AbstractPhytoplankton is confronted with a variable assemblage of zooplankton grazers that create a strong selection pressure for traits that reduce mortality. Phytoplankton is, however, also challenged to remain suspended and to acquire sufficient resources for growth. Consequently, phytoplanktic organisms have evolved a variety of strategies to survive in a variable environment. An overview is presented of the various phytoplankton defense strategies, and costs and benefits of phytoplankton defenses with a zooming in on grazer-induced colony formation. The trade-off between phytoplankton com

Grazing resistance in plants, which can be defined as the ability to grow and reproduce under grazed conditions, is either associated to defoliation avoidance or tolerance. Clonal traits are often neglected when studying functional responses to grazing, despite frequent occurrence in grassland vegetation. We investigated whether clonal traits and response to defoliation were associated to increased grazing resistance. First, grazing resistance was estimated for eight clonal species using abundance patterns in a long-term field study. We then analysed its correlation with traits in undisturbed

Intermediate wheatgrass [Thinopyrum intermedium (Host) Barkw. & D.R. Dewey subsp. intermedium] is a productive, high-quality perennial forage that lacks persistence under grazing. A study was conducted to evaluate the effects of three grazing times on soil bulk density, soil pH, and soil organic C under intermediate wheatgrass. Treatment effects on the three soil attributes were negligible, implying grazing time did not negatively impact intermediate wheatgrass beyond a threshold whereby critical soil functions were impaired. Findings from this study are important in the context of sustain

The impacts of long-term grazing on compaction were assessed in mixed prairie and fescue grassland ecosystems of Alberta. Grazing regimes were of light to very heavy intensities, grazed early, late, and continuously during the growing season. Bulk density was measured with a surface moisture/density gauge and a combination moisture/density probe to 65 cm. Penetration resistance to 30 cm was measured with a cone penetrometer. Solonetzic soils were less sensitive to compaction under grazing than Chernozemic soils. Heavy intensity and/or early season grazing had greater impacts on compaction than

The sheet resistance of the sample decreases at beginning of annealing due to the recovery of defects and then increases due to the growth of larger and separated particles. The particle size of MoSi2 grows linearly proportional to the annealing time is due to interfacial reaction controlled growth kinetics.

Millions of people have been depending on commons such as forests, pastures, grazing lands, and fisheries to meet their basic needs for centuries. Because these commons are often left unrecognized, they face the threat of enclosure, which risks depriving peoples in the Global South from their most basic access to essential resources. Legal scholars are therefore called upon to rethink the prevailing system of global governance. Very little has been said about the role that international law could play in the empowerment of communities in the self-management of their resources and in the resistance against enclosure. It remains unclear to what extent international law can require states to recognize the commons as a democratic practice of its own and protect marginalized populations from enclosure and dispossession. This chapter asks the question as to whether international law can be rethought as part of the solution in saving the commons from enclosure.

Using the example of the town of Labin in Istria, I demonstrate how isolation, the so-called periphery, can also serve as an expression of resistance in a cultural niche. The collective Labin Art Express (L.A.E., initiated by Dean Zahtila, late Krešimir Farkaš, Graziano Kršić) is the initiator of the fundamental L.A.E. project Underground City XXI ‒ independent underground Labin cultural city as an alternative to the existing above-ground, heteronomous Labin, i.e. the creation of a real city 150 m below the earth’s surface ‒ in underground halls and tunnels, carved in solid rock, connecting Labin, Raša, Plomin and Rabac, with streets, bars, galleries, swimming pools, playgrounds for children, shops, restaurants, the Museum of Mining and Industry of Istria. Thereby we can compare Labin in terms of urbanity and anthropology with the town of Katowice, which in 2018 was selected to host the most significant UN Climate Change Conference, following the 2015 Paris Agreement. Katowice were chosen as one of Europe’s most polluted sites due to the exploitation of coal i.e. the transition of the aforementioned town from a mining and industrial site to a modern industrial, economical, technological and cultural centre.

