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.

Floristics in Mexico today: insights into a better understanding of biodiversity in a megadiverse country

Botanical Sciences, Journal Year: 2022, Volume and Issue: 100(Special), P. S14 - S33

Published: Aug. 17, 2022

Advancing our current knowledge on floristic richness in Mexico requires access to different sources, including published and unpublished inventories, fascicles of ongoing projects, publicly available online databases. The evaluation these sources reveals how extensive the information country’s diversity is, its heterogeneity, lack protocols standards for proper organization, analysis, synthesis. This review addresses extent which provide basis achieve long-awaited goal completing Flora Mexico, traditional outputs taxonomic work (Floras checklists) are useful other fields biological research. We identified major gaps, as well actual potential uses by scholars public. Although all reviewed focus a better Mexican plant species, each one has own approach, geographic coverage, objectives, producing incompatibilities that hamper their integration rapid efficient synthesis analysis. Such should offer an updated scenario geographical setting foundations organized strategies aimed complete short term. Floristic country continues advance actively, indicated growing number inventories buildup shows much we know today about Mexico’s vascular highlights relevance this study nature, particularly those related component.

Improving species delimitation for effective conservation: a case study in the endemic maple‐leaf oak (Quercus acerifolia)

New Phytologist, Journal Year: 2023, Volume and Issue: 238(3), P. 1278 - 1293

Published: Jan. 28, 2023

Summary Species delimitation is challenging in lineages that exhibit both high plasticity and introgression. This challenge can be compounded by collection biases, which may downweight specimens morphologically intermediate between traditional species. Additionally, mismatch named species observable phenotypes compromise conservation. We studied the boundaries of Quercus acerifolia , a tree endemic to Arkansas, U.S. performed morphometric analyses leaves acorns from 527 field 138 herbarium samples Q. its close relatives, shumardii rubra . employed two novel approaches: sampling ex situ collections detect phenotypic caused environmental variation comparing random with historical identify biases might undermine delimitation. To provide genetic evidence, we also molecular on genome‐wide SNPs. shows distinctive morphological, ecological, genomic characteristics, rejecting hypothesis variant found mismatches taxonomy clusters. detected underrepresentation morphological intermediates collections, bias discovery recognition. Rare conservation requires considering addressing taxonomic problems related plasticity, clusters, biases.

Mobilisation of Data From Natural History Collections Can Increase the Quality and Coverage of Biodiversity Information

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: April 1, 2025

ABSTRACT The surge of biodiversity data availability in recent decades has allowed researchers to ask questions on previously unthinkable scales, but knowledge gaps still remain. In this study, we aim quantify potential gains insect the Global Biodiversity Information Facility (GBIF) through further digitisation natural history collections, assess what degree would fill biases spatial and environmental record coverage, deepen understanding bias with regard climate rarity. Using mainland Afrotropical records for Catharsius Hope, 1837 (Coleoptera: Scarabaeidae), compared inventory completeness GBIF a dataset which combined these from taxonomic revision. We analysed how improved reduced regional distribution occurrence using an approach that identifies well‐surveyed units 100 × 100km as well emerging techniques classify rarity climates. found number cells could be calculated, coverage types by ‘well‐sampled’ cells, increased threefold when set set. Improvements sampling Central Western Africa were particularly striking, rare climates was similarly improved, not single well‐sampled cell alone occurred rarest types. These findings support existing literature suggests are pervasive, especially insects tropics, so, is yet ready serve standalone source all taxa. However, show collections hold necessary information many gaps, their should priority.

Target sequence capture of Barnadesioideae (Compositae) demonstrates the utility of low coverage loci in phylogenomic analyses

Molecular Phylogenetics and Evolution, Journal Year: 2022, Volume and Issue: 169, P. 107432 - 107432

Published: Feb. 4, 2022

Target sequence capture has emerged as a powerful method to hundreds or thousands of genomic regions in cost- and time-efficient approach. In most cases, however, targeted lack full information for certain samples, due taxonomic, laboratory, stochastic factors. Loci lacking molecular data large number samples are commonly excluded from downstream analyses, even though they may still contain valuable information. On the other hand, including data-poor loci bias phylogenetic analyses. Here we use target dataset an ecologically taxonomically diverse group spiny sunflowers (Asteraceae, Compositae: Barnadesioideae) test how inclusion exclusion such affects inference. We investigate sensitivity concatenation coalescent approaches missing with matrices varying taxonomic completeness by filtering different proportions prior analysis. find that affect both topology branch support resulting phylogenies. The matrix containing all yielded overall highest node values, independently amount nucleotides. These results provide empirical earlier suggestions based on single genes simulations taxa high amounts should not be readily dismissed can essential phylogenomic reconstruction.
