The bioinvasion of lionfish Pterois volitans (Linnaeus, 1758) in Brazilian waters: An urgent necessity to create strategies to contain the expansion of the species in Brazil

Research Square (Research Square), Journal Year: 2022, Volume and Issue: unknown

Abstract The lionfish Pterois volitans (Linnaeus, 1758) is considered the most well-established fish species in non-native regions around world, causing severe environmental damage and risks for food chain. In Brazil, was reported first time 2014 State of Rio de Janeiro, currently, P. observed more seven States, being its high level occurrence Northern region, which contains an immense biodiversity that has not been totally cataloged yet. Based on that, this study aims to ratify occupation permanent residence Great Amazon Reef System (GARS), alert urgent need developing control strategies invasive Brazil. new specimens were collected Amapá, between 2021 2022, during commercial lobster fishing, using method “Caçoeira”, covering 70 100 meters depth, while snapper with manzuá, 78 102 depth. laboratory, individuals measured total length (TL) weight (TW). We analyzed 21 from GARS, TL ranged 21,5 35,6 cm average 29,43 cm, TW 150,0 733,0 g, 413,8 g. These adult reinforce stabilization lionfish, have probably completed reproductive cycles requiring action by agencies invasion becoming a future impact native biodiversity.

Benthic macrohabitat classification and Madracis spp. coral patch distribution in a deep-sea marine protected area of Colombia

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: Nov. 15, 2022

Corales de Profundidad National Natural Park (CPNNP), at the central Colombian Caribbean margin, has an extension of 142.195 ha with depths ranging from 34 to 1,234 m. The CPNNP’s essential ecological value is Madracis spp. as potential structure-forming deep-water coral; this work represents first footages these unique habitats for Caribbean. In 11 sectors, remote video surveys are conducted, based on a detailed digital elevation model. From four cover mesophotic zones (46–169m depth), and seven aphotic (up 354m depth). After still images’ description interpretation, guide was generated nine types macrohabitats surrounding coral formations CPNNP: soft substrate (mud/sand), substrate/rubble/rock solitary corals, shell rubble, rock/ledges attached fauna, rugged stones hard sandstone burrows, pockmark fauna. Video transect analysis confirms occurrence spp., patches main framework builder CPNNP. These comprise many clumped 50 80 cm high colonies that developed over slow slopes, seafloor elevations between 107 233 m textured soils not very compact ridges, associated macrohabitat This information being used management monitoring protected area.

Fauna diversity in Madracis spp. coral patches in the Colombian Caribbean

Arxius de Miscel·lània Zoològica, Journal Year: 2023, Volume and Issue: unknown, P. 105 - 128

Published: Oct. 17, 2023

Madracis spp. coral patches are the main deep–sea framework builder observed on shelf–break scarp of Colombian Caribbean, between 107 and 230 m depth. The Marine Protected Area, Corales de Profundidad National Natural Park, was established in 2013 to protect a site high biodiversity associated with communities. Our research summarizes advances knowledge its as result four expeditions offers insights into state fauna. colonies occur five areas park but corals thrive build only two five, both southwest area. surveys have resulted inventory 337 species. Mollusca (116) dominated fauna, followed by Bryozoa (70), Cnidaria (50), Echinodermata (39), Arthropoda (14), Annelida (13), Brachiopoda (3), Chordata (32 fishes).

Géneros de foraminíferos bentónicos en zonas mesofóticas superior y media del Parque Nacional Natural Corales de Profundidad y su potencial como bioindicadores de hábitats y cambios ambientales

Intropica, Journal Year: 2022, Volume and Issue: unknown, P. 262 - 276

Published: Dec. 31, 2022

Los arrecifes coralinos mesofóticos hacen parte del objeto de conservación Parque Nacional Natural Corales Profundidad (PNNCPR). Un paso fundamental para el manejo un área protegida es la caracterización su riqueza específica, y uno los grupos taxonómicos importantes en ambientes arrecifales son foraminíferos bentónicos. Debido a que no existen investigaciones este tipo PNNCPR, se consideró estudiar géneros bentónicos las zonas mesofótica superior media, explorar una posible relación dicha composición con sus ámbitos geográficos batimétricos, así como cambios ambientales. resultados permitieron concluir submuestra 50 individuos conchillas buen estado, tomadas diez muestras 10 g, fue suficiente estimar presentes zona. La encontrada 53, siendo Amphistegina, Quinqueloculina Triloculina presentaron mayor frecuencia aparición. No encontraron diferencias significativas entre conjunto estratos profundidad (34-60 m) medio (61-90 m). El sector Bajo Calamarí difiere significativamente encontrado localidad Frijol. análisis similaridad mediante clasificación ordenación permitió identificar tres congruentes sitio muestreo, época año recolecta. grupo heterótrofos (Quinqueloculina, Triloculina, Cibicides, Discorbis, Rosalina, Poroeponides Textularia) más frecuente, seguido por simbiontes (Amphistegina) oportunistas (Elphidium). obtenidos permiten sugerir tienen potencial ser bioindicadores programa monitoreo PNNCPR.
