Bordering Marine Belonging: The Meanings, Mobilities and Materialities of Bioinvasion

Опубликована: Янв. 1, 2025

Abstract This chapter focuses on the relationship between borders and belonging in marine worlds, paying special attention to debates concerning invasive species. Within a number of natural social science disciplines, studies species are both long-established continuing grow change. Major research into ‘invasions’ has come later than terrestrial studies, so critical scholarship (or bioinvasion) remain largely (though not exclusively) landlocked. Where watery, they fresh, rather salt water ‘interior’ focusing ‘exterior’ liquid zones. two aims. It firstly identifies as topical issue that is marginal discussions ocean bordering/belonging. secondly puts forwards three ways which bioinvasion, bordering can be better understood, through (1) questions definition meaning; (2) an mobilities materialities enrolled within processes bioinvasion—the movement global circuits; (3) how enacted view via biosecurity measures. The aims disrupt conventional narratives belonging, showing biological world ‘stitched’ together.

Contrasting Patterns of Genetic Variability in Pet‐Traded Red Swamp Crayfish Procambarus clarkii and Its Feral Populations

ABSTRACT The ornamental pet trade has emerged as one of the most important pathways for introduction non‐native aquatic species. In last two decades, freshwater crayfish have become a popular group, with numerous populations established through this way, including some North American red swamp Procambarus clarkii (Girard, 1852). Whilst routes aquaculture‐derived been identified molecular methods and historical documents, obtaining traceability in market is often more challenging. We analysed 283 pet‐traded feral P. individuals, originating from Europe Southeast Asia, variation fragment mitochondrial gene cytochrome c oxidase subunit I (COI) to determine genetic amongst 11 shops various countries, outdoor aquaculture Indonesia 27 likely releases animals. found 13 haplotypes, four which had not detected before.

Riverine Barrier Removals Could Proliferate Biological Invasions

Global Change Biology, Год журнала: 2025, Номер 31(3)

Опубликована: Март 1, 2025

Multiple stressors, such as pollution, climate change, invasive species and fragmentation, threaten global ecosystems, requiring holistic management actions. Freshwater ecosystems are disproportionately biodiverse particularly impacted by fragmentation biological invasions. Artificial barriers, dams weirs, long-standing features of landscapes, with a divergence views on their benefits disbenefits. Recognition the negative impacts barriers river continuum native biota, for migratory aquatic species, has led to rapid rate barrier removals in recent decades, especially North America Europe. However, since rise riverine construction centuries ago, invasion rates have concurrently surged. can paradoxically slow spread through freshwaters, removal efforts thus risk proliferating that disperse rapidly connected habitats. Despite well-intended plans restoration removals, subsequent colonisation been largely overlooked. This presents 'connectivity conundrum': intuitively addresses issues migrations dispersals, but could perversely exacerbate species.

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

Functional Ecology, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter frugivores' foraging decisions, temporal dynamics of might influence interaction outcomes. However, community phenological patterns that determine trait availability can be altered by invasive non‐native fleshy‐fruited species (‘INNFS’), potentially disrupting native plant–animal interactions. We aim to relative contributions plants INNFS ripe variability terms abundance morphological, nutritional functional traits. Additionally, we test whether are morphologically nutritionally redundant fruiting phenology supplements variation throughout year. surveyed 22 sites a subtropical Andean forest north‐western Argentina combined this with available data on morphological for 52 five INNFS. Multidimensional spaces were constructed diversity metrics calculated traits, weighted species' abundances. Data was grouped time period (start rainy season, end season dry season) groups compared abundance, (functional) turnover, differences plant complete (i.e., including INNFS) explored.

Analysing factors underlying the reporting of established non-native species

Abstract A nexus of natural and human variables mediate the success non-native species that threaten global biodiversity ecological stability. However, relative importance interplays among relevant factors has not been holistically approached. To identify spatial differences potential connections in drivers, we analyzed number established European countries using a newly collated database species. We employ series broadscale national predictors classified into ‘research’, ‘economy’, ‘environment & culture’, ‘land-use’ to predict successful establishment. Our null models, which assume distribution mirrors each predictor, accurately predicted numbers across countries. few were identified as outliers, having significantly over- or underrepresented based on adjusted quasi-Poisson quantiles. network analysis compositions these regions be central hubs (e.g. Germany, France, Switzerland), but also highlighted distinct similarities Combinations culture’ explained largest shares well their reporting rates over time. Individual drivers alone insufficient wholly explain differences, whereas interacting driver categories ultimately accounted for variance. This demonstrates breadth establishment, particularly highlights relevance overlooked historical-cultural facets affecting biological invasions.

Human-induced pressures have led to substantial changes in marine ecosystems worldwide, with the introduction of non-indigenous species (NIS) emerging as a significant threat ecological, economic, and social aspects. The Macaronesian islands, comprising Azores, Madeira, Canary Islands, Cabo Verde archipelagos, are regions where regional economy is dependent on resources (e.g., traffic, ecotourism fisheries).

Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in ecosystems they occupy. Understanding global distribution of these animals is often hindered due to paucity distributional data. Additionally, non-native introductions becoming more frequent, which can cause severe environmental economic impacts. Management decisions related their habitats require accurate, up-to-date data mapping tools. Such currently patchily distributed with limited accessibility rarely up-to-date.

The Role of Non‐Native Plant Species in Modulating Riverbank Erosion: A Systematic Review

River Research and Applications, Год журнала: 2025, Номер unknown

Опубликована: Янв. 21, 2025

ABSTRACT Riverbank erosion is a naturally occurring process that influences riparian zone habitats. However, anthropogenic activities are increasing rates of riverbank erosion. Climate change and hydrological physical modifications drive perturbations. Whilst native vegetation can reduce erosion, the proliferation non‐native plant species has been linked to instability, with marked changes in fluvial erosional regimes attributed invasion by such as Impatiens glandulifera (Himalayan Balsam) or Tamarix (Tamarisk) into zones. Yet, role modulating remains unclear, part due lack investigations quantify geomorphic change. We systematically assessed relevant ecological geomorphological literature determine current understanding offer recommendations for future research on plant—riverbank Included articles focused limited number across restricted range habitats types, dependency topographic generally short study duration obscuring potential causal links feedback cycles.
