Abstract In the province of British Columbia, Canada, four most severe wildfire seasons last century occurred in past 7 years: 2017, 2018, 2021, and 2023. To investigate trends activity fire-conducive climate, we conducted an analysis mapped perimeters annual climate data for period 1919–2021. Results show that after a century-long decline, fire increased from 2005 onwards, coinciding with sharp reversal wetting trend 20th century. Even as precipitation levels remain high, moisture deficits have due to rapid warming evaporative demand. Bottom-up factors further influence activity, legacy wildfires, insect outbreaks, land-use practices continually regimes. The compound effects climate-induced changes altered fuels now force Columbians confront harsh reality more frequent years intense prolonged activity.

Climate change and the sustainable use of medicinal plants: a call for “new” research strategies

Climate change and human activities severely impact the viability of plants ecosystems, threatening environment, biodiversity, sustainable development plant-based products. Biotic abiotic (ecosystem) determinants affect species distribution long-term survival, which in turn influence quality used as herbal medicines other high-value In recent decades, diverse anthropogenic impacts have significantly affected these aspects. change, excessive plant exploitation, habitat loss, vulnerability, factors adversely growth, reproduction, adaptation populations, well volume primary materials supplied to pharmaceutical markets. Despite growing challenges, there is limited knowledge potential strategies prevent or mitigate impacts, particularly for vulnerable collected from wild harvested traditional production systems. Hence, effective preserving increasing populations are urgently needed. this study, we propose a new framework including main sustainability better understand address vulnerability species, hence climate change. We assess applicability our proposed via seven case studies (i.e., Aquilaria malaccensis Lam., Boswellia sacra Flück., Crocus sativus L., Panax quinquefolius Pilocarpus microphyllus Stapf ex Wardlew., Rhodiola rosea Warburgia salutaris (G.Bertol.)

Their economic importance, combined with rising demands specific risks overexploitation, also key considered here.

Protected area designation and management in a world of climate change: A review of recommendations

Abstract Climate change is challenging conservation strategies for protected areas. To summarise current guidance, we systematically compiled recommendations from reviews of scientific literature (74 fitting inclusion criteria) about how to adapt in the face climate change. We focussed on designation and management areas terrestrial landscapes, boreal temperate regions. Most belonged one five dominating categories: (i) Ensure sufficient connectivity; (ii) Protect refugia; (iii) a few large rather than many small areas; (iv) predicted become important biodiversity future; (v) Complement permanently with temporary protection.

Acclimation capacity to global warming of amphibians and freshwater fishes: Drivers, patterns, and data limitations

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(5)

Abstract Amphibians and fishes play a central role in shaping the structure function of freshwater environments. These organisms have limited capacity to disperse across different habitats thermal buffer offered by systems is small. Understanding determinants patterns their physiological sensitivity life history is, therefore, imperative predicting impacts climate change systems. Based on systematic literature review including 345 experiments with 998 estimates 96 amphibian (Anura/Caudata) 93 fish species (Teleostei), we conducted quantitative synthesis explore phylogenetic, ontogenetic, biogeographic (thermal adaptation) upper tolerance (CT max ) acclimation (acclimation response ratio, ARR) as well influence methodology used assess these traits using conditional inference tree analysis. We found globally consistent CT ARR, phylogeny (taxa/order), experimental methodology, climatic origin, stage significant traits. The analysis demonstrated that does not primarily depend origin but temperature duration, stage. Higher temperatures longer times led higher values, whereby Anuran larvae revealed than older stages. ARR was more twice amphibians. Differences between stages were significant. In addition phylogenetic differences, also depended ramping rate, adaptation local variability. However, amount data early too small, methodologically inconsistent, phylogenetically unbalanced identify potential cycle bottlenecks We, propose methods improve robustness comparability /ARR stages, which crucial for conservation biodiversity under change.

Conserving biodiversity in the face of rapid climate change requires a shift in priorities

Wiley Interdisciplinary Reviews Climate Change, Journal Year: 2022, Volume and Issue: 14(1)

Abstract The field of conservation aims to protect biodiversity—the diversity life on earth in all its forms. Traditional objectives and measures have already been expanded modified response shifting social values climate‐related challenges. As climate change progresses, we argue that these changes will need be accelerated. First, an even greater fraction prioritize the basic well‐being humans, especially areas where humans are strongly dependent their natural surroundings. For example, urban biodiversity low‐impact forms agriculture forestry reconcile contributions should increasingly viewed as compatible with objectives. Second, more allow for, foster, biodiversity. Indeed, changing species' characteristics biotic community composition not only adaptive responses inevitable but will, many instances, also necessary maintain functioning ecosystems. Conversely, attempts a historical state likely become difficult, expensive, possibly counterproductive. Finally, addition continuing adaptation work, efforts focus reducing atmospheric carbon concentrations. We explore how collectively transforming they potential lead just sustainable world despite impending change.

Are climate change adaptation strategies working? A call to expedite learning

Abstract Evidence is lacking for what constitutes effective climate change adaptation to successfully conserve and steward ecosystems. Yet we urgently need this information develop robust strategies keep pace with unprecedented change, given our limited resources do so. This includes not just understanding if a strategy in single application, but perhaps more importantly has proven across sites where it been applied, or benefits only under certain sets of conditions. learning the field currently missing necessary bringing scale. We propose an approach that can guide efficacy testing varying levels baseline knowledge ecosystem complexity. The clearly defining conservation goals vulnerabilities, methodically collecting site metrics inform analysis efficacy, evaluating communicating both positive negative results order advance field. Using meta‐analyses post‐hoc quickly scale meaningful way. Furthermore, explicitly incorporating into processes support growth spark creative, adaptive management approaches will increase likelihood reducing vulnerability.

A good idea or just an idea: Which adaptation strategies for conservation are tested?

Biological Conservation, Journal Year: 2023, Volume and Issue: 286, P. 110276 - 110276

Several highly cited review articles identify recommended adaptation strategies for conservation. However, those reviews do not include evaluation of whether the measures were tested and found to be effective in reducing climate change vulnerability. The basic question this paper is determine if there has been assessment potential effectiveness recommendations conservation reported published literature, so, what kind was used. To answer question, literature surveyed from references previous papers focused on recommendations, augmented by a targeted search studies that assess actions listed reviews. Identified categorized study type according hierarchy efficacy testing. result very modest number experimentally (n = 13), including only one indicating chosen strategy did achieve its intended goal, through monitoring. For some efficacy-assessing identified. There appears significant shortage presenting evidence would most useful determining action likely confer desired improvement, as well stagnation growth field. This points need more efforts monitor evaluate biodiversity management. Without it, we cannot learn which are good ideas.
