Automatic Identification of Ivorian Plants from Herbarium Specimens using Deep Learning

International Journal of Emerging Technology and Advanced Engineering, 2022
— Plant identification is most often based on visual observations by botanists and systematists. Deep learning has become a tool that provides an alternative to automatic plant identification. Our study consists in implementing a method for plant recognition from herbarium specimens using deep learning classification methods.

The Use of Leap in Herbarium Management and Plant Biodiversity Research

Journal of East African Natural History, 1996
The List of East African Plants (LEAP) is an electronic database of the species, subspecies, and varieties of vascular plants (angiosperms, gynmosperms, ferns, and fern allies) that are native or naturalised in East Africa (Uganda, Kenya, and Tanzania).

Prioritizing regionally rare plant species for conservation using herbarium data

Biodiversity and Conservation, 2013
Because the conservation of biodiversity occurs under time and resource constraints, it is necessary to prioritize species most deserving of attention. Natural history collections have been identified as a valuable source of information in applied conservation practice, particularly for species-rich taxa like plants.

Diversity and use of plant collections of the Lagos University Herbarium, Nigeria

Feddes Repertorium
AbstractThis study aimed to gain insights into the diversity and use of the collections of the Lagos University Herbarium (LUH), Nigeria. A total of 1509 species representing 188 plant families in 57 plant orders were recorded. This comprises dicotyledons (1260); monocotyledons (217); ferns (29); moss (1); conifers (1); and macro algae (1).

Defining conservation priorities for plant taxa in southeastern New Brunswick, Canada using herbarium records

Biological Conservation, 1998
Biological databases are needed for the development of ecologically sensitive land management strategies. Quantitative information that would serve this purpose is typically unavailable or limited to a few species. An alternative is qualitative herbarium data. While often collected unsystematically, herbarium records are usually available for many taxa.

THE ROLE OF HERBARIA AND FLORA IN PRESERVING LOCAL PLANT-USE INFORMATION: THE CASE OF THE ETHIOPIAN NATIONAL HERBARIUM AND FLORA

Journal of East African Natural History, 2005
The aim of this study was to compile and analyse information on local use of plants in Ethiopia based on data obtained from labels of specimens stored at the National Herbarium and from published volumes of the Flora of Ethiopia and Eritrea. Two families were considered: Fabaceae and Euphorbiaceae.

The potential for the use of herbarium specimens to determine the host plants of Ceutorhynchus (Coleoptera: Curculionidae)

The Canadian Entomologist, 2015
AbstractThe host plants of native Ceutorhynchus Germar (Coleoptera: Curculionidae) species are poorly known in North America, and knowledge of these is essential for biological control programmes involving this genus of weevils. We hypothesised that weevil larva emergence holes on plant specimens in herbarium collections might reveal potential plant ...

Ready-to-use DNA extracted with a CTAB method adapted for herbarium specimens and mucilaginous plant tissue

Plant Molecular Biology Reporter, 2006
This report summarizes major changes in previously published protocols for DNA extraction to improve the quality of DNA extracted from plants. Here, we highlight the critical modifications in the original protocols. The efficiency of these changes results in high-quality DNA ready to use in a variety of phytogenetically distant plant families, in ...

Using herbarium genomics to understand the history of a global plant invasion

Abstract Invasive plants are dynamic eco-evolutionary systems characterized by rapid spread and evolutionary change. Herbarium genomics offers a powerful way to study these processes across broad spatial and temporal scales. We generated low-coverage shotgun-sequencing data from 152 herbarium specimens of the invasive

Accelerating plant DNA barcode reference library construction using herbarium specimens: improved experimental techniques

Molecular Ecology Resources, 2015
AbstractA well‐covered reference library is crucial for successful identification of species by DNA barcoding. The biggest difficulty in building such a reference library is the lack of materials of organisms. Herbarium collections are potentially an enormous resource of materials. In this study, we demonstrate that it is likely to build such reference
