Concerns about the impact of pet dogs and cats on native wildlife populations have shaped pet control legislation, despite there being scant research of their impact in urban areas. Using an online questionnaire, we obtained data from 662 Australian dog and cat owners who had observed their pets capture prey in the previous 6 months. Of the pets observed to catch prey, dogs caught a median of 2 mammals, 2 birds, 2 reptiles, and 3 amphibians, whereas cats caught a median of 3 mammals, 2 birds, 4 reptiles, and 2 amphibians. Of mammals caught by dogs and cats, 88 and 93%, respectively, were identifiable as introduced mice, rats, and rabbits. Of pets that caught prey, a substantial proportion caught native animals (62% of dogs and 47% of cats). However, median numbers of native animals caught per dog (2) or cat (3) over 6 months were low. Small skinks and lizards comprised the greatest proportion for dogs and cats, but dogs also caught larger native prey (e.g., possums, kangaroos, and wallabies). Most birds caught by dogs and cats were common or introduced (dogs: crested pigeons and lorikeets; cats: noisy miners and rosellas). To design measures that will effectively protect Australia's native wildlife, thorough understanding of the role dogs and cats play in Australian urban ecosystems is required. These findings can inform that understanding, and assist with development of management strategies for urban dogs and cats, and as well as directing resources to efforts that will most protect urban wildlife.

This paper aims at examining drought characteristics as an evidence of climate change in two agro-climatic zones of Nigeria and farmers' perceptions of impacts and adaptation strategies. The results show high spatial and temporal rainfall variability for the stations, in consequence, there are several anomalies in rainfall in recent years but much more in the locations around the Guinea savanna. The inter-station and seasonality statistics reveal less variable and wetter early growing seasons and late growing seasons in the Rainforest zone, and more variable and drier growing seasons in other stations. The probability (p) of dry spells exceeding 3, 5 and 10 consecutive days is very high with 0.62≤p≥0.8 in all the stations, though, the p-values for 10day spells drop below 0.6 in Ibadan and Osogbo. The results further show that rainfall is much more reliable from the month of May until July with the coefficient of variance for rainy days 0.30), though CV-RD appears higher in the month of August for all the stations. It is apparent that farmers' perceptions of drought fundamentally mirror climatic patterns from historical weather data. The study concludes that the adaptation facilities and equipment, hybrids of crops and animals are to be provided at a subsidized price by the government, for farmers to cope with the current condition of climate change.

Workplace ostracism is a prevalent and detrimental type of mistreatment. To curtail this harmful behavior, researchers need to identify who is more likely to intentionally ostracize others at work and the motives that drive them to do so. Past reviews of workplace ostracism focus primarily on the outcomes of ostracism, and the few that address the antecedents often examine a limited set of variables. We examined themes in the ostracism literature and determined that employees intentionally ostracize others due to either punitive or defensive motives. Punitive motives are focused on protecting the interests of the group, whereas defensive motives pertain to defending the interests of the self. We present a model of the ostracizer based on these motives and the associated perceptions of threat and negative emotions that precipitate ostracism. Our model provides an extension of the workplace ostracism literature by presenting a testable theoretical framework, rooted in appraisal theory, to explain why and when employees are likely to ostracize others at work. We also provided suggestions for an expansion of the ostracizer motives literature, with the goal of encouraging research that provides greater understanding of the perspective of the ostracizer.

While the Appalachian National Park Association was successful in gaining support from southern states to purchase land for a park or forest reserve, in order to do so, each state had to cede its authority to the federal government to acquire title to such lands. In January 1901, North Carolina passed a bill giving Congress that authority. By April 1901, South Carolina, Georgia, Alabama, Tennessee, and Virginia followed suit.
