Abundance, trends, and challenges facing mountain goats throughout their North American distribution

open access: yesWildlife Society Bulletin, EarlyView.
Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...

Geographic distributions of rock glacier in Turkey: The case study of Erciyes rock glacier

open access: yes, 2021
Kaya buzulu, periglasiyel ve permafrost oluşum süreçlerinin en önemli göstergelerinden biridir. Genellikle kıtasal iklim bölgelerinde bulunur. Özellikle soğuk ve kurak iklimin hâkim olduğu dağların yüksek kesimlerinde görülür. Kaya buzulları, donmuş kaya ve buzun karışımıyla talus üzerinde oluşur. Maalesef şimdiye kadar Türkiye'de bu konu hakkında

Soil drying induces widespread productivity loss but unequal climate vulnerability among ecotypes of a foundational Arctic sedge

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As temperatures increase in the Arctic, hydrological change may lead to local soil drying through altered snowpack, evapotranspiration and drainage due to permafrost thaw.

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

open access: yesJournal of Animal Ecology, EarlyView.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.
