Eenymeenymyzostoma nigrocorallium n. sp. is the first species of myzostomid worm associated with black corals to be described. Endoparasitic specimens E. were found three antipatharians on Great Reef Toliara. Individuals inhabit gastrovascular ducts their hosts and evidence infestation is, most time, not visible externally. Phylogenetic analyses based 18S rDNA, 16S rDNA COI data indicate a close relation cirripedium, only other genus. The morphology very unusual compared that more...
Antipatharians, also known as black corals, represent a small group of anthozoan hexacorallians found in all oceans the world. They are generally considered deep-water taxon; however, some most diverse communities from tropical shallow waters. With few poorly detailed exceptions, shallow-water corals Indian Ocean and especially those Madagascar mostly unknown. In this study, we report for first time highly coral assemblage Western thriving waters upper mesophotic depths (10–52 m depth) along...
Abstract Black corals are important components of mesophotic and deep-water marine habitats. Their presence at great depths (e.g., 50 to 200 m) makes accessibility difficult, limiting our understanding the associated biodiversity. Amphipods dominate vagile epifauna in habitats around world, fulfilling ecosystem functions. However, there no studies on amphipods exclusively with black corals, including relationships between their ecological patterns abundances) size coral colonies. We...
Shallow-water antipatharians host many symbiotic species, which spend their adult life with and/or use them to have access food. Here we determine the trophic relationships between four common macrosymbionts observed on/in Cirripathes anguina, Cirrhipathes densiflora and Stichopathes maldivensis in SW Madagascar. These include myzostomid Eenymeenymyzostoma nigrocorallium, gobiid fish Bryaninops yongei, two palaemonid shrimps, Pontonides unciger Periclimenes sp. The first is an endosymbiont...
Abstract While many bee species are experiencing population declines, some host plant generalist bees remain common in Europe, partly because they seem able to shift new resources. However, foraging on a alternative plant, such as an invasive species, can modify diet quality and have potentially detrimental effect health. Herein, we investigated whether the spread of Impatiens glandulifera affects Bombus pascuorum regarding parasite prevalence, genetic structure, nest density Belgium. no...
Black corals (Cnidaria: Antipatharia) have been used all around the world for a long time, whether as money or medicinal purposes and jewellery manufacturing. Except in Hawaii where these fisheries are well known, black coral harvests usually made without any control management. This is case many tropical islands particularly Madagascar, illegal trade continually expanding. Since 2011, an traffic of has occurring main cities southern coastal regions Ambovombe Tolagnaro. In 2014 2015,...
Black corals are key species of marine ecosystems. They can be found in dense aggregations worldwide, but some parts the world remain totally unexplored. This is case Mesophotic Coral Ecosystem Mo'orea where Under Pole scientific expedition explored mesophotic ecosystems between 60 and 120 m depth focused on whip black corals. A total 64 specimens were analyzed morphologically genetically, all belonged to genus Stichopathes. Among them, we describe new Stichopathes desaturata sp. nov. It...
Abstract We provide the first record of shallow and mesophotic (< 150 m depth) antipatharian coral Antipathes grandis VERRILL, 1928 from Indian Ocean. First described Hawaii, A. was recently found on a reef in SW Madagascar. Its identity confirmed by means morphological molecular analyses (cytochrome c oxidase subunit I). These findings not only expand our knowledge potential geographic range corals, but also challenge belief that deep-sea (> 200 benthic taxa have such wide distributions.
The scleractinian biodiversity of Madagascar is mainly known from one study performed in the Bay Toliara (SW Madagascar) 1970s. In present study, this was re-investigated 40 years later, at 2 sites previously considered as atypical, but now subject to high anthropogenic pressures. Results showed lower species diversity compared previous and similar Indian Ocean region, most well-rep- resented genera were recorded. occurrence unrecorded suggests that communities are changing, addition...
Random sampling of shallow-water black corals colonies Cirrhipathes anguina was carried out over a period 13 months near the Great Reef Toliara in southwest Madagascar. Small pieces tissue were collected monthly from base and apex each colony. A total 114 sets upper lower sections observed. There 37 males 39 females for sex ratio 0.95, which not significantly different 1:1. On female male colonies, 56% 60% polyps, respectively, showing developing gametes no embryo nor larvae. Based on these...
Here, we report a new broad approach to investigating the presence and density of Symbiodiniaceae cells in corals order Antipatharia subclass Hexacorallia, commonly known as black corals. Antipatharians are understudied ecosystem engineers shallow (<30 m depth), mesophotic (30–150 m) deep-sea (>200 reefs. They provide habitat numerous organisms, enhancing supporting coral reef biodiversity globally. Nonetheless, little biological ecological information exists on antipatharians,...
A neotype is designated for the antipatharian coral Antipathes flabellum Pallas, 1766. The was collected off Madagascar (the original type locality given as Oceanus Indicus). Morphologically, corresponds closely in corallum shape and skeletal spination to specimens that have traditionally been identified flabellum. Another specimen of A. from Madagascar, morphologically almost identical described here, has sequenced using ultra conserved elements exon nuclear loci, which showed it falls...
We present the first open-access, island-wide isotopic database (IsoMad) for modern biologically relevant materials collected on Madagascar within past 150 years from both terrestrial and nearshore marine environments. Isotopic research island has increasingly helped with biological studies of endemic organisms, including evaluating foraging niches investigating factors that affect spatial distribution abundance species. The IsoMad should facilitate future work by making it easy researchers...
Abstract Here, we report the first methodological approach to investigate presence and estimate density of Symbiodiniaceae cells in corals order Antipatharia subclass Hexacorallia, known as black corals. Antipatharians are understudied ecosystem engineers shallow (<30 m depth), mesophotic (30-150 m) deep-sea (>200 reefs. They provide habitat a vast number marine fauna, enhancing supporting coral reefs biodiversity globally. Nonetheless, little biological ecological information exists...
Abstract Mechanical properties of the skeleton four antipatharians (the whip species Cirrhipathes anguina and Stichopathes cf. maldivensis , branched Cupressopathes abies pumila ) living in shallow waters off southwestern coast Madagascar were investigated using a three‐point bending test. The Young's modulus did not differ according to but was significantly higher distal segment colonies, compared with basal median segments. By contrast, flexural stiffness ones, species, other two segments,...
