Does climate influence genome size diversity? A study of genome size-environment associations across the Madagascar grass flora

Joseph Morton
Repetitive DNA accumulation and whole genome duplication are common across angiosperm lineages, resulting in some of the largest ever-recorded genomes, yet the majority of angiosperm species have small genomes. This suggests selection may be acting to reduce genome size (GS), and there is growing evidence of environmental factors influencing GS diversity. This paper examines this relationship using a dataset of ecologically diverse Malagasy Poaceae across wide environmental gradients. Flow cytometry was used to estimate 1C-values...

Novel insight into genome size and succulent trait evolution in Aloe (Asphodelaceae)

Kelda Elliott
Through the evaluation of genomic, anatomical, and physiological characters against the most taxa rich phylogenetic hypothesis of the genus Aloe, this research elucidated succulent trait evolution and relationships governing the ‘succulence syndrome’ within this iconic group. Genome size estimates for 110 species produced 2.7-fold 1C variation and range of 13.49-36.42 (pg) and 1.7-fold 1Cx variation and range of 13.49-22.52 (pg), which demonstrates, whole genome duplication is responsible for the majority of genome size variation in...

Can a change in taxonomy help protect species?

Paloma Moore
The genus Pterocarpus contains some of the world’s most heavily traded rosewood species. Presently, three Asian and two African Pterocarpus species are listed as threatened on The IUCN Red List of Threatened Species. Pterocarpus rohrii Vahl is a highly variable species, distributed throughout Central and South America. A recent taxonomic revision of the P. rohrii complex resulted in the reclassification of 588 herbarium records, previously identified as P. rohrii but now recognised to represent 10...

Explaining barkcloth properties through plant anatomy

Roberto Saad
Barkcloth, a material derived from the beaten inner bark of plants, is an ancient textile of widespread origins, recorded in Africa, South America, Europe, Asia, and Oceania, especially the Polynesian Islands. An antiquated craft, the practice of making barkcloth is kept alive by the cultural and spiritual significance it retains in some places, as well as a small commercial demand for it. All barkcloths are manufactured from the bast fibres of a plant’s stem. Historically,...

Revision of Chassalia (Rubiaceae) in Borneo

Tianyi Yu
The genus Chassalia in Borneo is revised based on a morphological survey of herbarium specimens using classical taxonomic methods. The tribal placement and probable paraphyly of Chassaliaas currently delimited is reviewed. Previously four described species of Chassalia were known from Borneo with only one endemic species Chassalia psychotrioides . 12 new species are described in this study, all of them endemic to Borneo. A key is given to the 16 species of the genus now...

UK National Tree Seed Project Seed Collecting Manual

Simon Kallow
The UK National Tree Seed Project (UKNTSP) welcomes partners and volunteers to collect seed samples of nationally important trees and shrubs from across their UK range. This project will build a national ex situ collection of UK tree seed, maintained and managed by the Millennium Seed Bank (MSB). The collection will be genetically comprehensive and comprise sufficient seeds to support research and conservation, in order to meet the challenges facing UK forests. This guide has...

Madagascar Grass Atlas

Linah Rabarivola, Henintsoa Razanajatovo, Velosoa Razafiniary, Andriambolantsoa Rasolohery, Hélène Ralimanana & Maria S. Vorontsova
Madagascar has a unique heritage in terms of biodiversity. Its separation from Africa set the backdrop for the unique evolution of its flora and fauna. Its isolated island nature gave rise to high endemism and explosive speciation. Of its estimated 12,000 vascular plant species, 83% are unique to Madagascar (Madagascar Catalogue, 2019). Its richness in ecosystems and biodiversity have led to its classification as a megabiodiverse country (Mittermeier et al, 2007). Madagascar is home to...

Revisiting generic concepts in the Teloschistaceae (lichenforming Ascomycota) using molecular phylogenetics, algorithmic taxa delimitation and molecular networks

Theo Llewellyn
In systematics, genera delimitation is constantly changing as taxonomic units above species level are not standardised. The Teloschistaceae, a diverse family of lichenised fungi, represents an extreme example of this where the number of genera has increased tenfold in the last decade. Many of these genera are based solely on molecular clades which makes the current classification confusing for taxonomists and impenetrable for non-experts. As a result, no widely accepted classification exists, and most people...

Biogeography and conservation status of the endangered species Varronia bellonis

Anthony Maldonado Castro
Varronia bellonis (Boraginaceae) is a threatened (Critically Endangered) species, endemic to the Caribbean island of Puerto Rico where it’s restricted to the island’s western and central-north regions. Ongoing international collaboration is researching key aspects of the species phylogenetic placement, biogeography and conservation status to inform its conservation. Desk and field-based studies have provided the data (occurrence records, geology and land cover maps, protected area boundaries) necessary to develop a GIS and enable the study of...

Contributions towards the consistent ID of powdery mildew (Erysiphales, Ascomycota) species

Brandon Shaw
Powdery mildews (Erysiphales, Ascomycota) are an order of plant pathogenic fungi that infect 10,000 different angiosperm species, including important crop species. Traditional morphological methods of identifying powdery mildews can be difficult and time consuming, as different character states can be hard to distinguish. Molecular techniques using the ITS region fail to provide a species level identification 1 out of every 4 times and often must be used in conjunction with morphology to provide an identification...

Habitats Menacés et Zones Tropicales Importantes Pour les Plantes (ZTIP) de Guinée, Afrique de l'Ouest

Charlotte Couch, Martin Cheek, Pépé Haba, Denise Molmou, Jenny Williams, Sékou Magassouba, Saïdou Doumbouya & Muhammad Yaya Diallo
La Guinée compte plus de 250 espèces répertoriées de plantes uniques et menacées, plus que tout autre pays d'Afrique de l'Ouest. Assurer leur protection ne devrait pas uniquement être une priorité nationale, mais une priorité mondiale. Parmi ces espèces – ces ressources naturelles – il existe potentiellement de nouveaux médicaments, matériaux, et aliments qui, grâce à la recherche scientifique, pourraient améliorer les moyens de subsistance des Guinéens. Cependant, le temps presse. Déjà 35 des espèces...
