Peasant Movements and the Fourth Transformation in Mexico: What Does the Theory of Collective Empowerment Tell Us?

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT This article examines peasant and Indigenous movements in Mexico since Morena's rise to power in 2018 through the lens of collective empowerment theory, a theory of political‐cultural formation. Beyond offering an empirical assessment, the theory is refined and formalized through an analysis of these movements and their relationship to ...

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

open access: yesMedical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.

Effects of essential amino acids on phagostimulation and reproduction in adults of the Mediterranean fruit fly Efectos de amino ácidos esenciales en la fago‐estimulación y reproducción en adultos de la mosca de las frutas del Mediterráneo

open access: yesPhysiological Entomology, EarlyView.
The phagostimulation and reproductive effects of individual essential amino acids, without other nutrient except fructose, were investigated. Methionine, Arginine and Leucine display significantly higher phagostimulation strength than fructose. Arginine and Methionine showed a significant improvement in reproductive activity compared to other tested ...

Decomponology: A board game for understanding soil carbon dynamics

open access: yesNatural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Soils sustain life and regulate global carbon cycling, yet the processes governing soil organic matter dynamics are inherently complex, involving multiple pathways and positive and negative feedbacks. Traditional concepts such as humus often portrayed soil carbon as a static pool whose persistence was attributed largely to the inherent ...

Impacto del uso del suelo sobre la condición de ribera en arroyos pampeanos y su relación con la estructura de la comunidad de peces

open access: yesBiología Acuática, 2019
In the last 30 years agricultural areas have occupied a larger proportion of cultivable zone in the Pampa Plain, generating the movement of livestock activities to the margins of waterways. These changes in land use can cause hydrological, morphological,

Does the Adoption of Improved Cassava Varieties Boost Productivity in Ghana? The Role of Technology, Management, and Structural Gaps

open access: yesWorld Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT Agricultural development initiatives in sub‐Saharan Africa have emphasized improved crop varieties as a pathway to food security, resilience, and rural poverty reduction. However, empirical evidence often focuses narrowly on plot‐level outcomes and overlooks whole‐farm effects and the substantial heterogeneity in farmers' management practices,

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

open access: yesGlia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.

Performance of homozygosity by descent in two mice lines divergently selected for birth weight environmental variability

open access: yesScientific Reports
Inbreeding can have negative effects, such as increasing the expression of deleterious alleles or reducing fitness. A method based on Hidden Markov Models (HMM) was developed to determine the probability of an individual genome in a homozygous-by-descent
