Bivalve shells can potentially alter the structure of aquatic benthic communities. However, little is known about the effect that different shell morphologies have on their associated fauna. This study aimed to understand how empty shells, from four different freshwater bivalve species, affect macrozoobenthic communities, using the River Minho (Ibe...
The effects of tourist visitation and food provisioning on fish assemblages were assessed by visual censuses (stationary technique) carried out in a tropical reef in Northeastern Brazil. Comparisons of species abundance, richness, equitability, and trophic structure in the presence (PT) and absence (AT) of tourists suggest that tourist visitation a...

Background
The paper presents an extensive fish sampling dataset spanning a long-term period from 2010 to 2019. The data were collected in Lenta Marina, an upstream area in the Minho Estuary of the NW Iberian Peninsula, which belongs to a LTSER (Long-Term Socio-Ecological Research) platform. To capture fish, fyke nets were utilised as the sampling...
As the effects of climate change continue to intensify, non-native species are becoming more prevalent in estuarine ecosystems. This has implications for the taxonomic and functional diversity of fish communities. Historically, biodiversity has been a synonym of taxonomic diversity, however this approach often fails to provide accurate insights on...

Floating wetland islands (FWI) are nature-based solutions that can be applied in different water bodies, such lakes, ponds and rivers, considering a wide range of purposes. They have been considered for eutrophication abatement, wastewater treatment and ecosystem rehabilitation. They are of great value since their efficiency relies on bioremediatio...
The Asian clam Corbicula fluminea has been widely introduced into aquatic ecosystems and may impact the physiological condition and survival of native freshwater mussels. However, very few studies have evaluated this issue quantitatively. To fill this gap, manipulative field experiments were performed to assess two possible mechanisms of impact on...
Despite the increasing awareness of climate change, few studies have used the Intergovernmental Panel on Climate Change (IPCC) scenarios to simulate the effects of climate change on estuarine populations of crustaceans. The objective of this study was to investigate the effects of temperature and salinity fluctuations on the population dynamics of...
Extreme weather events are becoming more frequent as a result of climate change, and the increasing frequency of these events may lead to significant changes in fish assemblages. In this sense, this work aimed to study the effects of climate change and extreme weather events on fish assemblages in the Rio Minho estuary (Portugal). Between 2010 and...

