Environmental heterogeneity and spatial variation mediates plant diversity and ecosystem stability in mountain ecosystems of the Mediterranean Andes

Ecography, EarlyView.
Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Phenotypic disparity in Iberian short-horned grasshoppers (Acrididae): the role of ecology and phylogeny

BMC Evolutionary Biology, 2017
Background The combination of model-based comparative techniques, disparity analyses and ecomorphological correlations constitutes a powerful method to gain insight into the evolutionary mechanisms that shape morphological variation and speciation ...

Immigrant reproductive dysfunction facilitates ecological speciation.

Evolution; international journal of organic evolution, 2017
The distributions of species are not only determined by where they can survive - they must also be able to reproduce. Although immigrant inviability is a well-established concept, the fact that immigrants also need to be able to effectively reproduce in foreign environments has not been fully appreciated in the study of adaptive divergence and ...

Membrane Engineering for Battery Systems: Bridging Design Principles and Frontier Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The review emphasizes membrane separators' role in battery performance and safety, covering redox flow, lithium‐ion, and solid‐state batteries. It reviews advances in membrane materials (e.g., polymer electrolytes, hybrid composites) and ion transport mechanisms, while addressing challenges like dendrite growth and crossover losses.

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Speciation happens in company – not in isolation

npj Biodiversity
Oceanic islands are considered the classic arenas for allopatric speciation and adaptive radiation. Established concepts of speciation and endemism are strongly focused on spatial and temporal scales.

You stay, but I Hop: Host shifting near and far co‐dominated the evolution of Enchenopa treehoppers

Ecology and Evolution, 2018
The importance and prevalence of phylogenetic tracking between hosts and dependent organisms caused by co‐evolution and shifting between closely related host species have been debated for decades.

Interactions Between O‐Phospho‐L‐Serine and Trivalent Metal Ions: Studies in Solution and Solid State

European Journal of Inorganic Chemistry, EarlyView.
The interaction between the phosphorylated amino acid O‐phospho‐L‐serine and trivalent ions of f‐elements such as La3+, Eu3+, and Lu3+, supplemented by Y3+, has been studied in aqueous media. Nuclear magnetic resonance (NMR) spectroscopy in solution and in the solid state examined complex formation from the ligand perspective, while time‐resolved laser‐

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Patterns of gene flow define species of thermophilic Archaea.

PLoS Biology, 2012
Despite a growing appreciation of their vast diversity in nature, mechanisms of speciation are poorly understood in Bacteria and Archaea. Here we use high-throughput genome sequencing to identify ongoing speciation in the thermoacidophilic Archaeon ...
