Mismatch Hypothesis

Global warming is predicted to adversely affect the reproduction of birds, especially in northern latitudes. A recent study in Finland inferred that declining populations of black grouse, Tetrao tetrix , could be attributed to advancement of the time of mating and chicks hatching too early—supporting the mismatch hypothesis. Here, we examine the breeding success of sympatric capercaillie, T. urogallus, and black grouse over a 38-year period in southeast Norway. Breeding season temperatures increased, being most pronounced in April. Although the onset of spring advanced nearly three weeks, the peak of mating advanced only 4–5 days. In contrast to the result of the Finnish study, breeding success increased markedly in both species (capercaillie: 62%, black grouse: 38%). Both brood frequency and brood size increased during the study period, but significantly so only for brood frequency in capercaillie. Whereas the frequency of capercaillie broods was positively affected by rising temperatures, especially during the pre-hatching period, this was not the case in black grouse. Brood size, on the other hand, increased with increasing post-hatching temperatures in both species. Contrary to the prediction that global warming will adversely affect reproduction in boreal forest grouse, our study shows that breeding success was enhanced in warmer springs.

Comparative Survey

The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely ‘Reserva Biológica de Sooretama’ (REBIO Sooretama) and ‘Reserva Natural Vale’ (RNV), were surveyed for their orchid-bee faunas. Seventeen scent baits were used to attract orchid-bee males. Three-thousand, two hundred and twenty-five males belonging to 24 species were actively collected with insect nets during 100 hours in March, April and December, 2009. In comparison with a previous study in the same area twelve years before, it is evident that the abundance of all forest-dependent orchid bees analysed declined around 50%, and it was statistically significant (P = 0.022) for Euglossa marianae Nemésio, 2011, the most sensitive to anthropogenic disturbances of all Atlantic Forest orchid bees. On the other hand, the abundance of populations of species tolerant to open or disturbed areas rose. Possible explanations are discussed.

The 1960S

The TOPEX/POSEIDON satellite mission to observe the oceans triggered the formation of the new specialty of space oceanography from the 1970s to 1990s. Previously, in the 1960s in the United States, traditional oceanographers had shown little interest in the possibilities of space and thus space engineers and physicists worked on the first missions (Seasat in particular). TOPEX/POSEIDON brought together two projects, one American (TOPEX) and the other French (POSEIDON). The gradual crystallization of the disciplinary specialty of space oceanography occurred by making available a platform of instruments able to meet an ensemble of varied needs. Battery failures just before the launch of the joint mission meant that the mission had to focus on the essentials (notably El Niño effects). Subsequently, the discovery of a significant rise in sea levels due to global warming resulted in space oceanography becoming a recognized specialty. The case of TOPEX/POSEIDON shows the original ways in which instruments gained a place in the very large range of oceanographic techniques.

Nutritional Needs

Food insecurity is a recurrent condition in which members of a household do not have enough food to cover their nutritional needs; this condition contributes to increasing social vulnerability of those affected. In Peru, there are more than 9 million people who suffer this condition, which generates malnutrition and anemia, mostly in children. On the other hand, the waste of food is associated with production the large amounts of greenhouse gas emissions that affect global warming. According to reports in Peru, 20% of what is food produced becomes waste. This scenario in terms of food for Peruvians represents 3 billion calories in wasted food that could feed 2 million people. The Peruvian Food Bank manages food donations, ensuring this food can reach people in need through humanitarian aid entities. This applied research work uses the tools of operations research to determine a solution to the problem of maximizing the combination of food orders to be distributed based on their total nutritional value to the beneficiaries, seeking maximum coverage and minimum logistic costs.

This chapter scrutinizes the complex relationship between climate change and theology, as represented in First Reformed, as well as Paul Schrader’s understanding of humanity’s major problems today. Analyzing the issue of ecological decline through the prism of religion, Schrader outlines the ideology that presumably might help humanity survive at the age of global warming. Through the complex discussions of such issues as despair, anxiety, and hope, Schrader deduces the formula of survival in which preservation is the key component. Equating humans to God, Schrader, on the one hand, censures those actions that led to progress but destroyed the environment, yet, on the other hand, he foregrounds the fact that humans can also save the planet now. Schrader portrays both humans and Earth as living organisms created by God. He draws explicit parallels between the current state of our planet and the problems that we experience – from political ones, including war, to more personal ones like health issues.

Moral Duties

This chapter examines how we should think about ethics, starting with three framing questions: Do states and their citizens have significant moral duties to the members of other countries? Should states and their militaries be morally constrained in the conduct of war? Who is morally responsible for the alleviation of global poverty? The chapter proceeds by defining ethics and considering three significant and difficult ethical issues entailed by globalization: cosmopolitanism, statism, and realist ethics. It concludes by examining the ethical dimensions of global poverty and just war. Two case studies are presented, one dealing with the ethics of global warming and the other with the use of drones to carry out targeted assassinations. There is also an Opposing Opinions box that asks whether states should be morally free to reject as many immigrants, including refugees, as they choose.

