Plastid genome structure and phylogenomics of the freshwater red algal order Batrachospermales (Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract For the freshwater red algal order Batrachospermales, the number of plastid genomes available is relatively small compared to the number of genera. Fully assembled plastid genomes can provide insights into plastid evolution and crucial data for phylogenetic reconstruction.

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate. [PDF]

open access: yesJ Exp Zool B Mol Dev Evol
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

Development of a functional approach in a grassland vegetation sub-model = Desenvolvimento de uma abordagem funcional em um submodelo vegetal campestre

open access: yesActa Scientiarum: Animal Sciences, 2008
To improve our understanding of grassland dynamics under different levels of utilization, a functional description of the vegetation was introduced in a deterministic model. The selected traits and their parameterization were based on the results of a longtermexperiment in which temperate grasslands were managed for 12 years with three levels of ...

Método fitossociológico de Braun-Blanquet ou clássico sigmatista (análise da vegetação). [PDF]

open access: yes, 2011
A paisagem é um termo muito utilizado, quer na linguagem científica ou técnica, quer no dia-a-dia. Foi a partir do meado do séc. XIX, que a paisagem se tornou objecto de estudo científico, a par da concepção artística.

Faunistic inventory of the genus Culicoides (Diptera: Ceratopogonidae) in Mauritius Island, Indian Ocean: Diversity and spatial distribution of species of veterinary interest Inventaire faunistique du genre Culicoides (Diptera: Ceratopogonidae) sur l'île Maurice dans l'océan Indien: diversité et répartition spatiale des espèces présentant un intérêt vétérinaire

open access: yesMedical and Veterinary Entomology, EarlyView.
Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, EarlyView.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

A chromosome‐scale genome assembly of Hordeum erectifolium: genomic, transcriptomic and anatomical adaptations to drought in a wild barley relative

open access: yesNew Phytologist, EarlyView.
Summary Wild crop relatives are valuable genetic resources for improving stress adaptation in cultivated species, but their effective use depends on high‐quality reference genomes integrated with phenotypic and molecular datasets. Hordeum erectifolium, a wild relative of barley (H.
