Download or read book The Tettigoniidae written by Winston J. Bailey and published by Springer. This book was released on 2012-12-14 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: by fireflies on calling heterospeciflcs (Lloyd 1984) or the location of calling crickets by tachiniid flies (Cade 197 5). Sexual selection theory would predict that if there were any risks involved in mating then the sex offering the highest investment should take fewer of them. Given these factors and an inherent risk of detection by predators of calling individuals, males are more likely to signal than females (Thornhi111979). Further, if the quantity (length and/ or loudness) of the acoustic signal were correlated with the risks of exposure, we may predict that insects calling from exposed perches, or in areas of high predation, would use calls with a low duty cycle (the calls are short and widely spaced in time). Belwood provides an extensive account of defensive strategies used . by tettigoniids in the tropical rainforests of Central and South America. Her discussion includes both cryptic strategies in avoiding day time predators and also signalling strategies avoiding those operating at night As the signal shortens so selection is transferred from the caller to the searching female, and male location may become more risky than calling itself. At this juncture it may be advantageous for the female to call in reply to the male. This role reversal in signalling often results in duetting where the male calls and the female replies within a very narrow time window. The male now searches for the female, taking on both risks of calling and moving.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest information on tropical tree physiology, making it a valuable research tool for a wide variety of researchers. It is also of general interest to ecologists (e.g. Ecological Society of America; > 3000 or 4000 members at annual meeting), physiologists (e.g. American Society of Plant Biologists; > 2,000 members at annual meeting), and tropical biologists (e.g. Association for Tropical Biology and Conservation, ATBC; > 500 members at annual meeting). (American Geophysical Union(AGU), > 20000 members at annual meeting). Since plant physiology is taught at every university that offers a life sciences, forestry or agricultural program, and physiology is a focus at research institutes and agencies worldwide, the book is a must-have for university and research institution libraries.

Download or read book Nature Strange and Beautiful written by Egbert Giles Leigh and published by Yale University Press. This book was released on 2019-08-20 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: A beautifully written exploration of how cooperation shaped life on earth, from its single-celled beginnings to complex human societies In this rich, wide-ranging, beautifully illustrated volume, Egbert Leigh explores the results of billions of years of evolution at work. Leigh, who has spent five decades on Panama’s Barro Colorado Island reflecting on the organization of various amazingly diverse tropical ecosystems, now shows how selection on “selfish genes” gives rise to complex modes of cooperation and interdependence. With the help of such artists as the celebrated nature photographer Christian Ziegler, natural history illustrator Deborah Miriam Kaspari, and Damond Kyllo, Leigh explains basic concepts of evolutionary biology, ranging from life’s single-celled beginnings to the complex societies humans have formed today. The book covers a range of topics, focusing on adaptation, competition, mutualism, heredity, natural selection, sexual selection, genetics, and language. Leigh’s reflections on evolution, competition, and cooperation show how the natural world becomes even more beautiful when viewed in the light of evolution.

Download or read book Pot Pollen in Stingless Bee Melittology written by Patricia Vit and published by Springer. This book was released on 2018-03-05 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers pot-pollen—the other product, besides honey, stored in cerumen pots by Meliponini. Critical assessment is given of stingless bee and pot-pollen biodiversity in the Americas, Africa, Asia and Oceania. Topics addressed include historical biogeography, cultural knowledge, bee foraging behavior, pollination, ecological interactions, health applications, microbiology, the natural history of bee nests, and chemical, bioactive and individual plant components in stored pollen. Pot-pollen maintains the livelihoods of stingless bees and provides many interesting biological products that are just now beginning to be understood. The Meliponini have developed particular nesting biologies, uses of building materials, and an architecture for pollen storage. Environmental windows provide optimal temperature and availability of pollen sources for success in plant pollination and pollen storage. Palynological composition and pollen taxonomy are used to assess stingless honey bee pollination services. Pollen processing with microorganisms in the nest modifies chemical composition and bioactivity, and confers nutraceutical benefits to the honey and pollen widely relished by native people. Humans have always used stingless bees. Yet, sustainable meliponiculture (stingless bee-keeping) projects have so far lacked a treatise on pot-pollen, which experts provide in this transdisciplinary, groundbreaking volume.
