Carnivore predation on livestock often leads people to retaliate. Persecution by humans has contributed strongly to global endangerment of carnivores. Preventing livestock losses would help to achieve three goals common to many human societies: preserve nature, protect animal welfare, and safeguard human livelihoods. Between 2016 and 2018, four independent reviews...
The problem of extinction in the sea has been recognized
only recently by the scientific community (Roberts and
Hawkins 1999). For the last decade, the American Fisheries
Society (AFS) has pursued an initiative to identify marine
fish stocks that may be at risk of extinction in North America
(Musick 1998;...
In February of 1975, the School of Forestry sponsored a series of lectures and discussions on the topic, "Forests of the World-Future Resources Conflicts." The objectives of these presentations were to examine prospects for future forest use, the demands that will be made on forest resources of all sorts, the...
Basaltic volcanism provides a window into the Earth’s mantle. Seeing through this window requires seeing through the processes of magma genesis and evolution that distort the view. Radiogenic isotope ratios, and to a lesser extent incompatible elements and stable isotope ratios, allow us to see through these distortions and infer...
When the Bolsheviks came to power in Russia in 1917, party leaders under-stood well that a thorough social transformation lay between them and the full realization of long-term revolutionary objectives. The seizure of political authority and even a proposed redistribution of economic goods and services would not themselves create citizens...
Along the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) have caused losses to natural resources and coastal economies, and have resulted in human sicknesses and deaths for decades. Recent reports indicate a possible increase in their prevalence and impacts of these events on living...
Anthropogenic impacts are increasingly affecting the world’s oceans. Networks of marine protected areas (MPAs) provide an
option for increasing the ecological and economic benefits often provided by single MPAs. It is vital to empirically assess the
effects of MPA networks and to prioritize the monitoring data necessary to explain those...
Disasters result from hazards affecting vulnerable people. Most disasters research by anthropologists focuses on vulnerability; this article focuses on natural hazards. We use the case of wildfire mitigation on United States Forest Service lands in the northwestern United States to examine social, political, and economic variables at multiple scales that...
Increasingly, objectives for forests with moderate- or mixed-severity fire regimes are to restore successionally diverse landscapes that are resistant and resilient to current and future stressors. Maintaining native species and characteristic processes requires this successional diversity, but methods to achieve it are poorly explained in the literature. In the Inland...
Disease predictive systems are intended to be management aids. With a few exceptions, these systems typically do not have direct sustained use by growers. Rather, their impact is mostly pedagogic and indirect, improving recommendations from farm advisers and shaping management concepts. The degree to which a system is consulted depends...
Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences. Evapotranspiration was higher than was predicted by temperature in water-surplus ecosystems and lower...
Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...
According to the “social intelligence hypothesis,” species with complex social interactions have
more sophisticated communication systems. Giant otters (Pteronura brasiliensis) live in groups
with complex social interactions. It is likely that the vocal communication of giant otters is more
sophisticated than previous studies suggest. The objectives of the current study...
Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...
It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...
Crystallographic studies of ligands bound to biological macromolecules (proteins and nucleic acids) represent an important source of information concerning drug-target interactions, providing atomic level insights into the physical chemistry of complex formation between macromolecules and ligands. Of the more than 115,000 entries extant in the Protein Data Bank (PDB) archive,...
The life cycles of three Madden–Julian oscillation (MJO) events were observed over the Indian Ocean as part of the Dynamics of the MJO (DYNAMO) experiment. During November 2011 near 0°, 80°E, the site of the research vessel Roger Revelle, the authors observed intense multiscale interactions within an MJO convective envelope,...
Estimates of species' vital rates and an understanding of the factors affecting those parameters over time and space can provide crucial information for management and conservation. We used mark–recapture, reproductive output, and territory occupancy data collected during 1985–2013 to evaluate population processes of Northern Spotted Owls (Strix occidentalis caurina) in...
Long-term research on freshwater ecosystems provides insights that can be difficult to obtain from other approaches. Widespread monitoring of ecologically relevant water-quality parameters spanning decades can facilitate important tests of ecological principles. Unique long-term data sets and analytical tools are increasingly available, allowing for powerful and synthetic analyses across sites....
One of the important ‘hallmarks’ of cancer is angiogenesis, which is the process of formation of new blood vessels that are necessary for tumor expansion, invasion and metastasis. Under normal physiological conditions, angiogenesis is well balanced and controlled by endogenous proangiogenic factors and antiangiogenic factors. However, factors produced by cancer...
This study shows how patronage framed and fashioned the careers of Thomas Hobbes and
his patron William Cavendish, the earl of Newcastle. Newcastle's protection allowed
Hobbes to articulate heterodox ideas without immediate fear of reprisal. It also enabled
him to solidify his status as a gentleman and the intellectual equal...
The endangered western stock of the Steller sea lion (Eumetopias jubatus) - the largest of the eared seals - has declined by 80% from population levels encountered four decades ago. Current overall trends from the Gulf of Alaska to the Aleutian Islands appear neutral with strong regional heterogeneities. A published...

In the following pages the information, so far as it has been possible to obtain it, is given in the following order for each alumnus: Name, year in which the degree was conferred, degree, course, present occupation, and present mailing address.
Historians and sociologists of science often identify the efflorescence of social stud ies of science with the work of postwar American intellectuals such as Robert K. Merton and Thomas S. Kuhn. They often also refer to the views of Michael Polanyi (1891-1976) on the roles of tacit knowledge, apprenticeship, social...
Social media platforms are effective tools used
to help communicate and increase involvement in cultural, political,

Football today, most conspicuously at the professional level (National Football
League) is the economic and cultural colossus of American spectator sports. To
speak of its “life cycle,” then, would seem nonsensical: although it has a clear
“birth,” to speak of its “death” might seem ridiculously premature. Yet recent
developments make...

Visual appeal of wood is as important as its
structural integrity in outdoor applications. Discoloration
and checking of wood favor the utilization of alternative
materials for outdoor cladding and decking. Lignin depolymerization
is one of the critical processes leading to
weathering. In the present paper, the potential of different
classes...
Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. This publication provides a description and information on biology,...
Louis de Broglie received the Nobel Prize in Physics in 1929 following experimental
