Seabird Ecology
In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics.
Marine Mammals and Noise
Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.
