Are integrative systematic tools efficient toward unraveling species diversity with the genus Jania (Corallinaceae, Rhodophyta)?

open access: yesJournal of Phycology, EarlyView.
Abstract The articulated genus Jania currently comprises 54 accepted species, making it the fourth most speciose genus among corallines, following Lithophyllum, Amphiroa, and Lithothamnion. Unlike these other genera, Jania is relatively easy to identify at a generic rank. However, morpho‐anatomical characters are insufficiently discriminant for species

Epitypification of Merismopedia tranquilla (Cyanobacteria) prompts phylogenetic reassessment of the genus and the description of two morphologically similar genera

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Merismopedia is morphologically characterized by its distinctive colony arrangement yet exhibits considerable variability among species. Recent studies suggested that Merismopedia is polyphyletic, and its most likely true lineage was provisionally placed within the Microcystaceae. However, the available molecular data for most of the

Pollination services mapping and economic valuation from insect communities: a case study in the Azores (Terceira Island)

open access: yesNature Conservation, 2017
Insect pollinators provide vital ecosystem services through its maintenance of plant biological diversity and its role in food production. Indeed, adequate pollination services can increase the production and quality of fruit and vegetable crops.

First record of the Mediterranean asteroid Sclerasterias richardi (Perrier in Milne-Edwards 1882) in the Azores Archipelago (NE Atlantic Ocean) [PDF]

open access: yes, 2018
The first occurrence of the Mediterranean fissiparous asteroid Sclerasterias richardi (Perrier in Milne-Edwards 1882) is reported from the Azores based upon dredged material off the south coast of São Miguel Island at 135 m depth.

On the Noncommutativity Approach to Supersymmetry on the Lattice [PDF]

open access: yes, 2006
The noncommutativity approach to SUSY on the lattice is shown to be inconsistent and a similar inconsistency is displayed for the link approach.Comment: 3 pages; talk presented by FB at "Quark Confinement and the Hadron Spectrum VII", September 2-7 ...

Claiming the Isle? Islandness and Territorial Demands

open access: yesNations and Nationalism, EarlyView.
ABSTRACT This article explores the relationship between insularity and territorial demands, focusing on whether island territories are more likely to support regionalist and secessionist parties. To address this question, we compare electoral support for such parties across island and mainland territories using a large‐N dataset.

Surface Roughness and Fractal Analysis of TiO2 Thin Films by DC Sputtering

open access: yesEngineering Proceedings
This study examines the effect of oxygen concentration and sputtering power on the surface morphology of TiO2 thin films deposited by DC reactive magnetron sputtering. Surface roughness parameters were obtained using MountainsMap® software(10.2) from SEM

Forecasting Climate Change Using a Multivariate Cointegrated System

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

A Field-Driven Growth Model for Uniform Thin-Film Growth

open access: yesMicromachines
Externally applied electric fields are widely employed during thin-film deposition to improve film uniformity, texture and densification. Despite extensive experimental evidence, the physical mechanisms by which such fields influence nucleation, surface ...
