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 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.

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 likely to...

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Keystone Species

Keystone Species

Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a pivotal role in the...

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.

Summary

A new framework prioritizes marine turtle conservation by assessing Regional Management Units (RMUs). It identifies the 11 most endangered RMUs, guiding global conservation efforts and highlighting data gaps for these widespread species.

Area of Science:

Marine Biology
Conservation Science
Ecology

Background:

Limited conservation resources necessitate robust frameworks for prioritizing actions, especially for widespread species with diverse threats.
Marine turtles are globally distributed with distinct populations (Regional Management Units - RMUs) facing varied threats and population trends.
Existing extinction risk assessments do not adequately address the distinct status of individual marine turtle RMUs.

Purpose of the Study:

To develop and implement a novel assessment framework for evaluating and prioritizing marine turtle Regional Management Units (RMUs) globally.
To create a "conservation priorities portfolio" system categorizing RMUs by paired risk and threat scores.
To identify patterns in risk, threats, and data gaps across different scales (global, species, ocean basin, geopolitical).

Main Methods:

Developed a new assessment framework to evaluate, compare, and organize 58 marine turtle RMUs based on status and threats.
Created a "conservation priorities portfolio" system using paired risk and threat scores.
Performed global, species-specific, ocean basin, and geopolitical assessments and rankings.

Main Results:

Characterized the risk and threats for all 58 marine turtle RMUs.
Identified the world's 11 most endangered marine turtle RMUs based on highest risk and threat scores.
Highlighted significant data gaps crucial for accurate conservation assessments.

Conclusions:

The developed framework provides guidance for research and conservation priorities at multiple scales for marine turtles.
This system serves as a model for conservation status assessments and priority-setting for other widespread, long-lived taxa.
Effective conservation requires addressing distinct population statuses and varying threat impacts across RMUs.
