Biogeography is defined as the study of life, in a spatial and temporal context, with respect to the analysis and explanation of patterns for a given area. The tendency for species richness and diversity to increases towards the equator, where both peak, is a much debated and tested pattern. Underlying mechanisms thought to cause this pattern are: gradients in temperature, stress, productivity, competition, predation, stability, effective evolutionary time, niche breadth, range size and area of occupancy. Evidence exists that both supports and negates most of these mechanisms. In addition to the richness gradient, a latitudinal gradient in geographical range size exists, whereby species range sizes decrease with latitude, referred to as Rapoport's Rule. This has been linked to species ability to tolerate changes in climate. The latitudinal gradient in species richness is thought to be a by-product of Rapoport's Rule and the "Rescue Effect".

Testo completoCoastal zones are one of the ecosystems receiving higher anthropic impact. Fishing is a major source of human impact, reducing density and size of exploited species. Marine protected areas are one of the strategies established to control fishing impacts. The current artisanal fisheries management system in Chile is based on partially protected areas, TURFs (Territorial Use Right for Fisheries). This system enhances sustainability of one of the traditional activity in the country. However, these areas are individually managed so the scale of resource management is not coupled with the scale of exploited population dynamics. The objective of this thesis dissertation is to identify areas of high value for propagule production as well as source and sink areas based on early life history patterns, considering variables relevant for the adult phase such as (a) reproductive output, (b) density and size of reproductive adults as both variables define the spatial distribution of eggs and larvae, as well as variables that affect the larval phase such as (c) larval biological traits, coupling these pieces of information with coastal circulation models to reach a better understanding of dispersal and larval connectivity. Two benthic invertebrates species exploited by artisanal fisheries in Chile, the red sea urchin (Loxechinus albus) and keyhole limpet (Fissurella latimarginata) were used as models. First, I evaluated the effect of protection and coastal upwelling on reproductive output and individual condition of reproductive adults. Based on size distribution, density of individuals and fecundity data I developed an egg production model along the central coast of Chile. Finally, I developed a biophysical larval dispersal model to assess the effect of oceanographic variability and larval biological traits (larval diel vertical migration and temperature-dependent larval development) on dispersal distance, recruitment success and connectivity patterns. These results showed that fishing regime and coastal upwelling did not affect individual reproductive output either individual condition for both species. However, fishing regime had an effect on size and density of individuals. I found that the geographic and temporal variation in circulation processes dominate transport and effective dispersal of larvae in the study region, regardless of larval biological traits. Most recruitment to local population was allochthonous, with low levels of self-recruitment and local retention even for the species with short planktonic larval duration. Similar geographic patterns of source and destination strengths were observed in both species, with the northern region of the studied domain showing relatively higher importance. These findings allow identifying primary determinants of recruitment success and dispersal distance for two important exploited species in Chile, and to provide the bases to advance recommendations for management and conservation in one the most productive, but also exploited, coastal regions in the world.

Testo completoMost of the seafloor is soft sediment, so hard substrata are isolated and island-like. In this dissertation, I explore how species distribution patterns on isolated marine hard substrata resemble terrestrial island communities, drawing on classical island biogeography theory and assembly rules, and describe how benthic invertebrate communities assemble in these island-like habitats. Higher species richness occurred on larger substrata (dropstones and shipwrecks), paralleling terrestrial island communities. However, while larger islands have greater habitat diversity and primary productivity, marine hard substrata are simpler habitats. Greater elevation in the benthic boundary layer may expose fauna to faster current, higher food supply and larval flux. Substrata located closer together had more similar communities, another pattern that resembles terrestrial islands. Dropstone fauna had a clumped distribution, indicating that larvae may disperse among substrata located close together, resulting in similar communities. In Svalbard fjords, benthic megafaunal communities were significantly different between Arctic- and Atlantic-influenced fjords. Depth and temperature had the greatest influence, with the highest diversity occurring in cold Rijpfjorden and on the north Svalbard shelf. Recruitment in Svalbard fjords was spatially and temporally variable, with lower recruitment in Rijpfjorden than in Atlantic-influenced fjords and lower recruitment at greater depth. Most of the recruits in Svalbard fjords were fast-growing, poor-competitive opportunists. On shipwrecks, communities showed two mechanisms of colonization: mobile fauna with long-dispersing planktotrophic larvae, and encrusting fauna with lecithotrophic larvae. Encrusting species reproduce asexually to cover the wreck surface, and philopatry may build up dense populations, leading to uneven communities. On terrestrial islands, non-random co-occurrence is attributed to interspecific competition, but for marine substrata, there may not be a relationship. Fauna were distributed randomly on settlement plates in Svalbard fjords, even when interspecific competition was observed. On dropstones, some morphotypes co-occurred non-randomly in the absence of overgrowth competition. Non-random co-occurrence on isolated marine hard substrata may be a result of restricted larval dispersal (for pairs co-occurring less than by chance) or epibiontism (for pairs co-occurring more often than by chance). While species distribution patterns on island-like marine hard substrata resemble terrestrial islands, the mechanisms are not necessarily the same.

