Anthropogenic Marine Debris (AMD) in the SE Pacific has primarily local origins from land-based sources, including cities (coastal and inland), beach-goers, aquaculture, fisheries. The low frequency of AMD colonized by oceanic biota (bryozoans, lepadid barnacles) suggests that most litter items coastal waters Humboldt Current System (HCS) are pulled offshore into South Subtropical Gyre (SPSG). highest densities floating micro- macroplastics reported SPSG. An extensive survey photographic...
Some species of macroalgae continue to live for extended periods time after detachment and may even maintain reproductive structures, yet very little is known about this process. Here, we describe the presence sporophylls (with sporogenous tissues) on floating kelp rafts Macrocystis spp. along coast Chile. Surveys were conducted at nine sites (18–50° S) during austral summer 2002, seen collected seven these (between 22 50° S). Fifteen (26.8%) 56 samples had sporophylls, indicating...
Macroalgal rafts frequently occur floating in coastal waters of temperate regions the world's oceans. These are considered important dispersal vehicles for associated organisms with direct development. However, environmental factors may limit potential kelp and thereby organisms. To examine effect water temperature grazing on growth, reproductive output, survival Macrocystis spp., experiments were conducted outdoor tanks during austral summer 2006/2007 at three sites along Chilean Pacific...
Litter from anthropogenic sources is commonly observed on beaches in the SE Pacific.The composition of litter found shore suggests that most it has passed relatively little time at sea, and mostly local sources.In southern Chile, stray items aquaculture installations comprise garbage, whereas central northern Chile Peru, general household common.Abundances are highest areas with intense human activities, i.e. harbors, cities, centers.Impacts marine life observed, but have not been...
Coastal marine upwelling famously supports elevated levels of pelagic biological production, but can also subsidize production in inshore habitats via pelagic-benthic coupling. Consumers inhabiting macroalgae-dominated rocky reef are often considered to be members a food web fuelled by energy derived from benthic primary production; conversely, they may subsidized materials transported habitats. Here, we used stable isotopes (δ13 C, δ15 N) examine the relative contribution and an...
Abstract Aim The abundant‐centre hypothesis (ACH) is based on the assumption that physiological constraints limit populations at edges of their distributional range, yet geographical variation performance or life‐history traits has rarely been examined. Here we examine applicability ACH in a marine system by testing whether predictions are reflected large‐scale variations traits. Location Chilean coast (18°–42° S), encompassing more than 2500 km along Pacific South America. Methods Five...
During ontogeny, male rock shrimp Rhynchocinetes typus develop from the morphotype through several intermedius stages to robustus morphotype, last molt stage, which features powerful third maxillipeds and chelae. In a competition-free environment, all mate in similar manner. They guard females for 23 min 3 h perform behaviors before after they transfer spermatophores. present study, we observed mating behavior of three different ontogenetic competitive environment competed directly access...
During summer 2009, we conducted a field experiment and survey at 30°S in the coastal Humboldt Current to determine how floating time affects physiological performance of kelp rafts. For rafts were tethered waters was specifically designed collect free‐floating Macrocystis pyrifera across latitudinal temperature gradient that reflects natural time. Experimental kelps kept under photosynthetic active radiation (PAR) PAR + ultraviolet (UV; UV) using filter foils, sea surface their habitat....
Rafts of Macrocystis pyrifera (L.) C. Agardh can act as an important dispersal vehicle for a multitude organisms, but this mechanism requires prolonged persistence floating kelps at the sea surface. When detached, become transferred into higher temperature and irradiance regimes surface, which may negatively affect kelp physiology thus their ability to persist long periods after detachment. To examine effect water herbivory on photosynthetic performance, pigment composition, carbonic...
Abstract Kelp habitats provide food, refuge, and enhance the recruitment of commercially important marine invertebrates. The southern rock lobster, Jasus edwardsii, supports valuable fisheries in Australia New Zealand. once covered large areas inshore reef around Tasmania, Australia, but coverage has reduced over last few decades due to climate change, especially off eastern coast island. We investigated whether kelp influences settlement lobster post-larvae artificial collectors how...

The mating behavior and fertilization capacity of three different ontogenetic stages male rock shrimp Rhynchocinetes typus were examined. first stage is the morphotype, which similar in morphology to female. last stage, robustus characterized by extremely long third maxillipeds powerful chelae. During development between these two morphs, males undergo several intermediate molts, are termed "intermedius." In experiments with pairs single females, all (typus, intermedius, robustus) behaved a...
