To engage people in biodiversity and other environmental issues, one must provide the opportunity for enhanced understanding that empowers individuals to make choices and take action based on sound science and reliable recommendations. To this end, we must acknowledge some real challenges. Recent surveys show that, despite growing public concern, environmental issues still rank below many other...

and illegitimate babies and, in some countries, to serious overpopulation. Susser and Watson's book deals with many of these problems and contrasts the health experiences of peasant and industrial populations and in different social classes. The second edition has been enlarged by about one third due to the addition of material from the American experience of the authors and by the addition of ...

Pet overpopulation is a problem for humans not only because of the increased rabies exposure risk but also because it puts a strain on animal control agencies, which must care for, house, and often euthanize the unwanted animals. New Hanover County, North Carolina, Animal Control Services saw the need to control this problem and developed a plan to diminish the number of unwanted companion anim...

Condition factor, gonadosomatic index, sex ratio and length weight relationship of Mormyrus rume, Mormyrus hasselquisti, Gnothonemus cyprinoides, Gnathonemus senegalensis and Petrocephalus bane ansorgei (Mormyridae) from Asa Lake, Ilorin, Nigeria were studied. The results showed that the condition factor range were 0.57-1.12, 0.64-1.22, 0.46-0.98, 0.66-1.18 and 0.86-1.28 in G. senegalensis, G. ...

T are an estimated 60 to 100 million feral and abandoned cats in the United States. By any measure, this is an important welfare issue, and the many bodies of free-roaming cats visible along roadsides across the country are mute testimony to the tragedy of their unhappy lives. Many people of goodwill want to see this situation improved. Some believe that feeding feral cats; trapping, neutering,...

Early-age neutering of puppies and kittens (as early as 6-7 weeks of age) is increasing in popularity in the United States. This increase likely results from accumulating information on the safety of the procedure and lack of long-term adverse side effects. As veterinarians become comfortable and familiar with the procedure, they are likely to encourage more clients to consider early-age neuter...

Fitness sharing is a popular diversity mechanism implementing the idea that similar individuals in the population have to share resources and thus, share their fitnesses. Previous runtime analyses of fitness sharing studied a variant where selection was based on populations instead of individuals. We use runtime analysis to highlight the benefits and dangers of the original fitness sharing mech...

The interaction of man with viral agents was possibly a key factor shaping human evolution, culture and civilization from its outset. Evidence of the effect of disease, since the early stages of human speciation, through pre-historical times to the present suggest that the types of viruses associated with man changed in time. As human populations progressed technologically, they grew in numbers...

Since the 1940s, perceived companion animal overpopulation in the United States has been an important issue to the animal welfare community (Moulton, Wright, & Rinky, 1991). This surplus of animals has resulted in millions of dogs and cats being euthanized annually in animal shelters across the country. The nature and scope of this problem have been notoriously difficult to characterize. The nu...
