Post-fire dynamics of the woody vegetation of a savanna forest (Cerradão) in the Cerrado-Amazon transition zone Acta Botanica
Reis,Simone Matias; Lenza,Eddie; Marimon,Beatriz Schwantes; Gomes,Letícia; Forsthofer,Mônica; Morandi,Paulo Sérgio; Marimon Junior,Ben Hur; Feldpausch,Ted R.; Elias,Fernando.
ABSTRACTFire can change the species composition, diversity, and structure of savanna vegetation, thus altering growth and mortality rates. Such changes in the woody vegetation of burned savanna forest were evaluated over four years in comparison to unburned savanna forest. All woody plants with a diameter at breast height > 10 cm were measured in 100 permanent plots. Six months later, 38 of these plots were burned. Three and a half years later, all surviving individuals were re-sampled. Species richness, diversity, and the number of individuals did not change in the burned plots, although they had significantly higher (p < 0.05) increases in basal area and mortality rates (5.1% year-1) than the unburned plots (3.0% year-1).Tachigali vulgarishad the...

Causes and Extent of Declines among Native North American Invertebrate Pollinators: Detection, Evidence, and Consequences Ecology and Society
Cane, James H; USDA-ARS; jcane@biology.usu.edu; Tepedino, Vincent J; USDA-ARS; andrena@biology.usu.edu.
Ecosystem health and agricultural wealth in North America depend on a particular invertebrate fauna to deliver pollination services. Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America's invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus...

Land abandonment, landscape, and biodiversity: questioning the restorative character of the forest transition in the Mediterranean Ecology and Society
Marull, Joan; Barcelona Institute of Regional and Metropolitan Studies (IERMB), Autonomous University of Barcelona; joan.marull@uab.cat; Tello, Enric; Department of Economic History and Institutions, Faculty of Economics and Business, University of Barcelona; tello@ub.edu; Diana, Giovanna L.; Barcelona Institute of Regional and Metropolitan Studies (IERMB), Autonomous University of Barcelona; gio.diana87@libero.it; Pons, Manel; Barcelona Institute of Regional and Metropolitan Studies (IERMB), Autonomous University of Barcelona; manel.pons.sanvidal@uab.cat; Coll, Francesc; Barcelona Institute of Regional and Metropolitan Studies (IERMB), Autonomous University of Barcelona; Francesc.Coll@uab.cat.
The effects of land abandonment on biodiversity have received considerable attention by scholars, but results are far from conclusive. Different cultural traditions of scientists seem to underlie the contrasting ways in which land abandonment is understood. Although the forest transition (FT) framework considers land abandonment as an opportunity for biodiversity conservation, European landscape ecologists characterize it as a threat. We use insights from both traditions to analyze the effects of land abandonment on landscape and biodiversity in a mountain area of metropolitan Barcelona. We do so through an in-depth historical case study covering a period of 160 years. A set of landscape metrics was applied to land-cover maps derived from cadastral...

The Value of Tropical Forest to Local Communities: Complications, Caveats, and Cautions Ecology and Society
Sheil, Douglas; CIFOR (Center for International Forestry Research); d.sheil@cgiar.org; Wunder, Sven; CIFOR (Center for International Forestry Research); S.Wunder@cgiar.org.
The methods used to value tropical forests have the potential to influence how policy makers and others perceive forest lands. A small number of valuation studies achieve real impact. These are generally succinct accounts supporting a specific perception. However, such reports risk being used to justify inappropriate actions. The end users of such results are rarely those who produced them, and misunderstanding of key details is a concern. One defense is to ensure that shortcomings and common pitfalls are better appreciated by the ultimate users. In this article, we aim to reduce such risks by discussing how valuation studies should be assessed and challenged by users. We consider two concise, high-profile valuation papers here, by Peters and colleagues...

