Haplosyllis is a worldwide distributed genus of marine annelids, commonly associated with other invertebrates. Its characteristic simple bidentate chaetae have often led to mistakes in estimating the real diversity of the genus. Currently, Haplosyllis includes 38 species, nearly half of which inhabit the Indo‐West Pacific (IPW). Nevertheless, this...

Specimens of squat lobsters belonging to the family Galatheidae, representing the genera Galathea and Nanogalathea, were collected during several cruises carried out in New Caledonia, Papua New Guinea, the Philippines and Phoenix Islands. The study of these specimens integrating molecular and morphological data revealed the presence of eight new sp...

The porcelain crab Porcellana africana was originally identified as a subspecies of Porcellana platycheles , a species widely distributed in the eastern Atlantic Ocean and the Mediterranean Sea. A study characterizing the recent invasion of P. africana in South Africa places doubts on the identification and previously reported distribution of popul...

The increase in the use of molecular methodologies in systematics has driven the necessity for a comprehensive understanding of the limitations of different genetic markers. Not every marker is optimal for all species, which has led to multiple approaches in the study of the taxonomy and systematics of polyclad flatworms. The present study evaluate...

Aquatic ecosystems are particularly vulnerable to the introduction of non-indigenous species (NIS), leading to multi-faceted ecological, economic and health impacts worldwide. The Iberian Peninsula comprises an exceptionally biodiverse Mediterranean region with a high number of threatened and endemic aquatic species, most of them strongly impacted...

European crayfish species are a clear example of the drastic decline that freshwater species are experiencing. In particular, the native species of the Iberian Peninsula, the white clawed-crayfish (WCC) Austropotamobius pallipes, is listed as “endangered” by the IUCN and included in Annex II of the EU Habitat Directive and requires especially atten...

Extra-pair paternity (EPP) is the consequence of the interactions between a social pair and extra-pair males during the female's fertile phase in a specific social context and ecological environment. Although EPP occurs in many avian species, there is a lack of understanding of how environmental factors may impact its frequency. Accordingly, the re...

An important goal of LIFE INVASAQUA is to develop tools that will improve management and increase the efficiency of the Early Warning and Rapid Response (EWRR) framework for Invasive Alien Species (IAS) in the Iberian Peninsula. Horizon scanning for high risk IAS is basic when implementing measures to reduce new invasions and to focus efforts on th...

MHC genes play a fundamental role in immune recognition of pathogens and parasites. Therefore, females may increase offspring heterozygosity and genetic diversity by selecting males with genetically compatible or heterozygous MHC. In birds, several studies suggest that MHC genes play a role in mate choice, and recent evidence suggests that olfactio...

The number of epizootics in amphibian populations caused by viruses of the genus Ranavirus is increasing worldwide. Yet, causes for pathogen emergence are poorly understood. Here, we confirmed that the Common midwife toad virus (CMTV) and Frog virus 3 (FV3) are responsible for mass mortalities in Iberia since the late 1980s. Our results illustrate...

Unravelling the evolutionary history of taxa requires solid delimitation of the traits characterising these. This can be challenging especially in groups with a highly complex taxonomy. The squat lobster family Munididae contains more than 450 species distributed among 21 genera, Munida being the most speciose (~300 species). Previous phylogenetic...

The Chilean Patagonia is a complex puzzle of numerous fjords, channels, bays, estuaries, and islands. The largest part of it is very remote, hampering the generation of scientific knowledge and effective management planning that could balance conservation of the marine resources with the increasing development of aquaculture activities. The present...

The freshwater blenny Salaria fluviatilis has a circum-Mediterranean distribution, but it is restricted to highly specific habitats and is particularly susceptible to human disturbances, leading to the decline of Iberian populations of the species, resulting in their classification as Vulnerable. The aim of this study is to evaluate the genetic div...

Context Spatially heterogeneous oceanographic properties such as currents, waves, and biogeochemical gradients control the movement of gametes and larvae of marine species. However, it is poorly understood how such spatial dynamics may shape the genetic connectivity, diversity, and structure of marine populations. Objectives We applied a seascape...

Heterozygosity affects mate selection and can modulate interactions among family members and their fitness-related decisions. We studied whether nestling heterozygosity affected parent–offspring interactions and sib–sib competition in the Blue Tit (Cyanistes caeruleus) while controlling for the degree of relatedness among nestlings. Demanding envir...

Squat lobsters constitute an exceptional group to address evolutionary studies in marine species because of their high diversity at multiple taxonomic levels. The families included within Galatheoidea are characterized by morphological, molecular, and ecological differences. Previous phylogenetic reconstructions have considered either Galatheidae,...

Brazil, home to one of the planet’s last great forests, is currently in trade negotiations with its second largest trading partner, the European Union (EU). We urge the EU to seize this critical opportunity to ensure that Brazil protects human rights and the environment. Brazil’s forests, wetlands, and savannas are crucial to a great diversity of I...

It is known that heterozygosity affects mate selection in various taxa. But also beyond mating, in species with parental care, heterozygosity can modulate interactions among family members and their fitness-related decisions. However, to date, this question remains little explored. Here, we studied whether nestling heterozygosity was related to par...

The taxonomy of Munida Leach, 1820 from the north-eastern Atlantic and Mediterranean Sea was studied using a comparative analysis of morphological characters and molecular markers (mitochondrial and nuclear). Generalized Mixed Yule Coalescence and the Poisson tree process models were used to delimit two groups of closely related species associated...

Genetic connectivity studies are essential to understand species diversity and genetic structure and to assess the role of potential factors affecting connectivity, thus enabling sound management and conservation strategies. Here, we analyzed the patterns of genetic variability in the marine snail Gibbula divaricata from five coastal locations in t...

The genus Leiogalathea Baba, 1969 currently contains only two benthic species both occurring on the continental shelves and slope: L. laevirostris (Balss, 1913), widely reported in the Indo-Pacific region, and L. agassizii (A. Milne Edwards, 1880), from both sides of the Central Atlantic. A certain degree of morphological variability linked to thei...

The genus Coralliogalathea of the family Galatheidae is easily differentiated from other genera in the family by its small size, the presence of three to four small lateral teeth on the rostrum and the lack of the first pair of gonopods in males. The genus currently consists of only a single species, Coralliogalathea humilis, which lives in close a...

Dendropoma petraeum, considered the primary vermetid reef-building species in the Mediterranean, has recently been shown to be a species complex of at least four cryptic species.
