Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Area of Science:

Ecology
Conservation Biology
Fire Ecology

Background:

Mediterranean ecosystems are prone to large-scale wildfires (megafires).
Traditional views suggest post-fire recovery relies on recolonization (exogenous regeneration).
Emerging evidence indicates in situ survival of animals within burned areas.

Purpose of the Study:

To assess the impact of 2012 megafires on biodiversity in the eastern Iberian Peninsula.
To investigate the mechanisms of post-fire ecological recovery, including in situ survival.
To create a comprehensive database (POSTDIV) of recovery data for arthropods, reptiles, and plants.

Main Methods:

Established 12 plots per fire, sampling burned and unburned vegetation at varying distances from fire perimeters in 2013.
Monitored the recovery of arthropods, reptiles (and their parasites), and plants over 2–5 years post-fire.
Compiled data into the POSTDIV database, recording taxon abundance and cover-abundance.

Main Results:

The POSTDIV database contains 19,906 records across 457 arthropod taxa, 12 reptile taxa, 4 reptile parasite taxa, and 518 plant taxa.
Data covers 113,681 arthropod individuals, 503 reptile individuals, and 234 parasite individuals.
The database facilitates analysis of post-fire recovery dynamics and biodiversity resilience.

Conclusions:

Large-scale fires significantly affect Mediterranean ecosystem biodiversity.
The POSTDIV database provides valuable data for understanding ecological resilience and recovery processes.
Further research using POSTDIV can elucidate the roles of exogenous regeneration and in situ survival in post-fire ecosystems.
