Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific (open access)

Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific

From introduction: The purpose of this report is to present a sensitivity analysis on the effects that biased sampling of young calves and lactating females would have on the various estimated life history parameters. This sensitivity analysis provides one measure of reliability of the various estimates. Also, where inconsistencies in the estimates can be identified, this analysis provides one means for evaluating which estimates are likely in error.

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985 (open access)

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985

Abstract: Research on the Laysan Island population of the endangered Hawaiian monk seal, Monachus schauinslandi, was conducted from 2 march to 30 November 1985. census totals excluding pups ranged from 76 to 147, an average increase of nearly 20 animals from the 1984 census results. Overall monthly haul-out distribution for all seals showed highest use in the north ecological unit followed by the west unit. Relatively few animals hauled out in the eastern and southern portions of the island. Interatoll movement of nine seals was documented, resulting in a net increase of three animals to the Laysan Island population.

This report describes data collected during an observational study on the Hawaiian monk seal on Laysan Island during April 23 to July 21 1983. The data collected is on population size, reproduction, and factors affecting survival of the endangered species. There is also a description of a "mobbing" by adult males, resulting in death of a subadult female; the haul out of seals on the south ledge; and the transport of a juvenile male to Honolulu to initiate a captive research program.

Hawaiian Monk Seal Reproduction and Injuries on Lianski Island, 1982 (open access)

Hawaiian Monk Seal Reproduction and Injuries on Lianski Island, 1982

Abstract: data on the Hawaiian monk seal, Monachus schnauinslandi, including pup production, pupping locations, and injuries at Lisianski Island in 1982 are presented. Twenty-eight pups were born, of which 26 survived to weaning. Of the observed births, 75% occurred on the east side of the island. Average nursing period for 14 mother-pup pairs was 37.4 days. One exchange of pups was observed. Ten seals were injured while personnel were present on the island. Four of these injuries were attributable to attacks by adult male seals.

The Hawaiian Monk Seal and Green Turtle on Necker Island, 1983

Abstract: Between 24 July and 6 August 1983, a two-person National Marine Fisheries Service field camp examined the Hawaiian monk seal, Monachus schauinslandi, and green turtle, Chelonia mydas, populations of Necker Island. Forty-three seals were identified, photographic records for seal identification were made, and 21 animals were bleach marked. Of three pups at Necker, only one weaned during the study period and was tagged. A pregnant femals was found dead and a necropsy was performed. Eighty-eight turtle observations included feeding (59), basking (18), and swimming (11) sightings. Four turtles were individually identified; three of these were flipper-tagged.

Species Profiles: Life Histories and Environmental Requirements of Coastal Vertebrates and Invertebrates Pacific Ocean Region, Report 1, Green Turtle, Chelonia mydas (open access)

Species Profiles: Life Histories and Environmental Requirements of Coastal Vertebrates and Invertebrates Pacific Ocean Region, Report 1, Green Turtle, Chelonia mydas

Abstract: Species profiles are literature summaries of the taxonomy, morphology, distribution, life history, and environmental requirements of aquatic species. They are designed to assist in environmental impact assessments. The green turtle, Chelonia mydas, is found throughout the Pacific Ocean region. Its status is listed as endangered by the International Union for Conservation of Nature and Natural Resources and as threatened in the U.S. Endangered Species Act and is included in Appendix 1 of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Females nest on a 20,3-, or >4-year cycle, laying one to six clutches per season and averaging between 100 and 110 eggs per clutch. Nesting normally takes place in the summer months. Hatching mortality from predation in the marine environment is thought to be high. After an initial >3-year carnivorous pelagic stage, green turtles become primarily herbivores, residing in shallow coastal areas where they feed on sea grass and/or algae. Growth rates appear to vary with diets and are generally slow. Turtles average 25 years to reach sexual maturity in Hawaii. Adult green turtles are long-lived and have few predators other than man. The use of modern equipment in hunting turtles and the disregard …
