Chromosome-scale reference genome of <i>Pectocarya recurvata</i>, the species with the smallest reported genome size in Boraginaceae. [PDF]

open access: yesAppl Plant Sci
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

Indução de florescimento precoce em angiospermas arbóreas: perspectiva de uso da técnica em espécies da Mata Atlântica

open access: yesBiotemas, 2001
A prolongada duração da fase juvenil dificulta a obtenção de sementes para a propagação em diversas angiospermas lenhosas da Mata Atlântica, prejudicando o combate à perda de biodiversidade nesse ecosistema.

Recurrent marine heatwaves threaten the resilience and viability of a key Mediterranean octocoral species

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1161-1174, November 2023., 2023
Abstract Long‐term ecological studies are essential for understanding the resilience of temperate reefs to ocean warming and the response of their habitat‐forming species to recurrent marine heatwaves (MHWs). This study evaluated the long‐term response (2005–2021) of the habitat‐forming octocoral Eunicella singularis (Esper, 1791) to recurrent MHWs in ...

Migratory geese allow plants to disperse to cooler latitudes across the ocean

open access: yesJournal of Biogeography, Volume 50, Issue 9, Page 1602-1614, September 2023., 2023
Abstract Aim How plants can disperse in response to global change is a critical question, yet major knowledge gaps persist about long‐distance dispersal (LDD) mechanisms. We studied the potential a migratory waterfowl has for LDD of flowering plants via gut passage of seeds (endozoochory), comparing spring and autumn migration.

Parasitic flowering plant collections embody the extended specimen

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 319-331, February 2023., 2023
Abstract The widespread digitization of natural history collections, combined with novel tools and approaches is revolutionizing biodiversity science. The ‘extended specimen’ concept advocates a more holistic approach in which a specimen is framed as a diverse stream of interconnected data.

Rapid evolution of a floral trait following acquisition of novel pollinators

open access: yesJournal of Ecology, Volume 109, Issue 5, Page 2234-2246, May 2021., 2021
We test whether the acquisition of a new pollinator functional group (hummingbirds) can lead to rapid evolution of flowers after the recent trans‐continental range expansion of Digitalis purpurea. In naturalised populations in two separate regions in the Americas, we found convergent changes and strong selection for larger proximal corolla tubes, a ...

Phylogenetic and ecological correlates of pollen morphological diversity in a Neotropical rainforest

open access: yesBiotropica, Volume 53, Issue 1, Page 74-85, January 2021., 2021
Abstract Morphology varies enormously across clades, and the morphology of a trait may reflect ecological function or the retention of ancestral features. We examine the tension between ecological and phylogenetic correlates of morphological diversity through a case study of pollen grains produced by angiosperms in Barro Colorado Island, Panama (BCI ...

Não existe flor hermafrodita: uma investigação das nomenclaturas utilizadas para as estruturas reprodutivas na alternância de gerações de Angiospermas

open access: yesCiência & Educação, 2022
Resumo A atribuição de nomenclaturas sexuais a plantas ou estruturas da fase esporofítica das angiospermas, como no termo flor hermafrodita, é recorrente no Ensino de Botânica e pode gerar distorções conceituais.
