Responses of Emergent Marsh Wetlands in Upstate New York to Variations in Urban Typology Ecology and Society
Kleppel, G. S.; Department of Biological Sciences, University at Albany, SUNY; gkleppel@csc.albany.edu; Madewell, Shirley A; Department of Biological Sciences, University at Albany, SUNY; madewell@mail.com; Hazzard, Sarah E; Department of Biological Sciences, University at Albany, SUNY; hazzads@ecostudies.org.
Although it has been repeatedly demonstrated that urbanization has negative environmental consequences, the conversion of land to urban use is increasing worldwide and is not likely to abate. We tested the hypothesis that different urban typologies, i.e., distributions of human population and infrastructure, differentially influence the water quality and ecological functionality of emergent marsh wetlands in New York State's Hudson River Valley. Wetlands were studied in two watersheds, defined as landscapes bounded by ridge lines, containing traditional small-town development and two watersheds containing suburban typologies. Land cover attributes were evaluated by analyzing ground-truthed, orthophotoquad data with a GIS. Water quality, the cover and...

This paper outlines the qualitative components (the storylines) of the Millennium Ecosystem Assessment (MA) scenarios. Drawing on a mixture of expert knowledge, experience, and published literature, we have explored plausible consequences of four trajectories for human development. The storylines have been designed to draw out both benefits and risks for ecosystems and human well-being in all four trajectories with enough richness of detail to allow readers to immerse themselves in the world of the scenario. Only a summarized version of the storylines is presented here; readers are encouraged to read the more detailed versions (MA 2005). Together with the quantitative models (Alcamo et al. 2005) the storylines provide a base from which others can consider...

Landscape Change in the Southern Piedmont: Challenges, Solutions, and Uncertainty Across Scales Ecology and Society
Conroy, Michael J; USGS Cooperative Fish and Wildlife Research Unit; conroy@forestry.uga.edu; Allen, Craig; University of Nebraska; allencr@unl.edu; Peterson, James T; USGS Cooperative Fish and Wildlife Research Unit;; Pritchard, Lowell, Jr.; Emory University; lpritc2@emory.edu; Moore, Clinton T; ;.
The southern Piedmont of the southeastern United States epitomizes the complex and seemingly intractable problems and hard decisions that result from uncontrolled urban and suburban sprawl. Here we consider three recurrent themes in complicated problems involving complex systems: (1) scale dependencies and cross-scale, often nonlinear relationships; (2) resilience, in particular the potential for complex systems to move to alternate stable states with decreased ecological and/or economic value; and (3) uncertainty in the ability to understand and predict outcomes, perhaps particularly those that occur as a result of human impacts. We consider these issues in the context of landscape-level decision making, using as an example water resources and lotic...

Elevated Levels of Herbivory in Urban Landscapes: Are Declines in Tree Health More Than an Edge Effect? Ecology and Society
Christie, Fiona J; University of Sydney; christie@bio.usyd.edu.au; Hochuli, Dieter F; University of Sydney; dieter@bio.usyd.edu.au.
Urbanization is one of the most extreme and rapidly growing anthropogenic pressures on the natural world. Urban development has led to substantial fragmentation of areas of natural habitat, resulting in significant impacts on biodiversity and disruptions to ecological processes. We investigated the levels of leaf damage caused by invertebrates in a dominant canopy species in urban remnants in a highly fragmented urban landscape in Sydney, Australia, by assessing the frequency and extent of chewing and surface damage of leaves in urban remnants compared to the edges and interiors of continuous areas of vegetation. Although no difference was detected in the frequency of leaves showing signs of damage at small, edge, and interior sites, small sites suffered...

The Effects of Urban Sprawl on Birds at Multiple Levels of Biological Organization Ecology and Society
Blair, Robert; University of Minnesota; blairrb@umn.edu.
Urban sprawl affects the environment in myriad ways and at multiple levels of biological organization. In this paper I explore the effects of sprawl on native bird communities by comparing the occurrence of birds along gradients of urban land use in southwestern Ohio and northern California and by examining patterns at the individual, species, community, landscape, and continental levels. I do this by assessing the distribution and abundance of all bird species occupying sites of differing land-use intensity in Ohio and California. Additionally, I conducted predation experiments using artificial nests, tracked the nest fate of American Robins and Northern Cardinals, and assessed land cover in these sites. At the individual level, predation on artificial...

