Bioenergetic trophic trade-offs determine mass-dependent extinction thresholds across the Cenozoic. [PDF]

open access: yesEcology
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging

From transporter to motor: Evolutionary and structural insights into the emergence of prestin's area-motor activity in mammals. [PDF]

open access: yesProtein Sci
Abstract Prestin, a member of the SLC26A family, is essential for the electromotility of mammalian outer hair cells, converting voltage changes into mechanical work. In contrast, nonmammalian orthologues function as anion transporters. To investigate the molecular and structural basis of this functional divergence, we performed ancestral sequence ...

Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

Migration, Repression and Homosexual Sociability in Francoist Spain: An Analysis of the Case Files of the Special Courts of Barcelona (1965–1975)

open access: yesGender &History, EarlyView.
ABSTRACT In Spain, under General Franco's regime, homosexuality was regarded as an antisocial and dangerous behaviour. It was thus pursued both by the police and judicial courts. The Law on Vagrants and Crooks (1954) and, subsequently, the Law on Dangerousness and Social Rehabilitation (1970) constituted the legal mechanisms used by the dictatorship to
