“…Understanding how species distributions and emergent patterns of biodiversity respond to spatial variation in the environment is a dominant theme in ecology and biogeography (Lomolino et al 2010, Rosenzweig 1995). Indeed, some of the most important concepts and notable controversies in environmental biology have emerged from studying gradients associated with latitude (Hillebrand 2004, Willig et al 2003), depth (Hernandez-Alcantara et al 2014, Rex 1981), area (Coleman et al 1982, MacArthur & Wilson 1963, Rosenzweig & Sandlin 1997, Scheiner et al 2011), productivity (Mittelbach et al 2001, Waide et al 1999) or landscape structure (Fahrig 2003, Turner 1989, Turner et al 2001). Similarly, the study of altitudinal gradients (McCain 2005, 2009, Rahbek 1995, Terborgh 1971, Whittaker 1960) has made enduring contributions to the theoretical and empirical bases of modern biology.…”

Abstract:The study of altitudinal gradients has made enduring contributions to the theoretical and empirical bases of modern biology. Unfortunately, the persistence of these systems and the species that compose them is threatened by land-use change at lower altitudes and by climate change throughout the gradients, but especially at higher altitudes. In this review, we focus on two broad themes that are inspired by altitudinal variation in tropical montane regions: (1) dimensions of biodiversity and (2) metacommunity structure. Species richness generally decreased with increasing altitude, although not always in a linear fashion. Mid-altitudinal peaks in richness were less common than monotonic declines, and altitudinal increases in richness were restricted to amphibian faunas. Moreover, gradients of biodiversity differed among dimensions (taxonomic, phylogenetic and functional) as well as among faunas (bats, rodents, birds) in the tropical Andes, suggesting that species richness is not a good surrogate for dimensions that reflect differences in the function or evolutionary history of species. Tropical montane metacommunities evinced a variety of structures, including nested (bats), Clementsian (rodents, bats, gastropods), quasi-Clementsian (reptiles, amphibians, passerines) and quasi-Gleasonian (gastropods) patterns. Nonetheless, compositional changes were always associated with the ecotones between rain forest and cloud forest, regardless of fauna.

“…That is, in Chinchorro Bank, almost all the polychaete species settled in a narrow depth range. Although no formal studies examining this trend have been carried out in the Caribbean Sea, the occurrence of polychaete communities dominated by species with narrow depth ranges had already been reported in soft bottoms' environments (Moreno et al ., 2008; Hernández-Alcántara et al ., 2014). These researchers showed that the depth gradient in the continental shelfs of Chile and the Gulf of California were also defined by a high presence of species with narrow ranges.…”

“…Although polychaete endemism was absent, since all the species identified had already been previously recorded in the Caribbean Sea and around 50% of the studied fauna was common to both transects, the polychaete species had different distribution patterns across the bathymetric gradient. Benthic community changes with depth are well known, but many doubts about their bathymetric patterns and whether the biotic changes associated to depth are gradual or not, still prevail (Hernández-Alcántara et al ., 2014). Mechanisms responsible for bathymetric changes in the number of species have been associated with a wide variety of environmental and biological factors (Gray et al ., 1997), but the presence of species can also vary with small depth changes.…”

The present study is the first attempt to describe beta-diversity patterns in polychaetes of the Caribbean Sea, analysing depth changes in species composition of the Eunicida and Amphinomida inhabiting dead coral in Chinchorro Bank, southern Mexican Caribbean. In April 2008, dead coral fragments were collected by scuba diving in eight stations along two bathymetric gradients (4–9 m and 7–16.2 m depth); 755 individuals from 53 species of the families Amphinomidae, Dorvilleidae, Eunicidae, Lumbrineridae, Oenonidae and Onuphidae were identified. The highest number of species (32) and individuals (514) were found in the family Eunicidae. The Northern transect harboured 36 species, on average 18.75 ind. L−1, which decreased linearly with depth; the Central transect had 43 species, on average 19.01 ind. L−1, which increased at middle depths. The species inhabiting both these zones were moderately different (βsor = 0.603): 49.06% of the fauna occurred on both transects, but the components of beta-diversity, turnover and nestedness, displayed distinct patterns: in the Northern one replacement was the dominant factor (βsim = 0.3–1; βnes = 0–0.091), practically representing all faunal differences (βsor = 0.391–1); in the Central, dissimilarity due to nestedness increased (βnes = 0.031–0.829), mainly at the shallowest stations, but from 5 m depth, beta-diversity was almost completely explained by species replacement (βsim = 0.417–0.5; βnes = 0.031–0.318). Faunal differences were mostly related to higher abundances of Lysidice caribensis, Eunice goodei and Lumbrineris floridana in the Northern zone, and Lumbrineris perkinsi, Nicidion obtusa, Lysidice caribensis, Lumbrineris floridana, Lysidice unicornis and Eunice mutilata in the Central zone.

“…Preliminary data collected mainly by sledges, dredges and box cores indicate that the southeast GoC has an abundant and diverse deep-sea benthic fauna dominated by polychaetes, decapod crustaceans, echinoderms, and mollusks (Hendrickx, 2006;Lluch-Cota et al, 2007;Méndez, 2007;Zamorano et al, 2007;Zamorano and Hendrickx, 2012;Hendrickx and Serrano, 2014;Hernández-Alcántara et al, 2014;Mejía-Mercado et al, 2014;Papiol and Hendrickx, 2016).…”
