Review of the use of deep learning algorithms in wildfire detection at an early stage in forest and wildland areas. Aim of the technique is to reduce loss of human lives and forest resources.
With successful reproduction and recruitment fundamental to the continued persistence of fish populations under future climate conditions, understanding the physiological mechanisms – including taxonomic and population variation – wherein high temperatures lead to reduced reproductive performance is crucial to identify and remediate any reproductive impairment caused by warming aquatic habitats. Future endocrine studies have an important role to play to that end, as understanding the hormone mechanisms that underlie reproductive inhibition at high temperature, as well as extending our understanding of those mechanisms to consider the potential ability for fish to acclimate either through prior developmental thermal experience or via transgenerational and epigenetic mechanisms (e.g., Veilleux et al., 2018), will be crucial for predicting how wild fish populations will be affected by climate warming. The results presented here and elsewhere for other species (e.g., Alix et al., 2020; Servili et al., 2020) have a crucial role to play by serving as a foundation to guide future research into how extreme warm temperatures predicted under future climate scenarios will impact fish reproduction.

This Editorial highlights the relationship between climate change, fires, floods and infectious diseases.
Sperm production and function are vulnerable to heat, and heatwave conditions are forecast to increase as our climate warms, so we examined these effects on female reproduction and mating behaviour in the flour beetle, Tribolium castaneum, a promiscuous ectotherm model in which fertility is damaged by environmental warming. We tested whether polyandrous matings, or polyandrous sperm stores, protect females against reduced male fertility caused by heatwave conditions, and whether females flexibly adjust their remating behaviour to enable fertility rescue. We found that polyandry protected females against reduced male fertility: monogamous matings with males exposed to heatwave conditions halved female offspring production, but opportunities to mate with five of these males allowed normal female reproductive output.

Climate change has accelerated the melting of Himalayan glaciers, with profound impacts on the planetary health realms of the Himalayan region. The complexity has been captured and mapped to explain linkages between melting glaciers and associated planetary health issues to help planning for better planetary health in nine subsystem categories: ecological services, disaster, water security, food security, energy security, livelihood and culture, migration, conflict and public health. In addition to the main SDGs, this article is indirectly related to SDG 1 (No Poverty) and SDG 10 (Reduced Inequalities).
This paper assesses the impact of geodiversity on biodiversity focusing on the relevance of patch- to hillslope-scale geodiversity for the slow-onset effects of climate change, including land and forest degradation, biodiversity loss and desertification. It also argues that geodiversity fits the concept of biodiversity hotspots, ecological niches and climatic refugee and that human-made geodiversity may either restore or degrade ecosystem functioning.
This paper looks into the negative effects of slow-onset events related to climate change in Southeast Asia ranging from economic, ecological, and social impacts. As such they require an integrated response option whether mitigation or adaptation that pays attention to the complexity of the intersection between human and natural systems.

This study looks into impacts caused by forest degradation and disturbance in the Amazon, which diminish carbon storage and erode ecological integrity, on the vitality of Indigenous Protected Areas (IPAs) and Protected Natural Areas (PNAs).
