Moonlighting bacteriophage proteins derepress staphylococcal pathogenicity islands por Tormo-Mas, María A., Mir, Ignacio, Shrestha, Archana, Tallent, Sandra M., Campoy, Susana, Lasa, Inigo, Barbe, Jordi, Novick, Richard P., Christie, Gail E., Penadés, José R.

“…Here we show that SaPI derepression is effected by a specific, non-essential phage protein that binds to Stl, disrupting the Stl-DNA complex and thereby initiating the excision-replication-packaging cycle of the island. …”

Prediction of the soil saturated paste extract salinity from extractable ions, cation exchange capacity, and anion exclusion por Visconti, Fernando, De-Paz, José M.

“…Therefore, best estimates of saturation paste extract properties occurred after taking into account the following: (i) free equilibration of the soil solution with the minerals calcite and gypsum under CO2 partial pressure of the saturated paste; (ii) further equilibration of the soil solution with the exchange complex; and (iii) determination of salt contents within the diffuse double layer (DDL) of the soil colloids, i.e. the anion exclusion. …”

Citrus leafminer 'Phyllocnistis citrella' (Lepidoptera: Gracilariidae) and its parasitoids: Ten years after the implementation of Classical Biological Control in Spain por Karamaouna, F., Pascual-Ruiz, Sara, Urbaneja, Alberto, Jaques, Josep A.

“…Today, fourteen years after the introduction of the pest and the following implementation of a Classical Biological Control Programme comprising the introduction of six exotic parasitoid species (Ageniaspis citricola, Quadrastichus sp., Semielacher petiolatus, Galeopsomyia fausta, Cirrospilus ingenuus and Citrostichus phyllocnistoides) for the control of the pest, the citrus leafminer does not cause damage of economic importance on mature trees whereas a new balance of the parasitoid complex-pest system has established in the area of release. …”

Rehabilitation and renovation of cocoa (Theobroma cacao L.) agroforestry systems. A review por Somarriba, Eduardo, Peguero, Felipe, Orozco-Aguilar, Luis, López-Sampson, Arlene, Leandro-Muñoz, Mariela E, Jagoret, Patrick, Sinclair, Fergus L.

“…Deciding on Rh/Re is often a complex, expensive and conflictive process. In this review, we (1) explore the diversity of contexts, driving forces, stakeholders and recommended management practices involved in Rh/Re initiatives in key cocoa-producing countries; (2) summarise the often conflicting views of farmers and extension agents on Rh/Re programmes; (3) review the evidence of age-related changes in planting density and yield of cocoa, given the weight of these variables in Rh/Re decision processes; (4) describe the best known Rh/Re systems and their most common management practices; (5) propose an agroforestry Re approach that overcomes the limitation of current Rh/Re diagnosis protocols, which do not consider the regular flow of food crop and tree products, and the need to restore site soil quality to sustain another cycle of cultivation of cocoa at the same site; and (6) explore the effects of climate change considerations on Rh/Re decision-making and implementation processes. …”

Making Global Climate Action work for nature and people: Priorities for Race to Zero and Race to Resilience por Boran, Idil, Pettorelli, Nathalie, Köberle, Alexandre C, Imbach Bartol, Pablo Andrés, y otros más

“…Yet, the integration of nature in climate ambition is more complex than indicated in the calls to action. We here identify key areas of concern in the alignment of climate and biodiversity goals, discussing the biophysical and socio-ecological considerations relative to (i) practices for enhancing land-based and marine sinks to limit warming; (ii) the unpredictability of biodiversity dynamics under climate change; (iii) the spatial scale at which actions can be implemented; and (iv) the types of metrics that can be used for tracking progress. …”
