Les equacions de Navier-Stokes: Impredictibilitat fins i tot sense papallones?
Matemàticament, el moviment d’un fluid es descriu mitjançant les anomenades equacions de Navier-Stokes. En l’esperit de la mecànica newtoniana, aquestes equacions haurien de determinar el moviment futur del fluid a partir del seu estat inicial. Tanmateix,

Colombia and other tropical regions face a very high threat from torrential floods, which have resulted in over 25,000 deaths in a single event. Unfortunately, there is no comprehensive assessment methodology to zone and determine the magnitude of these disasters; therefore, this research aims to help fill this gap.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Abstract The intensification of extreme heat events in the Mediterranean basin poses growing threats to public health, particularly in climate‐vulnerable regions like the Valencian Region (eastern Spain). Despite the implementation of provincial and municipal heat prevention plans, their efficacy remains unevaluated, and most studies have focused on ...

Climatic niche position predicts population dynamics in Mediterranean shrubs after drought
Climatic conditions closer to the species' climatic niche centroid generally resulted in higher population growth in two Mediterranean shrubs, but demographic responses differed between species and were further influenced by drought‐induced vegetation die‐off.

Abstract Efficient weed management in commercial forestry requires reliable methods for distinguishing crop seedlings from competing vegetation during early plantation establishment. This study aimed to identify spectral wavelength ranges suitable for discriminating weeds from Eucalyptus saligna in young forest plantations.
