We often take for granted today was once severely threatened and continues to demand strong protection. An example of this situation was the countless species of whales commercially exploited during…
The polar environments possess extreme light conditions, with midnight sun periods and polar nights[1]. Zooplankton[2] species have adapted different strategies to survive the polar night, reducing their activity in comparison…
Narwhals are cetaceans that inhabit the Arctic Ocean with a very curious particularity: a long tusk that has been the inspiration for many fantastic stories. For example, the existence of…
Marine resources are among the most important resources for humanity, whose demand will continue to increase as population increases. Consequently, effective and sustainable management is essential, as is learning from…
Climate change is affecting almost all regions and ecosystems. Particularly in the Arctic, where rapid sea-ice loss and increasing temperatures are altering the distribution and abundance of low trophic-level organisms,…
Penguins, one of the most abundant groups of seabirds in the Southern Ocean, feed mainly on cephalopods (e.g., squids and octopus). A recent study, led by our Hugo Guímaro, studied…
When we speak about pollution in the Poles, geographically isolated locations, we normally talk about atmospheric or aquatic transportation, or natural sources such as volcanoes. However, there are other ways…
The presence of plastics in polar regions has been recognised by several international research teams. Besides its presence in sediments, seawater and sea ice in the Artic and Antarctica, the…
Although Antarctica is the most remote region on Earth, it is intimately coupled to the rest of the climate system. Thus, the future of Antarctica is tied to that of…
Climate change is a major problem influencing several atmospheric and oceanic climate processes leading to climate warming, already affecting the abundance and distribution of wildlife around the world. The Antarctic…
