An annotated and illustrated checklist of hermit crabs (Anomura, Paguroidea) in the Canary Islands: a review of historical records and updated ecological data
No full textHermit crabs from the Canary Islands have historically been documented through broader inventories or isolated records from research surveys. However, no comprehensive review has evaluated these historical records or updated the ecological information on this group. This study presents an annotated and illustrated checklist of hermit crabs in the Canary Islands, compiling and evaluating historical records and incorporating new information from recent studies, including unpublished data from surveys conducted in the archipelago. The present inventory includes 34 species, allowing for additions and deletions of species from previous compilations, confirmation of the presence of species previously considered probable, and an update of the published bibliography on the group in the region. Additional information on the ecology and bathymetric range is provided and updated according to the most recent knowledge, extending the known depth range for several species in the archipelago, particularly poorly known deep-water ones. The study also classifies each species into biogeographic patterns and provides common names in English and Canary Islands Spanish to popularize the species as a preliminary step towards their knowledge and conservation.160,762,6Q1Q1SCIE11,
Impact of tire particle leachates on microplancton communities in the Canary Islands
No full textTire wear particles (TWP) are a major source of microplastics in the environment. Despite their prevalence, the effects of tire particle leachates on marine microplankton communities remains poorly understood. In this study, we assessed the acute impacts of tire particle leachates on the structure of coastal microplankton assemblages from the Canary Islands. Five laboratory experiments were conducted, exposing microplankton to a range of leachate dilutions over 72 h, with TWP leachates prepared from an initial concentration of 1 g L⁻¹ .Our results revealed that the abundances of diatoms, most dinoflagellates, and ciliates were significantly reduced following exposure to leachates, with median effective concentrations (EC50) ranging from 30 to 660 mg L−1 depending on the plankton community. Interestingly, Ostreopsis cf. ovata, a harmful algal bloom (HAB)-forming species, exhibited relatively high tolerance to tire particle leachates compared to other microplankton. Compared to other marine biota, ciliates appear to be most vulnerable plankton group to tire particle leachates (EC50 = 30 and 146 mg L−1). The higher tolerance of O. cf. ovata to pollution compared to other phytoplankton species (resource competitors), in combination with other factors, may contribute to the rise of HABs in polluted coastal areas. Although field data on TWP are limited, the observed negative effects on microplankton occurred at environmentally relevant concentrations. Our results indicate that TWP pollution can significantly impact marine planktonic communities, highlighting the urgent need to reduce TWP emissions and develop less toxic tire rubber additives.121,4186,2Q1Q1SCIE11,
