Key agroecosystems for the conservation of amphibians and reptiles in Europe

open access: yesConservation Biology, EarlyView.
Abstract Agricultural expansion and intensification are driving amphibian and reptile declines worldwide. However, sustainably managed agroecosystems can support a high diversity of herpetofauna, which play a key role in pest control, reducing crop damage.

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

open access: yesConservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

‘Civilizing’ Smallholders Through Oil Palm: The Politics of Subsumption Across Southern Mexico's Commodity Frontiers

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT While most frontier studies associate commodity expansions with dispossession, I argue that such expansions can also function as ‘civilizational’ projects aimed at overcoming traditional farming and creating new rural subjects better suited to the needs of capitalist development. Using a Gramscian approach to study subsumption, I analyse three

Palaces for a New Spain Nobility: Between Creole Identity and Academicism

open access: yesSociology Lens, Volume 38, Issue 1, Page 75-86, March 2025.
ABSTRACT Mexico City and Havana had a significant number of noble palaces during the eighteenth century. Until now, the dearth of historical documentation on their construction has hampered any approximation, requiring other methodologies. Here, it is intended to establish how a new visual code was defined, consistent both with their local style and ...

Evaluating maturity of organic matter in hydrated C1 and CM‐like clasts and a dehydrated clast within a polymict eucrite and a howardite

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Anammox: un tratamiento sustentable para el agua residual de rastros

open access: yesTendencias en energías renovables y sustentabilidad
El tratamiento de aguas residuales generadas en rastros representa un desafío ambiental significativo, debido a su alta carga de nitrógeno y materia orgánica. Tradicionalmente, se han utilizado procesos de nitrificación-desnitrificación para remover el nitrógeno, pero estos implican altos costos energéticos, uso de productos químicos y generación de ...

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, EarlyView.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...
