Alongshore upwelling modulates the intensity of marine heatwaves in a temperate coastal sea.

Analyses of long-term temperature records based on satellite data have revealed an increase in the frequency and intensity of marine heatwaves (MHWs) in the world oceans, a trend directly associated with global change according to climate model simulations. However, these analyses often target open ocean pelagic systems and rarely include local scale, field temperature records that are more adequate to assess the impact of MHWs close to the land-sea interface. Here, we compared the incidence and characteristics of open ocean MHWs detected by satellites with those observed in the field over two decades (1998-2019) at two temperate intertidal locations in the central Cantabrian Sea, southern Bay of Biscay.

Demography_Lab, an educational application to evaluate population growth: Unstructured and matrix models.

Training in Population Ecology asks for scalable applications capable of embarking students on a trip from basic concepts to the projection of populations under the various effects of density dependence and stochasticity. Demography_Lab is an educational tool for teaching Population Ecology aspiring to cover such a wide range of objectives. The application uses stochastic models to evaluate the future of populations.

A regime shift in intertidal assemblages triggered by loss of algal canopies: A multidecadal survey.

Canopy-forming macroalgae recently experienced a worldwide decline. This is relevant, because canopies sustain complex food webs in temperate coasts. We assessed the die-back of the canopy-forming alga Fucus serratus in N Spain, at its warm distributional range boundary, and its effects on associated assemblages.

Spatio-temporal dynamics of Codium populations along the rocky shores of N and NW Spain.

The green alga Codium fragile ssp. fragile (hereafter C. fragile) has long been assumed to outcompete and displace its native congeners via cryptic invasion.

Pop-Inference: An educational application to evaluate statistical differences among populations.

Pop-Inference is an educational tool designed to help teaching of hypothesis testing using populations. The application allows for the statistical comparison of demographic parameters among populations. Input demographic data are projection matrices or raw demographic data.

Effects of the 'Prestige' oil spill on macroalgal assemblages: large-scale comparison.

An assessment of the effects of the 'Prestige' oil spill on intertidal, macroalgal assemblages was carried out comparing abundance data obtained before and after the spill. Four zones in the North and Northwest coast of Spain were sampled, one of them located at the immediate vicinity of the spill, the zone most heavily oiled. Macroalgal assemblages had similar structure between years.

A continental scale evaluation of the role of limpet grazing on rocky shores.

It is critical for our knowledge of biodiversity and ecosystem processes to understand how individual species contribute to ecosystem processes and how these contributions vary in space and time. We used a manipulative field experiment in five locations over 17 degrees of latitude [from southern Portugal to the Isle of Man (British Isles)] to determine the relative response of rocky intertidal algal assemblages released from control by the grazing of limpets. Response ratios showed that when limpets were removed there was a trend of effects from north to south.
