In this work, we show how it is possible to test the nullity of covariances, in a set of variables, using a simple univariate procedure. The methodology proposed enables us to perform the multivariate test of independence of several variables, under specific conditions for the covariance structure. The methodology proposed may be used in the high‐d...

The world is on an urgent transition to renewable energies. Photovoltaic (PV) solar energy is the most viable green energy source to be produced at the domestic level, allowing every individual to contribute. Understanding the factors that influence the adoption of domestic solar energy, how it changes throughout the country and how spatial depende...

Principal Component Analysis (PCA) is one of the most used multivariate techniques for dimension reduction assuming nowadays a particular relevance due to the increasingly common large datasets. Being mainly used as a descriptive/exploratory tool it does not require any explicit a priori assumption. However, regardless the parent population miss/un...

Environmental impact assessment (EIA) follow-up monitoring in energy projects, such as wind farms, solar facilities and power lines, frequently encompasses bird fatality surveys based on regular carcass searches. Since a large number of bird carcasses are often not found, field experiments to determine carcasses persistence (CP) and searcher effici...

Linear infrastructures, such as power lines and roads, are an important source of bird mortality. However, little is known on the potential effect of these infrastructures on local scavenger guilds, their foraging activity and the resulting bird carcass removal patterns. This is an important source of bias in studies aiming to quantify bird fatalit...

The Manila clam (Ruditapes philippinarum) is one of the most traded bivalves in the world. Knowing its harvesting location is therefore paramount to guarantee the safety of consumers. The present study employs fatty acid (FA) profiles of the adductor muscle (AM) to reveal the most likely harvesting location of four batches of Manila clams suspected...

Developing methodologies employed to trace the geographic origin of seafood as accurate and fast as possible can help to speed-up the delivery of results to legal authorities, reduce associated costs and minimize environmental impacts (associated with the residues generated). The present study evaluated if trace element fingerprints (TEF) of a smal...

Atmospheric CO2 levels have been rising due to an increase in anthropic activities and its implications over marine ecosystems are unprecedented. The present study focused on the effects of ocean acidification (OA) on key hematological parameters of the juvenile small‐spotted catsharks (Scyliorhinus canicula). Eggs were reared throughout the entire...

The diversity and abundance of cleaner species have been frequently associated with ectoparasite load and ecological wealth of tropical fish communities. Cleaning behaviour in temperate regions has received less attention, with few labrid species being described as cleaners. The context and frequency of cleaning behaviour by juvenile white seabream...

The expansion of overhead power lines worldwide challenges companies of energy transmission and distribution, regulators and environmental consultants, among other stakeholders, to effectively mitigate their negative impacts on wildlife. Wire-marking is currently the most widespread and recommended measure to reduce bird collisions with these infra...

Patterns of larval supply and larval condition at metamorphosis play key roles in the structure and dynamics of marine populations. Hence, biological and environmental conditions driving the dispersion of larval individuals, shape early life phenotypes, and influence their survival and post-settlement success. We performed a study over two consecut...

Wastewater effluents are teeming with organisms, nutrients and chemical substances which water treatment processes fail to remove. Among these substances, pharmaceuticals such as antidepressants are a frequent occurrence, and have been reported to lead to severe effects in the physiology and behaviour of non-target marine species across taxa. Venla...

The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling symbiotic features observed in the animal kingdom, i.e., their mollusk-plastid association, whi...

Wind energy production across the globe has grown over the years and Portugal is no exception. Like other forms of energy production, wind energy causes ecological impacts and these impacts are a matter of major concern. One of the impacts caused by operating wind farms is bird and bat casualties due to collision with the wind turbines. Since real...

The impact of the operation of wind farms on birds and bats in terms of true fatality is still unknown. However, fatality numbers can be estimated using statistical methods that have improved over recent years, aiming to provide a closer representation of the real ecological conditions. To assess which statistical methods have been used to estimate...

Small pelagic fishes are known to respond rapidly to changes in ocean climate. In this study, we evaluate the effects of future environmental warming (+2°C) during the early ontogeny of the European sardine, Sardina pilchardus. Warming reduced the survival of 30-day-old larvae by half. Length at hatching increased with temperature as expected, but...

Context To assess the real impact of human-made structures on bird and bat communities, a significant number of carcass-removal trials has been performed worldwide in recent decades. Recently, researchers have started to use camera traps to record carcasses exact removal time and better understand the factors that influence this event. Aims In our...

This study aims to examine the usage of complementary and alternative medicine (CAM) on a sample of Portuguese women with history of breast cancer. A total of 107 women with history of breast cancer attending Movimento Vencer e Viver Lisboa responded to a questionnaire designed to assess the use of CAM, as well as other variables, such as satisfact...

Over the last few years, great efforts have been made to improve the methodologies used to assess bird and bat fatalities at wind farms. For that purpose, several mortality estimators have been proposed. In general, these estimators account for: 1) partial coverage; 2) carcass removal (e.g. by scavengers or decay); and 3) imperfect detection. Perha...

Distance sampling is extensively used for estimating animal density or abundance. Conventional methods assume that location of line or point transects is random with respect to the animal population, yet transects are often placed along linear features such as roads, rivers or shorelines that do not randomly sample the study region, resulting in bi...

In monitoring studies at wind farms, the estimation of bird and bat mortality caused by collision must take into account carcass removal by scavengers or decomposition. In this paper we propose the use of survival analysis techniques to model the time of carcass removal. The proposed method is applied to data collected in ten Portuguese wind farms....

During the last years there has been a significant worldwide increase in the number of wind farms. This kind of energy can have negative impacts, such as the direct mortality or lethal injury of birds and bats caused by collision with wind turbines. In order to evaluate bird (or bat) mortality regarding wind power generation facilities, strict moni...

In this study, the power of common goodness-of-fit (GoF) statistics based on the empirical distribution function (EDF) was simulated for single type-I right-censored data. The statistical power of the Kolmogorov–Smirnov, Cramér–von Mises and Anderson–Darling statistics was investigated by varying the null and the alternative distributions, the samp...

Mathematical tasks provide the context in which students learn mathematics. Although many factors also determine the learning process, instructional tasks operate as the “proximal causes” of students’ learning from teaching. Their characterization can therefore help to understand the link between teaching and learning mathematics. Different mathema...

Ammonia is a very important air pollutant, playing an widespread role in acid pollution chemistry. The knowledge of the deposition processes (wet and dry) is of extreme importance for both long-range transport modelling and evaluation of critical loads for specific ecosystems.
