Artificial Intelligence in Agriculture, Journal Year: 2024, Volume and Issue: 12, P. 109 - 126

Published: May 31, 2024

In this study, we extensively evaluated the viability of state-of-the-art YOLOv8 architecture for object detection tasks, specifically tailored smoke and wildfire identification with a focus on agricultural environmental safety. All available versions were initially fine-tuned domain-specific dataset that included variety scenarios, crucial comprehensive monitoring. The 'large' version (YOLOv8l) was selected further hyperparameter tuning based its performance metrics. This model underwent detailed optimization using One Factor At Time (OFAT) methodology, concentrating key parameters such as learning rate, batch size, weight decay, epochs, optimizer. Insights from OFAT study used to define search spaces subsequent Random Search (RS). final derived RS demonstrated significant improvements over initial model, increasing overall precision by 1.39 %, recall 1.48 F1-score 1.44 [email protected] 0.70 protected]:0.95 5.09 %. We validated enhanced model's efficacy diverse set real-world images, reflecting various settings, confirm robustness in detecting fire. These results underscore reliability effectiveness scenarios critical safety work, representing advancement field fire through machine learning, lays strong foundation future research solutions aimed at safeguarding areas natural environments.

The Hell of Wildfires: The Impact on Wildlife and Its Conservation and the Role of the Veterinarian

Conservation, Journal Year: 2023, Volume and Issue: 3(1), P. 96 - 108

Published: Feb. 1, 2023

Wildfires are common occurrences worldwide that can destroy vast forest areas and kill numerous animals in a few hours. Climate change, rising global temperatures, precipitation, the introduction of exotic species plants (e.g., eucalyptus), intensive agriculture, deforestation have increased number fires their intensity destructive power. Nearly 4% land surface (30–46 million/km2) is burned annually. There many studies regarding impact wildfires on ecosystems, flora, domestic animals, humans. Even though recurrent problem around world, most time, they neglected issue, especially wildlife. The information available scarce dispersed across several bibliographical references, veterinarian teams, need to be trained act these situations. In this brief review, we describe different species’ behavior during wildfire, effects ecosystem, socioeconomic region. From veterinarian’s perspective, list major injuries expected observed how proceed. conclusion, discuss better prevention response measures wildfire scenario.

According to the definition provided by United Nations, “climate change” describes persistent alterations in temperatures and weather trends. These may arise naturally, such as fluctuations solar cycle. Nonetheless, since 19th century, human activities have emerged primary agent for climate change, primarily attributed combustion of fossil fuels coal, oil, gas. Climate change can potentially influence well-being, agricultural production, housing, safety, employment opportunities all individuals. The immune system is an important interface through which global affects health. Extreme heat, events environmental pollutants could impair both innate adaptive responses, promoting inflammation genomic instability, increasing risk autoimmune chronic inflammatory diseases.

Effects of grassland controlled burning on symbiotic skin microbes in Neotropical amphibians

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 10, 2024

Abstract Climate change has led to an alarming increase in the frequency and severity of wildfires worldwide. While it is known that amphibians have physiological characteristics make them highly susceptible fire, specific impacts on their symbiotic skin bacterial communities (i.e., bacteriomes) infection by deadly chytrid fungus, Batrachochytrium dendrobatidis , remain poorly understood. Here, we address this research gap evaluating effects fire amphibian bacteriome subsequent risk chytridiomycosis. We sampled Neotropical species Scinax squalirostris Boana leptolineata control plots before after experimental burnings. Fire was linked with a marked beta dispersion, proxy for microbial dysbiosis, alongside trend increased pathogen loads. By shedding light bacteriomes, study contributes our broader understanding vulnerable vertebrate species.

Trade-offs between sociality and gastrointestinal parasite infection in the context of a natural disaster

Animal Behaviour, Journal Year: 2024, Volume and Issue: 211, P. 147 - 161

Published: April 1, 2024

Parasites and infectious diseases constitute important challenges particularly for group-living animals. Social contact shared space can both increase parasite transmission risk, while individual differences in social capital help prevent infections. For example, high status individuals those with more or stronger affiliative partnerships may have better immunity and, thus, lower parasitic burden. To test health trade-offs the costs benefits of sociality, we quantified how load varied an individual's status, as well their relationships weakly strongly bonded partners, a free-ranging population rhesus macaques, Macaca mulatta. We found that was associated risk protozoa infection at older ages compared to younger low-status resources also be protective against under environmentally challenging situations, such natural disasters. Using cross-sectional data, additionally examined impact major hurricane on sociality - relationship this system influenced prevalence specific parasites independent sociality. Overall, our study adds growing evidence strong predictor highlights extreme environmental events could shape vulnerability resistance infection.

Published: Feb. 1, 2025

ABSTRACT Wildfire activity is increasing globally, highlighting the need to understand how fire disturbance affects species interactions. In particular, few studies have examined influences interactions among parasites, hosts and predators in freshwater streams. We characterised host–parasite parasite–predator involving nematode parasites (Family Mermithidae), mayfly (Order Ephemeroptera) trout ( Salvelinus fontinalis , Salmo trutta Oncorhynchus clarkii ) at 8 burned unburned stream sites southern Rocky Mountains for 2 years following severe wildfires. Mayfly density, infection probability, density of infected mayflies (infected mayflies/m were all lower 1 year after but returned levels similar years. Density increased with overall density; however, prevalence (%) ranged from 0% 26% across streams, there was no relationship between prevalence. Based on dissections > 20,000 mayflies, intermediate‐size (4–6 mm) family Baetidae had highest probability also most common size class found stomachs. did not affect number mermithids consumed per trout, prevalences by significantly than benthos, suggesting predator‐avoidance behaviour mayflies. Overall, our results suggest that mermithid responses reflected changes host consistent single‐host life cycle mermithids. These help integrate host–parasite–predator into understanding ecology implications parasite roles energy flow through food webs.

Abstract Background Humans have altered fire regimes across ecosystems due to climate change, land use and increasing ignition. Unprecedented shifts in affect animals contribute habitat displacement, reduced movement, increased mortality risk. Mitigating these effects require the identification of habitats that are susceptible wildfires. We designed an analytical framework incorporates risk mapping with species distribution modeling identify key Ursus arctos high probability Iran. applied random forest algorithm for mapping. also modeled brown bear predicted connectivity between them using models analysis, respectively. Finally, map, critical habitats, corridors were overlaid spatially at fire. Results identified 17 5245 km 2 connecting them, 40.06% 11.34% which covered by conservation areas, Our analysis showed 35.65% 23.56% Conclusions Since bears this semi-arid landscape rely on forests higher altitudes, it is likely shifting changing modifications reduce extent future. While not well known how affects bears, identifying its where wildfires occur first step manage potential impacts from species.
