Assessing the impact of natural disturbances on plant biodiversity is crucial amid loss and climate change. Research highlights dynamic shifts driven by environmental factors, change, human activity, emphasizing need to maintain ecosystem stability for conservation sustainable development, particularly in arid semi-arid regions. This study, conducted between 2021 2023, focused dynamics communities argan tree reserve areas. Six orchards were selected as study sites detailed investigation. A total 82 species belonging 25 families identified, with 23 documented 21 including six endemic Morocco (Frankenialaevis subsp. velutina, Ononisnatrix arganietorum, Rumex papilio, Andryala integrifolia cedretorum, Chiliadenushesperius, Reseda difussa). The majority plants present area annual biennial herbaceous types, exhibiting minimal seasonal within communities. However, how respond effects fluctuating remains unclear. explores indirect community metrics orchards, assessing diversity, biomass, density across different orchard types. It influence climate, soil properties, biotic interactions dynamics. We utilized alpha diversity indices (Shannon, Simpson, Pielou’s, Margalef’s) beta (Jaccard Sorenson Similarity) examine these patterns. Seasonal changes predominantly influenced temperature precipitation, while diverse types shaped relief, water balance contributed ecological functions. key findings indicated highest “Tioughza” most significant “Imoulass” “Ezzaouite”. Soil nutrients (N, C, P) showed a positive correlation highlighting their vital role biomass accumulation, whereas temperature, C/N ratio, loam percentage found be richness. Mixed modeling revealed relation but no effect (Shannon Index) elevation. concludes that texture significantly shape relationships density, recommending further research into among cover, fertility support management orchards.

The Invasive Plant Amaranthus spinosus L. Exhibits a Stronger Resistance to Drought than the Native Plant A. tricolor L. under Co-Cultivation Conditions When Treated with Light Drought

Plants, Год журнала: 2024, Номер 13(16), С. 2251 - 2251

Опубликована: Авг. 13, 2024

Drought may facilitate the invasion process of invasive plants, mainly because plants can obtain a stronger growth competitiveness than native under drought. It is therefore imperative to illuminate mechanisms underlying successful drought, with particular focus on differences in resistance and This study aimed elucidate between plant

Invasive species are the major cause of native biodiversity loss and extinction, which have predominantly affected one world's 'hottest hotspots' located in Western Ghats, India with varied intensity. Therefore, present study, an investigation has been undertaken to model potential habitat dominant invasive plant (IPSs) viz., Chromolaena odorata (L.) R.M.King & H.Rob. Lantana camara L. current future climate change scenarios by evaluating influence bioclimatic topographical variables using distribution modelling (SDM). The study exhibited large invasion proliferation C.

Role of plant functional traits in the invasion success: analysis of nine species of Asteraceae

BMC Plant Biology, Год журнала: 2024, Номер 24(1)

Опубликована: Авг. 19, 2024

Various attributes are hypothesized to facilitate the dominance of an invasive species in non-native geographical and ecological regimes. To explore characteristic family Asteraceae, a comparative study was conducted among nine this family, co-occurring western Himalayan region. Based on their nativity invasion status, were categorized as "Invasive", "Naturalized", "Native". Fifteen plant functional traits, strongly linked with invasion, examined test species. The analyses revealed strong dissimilarity between all traits (except leaf carbon [Leaf C]) represented by "Invasive" "Native" categories most area [LA], nitrogen N], Leaf C, carbon-nitrogen ratio [C: N]) "Naturalized" categories. Similarly, also varied significantly for N, capitula per m² population [C

Projecting global shifts in the invasive potential of Bidens pilosa L. under climate change using species distribution models

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Май 15, 2025

Invasive species pose significant threats to ecosystems by reducing biodiversity, introducing new diseases, and competing with native for resources. Bidens pilosa L., a globally invasive weed originating in tropical America, severely impacts agricultural productivity infesting 31 economically vital crops across over 40 countries. This study examined the global distribution of under current future climate scenarios. Using models occurrence data, we identified key factors influencing its spread, including temperature, precipitation, human influence. Our findings suggest likely decline suitable habitats regions an expansion into temperate regions, suitability decreasing higher temperatures. Additionally, historical reconstructions emphasize that rapid spread was facilitated maritime trade routes. Management strategies are proposed need enhanced control measures high-risk areas conservation efforts range America. Overall, this research contributes understanding dynamics B. informs proactive management mitigate ecological economic impacts.

Plant Invasion and Climate Change: A Global Overview

Опубликована: Янв. 1, 2023

The phenomenon of plant invasion is a consequence invading plants' exceptional range expansion into new geographic areas. Even though older naturalists were aware the problem invasion, research on subject has intensified mainly in last two decades. attributes migrated alien plants, as well biotic and abiotic aspects introduced environment—which may be investigated with aid numerous hypotheses—are what lead to successful invasions. After going through an introduction-naturalization-invasion continuum, these species dominate invaded ecosystem, homogenize floristic composition, jeopardize rare unique species, disturb ecosystem stability, incur high social financial losses. In future, it anticipated that will increase significantly, part due global trade, agriculture, other human activities, somewhat anthropogenically induced climate change. Most invasive respond positively various consequences change, viz. rising temperatures, augmented nitrogen accumulation, enhanced CO2 levels, erratic precipitation regimes, etc. With growing fierceness recognized invaders continuous appearance novel invaders, threats difficulties pertaining aliens are continuously increasing. Furthermore, biological invasions change act concomitantly magnify each other's effect, which makes important study both phenomena collectively devise better approach mitigate their effects. This chapter offers general framework for understanding including fundamental background, process key hypotheses, consequences, future scenario.
