Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

EVALUATING REMOTE SENSING TECHNIQUES FOR MONITORING GRASSLAND DEGRADATION

Caminhos de Geografia
Ecosystem degradation is one of the most significant environmental challenges worldwide. In particular, grassland degradation poses serious threat to agricultural productivity, species diversity, and soil stability. This study aimed to compare the applicability of two remote sensing techniques – the Linear Spectral Mixture Model (LSM) and the Grassland

Restoration prospects for Heitutan degraded grassland in the Sanjiangyuan [PDF]

Journal of Mountain Science, 2013
Abstract In many ecosystems ungulates have coexisted with grasslands over long periods of time. However, high densities of grazing animals may change the floristic and structural characteristics of vegetation, reduce biodiversity, and increase soil erosion, potentially triggering abrupt and rapid changes in ecosystem condition.

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Holistic management – a critical review of Allan Savory’s grazing method [PDF]

, 2016
Allan Savory is the man behind holistic grazing and the founder of the Savory Institute. Savory claims that holistic grazing can stop desertification and reduce atmo­spheric carbon dioxide levels to pre-industrial levels in a few decades. In this report,

Potential for soil organic carbon sequestration in grasslands in East African countries: A review [PDF]

, 2020
Grasslands occupy almost half of the world's land area. Soil organic carbon (SOC) is a key indicator of soil fertility and grassland productivity. Increasing SOC stocks (so‐called SOC sequestration) improves soil fertility and contributes to climate ...

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

Ecography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.
