Greater diversity of Iberian spiders previously unknown
Greater diversity of Iberian spiders previously unknown
Populations of peninsular spiders that make aerial spider webs and move around the air by ballooning (using the silk threads as parachutes) present a more homogeneous genetics structure and are better connected between them. However, species of nocturnal spiders, which hunt on the ground and have a low dispersal capacity, show less genetically connected populations and are more vulnerable to local extinction processes due to environmental factors.

Space and time: how to better understand biological processes in plants
Space and time: how to better understand biological processes in plants
If the perspective of space and time is not properly applied to plant research, the understanding of biological processes is limited as well as the response to the threats that endanger the life of plants worldwide. This is one of the main conclusions of an article published in the journal Trends in Plant Science by Professor Sergi Munné-Bosch, from the Faculty of Biology , the Biodiversity Research Institute ( IRBio ) and the Institute for Nutrition and Food Safety ( INSA ) of the UB.

Complex behaviour of sea urchins regarding the predators' threat
Complex behaviour of sea urchins regarding the predators’ threat
Sea urchins, albeit having a limited and ancestral sensory system, can show a complex behaviour when escaping a predator. These marine invertebrates tend to move slowly and with unpredictable movements, but when they smell a predator, they escape following a ballistic motion -straightforward, quick and directional- to escape the threat.

Savannah chimpanzees, a model for the understanding of human evolution
Savannah chimpanzees, a model for the understanding of human evolution
To prosper, most great apes need lush forests in Africa (bonobos, chimpanzees, and gorillas) or Southeast Asia (orangutans), except for some groups of chimpanzees that live in savannahs, habitats characterised by high temperatures and very low seasonal rainfall. Adriana Hernández, Serra Hunter professor at the Faculty of Psychology of the University of Barcelona, co-led the study conducted by an international team of primatologists who reviewed the existing research on the behaviour and ecology of savannah chimpanzees to understand how these apes adapt to extreme conditions.

The colonization of the Azores began seven hundred years before the arrival of the Portuguese
The colonization of the Azores began seven hundred years before the arrival of the Portuguese
The first settlers in the Azores Islands arrived seven hundred years ago before the first Portuguese arrived there in the 15th century as stated in the official historiography. This is one of the main conclusions of a study carried out by an international and multidisciplinary team in which the experts Alberto Sáez and Olga Margalef, from the Department of Earth and Ocean Dynamics of the Faculty of Earth Sciences of the UB, -have taken part.

Extreme volcanism did not cause the massive extinction of species in the late Cretaceous
Extreme volcanism did not cause the massive extinction of species in the late Cretaceous
A study published in the journal Geology rules out that extreme volcanic episodes or peaks in the eccentricity of the Earth's orbit around the sun had any influence on the massive extinction of species in the late Cretaceous. The results confirm the hypothesis that it was a giant meteorite impact what caused the great biological crisis that ended up with the dinosaur lineages and other marine and terrestrial organisms 66 million years ago.

The ocean plastic sink that went away with the rivers
The ocean plastic sink that went away with the rivers
The amount of plastic discharged by rivers to our oceans and seas has been overestimated by two to three orders of magnitude. This would explain why a large volume of microplastics seems to disappear in a mysterious ocean sink.

The UB takes part in a study that reveals the recent tendency in the evolution of snow in western Pyrenees
A study published in the International Journal of Climatology , in which several researchers of the UB participated, analysed for the first time the recent evolution of snow at high levels in the Catalan Pyrenees. The study shows that over the last twenty years, at more than 2,000 meters high, the snow has not decreased but there has been an increase of snow-shape rain during the winter.

Intensity of phytoplankton production during Antarctic summer affects the structure of seafloor ecosystems
Understanding the evolution of the polar sea ice is not enough to study the effects of the climate change on marine ecosystems in Antarctic seafloors. It is also necessary to determine the intensity of phytoplankton local production during the Antarctic summer, as stated in a new study by a research team of the Faculty of Biology and the Biodiversity Research Institute ( IRBio ) of the UB, published in the journal Marine Environmental Research .

Climate change ravages coralligenous architects in the Mediterranean
Climate change ravages coralligenous architects in the Mediterranean
Recerca Marine heatwaves are dramatically affecting the marine ecosystems of the world and the Mediterranean is no exception. In the Mediterranean, these extreme climate episodes and its resulting massive mortality of species are getting more and more intense and frequent. To date, most of the studies analysed the effects of these perturbations on specific species and populations, although researchers still do not know how this affects the functioning of the involved ecosystems.
