Linking range wide energetic trade-offs to breeding performance in a long-distance migrant

Camilo Carneiro, Tómas Gunnarsson, Veronica Méndez, Amadeu Soares & Jose Alves
Understanding how individual trade-offs and carry-over effects along the annual cycle influence fitness is fundamental to unravel population dynamics, but such data is particularly challenging to collect in long-distance migrants. Here, with a full annual cycle perspective of Icelandic whimbrels Numenius phaeopus islandicus, we investigate trade-offs across the entire distribution, assessing migration costs and wintering energetic balance experienced throughout the wintering range (from temperate to tropical regions), and link these to breeding parameters for two...

Data for: Parasitoids indicate major climate-induced shifts in Arctic communities

Tuomas Kankaanpää, Eero Vesterinen, Bess Hardwick, Niels Martin Martin Schmidt, Tommi Andersson, Paul Eric Aspholm, Isabel Barrio, Niklas Beckers, Joël Bêty, Tone Birkemoe, Melissa DeSiervo, Katherine Drotos, Dorothee Ehrich, Olivier Gilg, Vladimir Gilg, Nils Hein, Toke Høye, Kristian Jakobsen, Camille Jodouin, Jesse Jorna, Mikhail Kozlov, Jean-Claude Kresse, Don-Jean Leandri-Breton, Nicolas Lecomte, Maia Olsen … & Tomas Roslin
Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a wide-spread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e. parasitoid use of herbivorous Lepidoptera versus pollinating Diptera)...

Könnun á kosningaþátttöku í sveitarstjórnarkosningum 2014

, &
Í sveitarstjórnarkosningunum í maí árið 2014 var kjörsókn í landinu minni en nokkru sinni fyrr. Á landinu öllu varð heildarkjörsóknin 66,5% og í þremur stærstu sveitarfélögum landsins var hún einungis um 60 prósent. Óhætt er að fullyrða að fáa hefði órað fyrir jafn mikilli minnkun kjörsóknar á jafn skömmum tíma. Að vísu hafði verið leitt að því líkum að hina dræmu kjörsókn í kosningunum árið 2010 mætti að einhverju leyti rekja til áhrifa frá bankahruninu...

Plant DNA metabarcoding record from a sediment core from Lake Naleng, southeastern Tibetan Plateau

Sisi Liu, Stefan Kruse, Dirk Scherler, Richard H. Ree, Heike H. Zimmermann, Kathleen R. Stoof-Leichsenring, Laura S. Epp, Steffen Mischke & Ulrike Herzschuh
Here, we provide the raw plant DNA metabarcoding data archived in Lake Naleng sediment core spanning the late-glacial to the present (17,700 to 0 cal yr BP). Lake Naleng (31.10° N, 99.7°5 E, 4200 above sea level) is situated in a glacially-formed basin on the southeastern Tibetan Plateau. It is an alpine freshwater lake with a maximum water depth of 36.7 m, an open surface area of 1.7 km2, a specific conductivity of 0.045 mS/cm,...

A supergene underlies linked variation in color and morphology in a Holarctic songbird

Erik Funk, Nicholas Mason, Snæbjörn Pálsson, Tomáš Albrecht, Jeff Johnson & Scott Taylor
The genetic architecture of a phenotype can have considerable effects on the evolution of a trait or species. Characterizing genetic architecture provides insight into the complexity of a given phenotype and, potentially, the role of the phenotype in evolutionary processes like speciation. We use genome sequences to investigate the genetic basis of phenotypic variation in redpoll finches (Acanthis spp.). We demonstrate that variation in redpoll phenotype is broadly controlled by a ~55-Mb chromosomal inversion. Within...

Þátttaka almennings í sóttvarnaraðgerðum vegna COVID-19 faraldursins í apríl 2020 til mars 2021

Félagsvísindastofnun Háskóla Íslands hefur í samstarfi við fræðafólk á Félagsvísindasviði Háskóla Íslands kannað þátttöku og afstöðu Íslendinga til aðgerða almannavarna til að hefta útbreiðslu COVID-19. Könnun var send daglega til 200-1000 meðlima netpanels Félagsvísindastofnunar á meðan faraldurinn stóð yfir. Markmiðið var að kortleggja hegðun og afstöðu almennings með tilliti til aðgerða almannavarna og greina hvernig afstaða fólks til aðgerðanna breytist yfir tíma. Gagnasafn þetta tekur til tímabilsins 1. apríl 2020 til 26. mars 2021 og...
