Synthesis
Cranes have a close relationship with arable and pastoral agriculture that goes back hundreds, presumably thousands of years. The landscapes and ecoregions important to cranes are also those areas most conducive to agriculture. Thus, cranes and humans are attracted to the same landscapes and will therefore have futures that remain co-mingled. As such, agriculture can both benefit and inhibit crane

Threats to cranes related to agriculture
The greatest threats to cranes worldwide are related to agricultural activities. They include direct losses of wetlands or grasslands; altered wetland hydrology due to water control systems such as dams or irrigation ditches; fire; direct and indirect impacts from agricultural chemicals; human disturbances; disease risks where cranes congregate in high densities on crops or in association with dom

Methods to reduce conflicts between cranes and farmers
Alternative methods to reduce conflicts between cranes and farmers range from relatively simple, inexpensive disturbance methods to changes in land use at a landscape scale. Visual and acoustics disturbance methods can be useful for small fields or gardens but require frequent changes to prevent habituation by the cranes. Changes in farming practices can be implemented by individual farmers and ma

Interactions and impacts of domesticated animals on cranes in agriculture
Affiliations of most cranes to humans and agriculture means they often interact with a variety of domestic animals. Those interactions can be beneficial or neutral when domestic animal densities and their impact on wetland or grassland systems are low to moderate, as found in more traditional agricultural practices. The most common interaction is with grazers, primarily domestic ungulates such as

Observed climate change
As discussed in Chapter 1, climate is one of the principal factors that have determined the composition and extent of forest ecosystems in the Mid-Atlantic region during the past several thousand years. This chapter describes the climate trends in the assessment area that have been observed during the past century, including documented patterns of climate-related processes and extreme weather even

The San Andreas Fault System--Complexities along a major transform fault system and relation to earthquake hazards
The San Andreas Fault System is a 1300-km-long transform boundary that accommodates motion between the North American and Pacific Plates. New technologies and data reveal rich details about the present configuration of faults, distribution of strain and associated seismic hazard on this complex network of faults. This contribution provides a brief summary of the geologic history of the San Andre

Shorebirds adjust spring arrival schedules with variable environmental conditions: Four decades of assessment on the Yukon–Kuskokwim Delta, Alaska
Arctic summers are brief, and there has been strong selection for migratory birds to
arrive in Arctic nesting areas as early as possible to time breeding with peak food availability
and complete reproduction. The timing of emergence of nesting habitat in spring is, however,
extremely variable in the Arctic, and few long-term studies have examined the ability of avian
migrants to track spring condi

Large hydromagmatic eruption related to Fernandina Volcano’s 1968 caldera collapse—Deposits, landforms, and ecosystem recovery
The hydromagmatic eruption that immediately preceded the 1968 caldera collapse of Fernandina Volcano, Galápagos, which had a volcano explosivity index (VEI) of 4, offers a case study of powerful eruptions where basaltic magma interacts with caldera-ponded water. The 4-d-long hydromagmatic eruption sequence records an early stage and a small fraction of the volume of magmatic withdrawal that led th

Health and disease treatment in captive and reintroduced Whooping Cranes
The principles and applications of medicine in Whooping Cranes (Grus americana) are similar to that for other crane species, though the necessity of managing Whooping Crane health across the captive, reintroduced, and remnant populations poses particular challenges. In this chapter, we review the important aspects of crane medicine relevant to managing Whooping Cranes in captive and reintroduced e
