Phenotypic plasticity and genetic variation of Prosopis juliflora (Sw.) DC. across diverse rangelands in northeastern Ethiopia

Ecological Processes, Journal Year: 2025, Volume and Issue: 14(1)

Published: Jan. 10, 2025

Abstract Introduction Prosopis juliflora (Sw.) DC. substantially threatens dry rangelands due to its invasive attributes, exacerbated by climate change, land-use practices, and anthropogenic activities. Despite the urgent need understand ecological impacts, comprehensive studies examining relationship between functional traits reproductive fitness across diverse habitats scenarios are lacking. This study investigated of in Afar region Ethiopia, focusing on three types: dry-season grazing lands, wet-season wildlife reserves. Methods Plant samples were collected from 192 plots assess their adaptive potential genetic variation, alongside relevant physiographic climatic data. approach aims elucidate contributions these factors observed variation plasticity rangeland types differing land use intensity. Generalized linear mixed models co-occurrence networks employed analyze complex interaction. Results Our findings revealed significant fruiting onset duration, with lands demonstrating a shorter duration compared Genetic was for total seed mass number, indicating robust adaptability. The relative growth rate higher reserves highlighting advantages nutrient-rich environments. Additionally, analysis identified soil type as critical factor influencing trait performance. Conclusions underscores targeted management strategies mitigate impacts , emphasizing role nutrients fitness. offer valuable insights into dynamics species ecosystems inform conservation efforts.

Quantifying Competitive Fitness in Yeast with High‐Throughput Fluorescence Microscopy Imaging

Current Protocols, Journal Year: 2025, Volume and Issue: 5(1)

Published: Jan. 1, 2025

Abstract Competitive fitness is a fundamental concept in evolutionary biology that captures the ability of organisms to survive, reproduce, and compete for resources their environment. typically assessed lab by growing two or more competitors together measuring frequency each at multiple time points. Traditional microbial competitive assays are labor intensive involve plating on solid medium counting colonies. Here, we describe method quantitatively measure using fluorescence microscopic imaging machine‐learning‐enabled image analysis directly count number cells from competitor mixed population. This high‐throughput, primarily automated, efficient process gives accurate reproducible results fitness. entire process, sample preparation through microscopy quantification, provide instructions scripts analysis, calculations, data visualizations. © 2025 The Author(s).

Traits estimated when grown alone may underestimate the competitive advantage and invasiveness of exotic species

New Phytologist, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 1, 2024

Summary Functional differences between native and exotic species, estimated when species are grown alone or in mixtures, often used to predict the invasion risk of species. However, it remains elusive whether functional by two methods their ability invasiveness (e.g. high abundance) consistent. We compiled data from common garden experiments, which specific leaf area, height, aboveground biomass 64 invasive China were individually (pot) mixtures (field). Exotic accumulated higher than natives, but only field mixtures. Moreover, distinctiveness more predictive persistence relative abundance second year those alone. These findings suggest that assessing traits while may underestimate competitive advantage for some highlighting importance trait‐by‐environment interactions shaping invasion. Therefore, we propose integrating multi‐site multi‐year surveys manipulative experiments is required best identify key trait(s) environment(s) interactively shape community dynamics.

Variation in characteristics of leaf functional traits of alpine vegetation in the Three-River Headwaters Region, China

Ecological Indicators, Journal Year: 2022, Volume and Issue: 145, P. 109557 - 109557

Published: Oct. 19, 2022

Plant functional traits are adaptive formed by interactions between plants and the environment. Considering Three-River Headwaters Region as a case study, this study systematically analyzed relationship plant environmental factors in cold regions. The results show that there were significant differences among different vegetation types (herbs, shrubs, arbor plants). Leaf such leaf area (LA), length (LL), width (LW), circumference (LC), shape coefficient (SC) showed same trends herbs, plants. correlation of alpine regions shows unique growth mode their degree adaptation to environments ultimately determine trait variations. Moreover, was negative soil temperature nitrogen balance index (NBI), chlorophyll content (Chl), flavonoid (Flv), SC, whereas trend first increasing then decreasing temperature, LL (P < 0.05), LC 0.05). Similar herb shrub plants, also altitude There correlations NBI Chl Flv anthocyanin LA > 0.05) significantly positively correlated with altitude. Conversely, no LW We conclude climate play decisive role distribution at global scale, land use disturbances major regional topographic local characteristics.
