Redirecting fire-prone Mediterranean ecosystems toward more resilient and less flammable communities

Journal of Environmental Management, 2018
The extensive abandonment of agricultural lands in the Mediterranean basin has led to large landscapes being dominated by early-successional species, characterized by high flammability and an increasing fire risk. This fact promotes fire occurrence and places ecosystems in a state of arrested succession.

Post‐burning germination responses of woody invaders in a fire‐prone ecosystem

Austral Ecology, 2019
AbstractIt has been frequently recognised that there is a positive feedback between plant invasion and fire underlying invasion success in fire‐prone ecosystems. Accordingly, the response of woody alien species germination to fire may have direct implications on their invasiveness in those ecosystems, particularly when fruit ripening occurs in the fire

Vegetation Management for Promoting Ecosystem Resilience in Fire‐Prone Mediterranean Shrublands

Restoration Ecology, 2009
Abstract Dense shrublands constitute highly hazardous fuels in Mediterranean countries. The combination of agricultural land abandonment and fire occurrence in many Mediterranean areas has led to a landscape dominated by shrublands where resprouter species are scarce or absent.

Climate change induced declines in fuel moisture may turn currently fire-free Pyrenean mountain forests into fire-prone ecosystems

Science of The Total Environment, 2021
Fuel moisture limits the availability of fuel to wildfires in many forest areas worldwide, but the effects of climate change on moisture constraints remain largely unknown. Here we addressed how climate affects fuel moisture in pine stands from Catalonia, NE Spain, and the potential effects of increasing climate aridity on burned area in the Pyrenees ...

Fire: plant functional types and patch mosaic burning in fire-prone ecosystems

Progress in Physical Geography: Earth and Environment, 2008
Shared fire-survival and fire-persistence traits are found in taxonomically unrelated plant species that commonly grow in fire-prone ecosystems. Such traits include resprouting, after fire has killed the above-ground biomass, and postfire seed release after the death of individual plants. Classification of such traits has led to a change in focus from

Ecology of plant resprouting: populations to community responses in fire-prone ecosystems

Plant Ecology, 2011
Resprouting has emerged as a key functional trait in plant ecology over the past decade with more than 400 papers published since 2000 (Web of Science). This special issue of Plant Ecology brings together a set of papers that advance our understanding of this functional trait, in the quest for developing a better conceptual framework for predicting ...

Ecophysiology of Seed Germination in Composites Inhabiting Fire-prone Mediterranean Ecosystems

1997
Within the framework of a research project concerning adaptive mechanisms of postfire regeneration in Mediterranean ecosystems, the ecophysiology of seed germination was studied in the following composites: Dittrichia viscosa (L.) Greuter, Helichrysum stoechas (L.) Moench ssp. barrelien (Ten.) Nyman and Phagnalon graecum Boiss. & Heldr.

Long-term management actions of fire-prone Mediterranean ecosystems under climate change using fuel reduction and post-fire restoration

2023
Forest fires and extreme droughts will continue to be main disturbances in Mediterranean ecosystems, given the ongoing and projected climatic changes. In fact, an exacerbation of some aspects of their regime is expected. In this perspective, it is fundamental to design adaptive management strategies that can reduce the impact of disturbances and ...

Scatter-hoarding rodents disperse seeds to safe sites in a fire-prone ecosystem

Plant Ecology, 2015
Fire can potentially decimate soil seed banks, even for species that are abundant in fire-prone areas. Many plants, like the widespread and dominant members of the genus Arctostaphylos in the fire-prone California Floristic Province, have seeds that (i) have no clear adaptions for dispersal and (ii) experience lethal fire temperatures if present on or ...
