Trait evolution during a rapid global weed invasion despite little genetic differentiation. [PDF]
Evol Appl, 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 ...

IMPEDÂNCIA MECÂNICA EM SUBSTRATOS HORTÍCOLAS [PDF]
Pesquisa Agropecuária Brasileira, 1999 O poder de penetração das raízes no solo tem sido estudado com vistas a cultivos agrícolas, porém não há dados no que se refere a substratos em recipientes. Neste trabalho avalia-se a impedância mecânica de: areia, perlita, turfa, fibra-de-coco e misturas do mercado internacional: Fafard nº 2, Fafard 2P, Jiffy 7 e Oasis.

Functional 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
Nordic 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 ...

Ibis, 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.

People and Nature, Volume 5, Issue 3, Page 938-949, June 2023., 2023 Abstract Incorporating archaeology within the ecosystem services (ES) framework can offer decision‐makers lessons from the past and a broader sustainability perspective. Given the claimed archaeology‐ES link, the island of Sardinia (Italy) offers an unparalleled opportunity where a unique archaeological heritage occurs in an area of high biodiversity ...

Methods 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
Soil 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
Journal 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

A new species of Emilia (Asteraceae, Senecioneae) from Lower Juba region, Somalia
Nordic Journal of Botany, Volume 39, Issue 6, June 2021., 2021 Emilia corallina is described as a new species endemic to the coastal area of southern Somalia close to the Kenyan border. It is closely related to E. bellioides, the only other species of the genus given for the Flora of Somalia. This narrow endemic grows in coastal dunes and madreporic limestone outcrops along the lower Juba coast and is reported at ...
