Breaking the norm: Absence of seed size/seed number trade‐off in Hymanaea stigonocarpa, a tree species from the Brazilian semi‐arid

Plant Species Biology, Volume 40, Issue 5, Page 472-482, September 2025.
Seed size/number trade‐off is a central topic in plant biology as it reflects ecological and evolutionary aspects of the species. Here we report the absence of a trade‐off mass/number of seeds and fruits in a polyspermic plant probably associated to abortion of self‐pollinated pistils and flowers.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

¿CÓMO UNA ESPECIE EXÓTICA SE CONVIERTE EN INVASORA?

Tecnociencia, 2010
Se analizan los posibles mecanismos que permiten a una especie exótica convertirse  en invasora: aumento de la variación genética, disminución de los enemigos  naturales, regulación biótica, purga, mutaciones adaptativas, cambios epigenéticos.

Topofilia, paisaje y sostenibilidad del territorio

Enrahonar: Quaderns de Filosofia, 2014
En este trabajo, realizamos un análisis de las funciones evolutivas que tiene el amor al territorio y al paisaje (topofilia). Estas funciones son, básicamente, dos: fijar la población al territorio y establecer relaciones de solidaridad con las ...

Vineyard maturity increases arbuscular mycorrhizal and decreases plant pathogen fungal relative abundance in bulk soil across a 1,000 km Chilean gradient

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 987-997, July 2025.
Wine production has a significant impact on the global economy. Despite this, the microbial composition of the terroir has not been studied sufficiently, particularly in the southern hemisphere. Here, we investigated how bulk soil fungal communities are affected by several abiotic and biotic factors across 1,000 km of Chilean vineyards.

Influências de fatores abióticos no desenvolvimento da cultura da erva-mate

Agropecuária Catarinense, 2021
A erva-mate, que era tradicionalmente obtida a partir de ervais nativos, vem nos últimos anos sendo cultivada em povoamentos puros. Esta prática tem acarretado o aumento de pragas e doenças.

Terroir and rootstock effects on leaf shape in California Central Valley vineyards

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 1110-1122, July 2025.
The innumerable effects of terroir—including climate, soil, microbial environment, biotic interactions, and cultivation practice—collectively alter plant performance and production. A more direct agricultural intervention is grafting, in which genetically distinct shoot and root genotypes are surgically combined to create a chimera that alters shoot ...

Young maize plants impact the bacterial community in Australian cotton‐sown vertisol more than agricultural practices

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
In an irrigated Vertisol, different cotton farming systems affected only a few bacterial groups and potential metabolic functions. However, the application of maize plants or their neutral detergent fibre fraction had a significant impact on many of them. Abstract Changes in soil characteristics due to varying farming practices can modify the structure
