Plant functional traits couple with range size and shape in European trees

Abstract Aim Plant functional traits are frequently proposed as influential factors in species distribution. However, there is a gap assessing how plant resource‐economic relate to the size and shape of species' geographical range, what extent these relationships conserved over evolutionary history. Specifically, an acquisitive strategy (characterized by heightened metabolism, shorter lifespan quicker generation turnover) may promote isotropic range formations, resulting less elongated larger ranges. Here, I tested this link using data from 98 native European tree species. Location Palaearctic. Time period Present. Major taxa studied Trees. Methods used chorological maps quantify two independent attributes: area elongation. considered 28 linked resource‐use measured above‐ below‐ground organs. multi‐response phylogenetic mixed models calculate conservative trait correlation (CTC) phylogenetically (IND) component each with Results Range positively correlated resource strategies, while elongation strategies. This pattern was consistent across examined but statistically significant seven out traits, including specific leaf area, root mycorrhizal colonization.

Intricate Distribution Patterns of Six Cytotypes of Allium oleraceum at a Continental Scale: Niche Expansion and Innovation Followed by Niche Contraction With Increasing Ploidy Level

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Dec. 9, 2020

The establishment and success of polyploids are thought to often be facilitated by ecological niche differentiation from diploids. Unfortunately, most studies compared diploids polyploids, ignoring variation in ploidy level polyploids. To fill this gap, we performed a large-scale study 11,163 samples 1,283 populations the polyploid perennial geophyte

Here, we synthesize eco-evolutionary patterns found in range studies how knowledge of species ranges can inform our understanding conservation the face global change. We discuss whether general biogeographic “rules” reliable they be used to develop adaptive strategies native across their Rules considered include (1) factors that set limits promote shifts; (2) impact biotic interactions on limits; (3) abundance properties ranges; (4) gene flow implications for genetic rescue, (5) relationship between size risk. conclude by summarizing evaluating potential rules future management decisions. also outline areas research better understand capacity plants under environmental change govern advise conservationists extend work specifically consider peripheral novel populations, with a particular emphasis small Finally, call effort identify, synthesize, analyze prevailing or ecology help speed efforts.

The relationship between niche breadth and phylogenetic characteristics of eight species of rhubarb on the Qinghai‐Tibet Plateau, Asia

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(3)

Published: Feb. 29, 2024

The relationship between spatial distribution and phylogeny has been widely debated in recent decades. To understand biogeographic evolutionary history relationships to explore the interspecific similarities phylogenetic correlations of niche characteristics, we collected recorded all points for eight species rhubarb on Qinghai-Tibet Plateau, used different methods describe ecological niche, explored phylogeny, range. results reveal that: (1) ranges optimal environmental variables with close kinship are not exactly same, ecologically similar necessarily sister species, overlap no significant correlation phylogeny. Therefore, impact dimensions formation is greater than that geographical latitude rhubarb. (2) Among rhubarb, breadth positively correlated current suitable habitat area negatively fluctuations future area. In future, except

Plant interactions associated with a directional shift in the richness range size relationship during the Glacial-Holocene transition in the Arctic

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 28, 2025

Abstract A nearly ubiquitous negative relationship between taxonomic richness and mean range-size (average area of taxa) is observed across space. However, the complexity mechanism limits its applicability for conservation or range prediction. We explore whether holds over time, plant speciation, environmental heterogeneity, interactions are major factors within northeast Siberia Alaska. By analysing sedimentary ancient DNA from seven lakes, we reconstruct richness, biotic last 30,000 years. find positive to relationships during glacial period, shifting interglacial period. Our results indicate neither speciation nor heterogeneity principal driver. Network analyses show more which may contribute relationships. Conversely, in environment, result findings suggest potential susceptibility invasion but advantages far northern tundra given their interactions.