The farm lies about two hours away from the Shack but only historic inches away in concept. In the Driftless region of southwest Wisconsin, it bears upon it some of the beautiful contoured crop swirls of Coon Valley, telltale marks of Leopold’s influence. New Forest Farm, started by Mark and Jen Shepard, is restoration agriculture in action. The farm asks the land to do what it is tailored by nature to do best and then trains it artfully, holistically, and prodigiously for personal, natural, and commercial use. From the sky, it looks like a child’s fingerpainting in green, with curlycues and waves of varying shades, dotted with treetop spheres, winding around ridges and swells. Lovely, biologically diverse, and drought resistant. It has pocket ponds with connective rain-irrigation swales cut into the contours following gradual lines of gravity to disperse captured moisture into the roots and soil for storage. In the face of the worst drought since 1933, this farm stood out lush and lively, though the chestnuts, hazelnuts, and fruit trees produced a reduced harvest, saving their energies for survival. On the spring day we visited, three new shaggy, fawn-colored Highland cattle had just arrived—a mother, son, and calf—along with some new solar-powered electric fencing for pasturing paddocks. “The animals get to know the whole thing,” says Peter Allen, the land manager in his early thirties who expounds on the sequential grazing of the cattle, pigs, sheep, chickens, and turkeys. “They stay for a day in the paddock, and they’re ready to move on to the next when we open the gates.” A PhD student from UW-Madison’s Nelson Institute for Environmental Studies, Allen is applying precepts of wildlife and land ecology to the emerging field of restoration agriculture. He’s also a warm host and knowledgeable tour guide, handing out exciting details like the intoxicating cider made here.

Streszczenie:

The general questions of root/shoot ratio, allocation of carbon to the root system, and root system dynamics are discussed in chapter 9, and the detailed root structure in chapter 5. Root-derived carbon forms the substrate for rhizosphere and symbiotic organisms, and hence leads to the increase in their population densities close to or in the root. Some of the carbon compounds from the root have specific chemical effects also (see chapter 7). Both quantity and composition of these materials need to be known if their effects are to be understood, and we discuss this subject here. The terminology of these materials is rather confused. The collective name for the injection of plant-derived carbon into the soil around living roots is ‘rhizodeposition’, but this has been used in different ways; for example, it may include root-respired carbon dioxide (Whipps 1990), but Darrah (1996) excludes carbon dioxide. The various forms include (Rovira et al. 1979; Lambers 1987; Whipps 1990) solid tissues lost from the root during growth; mucigel and debris from root surfaces and root cap; low-molecular-weight organic compounds in solution; carbon dioxide produced by root respiration for maintenance and for growth; faunal grazing of root tissues; and carbon transferred into symbionts, such as mycorrhizas and rhizobia. Some authors subdivide certain of these classes further. ‘Rhizodeposition’ is loss from a functioning root, but over a longer period the death and decomposition of whole roots deposits large quantities of carbon into the soil, which continues to act as a more resistant microbial substrate (see chapter 9). All of these materials ultimately are converted to carbon dioxide (except for material formed into stable soil organic matter) and this is difficult to separate from carbon dioxide produced directly by root respiration. The main issue here is how the various forms of deposition alter the ability of the living root system to absorb nutrients. We use the following terms for clarity, and because they relate to the practical means whereby these materials are quantified. As the rhizosphere situation is very dynamic, the results obtained will depend upon the timescale considered. (a) Exudates: soluble low-molecular-weight material that comes directly from the living root (microbial metabolites may be similar, but are excluded).

Streszczenie:

The long history of research at the Jornada Basin (through the Agricultural Research Service [ARS] since 1912, New Mexico State University in the late 1920s, and joined by the Long-Term Ecological Research [LTER] program in 1981) has provided a wealth of information on the dynamics of arid and semiarid ecosystems. However, gaps in our knowledge still remain. One of the most perplexing issues is the variation in ecosystem dynamics across landscapes. In this concluding chapter to this volume, we propose a new conceptual model of arid and semiarid landscapes that focuses explicitly on the processes and properties that generate spatial variation in ecosystem dynamics. We also describe how our framework leads to future research directions. Many studies have documented variable rates and patterns of shrub invasion at the Jornada as well as at other semiarid and arid regions of the world, including the Western United States, northern Mexico, southern Africa, South America, New Zealand, Australia, and China (York and Dick-Peddie 1969; Grover and Musick 1990; McPherson 1997; Scholes and Archer 1997; see also chapter 10). In some cases, shrub invasion occurred very rapidly: At the Jornada, areas dominated by perennial grasses decreased from 25% to < 7% from 1915 to 1998 with most of this conversion occurring prior to 1950 (Gibbens et al. 2005; Yao et al. 2002a). In other cases, shrub invasion occurred slowly, and sites were very resistant to invasion; for example, perennial grasses still dominate on 12 out of 57 research quadrats originally established in black grama (Bouteloua eropoda) grasslands in the early twentieth century (Yao et al. 2002b). Soil texture, grazing history, and precipitation patterns are insufficient to account for this variation in grass persistence through time (Yao et al. 2002a). It is equally perplexing that although many attempts to remediate these shrublands back to perennial grasses have led to failure, some methods worked well, albeit with long (> 50 year) time lags (Rango et al. 2002; see also chapter 14). Although variations in vegetation dynamics and shrub invasion are the most well known, other lesser known aspects of arid and semiarid systems have been found to be quite variable as well.
