Study on the Gembrong Goat Inbreeding in Tumbu Village, Indonesia

Gembrong goat is an Indonesian breed originating from Bali Province that is very rare, having a high level of inbreeding. The inbreeding coefficient (Fis), inbreeding rate (IR), and inbreeding probability (PI) values of Gembrong goat were estimated in Tumbu village, Bali province, Indonesia. Previous studies provide data on the pedigree records of goats in 2015. According to research, the Fis value of Gembrong goats at Tumbu village was 0.413, putting them in the high category (Fx > 0.125). The IR value in the Gembrong population at Tumbu village was 0.025, putting it in the high group (IR > 0.020). The PI value in the F1 Gembrong population was 0.184, which was in the low category (PI 0.50). In conclusion, the elevated Fis and IR values in Gembrong goats were caused by a small population size. In the future, the Gembrong goat recording system will be critical for reducing inbreeding.

Abstract Eumops floridanus (Allen, 1932) is a molossid commonly called the Florida bonneted bat or the Florida mastiff bat. Eumops floridanus is the largest species of bat in Florida and is one of 16 species in the genus Eumops. With one of the smallest distributions of any bat in the United States, it is endemic to southern peninsular Florida where it roosts in cavities of live and dead trees and man-made structures. Eumops floridanus was formerly classified as a subspecies of E. glaucinus but has been elevated to species level based on morphology. Due primarily to its restricted distribution, small population size, and the continued loss of habitat, E. floridanus is federally listed as “Endangered” (EN) by the United States Fish and Wildlife Service.

This special issue of Practicing Anthropology includes seven papers which cover a broad spectrum of anthropological practice in Alaska, but share a common orientation toward public policy. We have chosen to focus on anthropology and public policy in Alaska for several reasons. First, there appears to be a high level of anthropological involvement in and impact on Alaskan public policy compared to other regions of the United States. Second, that involvement and influence is not limited to one or two topics but ranges over a variety of issues. Finally, we feel that because of the nature of contemporary Alaska—its size, small population, ethnic diversity, present economy, and youth as a state—public directions taken at this time will be crucial to the future of the people who are presently residents of Alaska. A sense of that urgency as well as of the powerful forces at work comes through in a number of the articles.

Pseudorca Crassidens

Introduction: False killer whale (Pseudorca crassidens) is a tropical and subtropical social species that live in groups with individuals of mixed ages and sex classes. False killer whales have been documented since the late 1990s in Southwestern Costa Rica. Objective: To estimate the abundance of false killer whales in Osa Peninsula waters. Methods: Cetacean surveys off the Osa Peninsula Waters (OPW), Costa Rica, yielded opportunistic encounters with false killer whales in Drake Bay and Caño Island (2001-2015) and observations during formal surveys in Golfo Dulce (2005-2015). Photo-identification data was analyzed using capture-mark-recapture models in the study area, through an open population (POPAN) framework, considering the effect of time on the parameters apparent survival and capture probability, producing an abundance estimate for a superpopulation in the entire study area. Results: False killer whale abundance in OPW is characterized by a small population size of no more than 100 individuals, complemented by a very low probability of encounter and a contrasting high apparent survival. Conclusions: This population estimate should be taken as conservative, however, the small population size of less than 100 individuals should be considered vulnerable, in contrast to the increasing anthropogenic impacts in the coastal seascape. We argue the potential occurrence of population units along the coastal seascape of the Pacific littoral and oceanic island-associated units at Isla del Coco.

Historical Past

Until the present millennium, very little creative literary writing in either English or Spanish had been published in the British colonial enclave of Gibraltar. Given the small population size of the autonomous community of some 30,000 people, it was considered unlikely that a “national” literary culture could form. In the course of the past decade, a handful of dedicated writers have published a noticeable amount of fiction, all of which is concerned with establishing a recognized Gibraltarian literary identity. The present article, while not arguing for the permanence of a Gibraltarian national literary culture, attempts to trace some of the ways in which a small, unified, geopolitical territory has attempted to tell its own story.
