SummaryNegative effects of poaching on seabird populations are not usually evaluated quantitatively when assessing seabird colony conservation status, nor are they generally considered a major concern. We demonstrate that poaching is still intense in the Canary Islands, and has negative consequences for the conservation of seabird colonies. We quantified the effects of poaching of Cory’s Shearwater fledglings on breeding success on different islands in the Canaries, comparing colonies that suffer from intense, medium, or no poaching. Poaching reduced the breeding success of affected colonies to almost a third, potentially causing the future extinction of the colony. Only colonies with intense wardening campaigns reached high values of reproductive success, showing that government surveillance in conjunction with volunteers from different NGOs is a very effective approach in reducing poaching. A population sensitivity analysis was also conducted to provide data on the factors that most affect the performance of the model. Although population growth and mean final population size varied with increases and decreases in mortality and carrying capacity, only harvesting resulted in a probability of 100% of extinction in 20–40 years. To promote seabird conservation in regions such as the Canary Islands, a core archipelago for seabird species in the Atlantic, poaching control should be elevated by society to a level of urgency, requiring dedicated funding and mobilisation of experts and volunteers to adequately address it through education, prevention and enforcement.

Abstract We used DNA fingerprinting to assess genetic structure of populations in Cory's Shearwater (Calonectris diomedea). We analyzed mates and parent-offspring relationships, as well as the amount and distribution of genetic variation within and among populations, from the level of subcolony to subspecies. We found no evidence of extrapair fertilization, confirming that the genetic breeding system matches the social system that has been observed in the species. Mates were closely related, and the level of genetic relatedness within populations was within the range usually found in inbred populations. In contrast to previous studies based on allozymes and mtDNA polymorphism, DNA fingerprinting using microsatellites revealed consistent levels of genetic differentiation among populations. However, analyzing the two subspecies separately revealed that the pattern of genetic variation among populations did not support the model of isolation by distance. Natal dispersal, as well as historic and/or demographic events, probably contributed to shape the genetic structure of populations in the species.

The Impact

The impact of the Information and Technology (IT) sector on the countries’ innovation development has been recognized as crucial in prior and recent research studies. Moreover, firms’ innovativeness affects positively countries’ economies. Nevertheless, the global economic crisis of the last decade constituted a significant barrier to the development of country economies and had a negative effect on firms’ performance. Specifically, the negative consequences of the global crisis became harder for Southern Europe Countries. More specifically the Greek economy was suffered by an extended period of crisis with harder consequences than those of other European countries. The main purpose of this study was to examine the financial performance of Greek IT firms in the early years of crisis. Our findings have been relevant to those of previous studies which observed negative effects of the financial recession on firms profitability.

Normalization Process

The negative effects of job loss on mental health have been thoroughly described in the literature. However, different fluctuations in mental health during the unemployment period have been noticed. We argue that a coping process takes place in this kind of situation. Therefore, in this study, we investigated the effect of the unemployment normalization process on mental health during various stages of unemployment. Participants ( N = 803) completed the General Health Questionaire-12 and the Unemployment Normalization Questionnaire. Results showed that a negative perception of unemployment had the greatest impact on mental health during the different phases of unemployment. Nevertheless, during the first year, having a positive perception counteracted these negative effects, and after 1 year, the unemployment norm took over the role of buffering against the negative effects on mental health. These results indicate that unemployment is still perceived as negative, but depending on the stage of unemployment, various coping strategies are used to buffer the negative consequences of unemployment.

Initial Target

The premise underlying the implementation of any intervention aimed at changing behavioral or other symptoms of Alzheimer's disease (AD) is that the change will be beneficial in some manner for the patient and the benefits will outweigh any negative consequences that may simultaneously result from the intervention. Consequently, the ultimate task of investigators studying the impact of proposed interventions is to identify and measure the benefit that stems from the intervention, as well as any negative effects. When interventions are intended to create organic changes, as is traditionally true with pharmacologic interventions, the identification of relevant outcomes is made relatively simple through indicators of organic functioning. However, when intended changes are behavioral, the identification of appropriate outcomes is far more complex. An individual's behavior ultimately has an impact on all the actors within his or her social setting, directly or indirectly. Furthermore, changes in an individual's behavior may have an impact on other persons in such a way that these secondary changes feed back to further influence the initial target individual. Hence, it is likely that the most appropriate study designs for assessing the impact of interventions aimed at behavioral problems will include multiple outcome measures for multiple actors.

Tourism Activity

The Arctic continues to attract more and more tourists. In some of the Arctic regions, tourism in general and cruise tourism in particular is becoming one of the fastest growing economic sectors. However, aside from the economic benefit, the Arctic tourism poses a certain threat to the sensitive environment of the Arctic, which currently experiences constantly increasing pressure from economic activity and climate change. Major negative consequences of tourism activity include the pollution of territories and water zones, worry of animals, direct destruction of flora and fauna, loss of the places of habitat due to infrastructure development, etc. The listed facts underline relevance of the selected topic of research, as well as the need for legal protection of the Arctic environment from negative effects caused by tourism. Analysis is conducted on the current situation in the area of Arctic tourism, as well as the questions of Russia’s Arctic policy pertaining to tourism activity. A brief overview is provided to the international legal regulation in this sphere. The author concludes on the insufficiency of legal regulation in the area of Arctic tourism, and gives recommendations on the improvement of Russian legislation. It is noted that tourism is one of the few types of activities in the Arctic that sparks interests of multiple countries, and in which the acceptance of universal standards seems possible.

Mammal Diversity

Pineapple crops reduce the size of forest fragments and generate pressure on biodiversity in the remnants. To determine potential negative effects of forest fragmentation we assessed diversity and composition of terrestrial mammals in forest patches on three farms under pineapple crops. We placedSherman and Tomahawk traps, footprints traps near water bodies, and made daily tracks to obtain traces and direct observation of mammals. We identified seven species of wild mammals, mostly omnivorous and under a least concern conservation status. The effect of cover type generated by the pineapple crops is consistent with mammal composition. Pineapple crops could enhance the most common wildlife problems, such as predator-prey relationships. Therefore, pineapple plantations, by causing fragmentation and lack of connectivity among forest patches, threaten extinction of mammals in some of their original range.
