypes signal the state of habitats. Let's develop tracked individual migratory birds as sentinels (of connected parts) of Earth. #ornithology #globalchange @WaderStudy

Recently, 100 units of fossil energy produced 104 energy units of food, thanks soil-based processes. Now, 100 units fossil energy yield 16 food units, the 84% loss equals release of CO2 & active nitrogen threatening climate & biodiversity. #globalchange #dairy

1 #ISTC20 #Sesh2 Hi everyone! Migratory ranges emerge from individual journeys between breeding and winter sites each year. Tracking these individual journeys in space and time can help us understand how migratory ranges form and change wadertales.wordpress.com/2019/07/29/gen… #ornithology
2 #ISTC20 #Sesh2 Since the 1990s, and with an amazing network of observers (‘godwiteers’), we have marked thousands of Icelandic black-tailed godwits and tracked them on their annual journeys between Iceland and W Europe wadertales.wordpress.com/2015/10/06/the… #ornithology
3 #ISTC20 #Sesh2 The breeding and winter ranges of Icelandic godwits have expanded northwards, but have these changes involved (a) individuals shifting sites or (b) generational change, with new generations occupying different sites? besjournals.onlinelibrary.wiley.com/doi/full/10.11… #ornithology

For my MSc by research @DICE_Kent I’m deciphering crest growth in #GreatCrestedNewts at individual and population levels. 🐸🦎

Male #GCNs grow ornamental crests every year during aquatic breeding period.
As UK seasons become less distinct, #pond arrival times are less predictable.
So what is happening with #crest development?🧐

We photographed >100 individual #newts over 2 breeding periods and tracked changes in crest size + shape using #ImageJ software.
Does early arrival = Early growth peak?
Or ⬆ growth period i.e. potential mating advantage?

Thrilled to have my first paper published in @ScienceMagazine today. Thanks to my amazing co-author @foteini_pas!
We show how #Bumblebees make plants flower earlier - bumblebees are gardening!

2/17 #Bumblebees are excellent pollinators for many fruits and vegetables.
Unlike honey bees, bumblebees do not have a permanent colony. In autumn, each colony dies and only the young, mated queens hibernate, ready for spring when they start a new nest.

3/17 When the young queen emerges, she must rapidly establish a new nest. The failure rate of colonies is very high during early development, so having a succession of suitable flowers available is CRUCIAL.

To kick off 2019, science & conservation @MortonArboretum has a couple positions we’re recruiting for: (0/3)
I’m looking for a part-time person to help coordinator our #CitizenScience #phenology monitoring program, which is a partnership with @USANPN. Help us communicate with our awesome volunteers and track the life cycles of some fun trees! careers.hireology.com/themortonarbor… (1/3)
We’re also accepting applications for our summer undergrad research program. Lots of cool projects with great scientists available. More info: mortonarb.org/ctsurf (2/3)
2018 is the 61st year of long term ecological research in Burrishoole #BurrishooleLTER @MarineInst. I'm going to pin this tweet here and at the end of every month add some phenological happenings 🌿🐛📈🐟💦🦆🦉🦇🕷🍃🌼🌙🌝❄️, including our main jobs. Stay tuned 👇🏼
@MarineInst This will coincide with our monthly staff meetings (last wed of each month) so I can get everyone's observations @FishEcoEvo @elizabethtray3 @B2020project
