Abstract Discoveries from collections‐based science change the way we perceive ourselves, our environment, and place in universe. The 18 th Century saw beginning of formal classification with Linnaeus proposing a system to classify all life. 19 ushered age exploration as naturalists undertook large‐scale collecting expeditions leading major scientific advances (the founding Physical Geography, Meteorology, Ecology, Biogeography, Evolution) challenging long held beliefs about nature. In 20 collections were central paradigm shifts, including theories Continental Drift Phylogenetic Systematics; Molecular Phylogenetics added testable hypotheses, computerized specimen records gave rise field Biodiversity. first 15 years 21 st have seen tree‐thinking pervade life sciences, emergence Evolutionary Medicine, new Food Safety methods. More are on way: (i) Open access large amounts data & images, (ii) Linking climate phylogenies global scale, (iii) Production vast quantities genomic allowing us address big evolutionary questions. As result people see themselves not center things but rather part complex It is essential that integrate discoveries knowledge past (e.g., collections) order understand this planet inhabit.

Towards a multisensor station for automated biodiversity monitoring

Basic and Applied Ecology, Год журнала: 2022, Номер 59, С. 105 - 138

Опубликована: Янв. 7, 2022

Rapid changes of the biosphere observed in recent years are caused by both small and large scale drivers, like shifts temperature, transformations land-use, or energy budget systems. While latter processes easily quantifiable, documentation loss biodiversity community structure is more difficult. Changes organismal abundance diversity barely documented. Censuses species usually fragmentary inferred often spatially, temporally ecologically unsatisfactory simple lists for individual study sites. Thus, detrimental global their drivers remain unrevealed. A major impediment to monitoring lack human taxonomic expertise that implicitly required large-scale fine-grained assessments. Another amount personnel associated costs needed cover scales, inaccessibility remote but nonetheless affected areas. To overcome these limitations we propose a network Automated Multisensor stations Monitoring Diversity (AMMODs) pave way new generation assessment centers. This combines cutting-edge technologies with informatics expert systems conserve knowledge. Each AMMOD station autonomous samplers insects, pollen spores, audio recorders vocalizing animals, sensors volatile organic compounds emitted plants (pVOCs) camera traps mammals invertebrates. AMMODs largely self-containing have ability pre-process data (e.g. noise filtering) prior transmission receiver storage, integration analyses. Installation on sites difficult access require sophisticated challenging system design optimum balance between power requirements, bandwidth transmission, service, operation under all environmental conditions years. An important prerequisite automated identification databases DNA barcodes, animal sounds, pVOCs, images used as training identification. thus become key component advance field research policy delivering at an unprecedented spatial temporal resolution.

Опубликована: Фев. 1, 2024

Plants have been an essential source of human medicine for millennia. In this review, we argue that a holistic, interdisciplinary approach to the study medicinal plants combines methods and insights from three key disciplines - evolutionary ecology, molecular biology/biochemistry, ethnopharmacology is poised facilitate new breakthroughs in science, including pharmacological discoveries rapid advancements health well-being. Such research leverages data spanning space, time, species associated with plant evolution, genomics, metabolomic trait diversity, all which build heavily on traditional Indigenous knowledge. contrasts sharply most well-funded successful during last half-century, which, despite notable advancements, has greatly oversimplified dynamic relationships between humans, kept hidden larger narratives about these relationships, overlooked potentially important into life-saving medicines. We suggest people should be viewed as partners whose relationship involves complicated poorly explored set (socio-)ecological interactions not only domestication but also commensalisms mutualisms. short, are just chemical factories extraction exploitation. Rather, they may symbiotic shaped modern societies, improved health, extended lifespans.

Testing genome skimming for species discrimination in the large and taxonomically difficult genus Rhododendron

Molecular Ecology Resources, Год журнала: 2021, Номер 22(1), С. 404 - 414

Опубликована: Июль 26, 2021

Standard plant DNA barcodes based on 2-3 plastid regions, and nrDNA ITS show variable levels of resolution, fail to discriminate among species in many groups. Genome skimming recover complete genome sequences arrays has been proposed as a solution address these resolution limitations. However, few studies have empirically tested what gains are achieved practice. Of particular interest is whether adding substantially more characters will lead an increase discriminatory power, or the limitations standard fundamentally due genomes not tracking boundaries. To this, we used near-complete nuclear ribosomal from Rhododendron compared discrimination success with barcodes. We sampled 218 individuals representing 145 this species-rich taxonomically difficult genus, focusing global biodiversity hotspots Himalaya-Hengduan Mountains. Only 33% were distinguished using ITS+matK+rbcL+trnH-psbA. In contrast, 55% sequences. The vast majority additional characters. Thus, despite previous showing asymptote beyond 3-4 results that demonstrable power possible extensive data. gains, remain unresolved, also reinforce need access multiple unlinked loci obtain transformative plants.
