The success of non-native species (NNS) invasions depends on patterns of dispersal and connectivity, which underpin genetic diversity, population establishment and growth. In the marine environment, both global environmental change and increasing anthropogenic activity can alter hydrodynamic patterns, leading to significant inter-annual variability...

Inland recreational fishing is primarily considered a leisure-driven activity in freshwaters, yet its harvest can contribute to food systems. Here we estimate that the harvest from inland recreational fishing equates to just over one-tenth of all reported inland fisheries catch globally. The estimated total consumptive use value of inland recreatio...

The long-term provision of ocean ecosystem services de- pends on healthy ecosystems and effective sustainable man- agement. Understanding public opinion about marine and coastal ecosystems is important to guide decision-making and inform specific actions. However, available data on pub- lic perceptions on the interlinked effects of climate change,...

Recreational fishing with the principal motivation of leisure is associated with important economic, social and conservation values. Nonetheless, it is also a primary pathway for the introduction and spread of invasive non‐native species and aquatic animal disease. Several studies have explored the overall biosecurity risk posed by recreational ang...

Non-native species are spreading at an unprecedented rate over large spatial scales, with global environmental change and growth in commerce providing novel opportunities for range expansion. Assessing the pattern and rate of spread is key to the development of strategies for safeguarding against future invasions and efficiently managing existing o...

The long-distance transfer of non-native, potentially invasive species via floating marine debris is an increasing threat to biodiversity and conservation efforts. To address the lack of understanding around mechanisms and pathways of species transfer via marine debris, a novel modelling approach was applied to recreate the likely trajectory and so...

Inland recreational fisheries, found in lakes, rivers, and other landlocked waters, are important to livelihoods, nutrition, leisure, and other societal ecosystem services worldwide. Although recreationally-caught fish are frequently harvested and consumed by fishers, their contribution to food and nutrition has not been adequately quantified due t...

Jellyfish bloom events in the Northeast Atlantic (NEA) are perceived to be increasing, based on a rise in reports of their interactions with human activities, including coastal recreation. However, few studies have assessed the potential impact of bloom events on coastal recreation in the NEA. This article reports findings of a questionnaire carrie...

Southeast Asia is considered to have some of the highest levels of marine plastic pollution in the world. It is therefore vitally important to increase our understanding of the impacts and risks of plastic pollution to marine ecosystems and the essential services they provide to support the development of mitigation measures in the region. An inter...

Open water swimming is becoming an increasingly popular recreational activity. Understanding the human well-being benefits that open water swimmers derive from interaction with outdoor spaces is fundamental to environmental decision making, yet little is currently known about the benefits, threats and needs of open water swimmers in relation to the...

The freshwater and marine ornamental fish industry is a primary route of hazard introduction and emergence, including aquatic animal diseases and non‐native species. Prevention measures are key to reducing the risk of hazard incursion and establishment, but there is currently little understanding of the biosecurity practices and hazard responses im...

Invasive Non-Native Species (INNS) can co-transport externally and internally other organisms including viruses, bacteria and other eukaryotes (including metazoan parasites), collectively referred to as the symbiome. These symbiotic organisms include pathogens, a small minority of which are subject to surveillance and regulatory control, but most o...

Plasticity in growth and life-history traits is an important attribute of non-native (NN) fishes, facilitating their adaptation to novel environments. Few studies have investigated geographical variations in multiple biological traits and the factors affecting the variations. In this study, variations in multiple biological traits of NN sailfin cat...

Marine non-indigenous species are a significant threat to marine ecosystems with prevention of introduction and early detection considered to be the only effective management strategy. Knowledge of the unaided pathway has received relatively little attention, despite being integral to the implementation of robust monitoring and surveillance. Here,...

Lake Léman (Lake Geneva), Switzerland, is known to have undergone major environmental change over the last few decades, including changes in the abundance, distribution, and species composition of macrophytic plants (aquatic plants). In this study, questionnaires and key informant interviews were used to assess lake users’ perceptions of broad scal...

