Abstract Background: Climate change is creating newly habitable environments in European cities for mosquitoes of the Aedes and Culex genera, known vectors of arboviruses such as dengue and West Nile. Urban infrastructure interventions can be effective adaptation measures for future-proofing cities, although empirical evidence of their effectiveness is scarce. The Agència de Salut Pública de Barcelona (ASPB) is structurally modifying urban storm drains in 2023 in Barcelona, Spain, to prevent the accumulation of stagnant water necessary for Aedes and Culex mosquito reproduction. Methods: In partnership with ASPB, we are conducting the IDEAS randomised controlled trial (RCT) in Barcelona to investigate the effects of mosquito-proofing storm drains on the abundance of adult Aedes albopictus and Culex pipiens mosquitoes encompassing and in the vicinity of drains. Using a parallel-arm design, we have randomised 44 drains to receive mosquito-proofing modification (intervention) or not (control). The primary outcome is the combined counts of total adult Ae.albopictus and Cx.pipiens mosquitoes captured using an entomological aspirator. Secondary outcomes include the presence and total counts of mosquito larvae in water samples. We are measuring these outcomes weekly at each drain starting on 26 June 2023 until no mosquitos are detected. Results: We will quantify outcomes comparing mosquito-proofed and control drains using generalised linear mixed models. We will also conduct stratified analyses by species, sex, and sensitivity analyses, including environmental and sociodemographic factors. Conclusion: Our trial is motivated by the importance of testing urban infrastructure interventions to inform investments for future-proofing European cities against climate change-driven proliferation of infectious disease vectors. Trial registration: This trial is registered as a trial in Open Science Framework Registry. Registration DOI https://doi.org/10.17605/OSF.IO/JZQAH

Automated detection of the yellow‐legged hornet (Vespa velutina) using an optical sensor with machine learning

Pest Management Science (2022)

Cayetano Herrera M. Williams João Encarnação Núria Roura‐Pascual Bastian Faulhaber

The yellow-legged hornet (Vespa velutina) is native to Southeast Asia and is an invasive alien species of concern in many countries. More effective management of populations of V. velutina could be achieved through more widespread and intensive monitoring in the field, however current methods are labor intensive and costly. To address this issue, we have assessed the performance of an optical sensor combined with a machine learning model to classify V. velutina and native wasps/hornets and bees. Our aim is to use the results of the present work as a step towards the development of a monitoring solution for V. velutina in the field.We recorded a total 935 flights from three bee species: Apis mellifera, Bombus terrestris and Osmia bicornis; and four wasp/hornet species: Polistes dominula, Vespula germanica, Vespa crabro and V. velutina. The machine learning model achieved an average accuracy for species classification of 80.1 ± 13.9% and 74.5 ± 7.0% for V. velutina. V. crabro had the highest level of misclassification, confused mainly with V. velutina and P. dominula. These results were obtained using a 14-value peak and valley feature derived from the wingbeat power spectral density.This study demonstrates that the wingbeat recordings from a flying insect sensor can be used with machine learning methods to differentiate V. velutina from six other Hymenoptera species in the laboratory and this knowledge could be used to help develop a tool for use in integrated invasive alien species management programs. © 2022 The Authors.

The invasive Atlantic blue crab Callinectes sapidus Rathbun, 1896 expands its distributional range southward to Atlantic African shores: first records along the Atlantic coast of Morocco

BioInvasions Records (2022)

Abdellatif Chaouti Zahira Belattmania Amal Nadri Ester Á. Serrão João Encarnação

The occurrence of the exotic Atlantic blue crab Callinectes sapidus Rathbun, 1896 (Crustacea: Decapoda: Portunidae) is reported for the first time from the Moroccan Atlantic coast.Working with local fishermen, we gathered 160 records of the Atlantic blue crab from several estuarine, coastal and marine areas, in the period between June and August 2021.These new records confirm its establishment in the Atlantic coasts of North Africa, suggesting a southern range expansion.These findings, likely exacerbated by growing populations along the Atlantic coast of Morocco and temperate coastal waters, provide new insights into the invasion dynamics of this species in the northeast Atlantic Ocean.

Aliens From an Underwater World

Frontiers for Young Minds (2021)

Pedro Morais João Encarnação Maria Alexandra Teodósio Ester Dias

About 3.1 billion people around the world live within 100 km of the coastline. If you are one of those people, then you also live near an estuary. What you probably do not know is that many alien species live in this underwater world, and we are not talking about extraterrestrial species from outer space. Are you scared? Well, do not be! These alien species are from planet Earth. In this article, we will tell you what alien species are, why scientists study them, how any species may become an alien, and how a few alien species may become an invasive species. You will also learn how you can help scientists find and track alien species, and how to defeat them. Along the way, we will give examples of alien species living in the San Francisco Estuary in North America, a paradise for hundreds of alien species.

