Governance and equity in community-based forest carbon projects of SouthEastern Mexico

Voluntary forest carbon markets are global policy instruments in which power asymmetries among actors operating across multiple scales can impose unequal burdens on local communities. This study examines the development of community-based forest carbon projects in southeastern Me...

Reproductive traits, sex‐specific reproductive investment and gonadal dynamics in a spawning surgeonfish

Abstract The razor surgeonfish Prionurus laticlavius is a key herbivore in Eastern Pacific reef communities. This study provides a sex‐specific assessment of its reproductive traits, size at maturity and energetic dynamics in the Gulf of California by integrating biometric indica...

Psammoecus delicatus Grouvelle 1908

based on its type material and a revised key to identify species in the genus are also provided. A phylogenetic analysis based upon four genes (COI, 16S, 18S, 28S) confirms its position within Hesionini.

Optimization of Antimicrobial Concentrations in an Agar-Free, Low-Cost, Wheat Germ-Based Diet for Mass Rearing of Drosophila suzukii

The bottleneck for the mass production of Trichopria drosophilae Perkins (Hymenoptera: Diapriidae), the principal parasitoid of the Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is the lack of efficient mass-rearing methods. Here, we optimized the concentrations of fiv...

Soil environmental background values of potentially toxic elements in Topsoil’s from Karst environments; the case of Peninsula of Yucatan Mexico

Abstract Accurate assessment of soil contamination by potentially toxic elements requires knowledge of local background values; only in this way can false positives or negatives be avoided. The objective of this study was to define environmental background concentrations of poten...

Mitogenomic and phylogenomic analyses identify a cohesive Western Atlantic lineage within the Narcine complex (Torpediniformes: Narcinidae)

Accurate species delimitation within electric rays of the genus Narcine has been hindered by overlapping morphological characters and limited molecular resolution in previous single-locus studies. This study aims to evaluate phylogenetic relationships and species boundaries withi...

Deep seeding resistance in maize: selected after domestication or a strategy of its wild ancestors to escape underground animal burrowing?

Abstract Buried seeds avoid predation ensuring their survival until conditions are suitable for germination. The ability of seedlings to emerge from the soil depends on soil characteristics, burial depth, and the skotomorphogenic program of each species. This process is of intere...

Sustainable Management of Air-Conditioning Systems Condensate Water Recovery

The global water crisis represents one of humanity’s most pressing challenges, with over 2 billion people lacking access to safely managed drinking water. This study presents the implementation and evaluation of an innovative air-conditioning condensate recovery system at Buildin...

Analysis of the Prices and Opportunity Costs of Carbon Capture Projects in Mangroves Compared to Those in Other Productive Systems

Mangroves are highly productive ecosystems due to their great capacity to store carbon, but they are also vulnerable to human activities and adverse environmental conditions. Their conservation is often constrained by the opportunity costs of shifting from traditional economic ac...

Mapping Neighborhood Spatial Structure in Traditional Home Gardens Using UAV-Derived 3D Canopy Models

Understanding the spatial structure of tree communities is fundamental for evaluating ecological interactions and management dynamics in agroforestry systems. However, the structural complexity and small spatial scale of traditional agroecosystems often limit the use of conventio...

Techno-Spatial and Economic Assessment of Rooftop Versus Land-Based Photovoltaic Deployment in a Biodiversity-Sensitive Region of the Mexican Caribbean

Solar photovoltaic (PV) expansion in fast-growing tropical regions requires engineering-based frameworks that compare deployment pathways in terms of electricity generation, spatial footprint, and economic performance. This study develops a techno-spatial and economic assessment...
