Key message Quantitative mass spectrometry of Arabidopsis telomerase uncovered AtLa1, a homolog of ciliate and yeast proteins that promotes telomerase maturation. AtLa1 is essential for telomerase function in vivo, and in vitro it engages the same region of AtTR bound by AtNAP57, homologous to a telomerase accessory from mammals. Abstract Striking divergence is evident in the biogenesis pathways and protein complements of telo...

Aim To assess phylogeographic structure, phylogenetic diversity and historical diversification processes in ammotrechid camel spiders from the Baja California Peninsula. Location Baja California Sur, Mexico. Time Period Miocene to Pleistocene. Major Taxa Studied Ammotrechid camel spiders (Solifugae: Ammotrechidae). Methods We conducted the first phylogeographic analysis of Baja California Sur ammotrechid camel spiders using mi...

Streptococcus agalactiae was confirmed as the etiologic agent of streptococcosis in Nile tilapia ( Oreochromis niloticus ) from Campeche, Mexico, during a cross‐sectional investigation of eight semi‐intensive farms (2021–2022) that yielded virulent strains in a challenge assay. Standard bacteriology, histopathology, API‐20 Strep phenotyping, one‐step PCR, and real‐time PCR confirmed S. agalactiae in five farms (62.5%). Gross a...

The future of how we understand and manage ecosystems largely depends on direct and continuous observations that connect local territories to planetary processes. Latin America (LATAM: Mexico, Central and South America, and the Caribbean) hosts ecosystems critical for regulating global carbon, water, and energy cycles. However, persistent underinvestment in science and technology hampers the long‐term monitoring capacity neede...

Aims The olive tree is a major crop in Mediterranean countries, but its cultivation faces growing challenges due to climate change. Nematophagous fungi are considered key components of soil ecosystems and can potentially control plant-parasitic nematode populations. This study aims to explore the diversity of these fungi in Mediterranean olive groves, assess their potential for controlling plant-parasitic nematodes, and identi...

Male crickets transfer sperm via a spermatophore, which also contains compounds that enhance ovulation, egg hatching, and the female's longevity. These compounds also may induce mechanisms to guarantee males’ paternity. In Macroanaxipha macilenta (Saussure, 1897) , there are two male morphs, the Wide-Forewing, and the Narrow-Forewing. During mating, Wide-Forewing males transfer one spermatophore to the female, whereas Narrow-F...

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Thematic Assessment Report on Invasive Alien Species and Their Control presents a “conceptual diagram of management-invasion continuum”, introducing a versatile framework to support decision-making on the management of biological invasions. Drawing on an extensive synthesis of current knowledge, this IPBES invasion-management framework...

Aquaculture is the fastest-growing seafood production system globally, offering economic and social opportunities for small-scale fishing communities. Yet, it is often introduced through top-down, technocratic approaches that ignore the social-ecological realities of these communities. Drawing on four case studies from Mexico and Honduras, this study uses a multistage, participatory mixed-methods approach to examine the integr...

Understanding physiological integration in invasive clonal plants is relevant to invasion biology because resource transfer across ramets may allow alien plants to buffer spatial heterogeneity in their introduced areas. However, experimental evidence across native and non-native ranges is limited. Here, we tested whether physiological integration provides greater performance benefits to Carpobrotus taxa in non-native than nati...

Age-related skeletal muscle deterioration is a commonly reported disability among older adults, attributed to several factors including mitochondrial dysfunction, a major hallmark of aging. Therapies to attenuate or reverse mitochondrial decline are limited. Despite identified positive relationships between vitamin B12 (B12) and mitochondrial biology, the impact of B12 supplementation on skeletal muscle mitochondria, in advanc...

Purpose Systematic collection and analysis of antimicrobial resistance data from key bacterial pathogens is essential to contribute to control antimicrobial resistance (AMR). The aim of this work was to survey the drug resistance on clinically relevant organisms stratified according to age, gender, clinical specimens and facilities. Methods Microbiological data were collected from 55 centers across 24 states in Mexico between...

Fungal endophytes have emerged as a promising strategy for sustainable crop management, due to their remarkable ability to synthesize a wide array of secondary metabolites with beneficial effects on plants. These microorganisms establish asymptomatic relationships within plant tissues and can produce bioactive compounds with biocidal properties. Despite promising advances, the mechanisms of symbiosis remain unclear and there i...
