Future seasonal changes in habitat for Arctic whales during predicted ocean warming

Philippine Chambault, Kit M Kovacs, Christian Lydersen, Olga Shpak, Jonas Teilmann, Christoffer M. Albertsen & Mads Peter Heide-Jørgensen
Ocean warming is causing shifts in the distributions of marine species, but the location of suitable habitats in the future is unknown, especially in remote regions such as the Arctic. Using satellite tracking data from a 28-year long period, covering all three endemic Arctic cetaceans (227 individuals) in the Atlantic sector of the Arctic, together with climate models under two emission scenarios, species distributions were projected to assess responses of these whales to climate change...

Geolocator tagging of east Siberian bluethroats

Staffan Bensch, Mikkel Willemoes, Stepan Ivanov, Sergey Vartanyan, Kristaps Sokolovskis & Diana Solovyeva
Many long-distance migratory bird species seem to retain the winter quarters their ancestors used during the last glacial maximum. Post-glacial colonization following the retreat of the ice sheets have then resulted in apparent suboptimal migration routes, since the expanding populations have failed to use more nearby, alternative and climatically suitable, wintering areas. The bluethroat subspecies Cyanecula svecica svecia occurs in the northern areas of the Palearctic from the Atlantic to Alaska. Because it is monotypic...

Quantitative assessment of the terrain transformation in proglacial areas (the Djankuat River catchment case study, Caucuses)

Andrei Kedich
Proglacial areas are extremely unstable and characterized by highly intensive geomorphic processes. In this study, we consider a typical proglacial area on the Caucuses – Djankuat river catchment. This research presents the first results for the complex monitoring of exogenic geomorphic process rates within the selected catchment. A repeated UAV survey for selected sites conducted in September 2019 and in August 2020 was the primary method. Also, high-resolution DEMs derived from stereo satellite images and...

Data from: Decipher soil organic carbon dynamics and driving forces across China using machine learning

Huiwen Li, Yiping Wu, Shuguang Liu, Jingfeng Xiao, Wenzhi Zhao, Ji Chen, Georgii Alexandrov & Yue Cao
The dynamics of soil organic carbon (SOC) play a critical role in modulating global warming. However, the long-term spatiotemporal changes of SOC at large scale and the impacts of driving forces remain unclear. In this study, we investigated the dynamics of SOC in different soil layers across China through the 1980s to 2010s using a machine learning approach and quantified the impacts of the key factors based on factorial simulation experiments. Our results showed that...

Circum-Arctic distribution of chemical anti-herbivore compounds arctic shrubs

Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top-down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the circum-Arctic variation in defence compounds is explained by taxa or defence functional groups (resinous/non-resinous). We measured circum-Arctic...

Relict permafrost features identification in landscape and deposits of Borisoglebsk Upland, Central European Russia

Ekaterina V. Garankina , Vasily A. Lobkov , Ilya G. Shorkunov & Vladimir R. Belyaev
Relict permafrost features (RPF) indicated by specific patterns of soil, sedimentary and landform structure are characteristic of Central Russian Plain watersheds. Paleocryogenic polygonal networks appear in a pattern of semi-regular spots, blocks and polygons on the surface usually associated with pseudomorphs of ice wedges or sand casts in correlated deposits. This research aimed at distinguishing RPF in sedimentary structure and its correlation with the modern and paleolandscape structure of 3 ha watershed area exposed in...

Genomic analyses show extremely perilous conservation status of African and Asiatic cheetahs (Acinonyx jubatus)

Stefan Prost, Ana Paula Machado, Julia Zumbroich, Lisa Preier, Sarita Mahtani-Williams, René Meißner, Katerina Guschanski, Jaelle C. Braeley, Carlos Rodriguez Fernandes, Paul Vercammen, Luke T. B. Hunter, Alexei V. Abramov, Martin Plasil, Petr Horin, Lena Godsall-Botriell, Paul Bottriell, Desire Lee Dalton, Antoinette Kotze & Pamela Burger
We live in a world characterised by biodiversity loss and global environmental change. The extinction of large carnivores can have ramifying effects on ecosystems like an uncontrolled increase in wild herbivores, which in turn can have knock-on impacts on vegetation regeneration and communities. Cheetahs (Acinonyx jubatus) serve important ecosystem functions as apex predators; yet, they are quickly heading towards an uncertain future. Threatened by habitat loss, human-wildlife conflict, and illegal trafficking, there are only approximately...