The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, stakeholders and management decisions on global threats to aquatic ecosystems, 195 assessors representing 120 risk assessment area...

Aquatic invasions are a major ecological and socioeconomic concern. Management of invasive aquatic populations requires a robust understanding of the effectiveness and suitability of control methods. In this review, we consider multiple control options for the management of invasive aquatic amphipods, exploring their efficacy and application constr...

There is increasing focus on the frequency of jellyfish blooms in the Northeast Atlantic because of negative interactions with humans. However, uncertainty exists as to whether perceptions of increasing bloom frequencies reflect reality due to limitations within long-term population trend data. This study, therefore, developed and applied a semi-qu...

Invasive non‐native species (NNS) are internationally recognised as posing a serious threat to global biodiversity, economies and human health. The identification of invasive NNS already established, those that may arrive in the future, their vectors and pathways of introduction and spread, and hotspots of invasion are important for a targeted appr...

Evolutionary‐based measures of biodiversity play an increasingly important role in theoretical conservation biology, complementing more traditional methods such as patterns of species richness and endemicity. To date, very few studies have used evolutionary data to assess patterns of biodiversity in the Afrotropical region, particularly for freshwa...

The European Non-native Species in Aquaculture Risk Analysis Scheme (ENSARS) was used to assess one of the most popular aquaculture species in the world, the striped catfish Pangasianodon hypophthalmus (Sauvage), in two locations of southern Anatolia (Turkey). The overall mean risk score generated for P. hypophthalmus by the ENSARS Organism module...

Increasingly, molecular approaches are uncovering biodiversity that was previously unrecognized by traditional morphological taxonomy. Cryptic or pseudo-cryptic species are commonly documented in freshwater environments, where isolation of dispersal-limited taxa in fragmented hydrological networks often results in high intraspecific gen- etic diver...

The complete mitogenome of Palaemon capensis is presented here. The mitogenome is 15,925 bp in length and comprises 13 protein coding genes, 2 ribosomal subunit genes, 22 transfer RNAs, and a non-coding AT-rich region. The PCGs were used to perform a phylogenetic analysis together with other Caridea representatives with mitogenome data from GenBank...

Phenotype–environment associations in coloration often involve camouflage, enabling organisms to blend into their environment and thereby reducing predatory attacks. The nature of any associations may vary among receivers with different visual systems and at different spatial scales, but these effects have rarely been investigated together. We stud...

Recent studies in southern Africa have revealed a wealth of novel freshwater crab species in high mountainous regions. In the present study, phylogeographic affinities between two sister mountain-living freshwater crab species (Potamonautes brincki and P. parvicorpus) were examined for novel lineages. Seventy-six crab specimens were collected throu...

The structural morphology of the first pereiopod (P1) in crangonoid shrimps is investigated here for the first time using scanning electron microscopy, with particular emphasis on morphological variation in the distal margin (PDM) of the occluding margin of the propodus. Results indicate that there is a high level of morphological variation in the...

Camouflage is widespread throughout the natural world and conceals animals from predators in a vast range of habitats. Because successful camouflage usually involves matching aspects of the background environment, species and populations should evolve appearances tuned to their local habitat, termed phenotype-environment associations. However, alth...

Camouflage is perhaps the most widespread anti-predator defense in nature, with many different types thought to exist. Of these, resembling the general color and pattern of the background (background matching) is likely to be the most common. Background matching can be achieved by adaptation of individual appearance to different habitats or substra...

Tegumental scales are documented in two families of Caridea, viz. Hippolytidae (genus Lysmata) and Rhynchocinetidae (genera Cinetorhynchus and Rhynchocinetes), raising to seven the number of families in which such scales occur. The scales in Rhynchocinetidae are similar to those in Pandalidae, but the scales in Lysmata spp. are of a slightly differ...
