African Birds is the perfect pocket-sized, folding guide for the bird lover and travelling nature enthusiast and highlights over 140 familiar species. Created and printed in the USA, this beautifully illustrated guide was updated in 2012 with a new cover design and a back panel map highlighting the country's eco-regions and prominent birding hotspots. Laminated for durability, this handy guide is a great source of portable information and ideal for field use by novices and experts alike.
Most of the Silver State is situated in the Great Basin, an arid plateau broken up by many short mountain ranges running from north to south. Nevada is the permanent or migratory home of 488 species of birds, including the state bird the beautiful mountain bluebird. This beautifully illustrated guide highlights over 140 familiar and unique species and includes an ecoregion map featuring prominent bird-viewing areas. Laminated for durability, this lightweight, pocket-sized folding guide is an excellent source of portable information and ideal for field use by visitors and residents alike. Made in the USA.
This book helps to establish a simple framework to identify and use bird species as bioindicator for high nature values (HNV) farmlands. HNV farming is present in all European countries, with a diversity of types and extensions. The need for measures to prevent the loss and monitoring in real time of the quality of HNV areas and to mitigate the loss of biodiversity is widely recognized, but requires urgent attention. One of the reasons is due to the deep differences between agro ecosystems of Central-Eastern and Western Europe, differences that can explain the lack of achievements of several conservation policies, and later also in practice. Some recent studies showed how agri-environmental measures adopted in the countries of European Community may be ineffective in order to guarantee the stop on biodiversity in some intensive farmland. However more studies focusing strategies to increase the effectiveness of agri-environmental measures for conservation are necessaries.
We focus our studies on suitable methods for monitoring the HNV areas, presenting the results of some case studies. This book proposes to integrate ecosystems assessment, geographical information systems (GIS) and strategies for conservation of local biodiversity. The proposed framework is focused on the use of species distribution models (SDMs) in order to explore the importance of each characteristic of HNV farmlands. Additionally, we examine the relationships among bird species richness, land use diversity and landscape metrics at a local scale in the farmlands.
An innovative framework is suggested to develop models, using the HNV farmlands as response variable and the presence or abundance of a set of few common bird species as covariates. Finally, by performing traditional SDMs on the bird species selected during the first step it becomes possible to study which characteristics of farmlands are driven the distribution of these species indicators. These results encourage the possibility to accurately identify the HNV farmland by the presence of just few common bird species, and then the possibility to monitor it with a cost-effective instrument, even linking lay people to programs based on citizen science.
