We report on a wintering area off the Pacific coast of Central America for humpback whales ( Megaptera novaeangliae ) migrating from feeding areas Antarctica. document seven individuals, including mother/calf pair, that made this migration (approx. 8300 km), longest movement undertaken by any mammal. Whales were observed as far north 11° N Costa Rica, in an also used boreal population during opposite winter season, resulting unique spatial overlap between Northern and Southern Hemisphere...
A bstract Despite the extensive use of photographic identification methods to investigate humpback whales in North Pacific, few quantitative analyses have been conducted. We report on a comprehensive analysis interchange Pacific among three wintering regions (Mexico, Hawaii, and Japan) each with two subareas, feeding areas that extended from southern California Aleutian Islands. Of 6,413 photographs obtained by 16 independent research groups between 1990 1993 examined for this study, 3,650...
Species distribution models that predict species occurrence or density by quantifying relationships with environmental variables are used for a variety of scientific investigations and management applications. For endangered species, such as large whales, help to understand the ecological factors influencing variability in distributions assess potential risk from shipping, fishing, other human activities. Systematic surveys record presence absence, well associated search effort, but very...

A bstract Here, we examine the distribution, habitat use, and migratory destinations of North Pacific humpback whales wintering off Central America. Coastal boat surveys were conducted Costa Rica Panama between 1996 2003. In 1999, a broader survey was along most Over 23,000 km surveyed, with greatest effort southern Rica. We made 191 sightings 320 individual whales. Whales seen 14°N 8°N, making this southerly areas. Encounters included singles, adult pairs, singers, mother/calf pairs....
Abstract Latitudinal preferences within the breeding range have been suggested for Breeding Stock G humpback whales that summer in different feeding areas of eastern South Pacific. To address this hypothesis, photo‐identified from Antarctic Peninsula and Fueguian Archipelago (southern Chile) were compared with lower latitudes extending northern Peru to Costa Rica. This comparison was performed over a time span includes 18 austral seasons. A total 238 identified 25 among those at grounds. Our...
Historical summer feeding and winter breeding grounds of humpback whales in the southeast Pacific (Megaptera novaeangliae) have been recorded west Antarctic Peninsula during austral off Ecuador Colombia (Kellogg 1929, Mackintosh 1965, Flórez-González et al. 1998, Scheidat 2000, Félix Haase 2001). In recent years, found further north, Panama Costa Rica (Acevedo Smultea 1995; 1998; Rasmussen, personal observation), areas also frequented by northeast boreal (Steiger 1991). Furthermore species...
Abstract Humpback whales ( Megaptera novaeangliae ) are a cosmopolitan species and perform long annual migrations between low-latitude breeding areas high-latitude feeding areas. Their populations appear to be spatially genetically segregated due long-term, maternally inherited fidelity natal In the Southern Hemisphere, some humpback whale mix in Ocean waters summer, but very little movement Pacific Atlantic has been identified date, suggesting these constituted an oceanic boundary distinct...
Familial adenomatous polyposis (FAP) is a human cancer syndrome characterized by the development of hundreds to thousands colonic polyps and extracolonic lesions including desmoid fibromas, osteomas, epidermoid cysts, congenital hypertrophy pigmented retinal epithelium. Afflicted individuals are heterozygous for mutations in APC gene. Detailed investigations mice ortholog Apc have shown that other genetic factors strongly influence phenotype. Here we report qualitative quantitative...
Keywords: population dynamics, breeding areas, migration patterns, sightings, threats.
Introduction: Worldwide, false killer whales (Pseudorca crassidens) are infrequently encountered, yet long-term studies have shown strong site fidelity as well associations among individuals in several locations. Detailed of this species primarily been conducted around tropical oceanic islands or the subtropical southern hemisphere.
 Objectives: We assess movements and association patterns along Pacific coasts USA, Mexico, Guatemala, Nicaragua, Costa Rica including Isla del Coco,...
Introduction: Even though they occur worldwide in tropical and subtropical waters, Bryde’s whales (Balaenoptera edeni) are one of the most enigmatic all balaenopterid species. Previous research has reported presence off Pacific coast Panama, but little is known about their behaviors, abundance, distribution these waters.
 Objective: We report on an area Gulf Chiriqui, where have regularly been sighted.
 Methods: conducted small-boat surveys for marine mammals Chiriqui between 2001...
