The application of randomly amplified polymorphic DNA (RAPD's) to the study of Lasaea rubra (Montagu).

This paper describes the random amplification of polymorphic DNA markers (RAPDs) in Lasaea rubra (Erycinidae: Bivalvia). Present evidence suggests that L. rubra is an asexual species; however, the exact mode of clonal reproduction in this species is still a matter of debate. In this preliminary study, four of the primers used generated polymorphic RAPDs. One primer was able to distinguish between individuals from the same or different crevice population. This same primer also resolved a single band difference between otherwise identical RAPD patterns of a parent and its offspring. No familial differences have been detected in several previous studies using allozyme electrophoresis. This paper suggests that many polymorphic markers could be obtained with this species using the RAPD technique. Population genetic analysis of L. rubra has long been hampered by a dearth of polymorphic markers due to its small size. These findings suggest that this technique has the potential to further the study of population genetics in this asexual species.

Consequences of heat stress on reproduction of cattle

Heat stress represents one of the major environmental factors that adversely affect the reproductive performance of cattle. In this paper the behavioral adjustments, physical mechanisms and physiological responses to heat loss are described; bos indicus adaptive advantages with respect to bos Taurus, pathophysiology of heat stress and heat stress effects in animal reproduction, both the male and the female.

Abortion and Nation: The Politics of Reproduction in Contemporary Ireland

Abortion politics are contentious and divisive in many parts of the world, but nowhere more so than in Ireland. Abortion and Nation examines the connection between abortion politics and hegemonic struggles over national identity and the nation-state in the Irish Republic. Situating the abortion question in the global context of human rights politics, as well as international social movements, Lisa Smyth analyses the formation and transformation of abortion politics in Ireland from the early 1980s to the present day. She considers whether or not the shifting connections between morality, rights and nationhood promise a new era of gender equality in the context of nation-state citizenship.
The book provides a new sociological framework through which the significance of conflict over abortion and reproductive freedom is connected to conflict over national identity. It also offers a distinctive in-depth consideration of the connection between gender and nationhood, particularly in terms of its impact on women's status as citizens; within the nation-state; within the European Union; and as members of a global civil society.
