“…Wilhelm et al 2003, Häder et al 2007) but, at least in terrestrial ecosystems, the persistence of pathogenic viruses can be greatly influenced by the architecture of plants (via the degree of shading) in conjunction with habitat exposure to UVR (Duffey et al 1995, Raymond et al 2005, Cory & Hoover 2006. Marine flora can act as a reservoir for pathogenic bacteria and fungi (Fuller et al 1964, Mahmud et al 2007, Small & Pagenkopp 2011 and could also be a reservoir for pathogenic viruses. For example, Hernández et al (2005) found that particles of IIV-6 in water underwent a more rapid loss of activity under direct sunlight (99.99% reduction of original activity over a period of 36 h) than in the shade (97% reduction over a period of 60 h).…”

In Bahía de la Ascensión, Mexico, 'casitas' (large artificial shelters) are extensively used to harvest Caribbean spiny lobsters Panulirus argus. After the discovery of a pathogenic virus, Panulirus argus virus 1 (PaV1), in these lobsters, laboratory experiments revealed that PaV1 could be transmitted by contact and through water, and that lobsters avoided shelters harboring diseased conspecifics. To examine these issues in the context of casitas, which typically harbor multiple lobsters of all sizes, we examined the distribution and aggregation patterns of lobsters in the absence/presence of diseased conspecifics (i.e. visibly infected with PaV1) in 531 casitas distributed over 3 bay zones, 1 poorly vegetated ('Vigía Chico', average depth: 1.5 m) and 2 more extensively vegetated ('Punta Allen': 2.5 m; 'Los Cayos': 2.4 m). All zones had relatively high indices of predation risk. Using several statistical approaches, we found that distribution parameters of lobsters were generally not affected by the presence of diseased conspecifics in casitas. Interestingly, however, in the shallower and less vegetated zone (Vigía Chico), individual casitas harbored more lobsters and lobsters were actually more crowded in casitas containing diseased conspecifics, yet disease prevalence was the lowest in lobsters of all sizes. These results suggest that (1) investment in disease avoidance by lobsters is partially modulated by local habitat features, (2) contact transmission rates of PaV1 may be lower in nature than in the laboratory, and (3) water-borne transmission rates may be lower in shallow, poorly vegetated habitats more exposed to solar ultraviolet radiation, which can damage viral particles.

“…Despite their key ecological relevance for carbon cycling on the damp band of sandy beaches, to date there are very limited reports on T. saltator-associated gut microbial flora (Nuti et al, 1971;Martineti et al, 1995). In contrast, several reports on Crustacea-associated microorganisms are present, but mainly linked to health and aquaculture issues (Small and Pagenkopp, 2011;Wang, 2011) or to the presence of Wolbachia infections (Cordaux et al, 2012). There are no investigations on the total microbial communities carried by Crustaceans, despite the fact that in recent years, invertebrate microbiology is attracting more attention for its implication in biocontrol (Natrah et al, 2011) and animalemicrobe interaction studies (Muller et al, 2008;Olson and Kellogg, 2010;Goffredi, 2011).…”

a b s t r a c tThe microbiome present in individuals of Talitrus saltator belonging to seven populations distributed along the Tuscan coast (Italy) was assessed by using Terminal-Restriction Fragment Length Polymorphism (T-RFLP) analysis of amplified 16S rRNA genes. Talitrus saltator is one of the key species of the damp band of European sandy beaches and despite of the large interest on animal-associated bacteria, only a few and preliminary data were present. Results showed a high diversity of the microbiome, composed mainly by members of Alphaproteobacteria, Gammaproteobacteria, Bacillales and Clostridiales classes. The microbiome fingerprints were highly variable among individuals, even from the same populations, the inter-individual differences accounting for 88.7% of total fingerprint variance. However, statistically significant population-specific microbiome signatures were detected, and accounted for the remaining 11.3% of total fingerprint variance. These population-specific differences were mainly attributed to sequences from members of known host-associated bacteria such as Gammaproteobacteria and Betaproteobacteria, Cytophagia and Spirochaetia. This study showed the high complexity of the microbiome associated with an amphipod species and on the inter-individual microbiome variation with potential importance for understanding amphipod trophic and ecologic processes.

“…Marine aggregates, onto which viruses may adsorb, can protect viruses from various sources of inactivation and provide them with a means for horizontal transport, potentially resulting in increased infection of organisms such as zooplankton (Wein bauer et al 2009). Aquatic viruses can also accumulate in submerged macrophytes (Small & Pagenkopp 2011, Sweet et al 2013, wherein the shade may prolong their viability (Hernández et al 2005), as has been suggested for PaV1 in benthic habitats (Briones-Fourzán et al 2012). Interestingly, our neuston net routinely caught large masses of the holopelagic brown algae Sargassum spp., which had to be painstakingly scrutinized for pueruli and phyllosomata.…”

Panulirus argus virus 1 (PaV1), a pathogenic virus that specifically attacks Caribbean spiny lobsters Panulirus argus, was recently detected in newly settled postlarvae of P. argus. As PaV1 appears not to be vertically transmitted, infected postlarvae likely acquire PaV1 from the water, but whether this can occur in oceanic waters where the planktonic larvae (phyllosomata) metamorphose into nektonic postlarvae remains unknown. Late-stage phyllosomata and postlarvae of P. argus were collected at distances of 2 to 100 km from the Caribbean coast of Mexico in 2 oceanographic cruises. Most postlarvae were caught in the upper meter of water, usually along with masses of floating Sargassum algae. A PaV1-PCR assay was used to test 169 phyllosomata (stages VI−X) and 239 postlarvae. All phyllosomata tested negative, but 2 postlarvae, 1 from each cruise, tested positive for PaV1. These postlarvae were collected at 55 and 48 km offshore over depths of 850 and 1800 m, respectively, suggesting that postlarvae can acquire PaV1 in offshore waters. We hypothesize that floating Sargassum may be an environmental reservoir for PaV1. The PaV1 allele (460 pb) found in an infected postlarva was more closely related to PaV1 alleles found in lobsters from Puerto Rico than in lobsters from any other location (including Mexico), suggesting high gene flow and long-distance dispersal of PaV1, consistent with previous studies of high genetic connectivity across the Caribbean.
