Precipitation timing and soil substrate drive phenology and fitness of Arabidopsis thaliana in a Mediterranean environment

open access: yesFunctional Ecology, Volume 37, Issue 9, Page 2471-2487, September 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract In Mediterranean climates, the timing of seasonal rains determines germination, flowering phenology and fitness. As climate change alters seasonal precipitation patterns, it is important to ask how these changes will affect the phenology and fitness of plant populations.

Linaria sagrensis (Plantaginaceae), a new high mountain species from the SE Iberian Peninsula

open access: yesNordic Journal of Botany, Volume 2023, Issue 9, September 2023., 2023
Linaria sagrensis, from the south‐eastern Iberian Peninsula, is here newly described, illustrated, and compared with its morphologically closest relatives from L. sect. Supinae: L. pruinosa, L. nevadensis, L. glacialis and L. alpina subsp. alpina. The species is characterized by being perennial, entirely glandular‐hairy, with inflorescence dense and ...

Seasonality in niche occupation revealed through bird community functional structure in the southern Atlantic rainforest

open access: yesIbis, Volume 165, Issue 3, Page 986-997, July 2023., 2023
Seasonal variation in tropical and subtropical systems can have different effects on bird species depending on the resources they use and how they use them. However, despite recent research advances, knowledge of the drivers of the presence and abundance of species in different seasons is still limited for most tropical bird species.

Trait evolution during a rapid global weed invasion despite little genetic differentiation

open access: yesEvolutionary Applications, Volume 16, Issue 5, Page 997-1011, May 2023., 2023
Abstract Invasive species often possess a great capacity to adapt to novel environments in the form of spatial trait variation, as a result of varying selection regimes, genetic drift, or plasticity. We explored the geographic differentiation in several phenotypic traits related to plant growth, reproduction, and defense in the highly invasive ...

Digitizing the coral reef: Machine learning of underwater spectral images enables dense taxonomic mapping of benthic habitats

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 596-613, February 2023., 2023
Abstract Coral reefs are the most biodiverse marine ecosystems, and host a wide range of taxonomic diversity in a complex spatial community structure. Existing coral reef survey methods struggle to accurately capture the taxonomic detail within the complex spatial structure of benthic communities.

Management zone‐based estimation of positive and negative nitrous oxide flux in organic corn fields

open access: yesSoil Science Society of America Journal, Volume 86, Issue 4, Page 1043-1057, July/August 2022., 2022
Abstract Accurate estimation of field‐scale nitrous oxide (N2O) fluxes is hindered by their considerable variability and the fact that soils can be both sources and sinks for N2O. This is particularly challenging for organic systems that have complex rotations and inputs.

Directional changes over time in the species composition of tropical vascular epiphyte assemblages

open access: yesJournal of Ecology, Volume 110, Issue 3, Page 553-568, March 2022., 2022
Directionality in the temporal changes of epiphyte assemblages suggests that niche‐based mechanisms dominate these temporal changes. Host size over host identity is the most important environmental filter for epiphyte assemblages establishment. Tree Vectors Pack by Pixeden.com (https://www.freevector.com/trees‐illustrations). Abstract Understanding the

Efeito do tipo de sedimento na eficiência alimentar, crescimento e sobrevivência de Litopenaeus vannamei (Boone, 1931) - doi: 10.4025/actascibiolsci.v33i4.6134

open access: yesActa Scientiarum: Biological Sciences, 2011
Este estudo avaliou o desempenho zootécnico do camarão marinho Litopenaeus vannamei em diferentes tipos de substratos não consolidados. Juvenis (0,97 ± 0,27 g) foram aclimatados na densidade de 52 m-2, em 21 caixas de polietileno com biofiltros ...

Caracterização física de substratos para plantas [PDF]

open access: yesBragantia, 2014
A caracterização física de substratos para plantas no Brasil ainda é incipiente, embora, apenas com a definição adequada de métodos confiáveis seja possível padronizar insumos e fornecer as recomendações necessárias aos produtores. Objetivou-se caracterizar fisicamente seis substratos para plantas e comparar métodos prescritos pelo Ministério da ...