Biodiversity, Urban Areas, and Agriculture: Locating Priority Ecoregions for Conservation Ecology and Society
Ricketts, Taylor; World Wildlife Fund; taylor.ricketts@wwfus.org; Imhoff, Marc; NASA's Goddard Space Flight Center; mimhoff@LTPmail.gsfc.nasa.gov.
Urbanization and agriculture are two of the most important threats to biodiversity worldwide. The intensities of these land-use phenomena, however, as well as levels of biodiversity itself, differ widely among regions. Thus, there is a need to develop a quick but rigorous method of identifying where high levels of human threats and biodiversity coincide. These areas are clear priorities for biodiversity conservation. In this study, we combine distribution data for eight major plant and animal taxa (comprising over 20,000 species) with remotely sensed measures of urban and agricultural land use to assess conservation priorities among 76 terrestrial ecoregions in North America. We combine the species data into overall indices of richness and endemism. We...

Development of a Compendium of Local, Wild-Harvested Species Used in the Informal Economy Trade, Cape Town, South Africa Ecology and Society
Petersen, L. M.; University of Queensland, Australia; Sustainable Livelihoods Foundation, South Africa; Leif.petersen@livelihoods.org.za; Moll, E. J.; Department of Biodiversity and Conservation Biology, University of the Western Cape, South Africa;; Collins, R.; School of Agriculture and Food Sciences, University of Queensland, Australia;; Hockings, Marc T.; Department of Geography, Planning and Environmental Management, University of Queensland, Australia; m.hockings@uq.edu.au.
Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural norm, to being a subculture of commonly illicit activities located primarily within the urban, cash-based, informal economy. This paper focuses on Cape Town, South Africa where high levels of poverty and extensive population growth have led to a rapidly growing informal industry based on the cultural, subsistence, and entrepreneurial harvesting and consumption of products obtained from the local natural environment. Through a process of literature reviews, database analysis, and key informant interviews, a compendium of harvested species...

A mixed-methods analysis of social-ecological feedbacks between urbanization and forest persistence Ecology and Society
BenDor, Todd; University of North Carolina at Chapel Hill; bendor@unc.edu; Shoemaker, Douglas A.; North Carolina State University; douglas.shoemaker@gmail.com; Thill, Jean-Claude; University of North Carolina at Charlotte; Jean-Claude.Thill@uncc.edu; Dorning, Monica A.; North Carolina State University; madorning@gmail.com; Meentemeyer, Ross K.; North Carolina State University; ross_meentemeyer@ncsu.edu.
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’ 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...

Fast and furious: a look at the death of animals on the highway MS-080, Southwestern Brazil Iheringia, Sér. Zool.
Carvalho,Naira C. de; Bordignon,Marcelo O.; Shapiro,Julie T..
Several factors, such as hunting and the pet trade, are responsible for the worldwide decline of wildlife populations. In addition, fatal collisions with vehicles on highways have also taken one of the largest tolls. This study aimed to quantify the richness and abundance of vertebrate roadkill along highway MS-080 in Mato Grosso do Sul, Central-West Brazil. We compare the amount of roadkill to the distance between cities, moon phases and the flow of vehicles on the highway. Samples were collected weekly between March and September 2011, totaling 257 individuals, belonging to 32 families and 52 species, resulting in an index of 0.13 individuals hit/km. Birds were the most frequently hit taxa, followed by mammals. The most affected species was Cariama...

Helminths of introduced house sparrows (Passer domesticus) in Brazil: does population age affect parasite richness? Iheringia, Sér. Zool.
Calegaro-Marques,Cláudia; Amato,Suzana B..
Species introductions have altered host and parasite diversity throughout the world. In the case of introduced hosts, population age appears to be a good predictor of parasite richness. Habitat alteration is another variable that may impact host-parasite interactions by affecting the availability of intermediate hosts. The house sparrow (Passer domesticus (Linnaeus, 1758)) is a good model to test these predictions. It was introduced in several parts of the world and can be found across rural-urban gradients. A total of 160 house sparrows from Porto Alegre, state of Rio Grande do Sul, Brazil, were necropsied. Thirty house sparrows (19 %) were parasitized with at least one out of five helminth species (Digenea: Tamerlania inopina Freitas, 1951 and...

Occurrence of Hirudinea species in a post urban reach of a Patagonian mountain stream Iheringia, Sér. Zool.
Miserendino,M. Laura; Gullo,Bettina S..
Temporal (May 2005 to February 2006) and habitat distribution (pools and riffles) of Hirudinea species was analyzed at a post urban reach from Esquel stream (Chubut province, Patagonia, Argentina). Site was located 5.7 km downstream a Waste Treatment Plant. Mean values of nutrients: ammonia, nitrates and soluble reactive phosphate, as well water conductivity, turbidity and total suspended solids indicated physical and organic pollution. Leeches assemblage was composed by the glossiphonids: Helobdella scutifera Blanchard, 1900, H. michaelseni (Blanchard, 1900), H. simplex (Moore, 1911), Helobdella sp., H. hyalina Ringuelet, 1942, H. obscura Ringuelet, 1942 and the semiscolecid Patagoniobdella variabilis (Blanchard, 1900). From these H. hyalina and H....

