Published: March 3, 2025

Abstract Frequent, large-scale wildfires threaten ecosystems and human livelihoods globally. To effectively quantify attribute the antecedent conditions for wildfires, a thorough understanding of Earth system dynamics is imperative. In response, we introduce SeasFire datacube, meticulously curated spatiotemporal dataset tailored global sub-seasonal to seasonal wildfire modeling via observation. The datacube consists 59 variables including climate, vegetation, oceanic indices, factors. It offers 8-day temporal resolution, 0.25° spatial covers period from 2001 2021. We showcase versatility exploring variability seasonality drivers, causal links between ocean-climate teleconnections predicting patterns across multiple timescales with Deep Learning model. have publicly released appeal scientists Machine practitioners use it an improved anticipation wildfires.

Widespread resilience of animal species, functional diversity, and predator–prey networks to an unprecedented gigafire

Journal of Applied Ecology, Journal Year: 2024, Volume and Issue: unknown

Abstract Climate change is altering fire regimes globally, leading to an increased incidence of large and severe wildfires, including gigafires (>100,000 ha), that homogenise landscapes. Despite this, our understanding how large, wildfires affect biodiversity at the landscape scale remains limited. We investigated impact a gigafire occurred during unprecedented 2019–20 Australian ‘Black Summer’ on terrestrial fauna. selected 24 study landscapes, each 0.785 km 2 in size, represented gradient extent high severity fire, unburnt vegetation, diversity classes (‘pyrodiversity’). used wildlife cameras survey across quantified species activity, community functional diversity, predator–prey network metrics.

The House Is Burning: Assessment of Habitat Loss Due to Wildfires in Central Mexico

Fire, Journal Year: 2024, Volume and Issue: 7(4), P. 134 - 134

Published: April 12, 2024

Fire suppression and climate change have increased the frequency severity of wildfires, but responses many organisms to wildfire are still largely unknown. In this study, we assessed risk habitat loss for amphibians, mammals, reptiles caused by wildfires in central Mexico. We accomplished by: (1) determining likelihood occurrence over a 12-year period using historical records Poisson probability mass function pinpoint most susceptible areas wildfire; (2) evaluating species exposure identifying natural land use that aligns with potential distribution biodiversity; (3) assessing vulnerability based on classifications established IUCN CONABIO. Our findings unveiled three regions exhibiting concentration high-risk values. Among these, two positioned near major urban centers, while third lies southeastern sector Nevado de Toluca protection area. Amphibians emerged as taxonomic group severely impacted, substantial number falling within Critically Endangered categories, closely followed mammals reptiles. Furthermore, identified correlation between location zones agricultural areas. This study revealed hotspots can offer valuable guidance strategic initiatives fire-prone associated Moreover, future studies should contemplate integrating field data enhance our comprehension actual effects spatial these animal groups.

Multi‐taxon biodiversity responses to the 2019–2020 Australian megafires

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(23), P. 6727 - 6740

Published: Oct. 12, 2023

Conditions conducive to fires are becoming increasingly common and widespread under climate change. Recent fire events across the globe have occurred over unprecedented scales, affecting a diverse array of species habitats. Understanding biodiversity responses such is critical for conservation. Quantifying post-fire recovery problematic taxa, from insects plants vertebrates, especially at large geographic scales. Novel datasets can address this challenge. We use presence-only citizen science data iNaturalist, collected before after 2019-2020 megafires in burnt unburnt regions eastern Australia, quantify effect diversity responses, up 18 months post-fire. The geographic, temporal, taxonomic sampling dataset was large, but effort discoverability were unevenly spread. used rarefaction prediction (iNEXT) with which we controlled completeness among treatments, estimate indices (Hill numbers: q = 0-2) nine broad taxon groupings seven habitats, including 3885 species. estimated an increase Australian burnt, compared regions.

Lost in the ashes? Broadscale passive monitoring provides limited insight into the impacts of Australia's megafires on biodiversity

Extreme environmental disturbances such as fires are predicted to increase in severity and extent with climate change. To better understand ecological impacts of unprecedented scales disturbance, empirical monitoring data urgently needed. Broadscale passive networks camera traps or acoustic recorders an increasingly popular approach for monitoring.

Context Fire has played an integral role in regulating patterns of biodiversity for millions years. However, anthropogenic disturbance and climate change altered fire activity – driving increases both severity scale. The effect now on the persistence is poorly known, especially frogs. Studies examining frog responses to usually have small sample sizes, focus upon geographic areas are based low-severity fires, which can mean results not applicable high-severity such as those expected under future change. Aims Our aims were examine (1) species, measured by species richness, up 18 months post-fire, (2) effects varying richness recovery, where we higher lead lower after fire. Methods Using large-scale citizen science data from Australian Museum’s FrogID project, coupled with remotely sensed data, present a spatially taxonomically broad analysis post-fire recovery 2019/2020 ‘Black Summer’ bushfires. Key We reveal no overall decrease frogs short- long-term post-fire. Furthermore, did decline increasing severity. Instead, its response was highly site-specific. Conclusions provide evidence that widespread common persisted most sites concluded this potentially due their ability shelter adequately and/or La Niña-driven high rainfall offering conditions conducive breeding persistence.

Identifying hotspots of particularly rich or localised biodiversity is key strategy for prioritising areas protection and management. However, different measures may lead to the prioritisation conservation.

Spatial patterns frog largely correlate with each other, previous studies in plants other vertebrates, endemism both concentrated montane uplands correlated paleoclimatic stability.