Free Pass Through the Pillars of Hercules? Genetic and Historical Insights Into the Recent Expansion of the Atlantic Blue Crab Callinectes sapidus to the West and the East of the Strait of Gibraltar

Frontiers in Marine Science (2022)

Enrique González‐Ortegón Selina Berger João Encarnação Hicham Chairi Pedro Morais

The invasive Atlantic blue crab Callinectes sapidus has considerably extended its distribution along the Gulf of Cadiz and Moroccan coasts in the northeast Atlantic. This could indicate a new introduction event in the Gulf of Cadiz from the native area, in case of detectable genetic differences from the Mediterranean Sea populations. To test this and reconstruct the invasion, we assessed the genetic structure of crabs in the Gulf of Cadiz and Alboran Sea. We used sequences of the mitochondrial gene cytochrome c oxidase subunit I (COI), in almost its full length (1511 basepairs), of 149 individuals from three sites along the Spanish Mediterranean coast, two in the Alboran Sea, and two in the Gulf of Cadiz. Our data reveal low genetic variability, with only two haplotypes (here referred to as CSWM1 and CSWM2), compared to its known high genetic diversity in the native range, indicating a strong founder effect in the study region. Here we document an inversion of haplotype predominance between regions, haplotype CSWM2 being dominant in most of the Spanish Mediterranean coast, but less frequent in the Gulf of Cadiz and Alboran Sea. This suggests a secondary introduction of propagules into the investigated area, rather than a new introduction from the native area, nor a natural westward expansion with environmental selection of one haplotype over the other. Further studies with additional populations would help to better unveil the history of yet another invasive species in the Gulf of Cadiz.

Effects of mosquito-proofing storm drains on adult and larvae mosquito abundance: protocol of the IDAlErt storm drAin randomiSed controlled trial (IDEAS)

MethodsX (2024)

Marina Treskova Tomás Montalvo Joacim Rocklöv Charles Hatfield Frederic Bartumeus

Aedes and Culex mosquitoes, known for spreading arboviruses like dengue and West Nile, thrive in cities, posing health risks to urban populations. Climate change can create suitable climatic conditions for these vectors to spread further in Europe. Cities contain numerous landscape and infrastructure elements, such as storm drains, that allow stagnant water build-up facilitating mosquito breeding. Modifying urban infrastructure to prevent water accumulation can reduce mosquito populations, but evidence is limited. The Public Health Agency of Barcelona, Spain, introduced a structural modification of storm drains to prevent water accumulation. Together with the Agency, we designed a randomised controlled trial (RCT) to experimentally assess the effectiveness of these modifications on adult Aedes albopictus and Culex pipiens populations. It is a parallel-arm RCT with equal randomization of 44 drains to receive mosquito-proofing modifications (intervention) or not (control). Primary outcomes are adult mosquito counts and secondary outcomes are larvae and mosquito presence, assessed weekly at each drain until no mosquitoes are detected. Data analyses include generalised linear mixed models to estimate the time-averaged and highest intervention effects, subgroup and sensitivity analyses. The trial results will guide a city-wide expansion of the storm drain modifications and provide valuable evidence to enhance existing vector control measures.

The arrival of a non-indigenous ecosystem engineer to a heavily invaded and flow-regulated estuary in Europe

BioInvasions Records (2024)

João Encarnação Maria Alexandra Teodósio Pedro Morais

Ecosystem engineering bivalves can shape aquatic ecosystems because their high filtration capacity changes water quality and their shells increase the fractal dimension of benthic ecosystems with consequent abiotic and biotic effects.The Asian date mussel Arcuatula senhousia (W.H. Benson, 1842), native to East Asia between the South China Sea and Siberia, is one such bivalve that, despite its small size, can reshape a benthic ecosystem when forming dense, continuous mats.We describe here the first detected population of this non-indigenous species in southern Portugal.The Asian date mussel was found in the middle portion of the Guadiana estuary in 2022.There, river flow has been highly regulated since the construction of the biggest European reservoir in 2002, which may have been the precursor for the establishment of numerous non-indigenous species.We also discuss if this new non-indigenous species indicates an ongoing invasion meltdown process or if it can be framed under the empty niche or niche replacement hypothesis.So far, there is only circumstantial evidence supporting the niche theory hypotheses, but the interaction of several hypotheses promoting the spread and establishment of this species is also likely.Moving forward, better-informed management and conservation efforts should rely on new empirical and experimental evidence to understand the establishment mechanisms of nonindigenous species in the Guadiana estuary.