Genesis of an indigenous social-ecological landscape in eastern Panama Ecology and Society
Sharma, Divya; Department of Biology, McGill University; divya.sharma2@mail.mcgill.ca; Vergara-Asenjo, Gerardo; Department of Biology, McGill University; Instituto Forestal de Chile; gevergara@gmail.com; Potvin, Catherine; Department of Biology, McGill University; Smithsonian Tropical Research Institute; catherine.potvin@mcgill.ca.
Knowledge of the interplay between ecological and social influences in the context of land-use decision-making is sparse. To help fill this gap, we conducted participatory land-cover mapping in an indigenous territory of eastern Panama to identify factors that influenced household land-use decisions. The map illustrated a mosaic of land cover dominated by pasture. Primary discourse on influences from 35 semistructured interviews with landowners, women, and youth emphasized economic concerns, such as subsistence, and social-cultural factors, such as reticence to abandon traditional agriculture. Multivariate analysis showed that timing of family settlement helped determine proportion of forest cover, and place of origin helped determine proportion of short...

The use of science-based tools for impact assessment has increasingly gained focus in addressing the complexity of interactions between environment, society, and economy. For integrated assessment of policies affecting land use, an analytical framework was developed. The aim of our work was to apply the analytical framework for specific scenario cases and in combination with quantitative and qualitative application methods. The analytical framework was tested for two cases involving the ex ante impact assessment of: (1) a European Common Agricultural Policy (CAP) financial reform scenario employing a modeling approach and combined with a comprehensive indicator analysis and valuation; and (2) a regional bioenergy policy scenario, employing a fully...

Landscape Patterns of Exurban Growth in the USA from 1980 to 2020 Ecology and Society
Theobald, David M; Colorado State University; davet@nrel.colostate.edu.
In the United States, citizens, policy makers, and natural resource managers alike have become concerned about urban sprawl, both locally and nationally. Most assessments of sprawl, or undesired growth patterns, have focused on quantifying land-use changes in urban and metropolitan areas. It is critical for ecologists to examine and improve understanding of land-use changes beyond the urban fringe&#8212;also called exurban sprawl&#8212;because of the extensive and widespread changes that are occurring, and which often are located adjacent to or nearby &#8220;protected&#8221; lands. The primary goal of this paper is to describe the development of a nationwide, fine-grained database of historical, current, and forecasted housing density,...

Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on three case study regions in the Swiss Alps and aimed to propose land-use practices and alternative policy solutions to ensure the provision of key EGS under climate and land-use changes. We summarized and synthesized the results of the project and provide insights into the ecological, socioeconomic, and political processes relevant for analyzing global change impacts on a European mountain region. In Mountland, an integrative approach was applied, combining methods from economics and the political and...

Trade-Offs between Ecosystem Services in a Mountain Region Ecology and Society
Briner, Simon; ETH Zurich, Agri-Food and Agri-Environmental Economics Group, Department of Environmental Systems Science; briners@ethz.ch; Huber, Robert; Swiss Federal Institute for Forest, Snow and Landscape Research WSL; robert.huber@wsl.ch; Bebi, Peter; WSL Institute for Snow and Avalanche Research SLF; bebi@slf.ch; Schmatz, Dirk R.; Swiss Federal Institute for Forest, Snow and Landscape Research WSL; dirk.schmatz@wsl.ch.
Mountain ecosystems provide a broad range of ecosystem services (ES). Trade-offs between different ES are an important aspect in the assessment of future sustainable land-use. Management of ES in mountain regions must confront the challenges of spatial and temporal heterogeneity, and interaction with structural changes in agriculture and forestry. Using a social-ecological modeling framework, we assess the relationships between forest and agricultural ES in a mountain region in Switzerland. Based on the concept of jointness in production, we evaluated trade-offs and synergies among food provision, biodiversity conservation, carbon sequestration, and protection against natural hazards. Results show that increasing the provision of a focal ES in a mountain...

Agricultural watersheds are affected by changes in climate, land use, agricultural practices, and human demand for energy, food, and water resources. In this context, we analyzed the agricultural, urbanizing Yahara watershed (size: 1345 km&#178;, population: 372,000) to assess its responses to multiple changing drivers. We measured recent trends in land use/cover and water quality of the watershed, spatial patterns of 10 ecosystem services, and spatial patterns and nestedness of governance. We developed scenarios for the future of the Yahara watershed by integrating trends and events from the global scenarios literature, perspectives of stakeholders, and models of biophysical drivers and ecosystem services. Four qualitative scenarios were created to...