Testo completoPharmaceutical research and development strategies rely on the constant discovery of novel natural products as potential drugs. Recent studies have shown that the microorganisms associated with sponges are the true producers of some previously isolated compounds. This study created a large collection of bacterial symbionts associated with the South African marine sponge, Hamacantha esperioides. The bioactivity assays performed, showed that 44 isolates produced compounds with antimicrobial or anti-inflammatory activity. The successful identification of novel species that produce potential natural products highlights the importance of cultivation-dependent methods. To further screen for natural products, a cultivation-independent approach was used. A sequenced-based method, based on the biosynthetic genes of polytheonamide, was developed to screen for proteusins in sponge metagenomic DNA and the genomes of bacterial symbionts. The degenerate primers could amplify the targeted genes from DNA known to contain homologues. Evaluation of the primers' specificity showed non-specific amplification of genes, some containing similar conserved domains as the target genes. This study demonstrated that the use and development of cultivation-dependent and -independent screens are important for the discovery of novel natural products from the symbiotic bacteria of South African sponges.

Testo completoHowever, evidence of regeneration was observed between 58 and 86 days after noise exposure. Behavioural observations suggested that as air-gun noise levels increase, fish respond by swimming faster, in tighter groups and towards the bottom of the water column. Significant increases in alarm responses were observed in fish and squid to air-gun noise exceeding 158 - 163 dB re 1μPa. An increasing proportion of alarm responses were also observed as the noise level increased. A decrease in the frequency of alarm responses for repeated exposures was observed in squid and some fish. The implications of these findings are discussed with comparisons of noise levels measured from an actual 2678 cui seismic survey air-gun array.

Testo completoThe work carried out in this thesis explores the various possible contributions of taxonomic inventories of marine macroscopic invertebrates, whether they are interested in a particular taxonomic group or the biodiversity of species in a habitat, in order to bring knowledge but also to respond to management problems such as: What species to protect? What habitat to protect? Which invasive alien species to eradicate?The first aspect of this work is the inventory of species by taxonomic group and the multitaxon inventory for an area, in order to assess its biodiversity. In the first part, two of the taxonomic inventories are centered on taxonomic groups, they are carried out in collaboration with specialists and concern the taxonomic inventory of hydraries and that of gorgonians. The second part uses simplified inventories, focusing on the majority of taxa, but focused on specific areas in order to assess their biodiversity: A study concerns the marine parts that are close to the mangroves, and the second study at the caye “Grande Sèche” in the heart of the bay of Fort-de-France. In a third part, species biodiversity inventories are used to update the typology of benthic marine habitats, using data collected during the Madibenthos Expedition (MNHN) and in photographs taken by the participants. And in the final part, the multitaxons inventories carried out throughout Martinique are used to evaluate which species of invertebrates are rare in Martinique and that can be candidates for protection or species status determining the establishment of ZNIEFF.The second aspect of this work is the inventory of protected species of macroscopic invertebrates, including corals, whose population status is of concern, in order to map their distribution and assess sources of pressures and threats. First, it is indicated the development of a method that allowed to map a small protected coral species, Oculina diffusa. The study shows that the habitat of this species is very specific and that it is under many pressures. Second, a method using different remote sensing and in situ inventory techniques was developed to map the distribution of large coral species (Orbicella favelolata, O. annularis, O. franksii) on a caye. Finally, in a third phase, the results of multitaxon inventories have helped to characterize the rarity or low abundance of certain coral species in Martinique, results that have worked towards the protection of corals..The third axis focuses on the inventory of non-native species and invasive alien species of macroscopic invertebrates to map their distribution and assess their impacts on native species and their habitats. The study presents three non-native species, some of which are certified as invasive alien species or are being evaluated for others. The first species presented, studied in 2015, is an invasive crab Charybdis hellerii. The study of this species made it possible to report its presence for the first time in the Lesser Antilles. The biometric study of populations and sex ratios has helped to characterize the population. A study of occupied habitat allows for a better study of its impact and better targeting of the habitats to be monitored. The second species is a non-native ophiure, Ophiothela mirabilis, studied in 2017 on the Atlantic coast of Martinique. Finally the third species studied is a non-native coral, Tubastraea coccinea, its population has increased in recent years, a first mapping is proposed. This study was conducted at the very beginning of the expansion of the non-native species, it specifies the number of species of host gorgonians and the maximum colonization density reached in some gorgonians. The results obtained during these inventories have provided a more accurate view of the state of marine biodiversity, they have contributed to the protection of species and areas. They should contribute to better management and protection of the marine environment in Martinique
