Adaptive Reproductive Strategies of Limpets in a Harvest‐Influenced Environment

Fisheries Oceanography, EarlyView.
ABSTRACT Limpet harvesting is a size‐selective activity that primarily removes the largest individuals, leading to reduced reproductive output. This study investigates the fecundity strategies of two limpet species, Patella aspera and Patella crenata, inhabiting the rocky shores of Gran Canaria.

Asteroseismic Stellar Modelling with AIMS [PDF]

, 2017
The goal of AIMS (Asteroseismic Inference on a Massive Scale) is to estimate stellar parameters and credible intervals/error bars in a Bayesian manner from a set of asteroseismic frequency data and so-called classical constraints. To achieve reliable parameter estimates and computational efficiency, it searches through a grid of pre-computed models ...

Global fisheries governance and case study of fisheries governance of Autonomous Region of European Union – Azores [PDF]

, 2014
This article seeks to identify the key principles that should guide the definition of the Global Fisheries Governance and Management. A particular focus for this work has been the concept of participative governance and the co-management systems in which

Abundance and distribution of seamounts in the Azores [PDF]

Marine Ecology Progress Series, 2008
We characterized the seamount distribution of the economic exclusive zone (EEZ) of the Azores (Portugal) using 2 bathymetry datasets. Our algorithm showed that peaks and seamounts are common features in this region of the North Atlantic. The density obtained of 3.3 peaks of all sizes per 1000 km 2 is in the same order of magnitude as that obtained on ...

Species traits may predict extinction risk of Azorean endemic arthropods

Insect Conservation and Diversity, EarlyView.
Ground‐dwelling endemic arthropods face a higher extinction risk due to habitat degradation and invasive plants. Canopy species may seem less threatened but still face extinction risks from habitat fragmentation. Body size and trophic group did not predict species threat levels.

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

Nature 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.

Movements, growth rates and strong sexual segregation in critically endangered tope sharks Galeorhinus galeus in the Northeast Atlantic

Journal of Fish Biology, EarlyView.
Abstract The tope (Galeorhinus galeus, Linnaeus, 1758) is a critically endangered shark, which, like numerous elasmobranchs, faces severe global decline. There are, however, substantial disparities between this species' global conservation status and those of some local populations, with the Northeast Atlantic representing a relative stronghold for ...

Market Potential, Road Accessibility, and Firm Births: Evidence From 20 Years of Road Investment

Journal of Regional Science, EarlyView.
ABSTRACT This paper investigates the causal effects of road accessibility, measured by market potential, on firm births in Portuguese municipalities between 1991 and 2016, a period marked by significant road improvements. We address the endogeneity of market potential by employing instrumental variables within Poisson Pseudo‐maximum Likelihood ...

Variability of antioxidant properties, catechins, caffeine, L-theanine and other amino acids in different plant parts of Azorean Camellia sinensis

Current Research in Food Science, 2020
During Camellia sinensis tea processing, manufacturers usually remove the internodes, which are classified as waste. This study presents the first determination of plant part contribution, particularly internodes, to green tea quality, in order to find ...

Angiotensin I-converting enzyme (ACE) inhibition and biological activities of green and black tea samples from Azorean Camellia sinensis

Journal of Functional Foods, 2023
The inhibition of ACE can be targeted in order to control hypertension and much attention has recently been paid towards the search for natural products as alternatives to synthetic drugs due to their adverse side effects associated with them.
