Here we examined ... -
Daily accumulation rates of marine litter on the shores of Rapa Nui (Easter Island) in the South Pacific Ocean
Thiel, Martin; Barrera Lorca, Bárbara; Bravo, Luis; Hinojosa Toledo, Iván Andrés; Zeballos Meneses, Hugo (2021-08)Large amounts of floating litter accumulate in the subtropical gyres, and the shorelines of oceanic islands in the vicinity of these accumulation zones receive large amounts of litter. The dynamics of marine litter arrival ... -
Epibiont communities on stranded kelp rafts of Durvillaea antarctica (Fucales, Phaeophyceae)—Do positive interactions facilitate range extensions?
López, Boris A.; Macaya, Erasmo C.; Rivadeneira, Marcelo M.; Tala, Fadia; Tellier, Florence; Thiel, Martin (2018)Aim: This study examines how rafting on floating bull kelps can shape the biogeographic patterns of raft-associated species, and analyses the spatio-temporal variability of taxonomic richness and co-occurrences of epibionts ... -
Impacts of marine plastic pollution from continental coasts to subtropical gyres—fish, seabirds, and other vertebrates in the SE Pacific
Thiel, Martin; Luna-Jorquera, Guillermo; Álvarez-Varas, Rocío; Gallardo, Camila; Hinojosa, Iván A.; Luna, Nicolás; Miranda-Urbina, Diego; Morales, Naiti; Ory, Nicolas; Pacheco, Aldo S.; Portflitt-Toro, Matías; Zavalaga, Carlos (2018-07-24)Anthropogenic Marine Debris (AMD) in the SE Pacific has primarily local origins from land-based sources, including cities (coastal and inland), beach-goers, aquaculture, and fisheries. The low frequency of AMD colonized ... -
Inter-hemispherical shoreline surveys of anthropogenic marine debris - A binational citizen science project with schoolchildren
Honorato Zimmer, Daniela; Kruse, Katrin; Knickmeier, Katrin; Weinmann, Anna; Hinojosa, Ivan A.; Thiel, Martin (2019-01)Anthropogenic marine debris (AMD) is a global problem and the identification of its sources is essential for adequate mitigation strategies. Herein we examined whether AMD density and composition differed between two ... -
Mini-symposium: Behavioral ecology of crustaceans
Thiel, Martin; Paschke, Kurt; Palma, Álvaro (2003)Crustaceans are common and conspicuous in a wide range of environments, particularly in the marine realm. Despite their high diversity and abundance, many aspects of their natural history and general biology remain little ... -
Spatio-temporal variation of anthropogenic marine debris on Chilean beaches
Hidalgo-Ruz, Valeria; Honorato-Zimmer, Daniela; Gatta-Rosemary, Magdalena; Nuñez, Paloma; Hinojosa, Iván A.; Thiel, Martin (2018-01)We examined the hypothesis that in an emerging economy such as Chile the abundances of Anthropogenic Marine Debris (AMD) on beaches are increasing over time. The citizen science program Científicos de la Basura (“Litter ... -
Species separation within the Lessonia nigrescens complex (Phaeophyceae, Laminariales) is mirrored by ecophysiological traits
Koch, Kristina; Thiel, Martin; Tellier, Florence; Hagen, Wilhelm; Graeve, Martin; Tala, Fadia; Laeseke, Philipp; Bischof, Kai (2015)Lessonia nigrescens used to be an abundant kelp species along the Chilean coast, but recent molecular studies revealed the existence of a L. nigrescens species complex, which includes the two cryptic species ...
