Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves. [PDF]

Conserv Biol
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

The interplay between virus infection and water-related stress is mediated by the plant metabolism of ascorbic acid. [PDF]

New Phytol
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection

Urban Tree Growth and Drought Responses Show Evidence of Climate Resilience. [PDF]

Glob Chang Biol
Urban trees face increasing risks from climate change, including drought and heatwaves, which threaten their growth and survival. By studying 10 tree species across seven Australian cities, we found that local climate strongly influences tree growth, and that some species are well adapted to urban climates.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth. [PDF]

New Phytol
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

Integrating data to assess occupancy patterns of an endangered bumble bee. [PDF]

Conserv Biol
Abstract There is growing interest in integrating community science data with structured monitoring data to estimate changes in distribution patterns of imperiled species, including pollinators. However, significant challenges remain in determining how unstructured community science data should be incorporated into formal analyses of species ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]

New Phytol
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

El futuro de los cítricos: Impacto del cambio climático en la citricultura

Mètode Science Studies Journal: Annual Review, 2022
La citricultura actual está amenazada por el cambio climático. El incremento de las temperaturas, junto a la aparición de otros fenómenos climáticos adversos, modifica las condiciones ambientales de las regiones donde se han desarrollado las variedades ...

Ciencia y política contra la desertificación: La respuesta de las instituciones ante un reto global

Mètode Science Studies Journal: Annual Review, 2023
La desertificación es un concepto controvertido del que aún se discute su naturaleza, extensión, causas y posibles soluciones. En este artículo se revisan los argumentos esgrimidos para situar la desertificación como un gran reto ambiental global y se ...