Abstract Background Global warming is the most serious problem we face today. Each country is expected to ensure international cooperation toward minimizing risk. To evaluate the countermeasures, many researchers have developed integrated assessment models (IAMs). Then, how can each country achieve its emission quota? This study proposes models that analyze the economic impact of global warming in a region based on the results obtained by the global model. By using these suggested models, we perform a comparative analysis on three policy cases: a different regulations case, a unified regulation case, and an output redistribution case. Results We analyzed Japan as one of the case studies and found that more developed areas should implement stricter regulations in all scenarios. In addition, the case of applying different regulations by area (in a region) is not always preferable to using unified regulations in the region. Alternatively, the output gap between the output redistribution case and the different regulations case is much higher than the gap between the unified regulation case and the different regulations case. In all scenarios, the present values of the output of the output redistribution case are also higher than the other cases. Conclusions The different regulations case and the unified regulation case are based on the model without capital transfer between areas, whereas the output redistribution case is based on the model with free capital transfer between areas. Although both models are extreme situations, the regions close to the without capital transfer situation possibly have an incentive to use the different regulations policy, depending on the emission target. The regions close to the situation with free capital transfer would probably prefer unified regulation.

Breeding biology of the Coppersmith barbet, Megalaima haemacephala (Müller, 1776) was carried out between February, 2006 and January, 2007 at Sharawardy Uddyan, Ramna Park, Curzon Hall and National Botanical Garden. The breeding season started from December and ended in June. In total 20 nests were observed, of which 10 nests were studied in details in four study areas. The coppersmith barbet mostly preferred to make holes on the branches of koroi (Albizzia procera) for nesting. Egg laying started on 15th February in the study areas. Average height of nests from the ground was 9.7m and average depth and diameter of the holes was 29.20cm and 4.46cm respectively. New holes were constructed yearly or the old one was reused. Both the sexes took part in incubation of eggs, brooding and feeding to the nestlings. A total of 30 eggs were laid in 10 nests. Clutch size varied from 2 – 4 eggs (average: 3 eggs). Among them, 20 (66.67%) eggs were hatched and the rest 10 (33.33%) were unhatched and lost. Average incubation period was 14 days. The male and the female incubated the eggs for an average of 27.44 minutes/ hours and 32.56 minutes/ hours, respectively. Average number of nestlings (brood size) per nest was 2. Out of 20 nestlings, 16 left their nests successively. The breeding success was 53.33% in relation to the number of eggs laid and 80% in relation to nestlings hatched. The average weight of eggs and nestlings was 3.59g and 9.33g, respectively. The main causes of loss of the eggs and nestlings were human interference, predation and ectoparasitic infections. Insects and fruits were fed to the nestlings by their parents.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15397Univ. j. zool. Rajshahi Univ. Vol. 31, 2012 pp. 31-34

This paper is proposed to clarify the effectiveness of semantic expressions used to designate climate change in France context, i.e. “réchauffement climatique” (“global warming”); “changement climatique” (“climate change”); and “derangement climatique” (“climate imbalance”). An experimental study (sample size N = 126) based on ‘linguistic semantics’ approach is conducted in order to assess the effect of these expressions on concerns, perceptions risk and sensitivity regarding Climate Change (CC). Our results show that the expression “réchauffement climatique” (“global warming”) is the most appropriate from a statistical standpoint. It increased the importance of the problem (salience of this issue) relative to other societal issues (e.g. unemployment, social justice, crime, etc.); it also enhanced participants' sensitivity (respondents' emotions associated with CC) more than the other expressions. We can still note however a strong difference in impact among the expressions if we were to calculate their impact on the basis of risk perception and communication objective. Results showed that when focusing our communication campaigns on nature, it would be preferable to use the term “changement” ("change"), when focusing our communication on social level, it would be preferable to use the term “réchauffement” ("warming"), whereas the term “dérèglement” ("imbalance") becomes the most suitable in seeking to build a communication campaign focusing on economic aspects. Semantics therefore should be selected depending on the communication objective.

‘Arctic governance’ discusses how the Arctic, unlike many other parts of the world, has been spared military conflict, civil wars, and terrorism. Arctic governance involves an array of actors, legal regimes, institutional and social contexts, and strategic aspirations. In 1989, Finland approached the other seven Arctic states with a proposal for the Rovaniemi Meeting, which discusses the protection of the Arctic environment. This provided the foundation for the intergovernmental forum the Arctic Council (1996). The eight Arctic states will remain significant players in the future governance of the northern latitudes alongside indigenous peoples/permanent participants. There will always be powerful drivers that ensure that the 'global Arctic' will be prominent in multiple ways, including the role that China, the European Union, and other external states will play in shaping its future.

Abstract Acorn Woodpeckers (Melanerpes formicivorus) at Hastings Reservation in central coastal California exhibit a bimodal peak in annual breeding activity. One peak occurs in spring during which the majority of breeding takes place, while a second is centered in late August as the new acorn crop matures. These latter nests are mostly initiated in late summer but often do not fledge until at least late September and are thus referred to here as ‘fall’ nests. Fall nests occur in about one-third of all years, taking place when the acorn crop is large and summer temperatures are relatively high. Fledglings from fall nests constitute 4.3% of the population's total productivity and survive and recruit to the population at levels comparable to spring fledglings. Fall nesting is less likely in groups in which either the male or female breeding adults have undergone a change from the prior year, but groups are otherwise indistinguishable. Ecologically, fall nesting is closely tied to the acorn crop and thus to breeding success in the following, rather than the prior, spring. Among North American terrestrial birds in general, fall breeding has been reported in 16% of all species and is significantly more common among residents and colonially nesting species, in which the frequency exceeds 25%. Furthermore, fall nesting is likely to have been underreported in the literature. Thus, this phenomenon is at least an irregular part of the breeding biology of a substantial fraction of North American birds and should be considered a possibility in population studies of temperate-zone species. This is especially true given that fall nesting is likely to increase as global warming takes place.
