Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

Ecological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

The FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

Violencia de género, migración y estructuras familiares

Revista Internacional de Investigación y Transferencia en Comunicación y Ciencias Sociales
La violencia de género, la migración y las transformaciones en las estructuras familiares son fenómenos interconectados que recrudecen la vulnerabilidad de las mujeres. Esa forma de agresión, profundamente arraigada en sistemas patriarcales, afecta especialmente al colectivo migrante, que se enfrenta a riesgos como la trata de personas, la explotación ...

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

Ibis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...
