Defining the pyro‐thermal niche: do seed traits, ecosystem type and phylogeny influence thermal thresholds in seeds with physical dormancy?

open access: yesNew Phytologist, Volume 246, Issue 4, Page 1567-1582, May 2025.
Summary Seeds are a key pathway for plant population recovery following disturbance. To prevent germination during unsuitable conditions, most species produce dormant seeds. In fire‐prone regions, physical dormancy (PY) enables seeds to germinate after fire. The pyro‐thermal niche, incorporating temperature effects into seed dormancy and mortality, has

Phylogenetic diversity and biodiversity indices on phylogenetic networks

open access: yes, 2018
In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their ...

Sex‐Specific Ultraviolet Radiation Tolerance Across Drosophila

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
This study investigates the genetic basis of phenotypic differences between two species of Drosophila, D. santomea and D. yakuba, focusing on their adaptation to UV tolerance and stress. Genomic and empirical evidence shows that island populations of D.

Imprints of land use history and disturbance regime in phylogenetic diversity of Mediterranean plant communities

open access: yesEcosphere, Volume 15, Issue 8, August 2024.
Abstract Mediterranean landscapes were drastically affected by high levels of abandonment of agricultural and other land practices during the last century. These changes in land use can have significant effects on diversity patterns by altering disturbance and competition equilibria within plant communities at the landscape level.

Environmental conditions do not predict diversification rates in the Bantu languages [PDF]

open access: yes, 2019
The global distribution of language diversity mirrors that of several variables related to ecosystem productivity. It has been argued that this is driven by the size of social networks, which tend to be larger in harsher climates to ensure food security,

Biogeographic affiliation and centers of richness as predictors of elevational range‐size patterns for Malesian flora

open access: yesEcography, Volume 2024, Issue 5, May 2024.
Our goal was to interrogate the idea that “mountain passes are higher in the tropics” by investigating ecological and biogeographic drivers of elevational range‐sizes patterns among equatorial flora. We used herbarium records for 60 species‐rich plant families, representing 18 535 species total, to estimate distributions over a 4500 m elevational ...

A review of Leptospermum scoparium (Myrtaceae) in New Zealand [PDF]

open access: yes, 2005
Information about Leptospermum scoparium (Myrtaceae), the most widespread and important New Zealand indigenous shrub species, is reviewed. L. scoparium is a variable species, requiring more study of the genetically based differences between New Zealand ...

Reassessment of the enigmatic “Prestosuchus” loricatus (Archosauria: Pseudosuchia) from the Middle‐Late Triassic of southern Brazil

open access: yesThe Anatomical Record, Volume 307, Issue 4, Page 974-1000, April 2024.
Abstract Our knowledge of the diversity and evolution of South American Triassic pseudosuchians has greatly improved in the past 15 years, due to new discoveries, but also to the revision of several historically important specimens. One of the earliest descriptions of pseudosuchians from the Triassic of Brazil stems from the classic work of Huene from ...

Molecular Characterization of a Poly-β-Hydroxybutyrate-Producing Microbacterium Isolate

open access: yes, 2015
Bacterial poly-β-hydroxybutyrate (PHB) is a natural, biodegradable polymer, which is accumulated in the cells as an energy reserve materialdue to depletion of nitrogen or phosphorous in the presence of excess carbon source.
