Movement patterns were studied on a 1-ha isolated reef surrounding Arch Rock in southern Tasmania. Short-term movements were identified from diver observations, and interpretation of long-term movements involved multiple recaptures of tagged individuals. Visual observations indicated that the sex-changing labrids Notolabrus tetricus, Pictilabrus laticlavius and Pseudolabrus psittaculus were all site-attached, with females having overlapping home ranges and males being territorial. In the non-sex-changing labrid Notolabrus fucicola and in the monacanthids Penicipelta vittiger and Meuschenia australis, there was no evidence of territorial behaviour and 1-h movements were in excess of the scale of the study. The long-term results indicated that all species were permanent reef residents, with most individuals of all species except M. australis always being recaptured within a home range of 100 m × 25 m or less. Only 15% of individuals of M. australis were always recaptured within this range category. The natural habitat boundary of open sand between the Arch Rock reef and adjacent reefs appeared to be an effective deterrent to emigration. The use of natural boundaries should be an important consideration in the design of marine reserves where the aim is to minimize the loss of protected species to adjacent fished areas.

AbstractGuinea-Bissau is host to the westernmost subpopulation of the common hippopotamus Hippopotamus amphibius, which is one of only two known populations inhabiting coastal waters. The presence of hippopotamuses causes conflict with rice farmers as a result of crop damage and the absence of effective measures to protect crops. To develop an effective method for protecting rice fields, we studied the patterns of access to flooded and rain-fed rice fields by hippopotamuses and assessed the effect of the installation of electric fences. Hippopotamuses were detected in 54% of the flooded fields (n = 100) and in 31.9% of the rain-fed fields (n = 91). They were detected more frequently in fields on offshore islands than on the mainland, in unfenced than in fenced fields, and in fields closer to running water. Hippopotamuses entered fenced flooded fields less frequently than unfenced, and were detected most frequently at the end of the rainy season and the start of the dry season, and in the period of vegetative stem growth. Electric fences were an effective deterrent and facilitated increased rice production. The maintenance and cost of the electric fencing were acceptable to farmers, and therefore the use of such fencing is recommended to resolve the conflict between hippopotamuses and farmers in Guinea-Bissau and in other areas with similar conditions.

Gender-based violence (GBV) has grown into a pandemic. It has spread its tentacles so far and wide that no country or community in the 21st century is immune from it. There are, of course, laws to prevent GBV and punish the perpetrators of GBV. But, the laws, in general, pathetically fail to yield the desired result and fail to play the role of an effective deterrent as lawmakers themselves, most often, become lawbreakers. It is well known that patriarchy has a vested interest in gender inequality, which is the root cause of GBV. The dominant gender, male, uses violence against all other genders, including female and third gender, as a lethal weapon to prove their muscle-power, pseudo-superiority, and enjoy what is not morally and ethically and legally right. GBV is undoubtedly a human right violation. However, in the land of nonviolence, India, marital rape, among others, is still legal. Things are slowly changing, and it gives hope.

This chapter examines threats and responses to threats as they play themselves out in human interactions. One of the significant topics here is crime and punishment—notably, how criminal statutes seek to prevent crime by threatening criminals with punishment sufficient to provide an effective deterrent. There is a long and fascinating history of such efforts, with very little success. This leads to a look at the death penalty in particular and whether it has been effective in preventing capital crimes. The chapter also assesses how people turn to religion when under threat, as well as how religions have often threatened their adherents with after-death retribution for sin, which has long influenced much human anxiety and, in some cases, compliance. Moreover, the chapter reflects on the menace of death plus threats involved in the American gun culture, and race-based and economic anxieties driving the rise of right-wing national populism.

That military expenditure and conflict have adverse consequences for development is unsurprising but important. The policy challenge is to reduce them. I have suggested that substantial components of military expenditure could be reduced without jeopardizing security interests. Military expenditure does not appear to be an effective deterrent of rebellion, and, if it is reduced in a coordinated manner across a region then external security interests would be unaffected. The resources released by reduced military expenditure could be used to increase growth rates, and this in turn would gradually but effectively reduce the risk of internal conflict. Development, not military deterrence, is the best strategy for a safer society.

Background In northern European and North American cities geese are one of the commonest and most visible large herbivores that inhabit the suburban environment . As such, their presence and behavior often conflicts with the desires of the human residents. Fouling, noise, aggression and health concerns are all cited as reasons that there are “too many”. Lethal control is often used for control, however, this raises questions about whether this is a sustainable strategy to resolve the conflict between humans and geese, when paradoxically, it is humans that are responsible for creating the habitat and often providing the food and protection of geese at other times. We hypothesis that the landscaping of suburban parks can be improved to decrease its attractiveness to geese and to reduce the opportunity for conflict between geese and humans. Methods. Using observations collected over five years from a botanic garden situated in suburban Belgium and data from the whole of Flanders in Belgium we examine landscape features that attract geese, including the presence of islands in lakes, the distance from water, barriers to level flight and the size of grazing areas. The birds studied were the tadornine goose Alopochen aegyptiaca (L. 1766) (Egyptian geese) and the anserine geese, Branta canadensis (L. 1758) (Canada geese), Anser anser (L. 1758) (greylag geese) and Branta leucopsis (Bechstein, 1803) (barnacle geese). Landscape modification is a known method for modifying geese behavior, but there is little information on the power of such methods with which to inform managers and planners. Results. Our results demonstrate that lakes with islands attract more than twice as many anserine geese, than lakes without island, but make little difference to Egyptian geese. Furthermore, flight barriers between grazing areas and lakes are an effective deterrent to geese using an area for feeding. Keeping grazing areas small and surrounded by trees reduces their attractiveness to geese. Conclusion. The results suggest that landscape design can be used successfully to reduce the number of geese and their conflict with humans. However, this approach has its limitations and would require humans to compromise on what they expect from their landscaped parks, such as open vistas, lakes and closely cropped lawns.
