ABSTRACT Blue whale locations in the Southern Hemisphere and northern Indian Ocean were obtained from catches (303 239), sightings (4383 records of ≥8058 whales), strandings (103), Discovery marks (2191) recoveries (95), acoustic recordings. Sighting surveys included 7 480 450 km effort plus 14 676 days with unmeasured effort. Groups usually consisted solitary whales (65.2%) or pairs (24.6%); larger feeding aggregations unassociated individuals only rarely observed. rates (groups per 1000...
Abstract Defining priority areas and risk evaluation is of utmost relevance for endangered species` conservation. For the blue whale ( Balaenoptera musculus ), we aim to assess environmental habitat selection drivers, conservation overlap with vessel traffic off northern Chilean Patagonia (NCP). this, implemented a single-step continuous-time correlated-random-walk model which accommodates observational error movement parameters variation in relation oceanographic variables.

After the extensive exploitation that reduced Southern Hemisphere blue whale (Balaenoptera musculus) populations to less than 3% of its original numbers, studies on recovery have been compounded by inaccessibility most and migrations between low high latitudes, thus ensuring knowledge about ecology status remains limited. We report recent discovery of, arguably, important feeding nursing ground known date in Hemisphere, which is located near fjords off southern Chile. Through aerial marine...
The most traditional scheme for migration among baleen whales comprises yearly migrations between productive waters at high latitude summer feeding grounds and warmer lower latitudes where calve mate, but rarely feed. Evidence indicates, however, that large departures from this exist populations individuals. Furthermore, some there is virtually no information on migratory pathways destinations. Such the case of Chilean blue throughout Eastern South Pacific; hence, goal study was to assess...

ABSTRACT Since 2000, an increasing number of humpback whale sightings have been recorded in northern Chilean Patagonia (mostly between 41.5°S and 44°S) from dedicated aerial marine surveys also opportunistic land‐based platforms during austral summer autumn months. Based on local knowledge the early years coastal whaling suggesting historic presence whales area, more recent observations confirming feeding groups, mother–calf pairs, philopatry, it is proposed that a proportion eastern South...

Abstract Blue whales ( Balaenoptera musculus ) were among the most intensively exploited species of in world. As a consequence this intense exploitation, blue whale sightings off coast Chile uncommon by end 20th century. In 2004, feeding and nursing ground was reported southern (SCh). With aim to investigate genetic identity relationship these Chilean those other Southern Hemisphere areas, 60 biopsy samples collected from SCh between 2003 2009. These genotyped at seven microsatellite loci...
Abstract Passive acoustic data were collected January 2012 to April 2013 at four sites in the Chiloense Ecoregion ( CER ) southern Chile (≈43°S–44°S, 71°W–73°W) and 1996–2002 from one site eastern tropical Pacific ETP (8°S, 95°W).

Many aspects of blue whale biology are poorly understood. Some the gaps in our knowledge, such as those regarding their basic taxonomy and seasonal movements, directly affect ability to monitor manage populations. As a step towards filling some these gaps, microsatellite mtDNA sequence analyses were conducted on samples from Southern Hemisphere, eastern tropical Pacific (ETP) northeast Pacific. The results indicate that ETP is differentially used by whales northern southern Pacific, with...
Blue whale populations from both hemispheres are thought to undertake annual migrations between high latitude feeding grounds and low breeding (Mackintosh, 1966). For individuals of some these predetermined movements wintering areas where calving occurs have been confirmed through photo-identification, satellite-tracking, passive acoustic monitoring (Burtenshaw et al., 2004; Mate, Lagerquist, & Calambokidis, 1999; Sears Perrin, 2002; Stafford, Nieukirk, Fox, 1999a). However, for many blue no...
Abstract It is generally assumed that species with low population sizes have lower genetic diversities than larger populations and vice versa. However, this would not be the case for long‐lived long generation times, which declined due to anthropogenic effects, such as blue whale ( Balaenoptera musculus ). This was intensively decimated globally near extinction during 20th century. Along Chilean coast, it estimated at least 4288 whales were hunted from an apparently pre‐exploitation size (k)...

Abstract Aim Species distribution models are useful tools for depicting important habitat, assessing abundance and orienting conservation efforts. For small populations in poorly studied ecosystems, available data often scarce patchy. To overcome this limitation, we aim to evaluate the use of different types within a hierarchical Bayesian framework with goal modelling highly migratory population blue whale ( BW , Balaenoptera musculus ) summering Chilean Northern Patagonian CNP ).

Abstract In the face of environmental degradation, animals with limited plasticity are likely to be most vulnerable. Habitat selection by threatened, endemic Chilean dolphin ( Cephalorhynchus eutropia ) was investigated in northern Patagonian fjords, an area extraordinary biological productivity. Generalized additive models were undertaken assess ecological determinants spatial distribution and habitat selection. Data collected from dedicated fine‐scale marine surveys conducted during...
