This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern and southern flying squirrels are sympatric in Ontario due to climate change. In this area of range overlap hybridization occurs. I investigated potential species barriers in this recent hybrid zone. First I examined whether divergence in microhabitat use through time would lead to reinforcement of reproductive isolation. I found microhabitat variables to be weak predictors of trap-level species presence and found no evidence of divergence between species over 18 years. I also found latitude to be the strongest predictor of species occurrence across sites. Second, I tested whether parasite-mediated competition via the parasite, Strongyloides robustus, could maintain species barriers. I found a weak negative effect of S. robustus on northern flying squirrels, but I found a low parasite prevalence in southern flying squirrels compared to northern flying squirrels. Further, I found no evidence that presence of S. robustus would lead to competitive exclusion of northern flying squirrels from woodlots through apparent competition with southern flying squirrels. Therefore, divergence in microhabitat use and parasite-mediated competition do not appear to contribute to reproductive isolation of flying squirrels in Ontario.

Book Synopsis Relict Species by : Jan Christian Habel
Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
Book Synopsis Global Re-introduction Perspectives by : Pritpal S. Soorae
Download or read book Global Re-introduction Perspectives written by Pritpal S. Soorae and published by IUCN. This book was released on 2010 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is the second issue in the Global Re-introduction Perspectives series and has been produced in the same standardized format as the previous one. The case-studies are arranged in the following order: Introduction, Goals, Success Indicators, Project Summary, Major Difficulties Faced, Major Lessons Learned, Success of Project with reasons for success or failure. For this second issue we received a total of 72 case-studies compared to 62 in the last issue. These case studies cover the following taxa as follows: invertebrates (9), fish (6), amphibians (5), reptiles (7), birds (13), mammals (20) and plants (12) ... We hope the information presented in this book will provide a broad global perspective on challenges facing re-introduction projects trying to restore biodiversity."--Pritpal S. Soorae.

Book Synopsis The Call of Carnivores by : Prof. Hans Kruuk
Download or read book The Call of Carnivores written by Prof. Hans Kruuk and published by Pelagic Publishing Ltd. This book was released on 2019-03-11 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnivores include some of the most impressive, dangerous and mysterious animals in the world. Hans Kruuk has spent his life studying them against magnificent backdrops, from the Serengeti savannahs and Kalahari deserts to the Scottish Highlands, from the Galápagos Islands to the Far East. In each location he has used meticulous observation of animal behaviour to understand the ecology and natural history of wild carnivore populations, and ultimately to promote their conservation. This book describes the methods, challenges and rewards of the science of behavioural ecology. However, it essentially concerns the personal, rather than the scientific, side of that work, and above all the field experiences involved. With photographs and line drawings, it brings to life African safaris, the hyena in his bath, flights with vultures, dives with otters, attacks by a badger in Scotland and by feral dogs in Galápagos, gull-eating hedgehogs in Britain and the role of animals in African witchcraft. The author communicates his lifelong fascination with wildlife through these unique experiences and the insights they afforded him. Professor Kruuk is a leading authority on animal behaviour and the author of classic studies of hyaenas, otters and badgers, as well as a biography of his Oxford mentor Niko Tinbergen.
Book Synopsis Biology of Blood-Sucking Insects by : Mike Lehane
Download or read book Biology of Blood-Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
