Grebes
Grebes are specialized waterbirds which inhabit marshlands and reed-fringed lakes. Their dependence on wetlands is total and as a result they are particularly vulnerable to changes in ecosystems and their deterioration. So adapted are they to the wetlands they inhabit that they are an ideal indicator of the health of wetlands and the changes taking place, changes often imperceptible to humans. Since c. 1970, two of the 22 recognized species of grebes have gone extinct and two others are in a critical situation. One of the greatest threats to their survival is loss of habitat. This action plan reviews the threats to grebes throughout the world and their current status and proposes a series of eight priority actions to ensure their survival.
Grounds for Review
Garden Festivals are more than temporary horticultural expositions. Complex and phased, these projects have additional significance as planning stratagems, reclamation projects, public art venues, and precursors of new urban parks. Their scope extends well beyond that implied by the term ‘garden festival’. Typically exceeding 50 hectares, they stimulate development and steer site design through a unique merger of domestic garden culture with a large-scale urban project. A general discussion of the origins, formative elements and chronology of the generic event followed by cross-cultural reviews and analyses of numerous recent festivals and their site legacies form the core of this first ...
The Courage of Birds
From our own backyards to the rim of the Arctic ice, countless birds have adapted to meet the challenges of the winter season. This is their remarkable story, told by award-winning birder and acclaimed writer Pete Dunne, accompanied by illustrations from renowned artist and birder David Sibley. Despite the seasonal life-sapping cold, birds have evolved strategies that meet winter’s vicissitudes head on, driven by the imperative to make it to spring and pass down their genes to the next generation. The drama of winter and the resilience and adaptability of birds witnessed in the harsher months of the calendar is both fascinating and astonishing. In The Courage of Birds, Pete Dunne—winner ...
Land Condition Trend Analysis Avian Database: Ecological Guild-based Summaries
Land Condition Trend Analysis (LCTA) bird database documentation capabilities often are limited to the generation of installation-wide species checklists, estimates of relative abundance, and evidence of breeding activity. The conservation and characterization of biological diversity is becoming a management objective of both governmental and private organizations, and as such, more ecologically descriptive summaries are being required. Ecological guild analyses have been proposed as a means to link wildlife to a specific biodiversity component, and thus represents an option to military trainers in evaluating impacts to wildlife communities. This report documents an LCTA database update that...
In Need of Your Prayers and Patience
The Church of the Nazarene embraces American attachments to democratic rule, individual initiative, efficiency, and a strong sense of responsibility as "a city on a hill." It is also present in more than 150 world areas. These attributes are reflected in the astounding story of one of the founders of the denomination, H. F. Reynolds, who has been long hidden in the shadow of his early colleague, Phineas Bresee. While the church points to Bresee as its founding father, Reynolds lived and served for an additional two decades following Bresee's death, shaping the role of the General Superintendency, clarifying and expanding the church's Manual to meet the needs of the growing denomination, and establishing mission policies and practices that took it from a US church to a global presence. Reynolds maintained a lively devotion to Christ as he survived train wrecks, war, dread disease, and the sheer volume of meetings, correspondence, and explosive scandal that came with the nurturing of a new church. His vision and methods have profoundly influenced a denomination that does not know his name. This volume is designed to make the introduction.
Studies in Skin Perfusion Dynamics
This book talks about photoplethysmography (PPG) techniques based on computer-aided data processing. In particular, it presents the results of a co-operative Indo-German project on the topic between Indian Institute of Technology at Chennai and RWTH Aachen University. Measuring system design, experimental details and some preliminary results obtained so far within the framework of this project are presented here. From the investigations carried out so far using the PPG sensors in conjunction with breathing sensors, it has been possible to monitor the 0.125 to 0.15 Hz rhythms in the arterial volumetric changes and to study the influence of breathing on them. These rhythms, which according to ...
