Social Impact Statement Global change endangers the terrestrial vegetation that sustains us. Therefore, policymakers need to make informed decisions about what and where protect. However, with limited resources, we must decide whether protect intrinsic value of plants or their humans. Protecting both is possible. By investigating distributions over 3000 Canada's useful native defined in ethnobotanical databases, identified areas are essential harbouring plant benefits. Here, bridge biodiversity benefits it provides inform conservation policies by prioritizing species. Summary Plants foundational for ecosystems provide services humans, but little known distribution protection plants. address how well all captures diversity status human uses. We calculated metrics Canada at 1‐km 2 spatial scale based on species models a large plant‐use database use categories food feed, medicinal, biochemical genetic resources materials. used Species Protection Index (SPI) determine adequately represented protected derive new index—Useful Globally Endangered (USaGE)—to identify important combination usefulness (USa) extinction risk (GE) obtained from Committee Status Wildlife (COSEWIC) assessments. Overall, c. 30% has documented uses, richness correlated richness. Useful generally concentrated southern agricultural areas, exception some (e.g., medicinal also prevalent coastal boreal regions).

Oomycete communities are influenced by land use and disease status in Christmas tree production in Southern Québec, Canada

Environmental DNA, Journal Year: 2024, Volume and Issue: 6(2)

Published: March 1, 2024

Abstract Forests are threatened by many natural stressors intensified climate change and anthropogenic activities, which tend to increase their susceptibility pests pathogens. Consequently, oomycete‐related forest decline or dieback cases increasing in natural, urban, agricultural landscapes. It is this context that Christmas tree growers from Southern Québec, Canada, experiencing root rot problems, with reported incidences up 25%. In a previous study, seven Phytophthora spp. were associated problem, but the overall diversity of oomycetes has not yet been investigated. Hence, we use metabarcoding approach provide an overview diversity, richness, composition oomycete community fir plantations compared surrounding forests. We showed P. cryptogea cluster, europaea sansomeana , chlamydospora cluster significantly more abundant soils collected under diseased trees confirmed (including abietivora ) was most frequently showing rot‐like symptoms. Finally, report land (anthropogenic activities) shapes while can act as gateway for invading fact, results presented here suggested might already have crossed boundary other species follow, advocating importance improved surveillance various environments.

Sustainable Development versus Extractivist Deforestation in Tropical, Subtropical, and Boreal Forest Ecosystems: Repercussions and Controversies about the Mother Tree and the Mycorrhizal Network Hypothesis

Plants, Journal Year: 2024, Volume and Issue: 13(9), P. 1231 - 1231

Published: April 29, 2024

This research reviews the phenomenon of extractive deforestation as a possible trigger for cascade reactions that could affect part forest ecosystem and its biodiversity (surface, aerial, underground) in tropical, subtropical, boreal forests. The controversy disparities criteria generated international scientific community around hypothesis link between “mother trees” mycorrhizal networks coopetition nutrients, nitrogen, carbon are analyzed. objective is to promote awareness generate more knowledge about eventual impacts extraction. Public policies emphasized crucial mediators balanced sustainable development. Currently, effects on ecosystems poorly understood, which requires caution protection.

Native vs. Non-Native Plants: Public Preferences, Ecosystem Services, and Conservation Strategies for Climate-Resilient Urban Green Spaces

Land, Journal Year: 2025, Volume and Issue: 14(5), P. 954 - 954

Published: April 28, 2025

Climate change is reshaping urban environments, intensifying the need for resilient green space design and management that supports biodiversity, improves ecosystem services, adapts to changing conditions. Understanding trade-offs between native non-native species selection important developing climate-resilient spaces. This review examines public preferences versus plant their implications management. We critically analyse services biodiversity benefits provided by both plants in spaces, highlighting complex involved. Our findings indicate while can be underrepresented landscapes, they offer significant ecological including support local wildlife pollinators. Some studies have highlighted climate resilience of plants; however, are likely more affected change. Therefore, conservation strategies needed, especially endemic threatened species.

Climate change effects on the potential distribution of the endemic Commiphora species (Burseraceae) on the island of Socotra

Frontiers in Forests and Global Change, Journal Year: 2023, Volume and Issue: 6

Published: June 2, 2023

The Socotra Archipelago (Yemen) is an interesting biodiversity hotspot, with a significant proportion of endemic species that have evolved to survive in arid subtropical environment, inscribed as World Heritage Site by UNESCO. terrestrial ecosystems face several threats, including climate change, overgrazing and soil degradation. Island has four the genus Commiphora (Burseraceae). Little known about their local distribution ecology, yet these trees could be useful indicator species. Our study focuses on niche characterisation how change may affect them. aim improve insights into habitats provide essential basis for future management plans ecological restoration. We compared current forecasted potential under CMIP6 (Coupled Model Intercomparison Project) scenario, allowing us define target conservation areas assess extinction risks. To achieve this, we collected data field throughout Island, covering ranges species, applied three models (GAM, MaxEnt, RandomForest) using bioclimatic, topographic variables. Forecasts scenario were made bioclimatic variables from CMCC-CESM2 model two different socioeconomic pathways. Socotran mainly correlated clay content winter precipitation, while C. socotrana affected seasonal precipitation temperature.

Global change explains reduced seeding in a widespread New Zealand tree: indigenous Tūhoe knowledge informs mechanistic analysis

Frontiers in Forests and Global Change, Journal Year: 2023, Volume and Issue: 6

Published: June 27, 2023

Introduction Climate change is expected to exacerbate the pressures faced by already fragile ecosystems. Negative impacts on localized and culturally significant plant animal species within these ecosystems will have cascading effects for indigenous communities that interact with those species. Understanding how climate affects important seed crops may be particularly important, as seeds are critical forest regeneration well providing sustenance wildlife people. In central North Island/Te Ika-a-Māui of Aotearoa-New Zealand, Tūhoe elders Tuawhenua region observed declines in production large-fruited locally dominant tree Beilschmiedia tawa (tawa, Lauraceae) over last half century, which could related change. Methods We used trap data from six sites throughout geographic range measure trends crop size 1986 2020 determine weather factors affect crops. then predictors hindcast seeding changed forests 1910–2019, based historic data. Results Seed showed a decline through time across tawa’s range, was lower at more northerly sites. were synchronous among trees sites, but strongly asynchronous High associated cooler summer winter temperatures, high rainfall. region, increases temperatures appear contributed elders, model predicting years heavy fruiting become less frequent after 1940. Discussion Our study provides strong evidence undergoing changing seedfall patterns response climate. The biggest drivers we identified temperature, both negatively size.