A World for Reactive Phenotypes ArchiMer
Geoffroy, Benjamain; Alfonso, Sebastien; Sadoul, Bastien; Blumstein, Daniel T.
Humans currently occupy all continents and by doing so, modify the environment and create novel threats to many species; a phenomenon known as human-induced rapid environmental changes (HIREC). These growing anthropogenic disturbances represent major and relatively new environmental challenges for many animals, and invariably alter selection on traits adapted to previous environments. Those species that survive often have moved from their original habitat or modified their phenotype through plasticity or genetic evolution. Based on the most recent advances in this research area, we predict that wild individuals with highly plastic capacities, relatively high basal stress level, and that are generally shy—in other words, individuals displaying a reactive...

The outbreak of COVID-19 raised numerous questions on the interactions between the occurrence of new infections, the environment, climate and health. The European Union requested the H2020 HERA project which aims at setting priorities in research on environment, climate and health, to identify relevant research needs regarding Covid-19. The emergence and spread of SARS-CoV-2 appears to be related to urbanization, habitat destruction, live animal trade, intensive livestock farming and global travel. The contribution of climate and air pollution requires additional studies. Importantly, the severity of COVID-19 depends on the interactions between the viral infection, ageing and chronic diseases such as metabolic, respiratory and cardiovascular diseases and...

Urbanization and Waterborne Pathogen Emergence in Low-Income Countries: Where and How to Conduct Surveys? ArchiMer
Bastaraud, Alexandra; Cecchi, Philippe; Handschumacher, Pascal; Altmann, Mathias; Jambou, Ronan.
A major forthcoming sanitary issue concerns the apparition and spreading of drug-resistant microorganisms, potentially threatening millions of humans. In low-income countries, polluted urban runoff and open sewage channels are major sources of microbes. These microbes join natural microbial communities in aquatic ecosystems already impacted by various chemicals, including antibiotics. These composite microbial communities must adapt to survive in such hostile conditions, sometimes promoting the selection of antibiotic-resistant microbial strains by gene transfer. The low probability of exchanges between planktonic microorganisms within the water column may be significantly improved if their contact was facilitated by particular meeting places. This could...

The population ecology of Muscina stabulans (Fallén) (Diptera: Muscidae), along an Urban-Rural Gradient of Buenos Aires, Argentina Neotropical Entomology
Patitucci,Luciano D; Mulieri,Pablo R; Mariluis,Juan C; Schnack,Juan A.
The false stable fly, Muscina stabulans (Fallén), was surveyed along an urban-rural gradient at Almirante Brown, Buenos Aires province, Argentina. Samples were taken at monthly intervals from May 2005 to April 2007. Hourly captures of adult flies (10:00 am - 04:00 pm) were taken at each sampling date with a hand net. The baits used were 250 g of rotten cow liver and 250 g of fresh dog faeces exposed in shaded and sunny areas. The entire sample accumulated 358 specimens. The number of specimens captured during the second year was higher than in the fi rst year. Muscina stabulans was more abundant at urban-suburban sites. Females showed significant preferences for cow liver. We caught more specimens in shaded areas. The hourly activity increased toward the...

Local fish extinction in a small tropical lake in Brazil Neotropical Ichthyology
Pompeu,Paulo dos Santos; Alves,Carlos Bernardo Mascarenhas.
Lagoa Santa is a shallow permanent lake, located in Belo Horizonte metropolitan region, Brazil. In this study, the loss in fish diversity of the lake over the past 150 years is evaluated. Local extinction of almost 70% of the original fish fauna is described. Probably, the main causes of this richness loss were: obstruction of natural communication with rio das Velhas, non-native species introduction, change in the water level, organic pollution, and elimination of littoral and submerged vegetation.

Effects of abiotic variables on the distribution of fish assemblages in streams with different anthropogenic activities in southern Brazil Neotropical Ichthyology
Daga,Vanessa Salete; Gubiani,Éder André; Cunico,Almir Manoel; Baumgartner,Gilmar.
Studies on fish assemblages in streams point out, that understanding the relationship between species and their environment is crucial for conservation. The present study aimed at evaluating the effects of changes in abiotic variables on the composition and structure of fish assemblages in Neotropical urban streams from southern Brazil with different levels of urbanization. The composition and structure of fish assemblages showed significant differences along the urbanization gradient observed in the streams. Tolerant and non-native species were found in more urbanized sites. A matrix correlation revealed a relationship between abiotic variables and the spatial pattern of structure and composition of fish assemblages. Abiotic variables, such as total...
