“…As suggested by Bremner (2008), the initial stage of traits analysis involves the identification of key aspects of functioning in the ecosystem under consideration 255 and the selection of suitable indicator traits. In this perspective, traits that are functionally important have to be selected to provide a relevant picture of the ecosystem functioning.…”

“…Based on the assumption that functional roles performed by species are determined by the species biological traits (Bremner et al, 2006), BTA utilizes species traits (e.g. life history, morphological and behavioral characteristics) as a proxy for functional roles to determine the 100 occurrence of these traits over assemblages (Bremner, 2008). However, Lepš et al (2006) pointed out that the functional diversity of a community is dependent on the context of the study because the number of traits selected and their identity depends on the question asked and on which processes being investigated in the study.…”

In the bay of Concarneau, we investigated the structural (i.e. species richness and species composition) and functional (i.e. biological traits) diversity of the macrofauna associated with this Haploops community as a comparison with several surrounding softsediment communities to determine the effect of this engineer species on ecosystem functions.We showed that the occurrence of Haploops tubes and individuals significantly modify sediment 20 features (e.g. change in sediment grain size, increase in C and N organic content) but also largely affect species diversity and benthic composition. The species richness is significantly higher but most importantly the species assemblage associated with Haploops habitat is very homogeneous and unique with 33% of all species exclusively found in this community. We also tested the effect of tube density on species diversity and abundances and the intermediate disturbance hypothesis but we showed 25 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 2 surprisingly no significant changes.

“…Nematode species in functional groups share several morphological traits (Chalcraft and Resetarits Jr., 2003), and the use of these traits may provide additional information on changes in biodiversity and also facilitate better comparison with other geographical regions (Bremner, 2008). Giere (1993) showed that a classification based on buccal structures of marine nematodes had applications in a variety of marine habitats.…”

Abstract. We studied patterns of nematode distribution along the western Indian continental margin to determine the influence of habitat heterogeneity and low oxygen levels on the community's taxonomic and functional structure. A single transect, perpendicular to the coast at 14 • N latitude was sampled from 34 to 2546 m depth for biological and environmental variables during August 2007. The oxygen minimum zone extended from 102 to 1001 m. Nematodes (described and undescribed) were identified to species and classified according to biological and functional traits. A total of 110 nematode species belonging to 24 families were found along the transect. Three depth zones were identified: the shelf (depth range: 34-102 m; highest nematode mean density: 176.6 ± 37 ind 10 cm −2 ), the slope (525-1524 m; 124.3 ± 16 ind 10 cm −2 ), and the basin (2001-2546 m; 62.9 ± 2 ind 10 cm −2 ). Across the entire study area, the dominant species were Terschellingia longicaudata, Desmodora sp. 1, Sphaerolaimus gracilis, and Theristus ensifer; their maximum density was at shelf stations. Nematode communities in different zones differed in species composition. Chromadorita sp. 2 (2.78 %) and Sphaerolaimus gracilis (2.21 %) were dominant on the shelf, whereas Terschellingia longicaudata (4.73 %) and Desmodora sp. 1 (4.42 %) were dominant on the slope, but in the basin, Halalaimus sp. 1(1.11 %) and Acantholaimus elegans (1.11 %) were dominant. The information in a particular functional group was not a simple reflection of the information in species abundance. Ecological information captured by adult length, adult shape, and life-history strategy was less sitespecific and thus differed notably from information contained in other taxonomic groups. The functional composition of nematodes was strongly linked to the organiccarbon and dissolved-oxygen concentration. Seven species were found exclusively in the oxygen minimum zone: Pselionema sp. 1, Choanolaimus sp. 2, Halichoanolaimus sp. 1, Cobbia dentata, Daptonema sp. 1, Trissonchulus sp. 1, and Minolaimus sp. 1. Correlation with a number of environmental variables indicated that food quantity (measured as the organic-carbon content and chlorophyll content) and oxygen level were the major factors that influenced nematode community structure and function.

“…Hence, alien/invasive species of similar traits are likely to display similar patterns and tendencies within MPAs. Such information may have important implications for the selection of appropriate management actions as well as for comparing different management options (see Bremner, 2008).…”

Marine protected areas (MPAs) have proven to be an effective tool to conserve marine biodiversity and restore ecosystem functioning. Yet, the role of MPAs in providing resilience to global threats, such as biological invasions, is poorly understood. Assessing the effects of MPAs on invasive species is crucial for effective MPA planning and management. We conducted a peer-reviewed literature survey to synthesize all available information on the performance of alien/invasive species in MPAs at a global scale. We also assessed the effects of protection on such species following a meta-analytical approach. We found only 17 studies that were suitable for the qualitative and quantitative synthesis. We included studies that provided data on alien species from both inside and outside MPAs. The largest proportion of the available literature provided data on alien molluscs (40%), followed by algae (28%). Information on the effects of protection on alien/invasive species is available for only 11% of the marine biogeographic provinces; principally, for the Mediterranean and Caribbean Seas. Only four studies provided adequate quantitative data to estimate the effect of protection on the density and biomass of 12 alien species. We found that protection had a significant negative effect on half the species, whereas 33% of the species were positively affected. Our review demonstrates the scarcity of data on this crucial topic. More evidence on various species and taxonomic groups across marine regions is necessary to draw robust conclusions.