Shorter Fallow Cycles Affect the Availability of Noncrop Plant Resources in a Shifting Cultivation System Ecology and Society
Dalle, Sarah Paule; Department of Plant Science, Macdonald Campus of McGill University; sarah.dalle@mail.mcgill.ca; de Blois, Sylvie; Department of Plant Science and McGill School of Environment, McGill University; sylvie.deblois@mcgill.ca.
Shifting cultivation systems, one of the most widely distributed forms of agriculture in the tropics, provide not only crops of cultural significance, but also medicinal, edible, ritual, fuel, and forage resources, which contribute to the livelihoods, health, and cultural identity of local people. In many regions across the globe, shifting cultivation systems are undergoing important changes, one of the most pervasive being a shortening of the fallow cycle. Although there has been much attention drawn to declines in crop yields in conjunction with reductions in fallow times, little if any research has focused on the dynamics of noncrop plant resources. In this paper, we use a data set of 26 fields of the same age, i.e., ~1.5 yr, but differing in the...

Globalization and Land-Use Transitions in Latin America Ecology and Society
Grau, H. Ricardo; Universidad Nacional de Tucuman; CONICET; chilograu@gmail.com; Aide, Mitchell; University of Puerto Rico; tmaide@yahoo.com.
Current socioeconomic drivers of land-use change associated with globalization are producing two contrasting land-use trends in Latin America. Increasing global food demand (particularly in Southeast Asia) accelerates deforestation in areas suitable for modern agriculture (e.g., soybean), severely threatening ecosystems, such as Amazonian rain forests, dry forests, and subtropical grasslands. Additionally, in the coming decades, demand for biofuels may become an emerging threat. In contrast, high yields in modern agricultural systems and rural&#8211;urban migration coupled with remittances promote the abandonment of marginal agricultural lands, thus favoring ecosystem recovery on mountains, deserts, and areas of poor soils, while improving human...

Conversions of natural ecosystems, e.g., from rain forests to managed plantations, result in significant changes in the hydrological cycle including periodic water scarcity. In Indonesia, large areas of forest were lost and extensive oil palm plantations were established over the last decades. We conducted a combined social and environmental study in a region of recent land-use change, the Jambi Province on Sumatra. The objective was to derive complementary lines of arguments to provide balanced insights into environmental perceptions and eco-hydrological processes accompanying land-use change. Interviews with villagers highlighted concerns regarding decreasing water levels in wells during dry periods and increasing fluctuations in stream flow between...

Accelerating environmental change is perhaps the greatest challenge for natural resource management; successful strategies need to be effective for decades to come. Our objective is to identify opportunities that new environmental conditions may provide for conservation, restoration, and resource use in a globally recognized biodiversity hotspot in southwestern Australia. We describe a variety of changes to key taxonomic groups and system-scale characteristics as a consequence of environmental change (climate and land use), and outline strategies for conserving and restoring important ecological and agricultural characteristics. Opportunities for conservation and economic adaptation are substantial because of gradients in rainfall, temperature, and land...

Long-Term Forest Dynamics and Land-Use Abandonment in the Mediterranean Mountains, Corsica, France Ecology and Society
Mouillot, Florent; DREAM CEFE/CNRS, France;.
Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents...

Habitat Fragmentation and Native Bees: a Premature Verdict? Ecology and Society
Cane, James H; USDA-ARS; jcane@biology.usu.edu.
Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find...

We examined how social-ecological factors in the land-change decision-making process influenced neighboring decisions and trajectories of alternative landscape ecologies. We decomposed individual landowner decisions to conserve or develop forests in the rapidly growing Charlotte, North Carolina, U.S. region, exposing and quantifying the effects of forest quality, and social and cultural dynamics. We tested the hypothesis that the intrinsic value of forest resources, e.g., cultural attachment to land, influence woodland owners&#8217; propensity to sell. Data were collected from a sample of urban, nonindustrial private forest (U-NIPF) owners using an individualized survey design that spatially matched land-owner responses to the ecological and timber...
