NatureNeanderthal coasteering and the first Portuguese hominin tracksites - Scientific ReportsMultiple sources of evidence for the systematic use of coastal ecosystems and resources by Neanderthals are known. Fossil hominin footprints offer direct portraits of individual or social group presence and locomotor behavior, and interspecific interactions, in the coastal ecospace. Here we describe the first two hominin tracksites found in the southwestern most region of Europe. At Monte Clérigo, dated to 78 ± 5 ka, trackways of three individuals demonstrate how Neanderthals navigated dune landscapes. These behaviors suggest route planning, with dune systems serving as advantageous settings for ambush hunting or stalking prey. A single footprint at Praia do Telheiro site, dated to 82 ± 5 ka, sustains the presence of Neanderthals in the dune ecosystem during Marine Isotope Stage (MIS) 5a. Network analysis provided dietary preferences and ecological interactions of Neanderthals in coastal areas. A review of the Neanderthal coastal sites associated with faunal evidence shows that their diet was primarily centered on cervids, horses and hares. The consistent presence of these mammal taxa highlights their role as reliable food sources, irrespective of the varying environments inhabited by Neanderthals. In addition, the Neanderthal diet also incorporated animals from neighboring littoral habitats, indicating a broad foraging strategy that capitalized on local biodiversity.

Climate change drives record-breaking heat in Iceland and Greenland challenging cold adapted ecosystems and societies

On May 15, #Egilsstaðir Airport recorded 26.6°C, breaking the previous record for #Iceland’s highest May temperature, while regions of the country saw temperatures more than 10°C above average (Icelandic Met Office, 2025). The #Ittoqqortoormiit station in #Greenland saw temperatures reach 14.3°C on May 19, which is more than 13°C above the May average daily maximum temperature of 0.8°C (#DMI, 2025).

These high temperatures were caused by a steady flow of warm air from the south, caused by a high-pressure system near the #Faroe Islands and a low-pressure system south of #CapeFarewell. This #weather setup lasted for about nine days, bringing unusually warm weather to the area. While similar patterns have happened before, this #heatwave stood out because it came so early in the year and lasted for so long.

While few impacts have been reported, numerous studies demonstrate that unusually high temperatures early in the year can have significant impacts on local ecosystems. These #ecosystems, adapted to very cold climates, are sensitive to temperature shifts, and disruptions to their delicate balance can lead to consequences not only for the ecosystems themselves, but also for the communities that depend on them.

Temperate forest (Biomes 🌍)

A temperate forest is a forest found between the tropical and boreal regions, located in the temperate zone. It is the second largest terrestrial biome, covering 25% of the world's forest area, only behind the boreal forest, which covers about 33%. These forests cover both hemispheres at latitudes ranging from 25 to 50 degrees, wrapping the planet in a belt similar to t...
