Agricultura familiar, multifuncionalidade da agricultura e ruralidade: interfaces de uma realidade complexa. [PDF]

, 2012
Nas últimas décadas, assistimos à revitalização do debate em torno da agricultura familiar pela incorporação das discussões sobre as múltiplas funções da agricultura num rural que não pode mais ser visto como domínio exclusivo da atividade agrícola e dos

Business Model and Sustainable Development Goals for an Innovative Agricultural Waste Management: Distributed Biogas Production

Sustainable Development, EarlyView.
ABSTRACT Technological progress and population growth have increased global pork demand; leading to a rise of methane emission from pig farming, a key contributor to climate change. Anaerobic digestion offers a sustainable solution by converting manure into biogas.

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits

Economic Anthropology, EarlyView.
ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Disentangling Multitrophic Interactions: How Vegetation Cover, Wild Boar, Deer, and Predators Shape Rodents Activity and Acorn Dispersal

Integrative Zoology, EarlyView.
Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.

Genetic control of wheat flour end-use quality and rheology by genome-wide association studies. [PDF]

Plant Genome
Abstract Improving end‐use quality in bread wheat (Triticum aestivum) requires dissecting the genetic basis of complex processing traits and deploying robust prediction pipelines in breeding. We performed genome‐wide association studies (GWASs) using 1767 high‐quality single‐nucleotide polymorphisms generated by genotyping‐by‐sequencing in a diverse ...
