Estructura morfo-anatómica y salida de dormición física de las semillas de Malvastrum coromandelianum ssp. coromandelianum (Malvaceae)

Boletín de la Sociedad Argentina de Botánica, 2019
Introducción y objetivos: Uno de los principales problemas para el manejo y uso de muchas especies vegetales es la presencia de semillas con dormición física. En este trabajo estudiamos la presencia de dormición física en mericarpos (unidad de dispersión)

Functional traits explain both seedling and adult plant spatial patterns in gypsum annual species

Functional Ecology, Volume 37, Issue 5, Page 1170-1180, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological processes such as seed dispersal or plant–plant interactions and environmental constraints such as climate or soil heterogeneity are known to influence establishment, and thus the spatial patterns of plant communities and populations.

Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

Journal of Ecology, Volume 111, Issue 2, Page 400-411, February 2023., 2023
The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts

Flower strips and remnant semi‐natural vegetation have different impacts on pollination and productivity of sunflower crops

Journal of Applied Ecology, Volume 59, Issue 9, Page 2386-2397, September 2022., 2022
The implementation of flower strips or maintenance of remnant semi‐natural habitats adjacent to sunflower fields showed context‐dependent effects on pollinator visitation rates and crop yield. In highly simplified agroecosystems, these interventions may be insufficient or may need longer times to produce significant effects.

Forest loss and treeless matrices cause the functional impoverishment of sapling communities in old‐growth forest patches across tropical regions

Journal of Applied Ecology, Volume 59, Issue 7, Page 1897-1910, July 2022., 2022
In agreement with the LMFTS hypothesis, our results confirm that landscape modifications in regions undergoing high and long‐lasting deforestation greatly impoverish the functional composition and diversity of sapling communities. The shift from communities composed mainly by conservative attributes towards communities with a higher prevalence of ...

Long‐term and year‐to‐year stability and its drivers in a Mediterranean grassland

Journal of Ecology, Volume 110, Issue 5, Page 1174-1188, May 2022., 2022
This 14‐year study of a species‐rich semi‐natural Mediterranean grassland shows that stability increases with richness, asynchrony and conservative strategies. Fertilization decreases stability by promoting long‐term trends in species composition, favouring competitive species and decreasing richness.

Pollination by bats enhances both quality and yield of a major cash crop in Mexico

Journal of Applied Ecology, Volume 57, Issue 3, Page 450-459, March 2020., 2020
Our study shows that bats provide a vital ecosystem service by pollinating a crop of major socio‐economic importance, and that consideration of both crop quality and yield are essential to fully understanding the benefits of bat pollination. A reduction of this service would result in a decrease in both the size and quality of the harvest, causing ...
