Tracking hidden dimensions of plant biogeography from herbaria

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Plants are diverse, but investigating their ecology and evolution in nature across geographic temporal scales to predict how species will respond global change is challenging. With breadth, herbarium data provide physical evidence of the existence a place time. The remarkable size collections along with growing digitization efforts around world possibility extracting functional traits from preserved plant specimens makes them invaluable resources for advancing our understanding changing distributions over time, biogeography, conserving communities. Here, I synthesize core aspects biogeography that can be gleaned herbaria distributions, attributes (functional biogeography), conservation globe. advocate collaborative, multisite, multispecies research harness full potential these while addressing inherent challenges using macroecological investigations. Ultimately, present untapped opportunities enable predictions species' responses inform effective planning.

A new classification system and taxonomic synopsis for Malpighiaceae (Malpighiales, Rosids) based on molecular phylogenetics, morphology, palynology, and chemistry

Malpighiaceae has undergone unprecedented changes in its traditional classification the past two decades due to several phylogenetic studies shedding light on non-monophyly of all subfamilies and most tribes genera. Even though morphological characters were used reconstruct last molecular generic phylogeny Malpighiaceae, a new system never been proposed for this family. Based comprehensive review twenty years published family, we propose provide taxonomic synopsis based phylogenetics, morphology, palynology, chemistry as baseline systematics, conservation, taxonomy family worldwide. currently comprises (Byrsonimoideae Malpighioideae), 12 ( Acmanthereae , Acridocarpeae trib. nov.

Plant extinction in the Anthropocene

Botanical Journal of the Linnean Society, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 28, 2024

Abstract Species go extinct each day, most without notice. The current human-induced extinction rate is up to 700 times higher than the background rate. Extinctions are not different for plants, animals, or fungi, although botanical and invertebrate extinctions much more poorly documented those of charismatic vertebrates. In a recent book on plants (Christenhusz & Govaerts, 2023), an overview since 1753 was presented, listing which species became probable reason their extinction. As have date when they were last documented, timeline can also be compiled based these data. This shows increase from 1890 1940, but decline in new recorded after 1980s, likely result taxonomic impediment. Extinction rates before 1800 impacted by lack data (here named Berkeley extinction). It concluded that highest biodiversity-rich areas with high human influence (extinction hotspots). Two combinations name proposed here, showing importance taxonomy conservation. Although anthropogenic plant global phenomenon, particular concern Hawaiian Islands, southern Africa, Australia, Indian Subcontinent, Southeast Asia, Brazil. been mainly caused land clearing agriculture urbanization, invasive feral mining, river dams, diseases, poaching. We predict unusual weather patterns associated rapid climate change may extinctions.

Successful reintroduction cannot guaranteed. costly usually dependent short-term funding, efforts vain. Protection natural cost-effective long term.

Genome size is positively correlated with extinction risk in herbaceous angiosperms

New Phytologist, Journal Year: 2024, Volume and Issue: 243(6), P. 2470 - 2485

Published: July 30, 2024

Angiosperms with large genomes experience nuclear-, cellular-, and organism-level constraints that may limit their phenotypic plasticity ecological niche, which could increase risk of extinction. Therefore, we test the hypotheses large-genomed species are more likely to be threatened extinction than those small genomes, effect genome size varies across three selected covariates: life form, endemism, climatic zone. We collated information for a representative sample angiosperms comprising 3250 species, analyzed alongside zone variables using phylogenetic framework. Genome is positively correlated risk, pattern driven by signal in herbaceous but not woody regardless climate endemism. The influence stronger endemic relatively homogenous different climates. Beyond its indirect link via endemism climate, associated directly significantly. serve as proxy difficult-to-measure parameters resilience vulnerability angiosperms. it merits further exploration useful biological attribute understanding intrinsic augmenting plant conservation efforts.

Pulsatilla patens (L.) Mill. (Eastern pasque flower) is classified as a highly endangered and declining species in Europe. The present research assessed the current status of P.

We aimed to analyze relationships between populations size, demographic indicators, soil parameters, order gain knowledge impact local ecological factors optimal growth conditions, which are important for conservation potential reintroduction. Although was not detected more than third surveyed 624 locations, 18 thousand individuals were recorded. Our results indicate that conditions occurred near highways, forest roads, paths, is, places with reduced competition from improved lighting conditions. seed viability ranging 22% 62% can be considered potentially sufficient continuation if enough flowering plants moss-free spaces germination maintained. tolerates broad pH range, this mainly grows acidic sandy soils an average pHKCl 4.07. parameters most strongly positively correlated regional population size performance included higher level plant available nutrient content, particularly P, K, Ca, Mg, Mn B. Increased P levels significantly enhanced flowering, while high organic matter content could associated sizes. Despite still large population, long-term risks remain without active management. Conservation measures, such creating open where vegetation removed shading reduced, necessary mitigate decline.
