Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Cactaceae Juss.

open access: yes, 2022
The relevance of classifying the Cactaceae family into different subfamilies helps to better understand the subdivision into clades that differ morphologically (see key below). On the other hand, the delimitation of some subfamilies has shown to been difficult (for example the paraphyly of the Pereskioideae K.Schum. and the ambiguous relationships of

EVOLUTION OF THE CHOLLAS (CACTACEAE)

open access: yesMadroño, 2021
Cacti with the common name cholla are classified into several genera of the subfamily Opuntioideae (Cactaceae), and appear to be a monophyletic group. Although recent studies have provided strong resolution of the base of this group, assessment of evolutionary processes within genera have been limited due to taxon sampling.

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Morphological variation in Opuntia jaliscana (Cactaceae)

open access: yesAnales del Jardín Botánico de Madrid, 2017
The aim of this study was to describe morphological variations of Opuntia jaliscana in 5 wild populations in the state of Jalisco (Mexico). Populations were selected along an environmental aridity gradient, and 61 vegetative and reproductive characters ...

Population‐Specific Chemotypes in Pseudomisopates rivas‐martinezii (Sanchez Mata) Güemes From La Serrota and Gredos Massifs (Iberian Central Range)

open access: yesChemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Pseudomisopates rivas‐martinezii, a critically endangered Iberian endemic, reveals population‐specific chemotypes when analyzed by elemental analysis, FTIR, and GC–MS. Underground tissues from both populations share a convergent histidine‐derived metabolite profile, whereas aerial parts diverge markedly: La Serrota accumulates phenolic derivatives from

From passion to illegality: Understanding succulent consumers' decision to participate in the illegal online wildlife trade

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1773-1784, June 2026.
Abstract The illegal wildlife trade represents a significant threat to biodiversity. Limited research has examined the illegal trade in succulents, plants characterized by their ability to store water in their leaves, stems or roots. The growing popularity of succulents has contributed to the emergence of illicit consumer practices.

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...