Knowledge on population dynamics of ecosystem's key-species is invaluable to understand how populations will respond to natural and human-induced perturbations. The amphipod Echinogammarus marinus is a key-species from European estuarine habitats with a distribution ranging from Norway to Portugal [1]. The present article contains supportive data r...
Corbicula fluminea is a known aquatic invasive species responsible for several ecological and economic impacts. In Portugal, it is found in all major watersheds, although to varying degrees of invasion (regarding density, biomass and spatial distribution). The aim of this study was to evaluate the spatio-temporal differences in condition indices (C...
Inter-population variability may arise as a response to adverse natural and anthropogenic stressors. The dynamics of a key amphipod species (Echinogammarus marinus) was followed during ≈ 1-year at its southerly range (NW Portugal), in three estuaries with different levels of anthropogenic pressure (High - Ave estuary; Moderate - Mondego estuary; Lo...
• Freshwater mussels (Order Unionida) are highly threatened. Interspecific competition for food sources with invasive alien species is considered to be one of the factors responsible for their decline because successful invaders are expected to have wider trophic niches and more flexible feeding strategies than their native counterparts.
• In this...
Intraspecific agonistic interactions are widespread across the animal kingdom, with
many individual morphological and physiological characteristics playing important
roles in the fate of disputes. Additionally, changes to environmental conditions can
influence the outcomes of animal contests. The shore crab (Carcinus maenas) is a
globally distribut...
Bivalve shells can persist over a geological time, acting as important physical resources to the associated fauna. However, few studies have investigated their relevance as persistent long-term ecological attributes to the ecosystem. As such, it is relevant to investigate the shell decays in riverine systems subjected to different environmental con...
Freshwater mussels (Bivalvia, Unionida) are one of the most imperilled faunal groups globally, being the introduction of invasive species a possible major mechanism of threat. The Asian clam Corbicula fluminea is a problematic invasive species in aquatic ecosystems and can impair the survival of parasitic larvae (glochidia) of native freshwater mus...
An ecosystem model of the Minho estuary (NW coast of Iberian Peninsula) was implemented in AQUATOX 3.1 (US-EPA) to check whether the effects of temperature rise, dry years, rainy years and river flow decrease acting isolated (single stressor) or combined (multiple stressor) would induce the same type of response on macroinvertebrate biomass variati...
A population dynamics model was developed to assess the short and long-term effects of temperature and salinity variations in the common goby Pomatoschistus microps in a Portuguese estuary (Minho estuary, NW Portugal). The population was divided into juveniles, females and males, which constituted the model's state variables. Linear regressions bet...
Biotic interactions such as predation may
influence the success of invasive alien species (IAS).
Although the Asian clam Corbicula fluminea is recognized
as one of the most problematic aquatic IAS, few
studies have investigated its use as a food resource. In
this study, we aimed to investigate (i) the palatability of
C. fluminea under natural (Minh...
Co-extinctions are increasingly recognized as one of the major processes leading to the global biodiversity crisis, but there is still limited scientific evidence on the magnitude of potential impacts and causal mechanisms responsible for the decline of affiliate (dependent) species. Freshwater mussels (Bivalvia, Unionida), one of the most threaten...
Marine protected areas (MPA) are important tools for the evaluation of the biodiversity and status of marine systems. However not all MPAs are equal in their design and management, therefore it is important to understand how different levels of protection affect the fish communities. In this study, the shallow reef fishes of seven areas in Fernando...
is well recognized for its in-vasive behavior and ecological impacts. • We tested the effects of C. fluminea on an microbial community. • The presence of living C. fluminea stimulated fungal biomass and bacterial diversity. • Bioturbation by C. fluminea is the potential main mechanism explaining our results. The Asian clam Corbicula fluminea (Mülle...
Resource pulses are episodes of low frequency, large magnitude and short duration that result in increased resource availability in space and time, with consequences for food web dynamics. Studies assessing the importance of resource pulses by invasive alien species in the interface between terrestrial and aquatic ecosystems are rare, especially th...
Co-extinctions have received trivial consideration in discussions about the global conservation crisis, even though recent studies have emphasised their importance. This situation is even more pronounced in freshwater ecosystems where this phenomenon is largely unrecognized. In this presentation we explore the role of fish for freshwater mussels’ c...
The Asian clam Corbicula fluminea (Müller, 1774) has been recognized as one of the most important invasive alien species in aquatic ecosystems and may have significant ecological and economic impacts. Recently, the presence of C. fluminea was associated with changes in benthic and epibenthic fauna. In this study, we aimed to understand the mechanis...
Background/Question/Methods
The Asian clam Corbicula fluminea is one of the most invasive species in aquatic ecosystems. Given the usual high density and large spatial distribution, this species can significantly alter ecosystem structure and functioning through several mechanisms, including ecosystem engineering. In this study, the engineering e...
This study aimed at comparing the feeding, territorial and agonistic behavior of the Rocas Gregory Stegastes rocasensis when guarding egg clutches. This was accomplished through underwater observations of 80 S. rocasensis individuals observed in four sampling sites in the Fernando de Noronha archipelago (SW Atlantic). Several differences were detec...
Reef fish usually display a remarkable variety of colours and coloration patterns. The colour patterns are largely used for species identification, and some morphologically conservative genera are highly dependent on coloration for this purpose. In this context, this paper aims to briefly describe unusual colour patterns recorded for territorial da...
This paper presents the results of the first field study of the Brazilian endemic damselfish Stegastes rocasensis. Underwater data were collected at the Fernando de Noronha Archipelago (NE Brazil), where four sites were visually assayed for local territorial and feeding behaviors, as well as habitat use. S. ocasensis preferentially fed on turf and...
Extirpation or even extinction of freshwater invertebrate species is a neglected conservation issue; declines in abundance and spatial distribution for freshwater invertebrates are far less documented than for vertebrate species. In the Minho River tidal freshwater wetlands (northwest of Iberian Peninsula), a rapid decline in density and biomass of...
Habitat use and the processes which determine fish distribution were evaluated at the reef flat and reef crest zones of a tropical, algal-dominated reef. Our comparisons indicated significant differences in the majority of the evaluated environmental characteristics between zones. Also, significant differences in the abundances of twelve, from thir...
Spatial distribution, microhabitat use and territorial and feeding behaviours were compared between the juveniles of two sympatric territorial damselfishes Stegastes variabilis and Stegastes fuscus on a small tropical reef in the southwestern Atlantic Ocean. Juvenile S. variabilis were most abundant at sites subject to stronger hydrodynamics and wi...
Shallow reefs on the coast of Paraíba state are poorly known. An analysis at three stations (Prot = protected; SP = semi-protected; Exp = exposed) with different gradients of wave exposure revealed significant (p < 0.05) differences related to the biomass of seaweed (Prot = SP ≠ Exp). Station Exp with 9.97g (23%) presented the lowest value followed...
Shallow reefs on the northeastern coast of Brazil are rich, productive and diverse environments, with great ecological and economical importance. Picaozinho is located 1,500 m off the coast of Joao Pessoa city, Paraiba state, NE Brazil. The aim of this work is to provide an updated list of the reef fishes of Picaozinho, based on a survey of approxi...
Uncontrolled recreational activities are known to cause severe damage to reef dwelling organisms and to the reef overall structure. In order to investigate the effects of human recreational activities on the reef fish assemblage, surveys were undertaken in two shallow coastal reefs (Picãozinho and Quebra Quilhas) with similar physiographic features...
Associations of the hairy blenny Labrisomus nuchipinnis (Labrisomidae) are described for the first time from different observations made on the coast of Brazil, South Atlantic. The first involved a majid crab cleaning the fish and the second, another fish following closely a foraging hermit crab of the genus Paguristes (Diogenidae).
