Harmful algae blooms (HABs) cause acute effects on marine ecosystems due to their production of endogenous toxins or enormous biomass, leading significant impacts local economies and public health. Although HAB monitoring has been intensively performed at spatiotemporal scales in coastal areas the world over last decades, procedures have not yet standardized. are complicated consist many methodologies, including physical, chemical, biological water sample measurements. Each program currently...
RESUMENEl considerar a Cygnus melanocoryphus como un herbívoro generalista que se alimenta de las algas y pastos marinos más abundantes en los humedales -entre ellos costeros -que habita, permite suponer la existencia interacciones aún no reportadas entre esta ave acuática cultivadores marinas del sur Chile, por ello el objetivo este estudio fue conocer alimentación C. humedal marino donde tradicionalmente ha realizado cultivo alga pelillo (Gracillaria chilensis).El trabajo desarrolló...
Harmful algae blooms (HABs) monitoring has been implemented worldwide, and Chile, a country famous for its fisheries aquaculture, intensively used microscopic toxin analyses decades this purpose. Molecular biological methods, such as high-throughput DNA sequencing bacterial assemblage-based approaches, are just beginning to be introduced in Chilean HAB monitoring, the procedures have not yet standardized. Here, 16S rRNA 18S metabarcoding HABs stepwise. According recent hypothesis,...
The Reloncaví estuary in southern Chile is famous for its aquaculture. However, recurring harmful algal blooms have adversely affected mussel production. Therefore, regular monitoring of toxins urgently needed to better understand the contamination status estuary. In this study, we quantified 15 types lipophilic shellfish Metri Bay on a biweekly basis 4 years. We identified species using microscopy and metabarcoding analysis. also measured water temperature, salinity, chlorophyll-a,...
The dinoflagellate Alexandrium catenella is a well-known paralytic shellfish toxin producer that forms harmful algal blooms, repeatedly causing damage to Chilean coastal waters. causes and behavior of blooms are complex vary across different regions. As bacterial interactions with species increasingly recognized as key factor driving the present study identifies several candidates potentially associated . This research narrowed down selection bacteria from A. culture using antibiotic...
We describe the synanthropic behavior of Lontra felina along its geographic distribution.The marine otter used fishing ports infrastructure for shelter and food.It forages on remains fish discarded by fishermen.Identified threats to conservation this species in synanthropy include incidental mortality fisheries persecution domestic animals.The opportunities are creating niche food shelter, which favor permanence population growth.Finally, we identify important variables consider future...

The Chilean flamingo (Phoenicopterus chilensis) is an endemic aquatic bird of South America.In Chile, it found in both highland lagoons as well marine wetlands.Nevertheless, dietary studies environments are scarce.This work characterized the interannual variation winter diet flamingos wetland Bahía Caulín, southern Chile.To this end, we determined size prey items consumed between June and September 2011, 2014 2015.A total 157 feces were analyzed (77 2011 80 2015).The during was carnivorous...
The imperial cormorant (Phalacrocorax atriceps) is one of the most abundant species in Chilean channels and fjords. Although its reproductive non-reproductive distributions have been studied, works on diet are inexistent. This paper describes determines dominance diversity prey consumed during winter periods 2011 2014 Caulín Bay, Chiloé, southern Chile. A total 73 pellets were collected (30 43 2014). Prey identified classified into three categories: fishes (53.57%), cephalopods (39.29%)...
The globally population decline of Southern Rockhopper penguins does considered this species as v ulnerable.However, in the Diego Ramírez archipelago (southern Chile) during recent years breeding has been increased.We describe nesting two sub-colonies conformation Gonzalo Island, Ramírez.Variables such sub-colony size and location nest within not explain hatching success eggs survival chicks.The penguin Island a pattern expansion its colony, explained by local increase abundance protection...
Marine wetlands are intertidal areas with depths less than six meters, which stand out for their high biodiversity and the ecosystem services they offer. They important environments various species of aquatic birds, especially those belonging to Anatidae family, includes ducks, swans geese. The objective this work was study diversity waterfowl present in Caulín marine wetland, located Chiloé, southern Chile. During winter seasons 2012, 2014 2015, monitored using transect technique. wetland...
The Lafken Mapu Lahual Coastal Marine Protected Area of Multiple Uses (Lafken Lahual), Osorno coast, southern Chile, is one the first protected areas created in Chile during 2006, but only 2019 its Management Plan was presented. This study provides information on marine mammal species to be used future biodiversity monitoring plans. sighted mammals were recorded and counted through 18 navigation tracks observation point 2014-2015 austral breeding season. Five systematically (one whale...
Resumen ∙ El presente trabajo provee información sobre la dieta de subadultos Pato Quetru no Volador (Tachyeres pteneres) en cuatro islas del sur Chile durante los periodos estivales años 2007, 2009, 2012, 2013 y 2014. Se colectaron 293 fecas centro Chile: Isla Guamblin, isla Guapiquilán, Lacaos e Guafo. comparó el consumo presas entre islas. identificaron 686 restos duros invertebrados vertebrados marinos algas. Los cangrejos (Cancridae) se registraron como presa más consumida las número...
El Ostrero Pardo (Haematopus palliatus) y el Negro (H. ater) se distribuyen en todo Chile. Al presente, no existe información publicada sobre la biología reproductiva de estas dos especies osteros para Región Los Lagos, sur En este trabajo presentamos registros nidificación islas Caicura, Seno Reloncaví, Obtuvimos fenología, número nidos, huevos polluelos durante tres temporadas reproductivas consecutivas. general, puesta ambas (dos por nido uno Negro) comenzó noviembre observaron...
