Conservative Management of Adenocarcinoma in Situ of the Cervix
Gynecologic Oncology, 2000The purpose of this study was to determine the method of treatment and outcome of women with cervical adenocarcinoma in situ (AIS).Following institutional review board approval, all women diagnosed with cervical AIS from 1987 to 1999 were identified. Data were retrospectively collected by record review and correspondence with medical providers.Of 132 ...

The Mediterranean Basin, especially the coastline and the semi-arid and arid rangelands, have in the recent past and are currently suffering acutely from human activities that result in genetic erosion. As discussed in earlier chapters, these activities include: increasing industrialization, pollution, urbanization, inadvertent fires, increasing ...

This chapter looks into ex situ conservation. It acknowledges that in situ conservation techniques might be needed if a successful ex situ conservation programme, which is termed reintroduction, is achieved. The chapter explores the subdivisions of ex situ conservation: intensive or general captive breeding programmes and gene banks.

In Situ and Ex Situ Conservation of Chinese Plants
2020In total, 28,385 higher plants were distributed in the nature reserves, accounting for 77.0% of the total number of higher plants in China. Among them, there are 3842 species which are effectively protected; 2478 species are better protected. More than 84.4% endangered species grow in national and/or provincial natural reserves.

This chapter focuses on ex situ (off-site) conservation, which is the protection and management of biodiversity in artificial, human-built environments. Indeed, ex situ conservation allows wild-caught individuals to be maintained under close human supervision in facilities like zoos, aquariums, botanical gardens, or arboretums.

Conservation and Change: A Comparison of In situ and Ex situ Conservation of Jala Maize Germplasm
Crop Science, 2006Conservation of agricultural genetic resources, whether in situ (in farmers' fields) or ex situ (in a germplasm repository), provides variation for breeding and selection efforts. In this study, we assayed levels of genetic diversity from in situ and ex situ populations of Jala, a very tall, large‐eared race of maize (Zea mays L. subsp. mays), using 22

Abstract: Detailed data are rarely available to show how interventions such as captive breeding programs can create an uncontrolled demand for live specimens of endangered species. We present a case study of the effect of a planned, internationally recognized captive breeding program on trade in the endangered ...

Ethiopian in situ conservation
2000The Ethiopian region is characterized by a wide range of agroclimatic conditions that account for the enormous diversity of its biological resources. Probably the most important of these is the country’s various crop plants that farmers have adapted over centuries of selection and maintenance under various agro-ecosystems. Ethiopia is often referred to
