García-Carmona, Minerva; Girona-García, Antonio; Oliveira, Bruna R.F.; Keizer, Jan Jacob; García-Orenes, Fuensanta; Mataix-Solera, JorgeLos musgos juegan un papel importante tras los incendios forestales actuando como colonizadores tempranos, estabilizando y protegiendo así el suelo frente a la erosión. Sin embargo, se desconoce el efecto de los musgos sobre la recuperación del suelo post-incendio. En este trabajo estudiamos los efectos a medio plazo del musgo sobre las propiedades físicoquímicas del suelo en una plantación de eucalipto de la r...
ScenaLand: a simple methodology for developing land use and management scenarios
Pastor, Amandine V; Nunes, João Pedro; Ciampalini, Rossano; Bahri, Haithem; Annabi, Mohamed; Chikhaoui, Mohamed; Crabit, Armand; Follain, StéphaneScenarios serve science by testing the sensitivity of a system and/or society to adapt to the future. In this study, we present a new land use scenario methodology called ScenaLand. This methodology aims to develop plausible and contrasting land use and management (LUM) scenarios, useful to explore how LUM (e.g. soil and water conservation techniques) may afect ecosystem services under global change in a wide r...
Biochemical and functional responses of stream invertebrate shredders to postwi...
Pradhan, Arunava; Carvalho, Francisco; Abrantes, Nélson; Campos, Isabel; Keizer, Jan Jacob; Cássio, Fernanda; Pascoal, CláudiaForests in Mediterranean Europe including Portugal are highly susceptible to wildfires. Freshwaters are often exposed to post-wildfire contamination that contains several toxic substances, which may impose risk to freshwater organisms and ecosystem functions. However, knowledge on the impacts of post-wildfire runoffs from different origins on freshwater biota is scarce. In forest streams, invertebrate shredders...
Impacts of climate change on reservoir water availability, quality and irrigati...
Rocha, João; Carvalho-Santos, Cláudia; Diogo, Paulo; Beça, Pedro; Keizer, Jan Jacob; Nunes, João PedroFuture climate for the Mediterranean climatic region is expected to bring an increase in temperatures, decrease in the precipitation quantity and shifts in the seasonal precipitation pattern. Although the impacts of climate change on water resources have been relatively well explored for the Mediterranean climatic region, the specific consequences for reservoirs and, in particular, water availability and irriga...
Water repellency reduces soil CO2 efflux upon rewetting
Sánchez-García, Carmen; Oliveira, Bruna R. F.; Keizer, Jan Jacob; Doerr, Stefan H.; Urbanek, EmiliaCarbon dioxide (CO2) efflux from soil represents one of the biggest ecosystem carbon (C) fluxes and high-magnitude pulses caused by rainfall make a substantial contribution to the overall C emissions. It is widely accepted that the drier the soil, the larger the CO2 pulses will be, but this notion has never been tested for water-repellent soils. Soil water repellency (SWR) is a common feature of many soils and ...

Wildfire impacts on freshwater detrital food webs depend on runoff load, exposu...
Carvalho, Francisco André Costa; Pradhan, Arunava; Abrantes, Nelson José Cabaços; Campos,Isabel; Keizer, Jan Jacob; Cássio, Fernanda; Pascoal, CláudiaIn the last decades, land-use changes have made Mediterranean forests highly susceptible to wildfires, which can cause several impacts not only on burnt areas, but also on adjacent aquatic ecosystems. Post-fire runoff from burnt areas may transport toxic substances to streams by surface runoff, including polycyclic aromatic hydrocarbons (PAHs) and metals, which can be noxious to aquatic organisms. Impacts on aq...
The influence of biochar particle size and concentration on bulk density and ma...
Verheijen, Frank G. A.; Zhuravel, Anna; Silva, Flávio C.; Amaro, António; Ben-Hur, Meni; Keizer, Jan JacobBiochar application to agricultural soils has been proposed as a way to increase crop production by improving soil chemical and physical properties. Liming potential and improved nutrient exchange on biochar surfaces are the most reported mechanisms. Wherever crops experience drought stress, improvements in soil water holding capacity (WHC) might also be an important mechanism. However, reported effects on soil...

Influência da utilização de uma cobertura orgânica no restabelecimento a médio-...
Puga, João Ricardo Lavoura; Oliveira, Maria João Saraiva de; Bastos, Ana Catarina; Gonçalves, Fernando; Keizer, Jan Jacob; Abrantes, Nelson José CabaçosAo longo das últimas décadas Portugal tem sido um dos países com maior incidência de fogos florestais na Europa. Um número crescente de estudos tem vindo a ser desenvolvido no sentido de encontrar estratégias de recuperação e gestão de áreas ardidas. A aplicação de coberturas orgânicas sobre a superfície do solo pós-incêndio é atualmente utilizada eficazmente como forma de proteger o solo da erosão. Porém, pouc...
