Protected areas provide major benefits for humans in the form of ecosystem services, but landscape degradation by human activity at their edges may compromise ecological functioning. Using multiple lines evidence from 40 years research Serengeti-Mara ecosystem, we find that such edge has effectively "squeezed" wildlife into core protected area and altered ecosystem's dynamics even within this 40,000-square-kilometer ecosystem. This spatial cascade reduced resilience was mediated movement...
Fire is a fundamental process in savannas and widely used for management. Pyrodiversity, variation local fire characteristics, has been proposed as driver of biodiversity although empirical evidence equivocal. Using new measure pyrodiversity (Hempson et al.), we undertook the first continent-wide assessment how affects protected areas across African savannas. The influence on bird mammal species richness varied with rainfall: strongest support positive effect occurred wet (> 650 mm/year),...
Fire is a key driver in savannah systems and widely used as land management tool. Intensifying human uses are leading to rapid changes the fire regimes, with consequences for ecosystem functioning composition. We undertake novel analysis describing spatial patterns regime of Serengeti-Mara ecosystem, document multidecadal temporal investigate factors underlying these patterns. MODIS active burned area products from 2001 2014 identify individual fires; summarizing four characteristics each...
Pyrodiversity, which describes fire variability over space and time, is believed to increase habitat heterogeneity thereby promote biodiversity. However, date there no standardised metric for quantifying pyrodiversity, so broad geographic patterns drivers of pyrodiversity remain unexplored. We present the first generalizable method quantify use it address fundamental questions what drives attributes constrain under different conditions, whether spatial grain‐dependent. linked MODIS burned...
Abstract The Critically Endangered hirola Beatragus hunteri exists in two populations, a natural population on the Kenyan–Somali border and translocated Tsavo East National Park, Kenya. is becoming increasingly important for survival of yet its status unknown little understood about factors that limit growth. Here we report size, distribution demographic parameters consider whether insufficient suitable habitat could be limiting has not increased since 2000, when last census was carried out,...
