Abstract:  Fire management is increasingly focusing on introducing heterogeneity in burning patterns under the assumption that “pyrodiversity begets biodiversity.” This concept has been formalized as patch mosaic burning (PMB), in which fire is manipulated to create a mosaic of patches representative of a range of fire histories to generate heterogeneity across space and time. Although PMB is an intuitively appealing concept, it has received little critical analysis. Thus we examined ecosystems… 
Local and global pyrogeographic evidence that indigenous fire management creates pyrodiversity
TLDR
The fieldwork and modeling results imply that the occurrence of long-unburnt habitat in fire-prone ecosystems may be an emergent property of patch scaling under fire regimes dominated by smaller fires, providing a model for understanding how anthropogenic burning alters spatial and temporal aspects of habitat heterogeneity.
No Net Loss of Species Diversity After Prescribed Fires in the Brazilian Savanna
Although savannas are fire-adapted ecosystems, prescribing fire for biodiversity conservation remains controversial at least in some regions where savannas occur. Faced with uncertainty, many
Testing the assumptions of the pyrodiversity begets biodiversity hypothesis for termites in semi-arid Australia
TLDR
This work suggests that encouraging a diversity of fire-ages for enhancing termite species richness in this study region is not necessary, and four key assumptions of the pyrodiversity begets biodiversity hypothesis are tested.
Managing fire mosaics for small mammal conservation: a landscape perspective
Summary 1. Fire is a major driver of ecosystem structure and function worldwide. It is also widely used as a management tool to achieve conservation goals. A common objective is the maintenance of
Beds are burning : small mammal responses to fire in tropical savannas of Northern Australia
The management of fire to conserve biodiversity and maintain ecosystem integrity is an ongoing challenge throughout the world. The response of plants and animals to fire is complex due to
Challenging the concept of Aboriginal mosaic fire practices in the Lake Eyre Basin
Mosaic burning is the deliberate creation of a mosaic of patches representing different fire histories. It is often recommended for management of Australia’s natural landscapes, on the assumption
The fire patchiness paradigm: a case study in northwest Queensland
Research into fire ecology has culminated in ‘the patchiness paradigm’. This is the view that numerous small fires, with variety in fire timing, frequency and intensity, will lead to habitat

TLDR
Maintaining over the long term a coarse-grained mosaic of large areas of midsuccessional vegetation in mallee ecosystems will need to be balanced against the short-term negative effects of large fires on many reptile species and a documented preference by species from other taxonomic groups, particularly birds, for older vegetation.
Effects of a large wildfire on vegetation structure in a variable fire mosaic.
TLDR
Test to what extent a large wildfire interacted with previous fire history to affect the structure of forest, woodland, and heath vegetation in Booderee National Park in southeastern Australia found that the strength and persistence of fire effects differed substantially between vegetation types, showing that even after a large, severe wildfire, underlying fire histories can contribute substantially to variation in vegetation structure.
