Tourism Labor Market and the Attainment of the 2030 Agenda for Sustainable Development Goals: Pending Challenges, Ongoing Opportunities and More Responsible and Inclusive Scientific Research for the Advancement of the Tourism Industry

open access: yesSustainable Development, Volume 34, Issue 3, Page 4400-4433, June 2026.
ABSTRACT Concerning human resources, research in the tourism sector has traditionally focused on a personnel‐managerial perspective rather than a labor market‐condition analysis per se, limiting the examination of its unique working ecosystem and distinct socioeconomic particularities. This has evidenced an apparent thematic research gap in the tourism

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 321-333, June 2026.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

Genetic and environmental regulation of arbuscular mycorrhizal responsiveness in petunia: Implications for breeding and trait selection

open access: yesPlant Biology, Volume 28, Issue 4, Page 1145-1158, June 2026.
Arbuscular mycorrhiza responsiveness varies strongly among Petunia species and RILs, representing a genetically determined trait with breeding potential that is nonetheless strongly modulated by environmental conditions. Abstract Arbuscular mycorrhizal (AM) fungi enhance plant nutrition and stress tolerance, yet their agricultural use remains limited ...

Naturally Caffeinated Functional Beverage Based on Grape Juice and Cryoconcentrated Yerba Mate Extract

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT This study investigates the impact of cryoconcentration as a nonthermal enrichment strategy on the chemical, antioxidant, mineral, and sensory properties of mixed beverages composed of grape juice (SU) and yerba mate extract. Aqueous yerba mate extract was subjected to two successive cryoconcentration stages, and the enriched fraction (EMC1.5)
