Samambaias e licófitas do município de Caxias, Maranhão, Brasil

open access: yesBoletim do Museu Paraense Emílio Goeldi - Ciências Naturais, 2010
O presente estudo refere-se ao inventário das samambaias e licófitas do município de Caxias (Maranhão, Brasil), representando um segundo trabalho com estes grupos de plantas no estado. Considerando que são plantas pouco inventariadas no Maranhão, compreendemos ser de importância o estudo da sua composição florística para o conhecimento da diversidade ...

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic ...

“Dark taxonomy”: A new protocol for overcoming the taxonomic impediments for dark taxa and broadening the taxon base for biodiversity assessment

open access: yesCladistics, Volume 41, Issue 2, Page 223-238, April 2025.
Abstract We are entering the sixth mass extinction with little data for “dark taxa”, although they comprise most species. Much of the neglect is due to the fact that conventional taxonomic methods struggle with handling thousands of specimens belonging to hundreds of species. We thus here propose a new strategy that we call “dark taxonomy”.

GIS‐based G × E modeling of maize hybrids through enviromic markers engineering

open access: yesNew Phytologist, Volume 245, Issue 1, Page 102-116, January 2025.
Summary Through enviromics, precision breeding leverages innovative geotechnologies to customize crop varieties to specific environments, potentially improving both crop yield and genetic selection gains. In Brazil's four southernmost states, data from 183 distinct geographic field trials (also accounting for 2017–2021) covered information on 164 ...

Unlocking renewable energy potential: A case study of solar and wind site selection in the Kasserine region, central‐western Tunisia

open access: yesEnergy Science &Engineering, Volume 12, Issue 3, Page 771-792, March 2024.
Abstract Developing wind and solar photovoltaics on a large scale requires substantial financial investments, making it crucial to identify the most suitable locations beforehand. To address this issue, a spatial analysis is carried out to determine the most potential sites for hosting large‐scale solar photovoltaic and wind systems in the region of ...

Potencial ornamental de samambaias e licófitas no Leste do Maranhão, Brasil

open access: yesResearch, Society and Development, 2020
A identificação do potencial ornamental de plantas tem crescido nos últimos anos, sendo uma tendência mundial, mas ainda pouco desenvolvida no Brasil, onde o conhecimento sobre essa diversidade é incipiente. As samambaias e licófitas constituem um grupo heterogêneo, com uma diversidade de habitat e variações morfológicas que as proporcionam um forte ...

The Weight of Genetic Drift: A Pedigree‐Based Evaluation of the Breton Horse Population in Brazil

open access: yesVeterinary Medicine International, Volume 2024, Issue 1, 2024.
The genetic diversity of Breton horses in Brazil is a critical concern, mainly due to the small population size and low number of births per year. Given that the inbreeding was overlooked by breeders for multiple generations, we estimated the genetic diversity of this population utilizing pedigree‐based measures of population diversity. A total of 1394
