Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing. [PDF]

open access: yesAnim Genet
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Effect of Rapid Maxillary Expansion on the Pterygoid Process and Spheno-Occipital Synchondrosis in Skulls With Class II and Class III Skeletal Relationships: A Finite Element Analysis Study. [PDF]

open access: yesInt J Dent
Objetive To evaluate the effect of the rapid maxillary expansion (RME) on the pterygoid process (PP), spheno‐occipital synchondrosis (SOS), and sella turcica (ST) in two patients’ skulls with Class II and Class III skeletal relationships and to identify differences in mechanical loading through finite element analysis (FEA).

Fitness consequences and ancestry loss in the Apennine brown bear after a simulated genetic rescue intervention

open access: yesConservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Reduction in population size, with its predicted effects on population fitness, is the most alarming anthropogenic impact on endangered species. By introducing compatible individuals, genetic rescue (GR) is a promising but debated approach for reducing the genetic load unmasked by inbreeding and for restoring the fitness of declining ...

Cultural importance, availability and conservation status of Spanish wild medicinal plants: Implications for sustainability

open access: yesPeople and Nature, Volume 5, Issue 5, Page 1512-1525, October 2023., 2023
Abstract The harvest of wild plants with medicinal uses is increasing globally, both for self‐treatment and as a source of income. The increasing demand for these remedies could lead to the over‐harvest of some species. Despite a recent surge in the number of studies analysing wild medicinal plants management, little is known about the effects of non ...

Dynamic Adaptive Environmental Flows (DAE‐Flows) to Reconcile Long‐Term Ecosystem Demands With Hydropower Objectives

open access: yesWater Resources Research, Volume 59, Issue 7, July 2023., 2023
Abstract This study investigates how environmental flows (e‐flows) can be designed as dynamic operating policies to optimize long‐term economic and ecosystem performance in reservoir systems. The main goal is to provide e‐flow solutions that contribute to better preparedness and flexibility of hydro‐systems to face multiyear stress periods, reducing ...

Species, taxonomic, and functional group diversities of terrestrial mammals at risk under climate change and land‐use/cover change scenarios in Mexico

open access: yesGlobal Change Biology, Volume 28, Issue 23, Page 6992-7008, December 2022., 2022
We combined trait‐based and correlative approaches to assign risks to species, taxonomic orders, and functional groups of terrestrial mammals in Mexico, under climate change (CC) and land‐use/cover change (LUCC) scenarios. Risk scores were obtained as a function of vulnerability, exposure, and hazard, using the latest Intergovernmental Panel on Climate

Meta‐analysis of landowner participation in voluntary incentive programs for provision of forest ecosystem services

open access: yesConservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract Many voluntary incentive programs for provision of forest ecosystem services (ES) have low participation rates, insufficient enrollment areas, and inefficient ecological outcomes. Understanding participation behavior in such programs has therefore become a crucial part of policy success.

Who gets what, where, and how much? Composite index of spatial inequality for small areas in Tehran

open access: yesRegional Science Policy &Practice, Volume 13, Issue 1, Page 191-205, February 2021., 2021
Abstract Urban spatial inequality is multidimensional and complex. The extant literature identifies three main theoretically‐informed dimensions of spatial inequality—accessibility, environmental conditions, and socio‐economic conditions. We combine geospatial data on measures across these three theoretical dimensions to derive a composite index for ...
