Abstract. Echinoids comprise an integral component of coral reef ecosystems, providing trophic links, microhabitats, and refuge for a wide diversity of symbiotic organisms. We studied the association of at least eight species of decapod crustacean ectosymbionts with six species of echinoids at Roatán, Honduras, during 6-11 September 2015. Decapods associated most frequently with the echinoid Diadema antillarum (10.80% of individuals of this echinoid, six decapod species; n 799), followed by Eucidaris tribuloides (1.74%, three species; n 746), Echinometra lucunter (1.30%, six species; n 8349), Tripneustes ventricosus (0.86%, four species; n 1167), Echinometra viridis (0.23%, two species; n 862), and Lytechinus variegatus (0%, no species; n 12). Of 239 individual decapods observed, Percnon gibbesi was the most common species (48.5% of decapods, four echinoid species), followed by unidentified hermit crabs (Paguridae; 27.2%, five species), Stenorhynchus seticornis (11.7%, three species), Stenopus hispidus (6.3%, three species), Plagusia depressa (3.3%, three species), Panulirus argus (1.3%, one species), an unidentified small crab (possibly Pitho sp.; 1.3%, one species), and Mithrax verrucosus (0.4%, one species). The frequency of association varied with water depth for P. gibbesi, which associated more frequently with D. antillarum in shallow water ( 5 m), and S. seticornis, which associated more frequently with D. antillarum in deep water ( 5 m). None of the decapod species associated exclusively with echinoids or was specialized for associating with echinoids. Decapods associated with the longest-spined species, D. antillarum, at a rate more than six times higher than that of any other echinoid species, supporting the hypothesis that decapods seek shelter among the spines of echinoids to benefit from decreased predation.

The North American-Caribbean Plate boundary in Mexico-Guatemala-Honduras

et al. 2009

New structural, geochronological, and petrological data highlight which crustal sections of the North American–Caribbean Plate boundary in Guatemala and Honduras accommodated the large-scale sinistral offset. We develop the chronological and kinematic framework for these interactions and test for Palaeozoic to Recent geological correlations among the Maya Block, the Chortís Block, and the terranes of southern Mexico and the northern Caribbean. Our principal findings relate to how the North American–Caribbean Plate boundary partitioned deformation; whereas the southern Maya Block and the southern Chortís Block record the Late Cretaceous–Early Cenozoic collision and eastward sinistral translation of the Greater Antilles arc, the northern Chortís Block preserves evidence for northward stepping of the plate boundary with the translation of this block to its present position since the Late Eocene. Collision and translation are recorded in the ophiolite and subduction–accretion complex (North El Tambor complex), the continental margin (Rabinal and Chuacús complexes), and the Laramide foreland fold–thrust belt of the Maya Block as well as the overriding Greater Antilles arc complex. The Las Ovejas complex of the northern Chortís Block contains a significant part of the history of the eastward migration of the Chortís Block; it constitutes the southern part of the arc that facilitated the breakaway of the Chortís Block from the Xolapa complex of southern Mexico. While the Late Cretaceous collision is spectacularly sinistral transpressional, the Eocene–Recent translation of the Chortís Block is by sinistral wrenching with transtensional and transpressional episodes. Our reconstruction of the Late Mesozoic–Cenozoic evolution of the North American–Caribbean Plate boundary identified Proterozoic to Mesozoic connections among the southern Maya Block, the Chortís Block, and the terranes of southern Mexico: (i) in the Early–Middle Palaeozoic, the Acatlán complex of the southern Mexican Mixteca terrane, the Rabinal complex of the southern Maya Block, the Chuacús complex, and the Chortís Block were part of the Taconic–Acadian orogen along the northern margin of South America; (ii) after final amalgamation of Pangaea, an arc developed along its western margin, causing magmatism and regional amphibolite–facies metamorphism in southern Mexico, the Maya Block (including Rabinal complex), the Chuacús complex and the Chortís Block. The separation of North and South America also rifted the Chortís Block from southern Mexico. Rifting ultimately resulted in the formation of the Late Jurassic–Early Cretaceous oceanic crust of the South El Tambor complex; rifting and spreading terminated before the Hauterivian (c. 135 Ma). Remnants of the southwestern Mexican Guerrero complex, which also rifted from southern Mexico, remain in the Chortís Block (Sanarate complex); these complexes share Jurassic metamorphism. The South El Tambor subduction–accretion complex was emplaced onto the Chortís Block probably in the late Early Cretaceous and the Chortís Block collided with southern Mexico. Related arc magmatism and high-T/low-P metamorphism (Taxco–Viejo–Xolapa arc) of the Mixteca terrane spans all of southern Mexico. The Chortís Block shows continuous Early Cretaceous–Recent arc magmatism.

“…Ú tila, Roatá n, and other smaller islands form the emergent crest of the continental Bonacca ridge along the Motagua/Swan Islands Fault Zone between the North American and Caribbean plates. Ú tila is partly formed by basalts from a Quaternary volcano, whilst Roatá n and adjacent islands are largely composed of older metamorphic rocks comparable to those in Guatemala, with most recent folding around the Late Eocene, with exhumation and Tela Basin subsidence in the Miocene [26,27]. Cayos Cochinos consists of granite intrusions within metamorphic rocks.…”
