Описание: Suriname has a long history of faunal inventories, with many of its species already described by Linnaeus. Despite that, the amphibians were only treated in a few papers in scientific journals. "Amphibians of Suriname" is the first overview of our present knowledge of this interesting group for Suriname. The book presents short descriptions and data on the distribution and natural history of the 104 species now known for the country. Most species are illustrated by one or more photographs, and a distribution map is presented as well. Two new species and two new subspecies of frogs are described for Suriname, and for several species a contribution to the taxonomic discussion is given.

Описание: Suriname, located on the Atlantic coast of northeastern South America, is a relatively small country compared to most other South American countries. It nevertheless has a rich avifauna. By the end of 2017, 751 species (including 765 subspecies) were known to occur in Suriname. Most of the land area of Suriname is still covered with tropical rainforest and the country should be a must-visit for birdwatchers. Suriname is even mentioned as being the best country to spot certain neotropical species. Surprisingly, few birders visit Suriname. The main reason given is the lack of a handy pocket guide that can easily be carried in a backpack. This (revised and updated) edition of the Field Guide to the Birds of Suriname (with its 109 color plates) tries to fill this gap. In addition to species accounts, data on topography, climate, geology, geomorphology, biogeography, avifauna composition, conservation, and hotspots for bird watching are given. So, why delay your trip to this beautiful and friendly country any longer? Suriname with its rich avifauna awaits you!

Описание: Since the limnological research on the man-made Brokopondo Reservoir in the 1960s, numerous data has been collected on the ecology of Surinam rivers and swamps. This book is a compilation of this data; it is a survey of the aquatic ecology of one of the peripheral areas of Amazonia.

Описание: Amphibians: Biology, Ecology and Conservation opens with a review of the current knowledge on the Harderian gland of anuran amphibians. The Harderian gland is an orbital gland present in all vertebrates possessing nictitating membrane, with the primordium of the Harderian gland appearing during metamorphosis throughout the development of the nictitating membrane. The authors go on to discuss D-Aspartate (D-Asp), an excitatory amino acid involved in the synthesis of sex steroid hormones. High concentrations of D-Asp were found in the gonads, in the brain and in the Harderian gland of the green frog, Pelophylax esculentus. The current knowledge on the D-Asp in gonads and in tissues during the seasonal reproductive cycle is reviewed. Since D-Asp modulates sex hormone synthesis, this book correlates the local amino acid levels with serum and local sex hormone concentrations. Next, the authors report on the existing work on the steroidogenic pathways activated in reproductive and post-reproductive phases in both testis and brain in the aforementioned green frog. Plasma testosterone levels are low in the non-breeding period and high during the breeding period, while 17β-estradiol levels illustrate a contradictory trend. This study indicates a close correlation between steroidogenic process in the testis and in the brain, suggesting a synergic mechanism of regulation. The concluding chapter presents three case studies that demonstrate how the life cycle of the giant toad, Rhinella marina, as well as its somatic and hepatosomatic index, voracious appetite and highly permeable skin make it a species susceptible to the bioaccumulation of organic and inorganic pollutants and their toxicological effects. Due to these characteristics, R. marina is considered to be a good biomonitor of environmental pollution.
