Endocrine Disrupting

At the onset of the industrial age, environmental contaminants began to pose a major threat to the health of wildlife. That threat appears to continue today. In the last three decades, the focus of our concern on the health consequences of environmental pollution has been on lethal, carcinogenic, and/or extreme teratogenic manifestations. Evidence from a number of sources suggests that another mechanism, endocrine-disruption, also must be examined. There is excellent laboratory and field evidence that man-made chemicals (xenochemicals) released into the environment act as hormones or antihormones. They act as endocrine-disrupting contaminants (EDCs). The release of EDCs occurred in the past and continues today. The development of the reproductive system is vulnerable to perturbation by EDCs. Wildlife studies demonstrate that both sexes are affected and experience modifications of gonadal and reproductive tract development or functioning and abnormal synthesis or metabolism of hormones. A number of abnormalities seen in the reproductive system of various wildlife species correlate with similar abnormalities described as rising in human populations. We suggest that wildlife are excellent sentinels of ecosystem health. Data from these wildlife studies present models and methodologies for examining human health.

<em>Abstract.</em>—Wood in rivers, or wood deposited from fluvial processes, provides unique habitat for terrestrial and aquatic wildlife species. Many wildlife species utilize riparian areas for some portion of their life history primarily due to the universal need for water, the presence of unique plant assemblages, and the diversity of microhabitats produced by the dynamics of river systems. Wood in rivers provides four primary functions for aquatic and terrestrial wildlife species: habitat structure, shelter, patchiness of habitat, and increased food resources. Abundance and diversity of wildlife species are enhanced by wood in rivers, and they, in turn, shape and maintain aquatic and riparian habitats. Though there is a clear link between wood in rivers and riparian wildlife communities, knowledge about their interactions and interdependence is sparse.

In the histologic and electron microscopic study of the male reproductive system of bullfrog, Rana catesbeiana, a vesicular system associated with spermiogenesis was observed. It appeared in the lumenal space of the seminiferous tubule (Fig. 1), in the heads of spermatids (Fig. 2), associated with the chromatins of the spermatid (Fig. 4). As deduced from sections, this vesicular system consisted of vesicles of various size or a large group of waving and twisted tubules (Fig. 3), After routine procedure of treatment for electron microscopy, the lumens of both of the vesicles and tubules were electron lucent.In human, vesicles and vesicular system associated with reproductive cell and tissue were reported. In abnormal spermiogenesis, flower-like body, actually vesicles, and giant vesicle associated with the head of spermatid were observed. In both cases the number of vesicle was limited from a single one to a few.

General Guidance

The Worker Protection Standard (WPS) is a Federal regulation designed to protect agricultural workers (people involved in the production of agricultural plants) and pesticide handlers (people mixing, loading, or applying pesticides or doing other tasks involving direct contact with pesticides). It has been in full implementation since 1995. This document provides general guidance to help you comply with the requirements of the Federal Worker Protection Standard (WPS) for agricultural pesticides, 40 CFR part 170, as amended in 2015. This document addresses specific information that agricultural establishments must display at a central location for their employees.

Animal Habitat

Animals in Florida provide a variety of benefits to people, from recreation (fishing, hunting, or wildlife viewing) to protection of human life and property (oysters and corals provide reef structures that help protect coasts from erosion and flooding). By measuring the economic value of these benefits, we can assign a monetary value to the habitats that sustain these species and assess the value that is lost when development or other human-based activities degrade animal habitat. This 5-page fact sheet presents the results of a study that assessed the value of protecting five animal species in Florida and showed the economic value of protecting animal habitat.
