Review of Invasive Plant Functional Traits and Management Using Remote Sensing in Sub-Saharan Africa

International Journal of Plant Biology, Journal Year: 2024, Volume and Issue: 15(2), P. 358 - 374

Published: April 28, 2024

Biodiversity and sustainable development in Sub-Saharan Africa (SSA) are considerably impacted by invasive alien plants (IAPs). Increasing plant invasions SSA threaten agricultural productivity, biodiversity conservation, other socioeconomic activities, which turn put the United Nations Sustainable Development Goals (SDGs) peril. In order to effectively combat IAPs, understanding their functional traits (morphological, physiological, phenological traits) integrating them into remote sensing (RS) is vital. While influence IAPs’ fitness invade establish a new geographical range, RS aids studying remotely, delineating mapping them, predicting potential invasions. The information on this study topic was gathered reviewing various existing studies published between 2000 2024. Based review, it deduced that majority of IAPs fast-growing (or acquisitive), with shorter leaf lifespan, bigger leaves, higher height, ultimately resulting resource acquisition ability. We established further SSA, there limited IAP integration RS. Many conducted region focus mostly distribution. Evidence from prior revealed trait (FTRS)-based research not only improves detection but also predicts whether certain can become or expand its distribution range. Thus, using FTRS approach could help management achieving SDGs. Our review discusses implications (e.g., Angola, Tanzania, Benin, Kenya, Uganda, Rwanda, Zambia, Burundi, Zimbabwe, Botswana, Malawi, etc.) for achievement SDGs; impact invasions; importance incorporating

Air temperature affects absorptive root traits, which are closely related to species distribution. However, it is still unclear how air regulates distribution through changes in traits. Seven functional traits of the roots 240 individuals 52 species, soil properties and were measured along an elevational gradient on Mt. Fanjingshan, Tongren City, Guizhou, then direct indirect effects these controls detected. Absorptive adapted with two strategies. The first strategy was positively associated specific area (SRA) length (SRL) negatively tissue density (RTD), representing classic economics spectrum (RES). second represented by trade-off between diameter, mycorrhizal fungi colonization (MF) SRL, collaboration "do yourself" resource uptake ranging from "outsourcing" uptake. regulated six ways: directly reducing importance value; indirectly increasing value nitrogen content or pH moisture inducing change absorption absorption; decreasing resulting turning into nutrient foraging traits; promoting conservation play a crucial role regulation multi-approaches temperature.

Tree Germination Sensitivity to Increasing Temperatures: A Global Meta‐Analysis Across Biomes, Species and Populations

ABSTRACT Aim Climate change is altering forest communities at an unprecedented pace. Current knowledge on trees' responses to climate shifts based mostly adults. Yet, germination traits and intraspecific variation can notably modulate species niches. This paper provides a quantitative review about warming effects tree species' germination, the role of population its implications under future climate.

Methods We reviewed 50 papers addressing 63 250 populations. Then, we conducted meta‐analysis assess percentage time, how modulated by seed origin. further evaluated populations' adaptation local temperature 27 Finally, estimated population‐based niches in eight these current conditions 2080 scenario (SSP5‐8.5).

Community Level Variation in Plant Leaf Traits along an Elevation Gradient in the Semi-Arid Mountains of Northwest China

Polish Journal of Ecology, Journal Year: 2023, Volume and Issue: 70(4)

Published: July 9, 2023

An elevation gradient affects temperature, precipitation, soil properties, and other environmental factors important for plant growth, resulting in differential responses of functional traits within between species. Here, three transect lines were established along an 1500 to 2900 m that spanned four vegetation types: desert grassland, low mountain shrub zone, subalpine coniferous forest, zone a semiarid ecosystem (western part the Helan Mountains, Northwest China). Nine — leaf nitrogen (LN), carbon (LC), thickness (LT), specific area (SLA), phosphorus, dry matter content, carbon/leaf (C/N), phosphorus (C/P), nitrogen/leaf (N/P) quantified investigate (1) how community-weighted means (CWM) unweighted (CM) vary; (2) inter- intraspecific (3) climate, topography properties affect at community level. We found with rising elevation, SLA LT increased then decreased, while C/P N/P showed opposite trend both CWM CM. Additionally, higher LN lower C/N zone. The CM no significant difference but close relationship them. Generally, all explained better by interspecific variation than variation, except N/P. covariance analysis indicated LP LC negative effects, whereas positive effects. contribution from altitude was slightly vapor pressure organic carbon.

Is intraspecific trait differentiation in Parthenium hysterophorus a consequence of hereditary factors and/or phenotypic plasticity?

Plant Diversity, Journal Year: 2022, Volume and Issue: 45(5), P. 611 - 620

Published: Sept. 10, 2022

Of the various strategies adopted by an invasive plant species for expanding its niche breadth, phenotypic differentiation (either due to plasticity and/or adaptive evolution) is proven be most successful. Lately, we studied persistence of substantial morpho-functional variations within individuals alien plant, Parthenium hysterophorus in Chandigarh, India, through field surveys. Based on observed differences, were categorized into two morphotypes, PA and PB. had higher leaf area, biomass, chlorophyll content as compared with However, PB a stem circumference, specific density, twig dry matter content, profuse branching, bigger canopy, better reproductive output than PA. To substantiate intraspecific P. deduce possible genesis these variations, propagated both morphotypes under experimental conditions winter summer. Apart from key differences during studies, protein carbohydrate metabolism leaves roots plants. Differences only early growth period, whereas traits varied mature flowering The effect season was highly significant all biochemical parameters (p ≤ 0.05). Parent (P) interactions between seasons significantly affected several analyses revealed that contrasting at time transplantation may regulate phenotype hysterophorus. pattern study justified consider morphotype biotype summer points towards role or combination genetic environmental (G × E) factors producing variability population

Seed dispersal of a fleshy‐fruited invasive shrub is affected by changes in the frugivorous bird assemblage along an elevational gradient

Austral Ecology, Journal Year: 2023, Volume and Issue: 48(8), P. 1797 - 1814

Published: Sept. 8, 2023

Abstract Seed dispersal by birds constitutes an essential mechanism for ornithochorous exotic plants to successfully invade a new system. New biotic associations with native might facilitate the upward spread of from foothills into high mountains. However, environmental changes associated elevation are known drive in bird assemblages, and it is not clear how impact seed service invaders. We evaluated frugivorous assemblages one shrubs ( Cotoneaster franchetii , Rosaceae) broadest range among woody invaders Córdoba Mountains (Argentina). quantified frugivory interactions (including absolute proportional fruit consumption dispersers, pulp consumers, predators) using 4‐h observations focal C. distributed across low‐elevation, mid‐elevation, high‐elevation sites (700, 1100, 1800 m a.s.l., respectively; 15 individuals per elevational band site elevation). disperser richness was highest at low‐ mid‐elevation (three species vs. site), but (39.1%, 88 seeds 7.7%, 20 low‐elevation). The Chiguanco Thrush Turdus chiguanco Turdidae) only found site. Fruit dispersers positively related their abundance elevation. In mountain system, single abundant generalist disperser, rather than species, can uphold effective invasive shrub. This pattern may such higher ranges, thereby promoting invasion other upper elevations.
