Establishing turf grass increases soil greenhouse gas emissions in peri-urban environments

Journal Articles & Books
Décembre, 2016
Global

Urbanization is becoming increasingly important in terms of climate change and ecosystem functionality worldwide. We are only beginning to understand how the processes of urbanization influence ecosystem dynamics and how peri-urban environments contribute to climate change. Brisbane in South East Queensland (SEQ) currently has the most extensive urban sprawl of all Australian cities. This leads to substantial land use changes in urban and peri-urban environments and the subsequent gaseous emissions from soils are to date neglected for IPCC climate change estimations.

Complex effects of fragmentation on remnant woodland plant communities of a rapidly urbanizing biodiversity hotspot

Journal Articles & Books
Décembre, 2014

In many cities worldwide, urbanization is leading to the rapid and extensive fragmentation of native vegetation into small and scattered urban remnants. We investigated the effects of fragmentation on plant species richness and abundance in 30 remnant Banksia woodlands in the rapidly expanding city of Perth, located in the southwestern Australian global biodiversity hotspot.

How has Oregon's land use planning system affected property values?

Journal Articles & Books
Décembre, 2012

Oregon's landmark land use planning system has been criticized for imposing large negative effects on landowners’ property values, although evidence to support these claims has been lacking. This paper examines longitudinal data for undeveloped parcels since before adoption of the planning system. The sample includes parcels under different land use regulations, and it compares Oregon to Washington.

Multinomial regression for analyzing macroinvertebrate assemblage composition data

États-Unis d'Amérique

Macroinvertebrate species composition data are often expressed as proportional abundances when assessing water-quality conditions or responses to disturbance. Proportional abundances represent the probability of belonging to one of many mutually exclusive and exhaustive groups (taxa). Proportional abundances have some unique properties that must be considered when analyzing these data: 1) the probabilities of group membership must sum to 1 and 2) a change in any 1 group affects all other groups.

Economic development, urban expansion, and sustainable development in Shanghai

Journal Articles & Books
Décembre, 2014

Studies of urbanization effects in Chinese cities from the aspect of the coupled development of economy and environment are rare due to data limitations. This paper studied Shanghai’s fast urban expansion and examined the dynamic relationship between economic growth and environment consequences at the district level. We extracted data on urban built-up area and land surface temperature from remote sensing images. We analyzed the patterns of urban expansion and land use change and explained the dynamic relationship between economic development and environment conditions.

Landscape legacies: Koala habitat change in Noosa Shire, South-east Queensland

Journal Articles & Books
Décembre, 2002

Present day Australian landscapes are legacies of our colonial history, while future landscapes will be legacies of ecological processes and human impacts occurring today. This paper investigates the legacies of European settlement of Noosa Shire, South-east Queensland, with particular emphasis on the economic and political drivers and the resultant loss and fragmentation of Koala Phascolarctos cinereus habitat.

Extreme habitat loss in a Mediterranean habitat: Maytenus senegalensis subsp. europaea

Europe

Maytenus senegalensis subsp. europaea communities are unique vegetal formations in Europe. In fact, they are considered Priority Habitat by Directive 92/43/EEC. These are ecologically valuable plant communities found in the southeast of Spain. By combining modeling methods of environmental variables, historical photo-interpretation, and fieldwork, a chronosequence of the evolution of their extent of occurrence (EOO) has been reconstructed in 1957 and 2011. Results showed a strong regression range of M. senegalensis subsp. europaea populations.

role of landscape configuration in plant composition of floodplain forests across different physiographic areas

Journal Articles & Books
Décembre, 2010

Questions: What is the relative importance of landscape variables compared to habitat quality variables in determining species composition in floodplain forests across different physiographic areas? How do species composition and species traits relate to effects of particular landscape variables? Do lowland and mountain areas differ in effects of landscape variables on species composition? Location: Southern Czech Republic. Methods: A total of 240 vegetation relevés of floodplain forests with measured site conditions were recorded across six physiographic areas.

Good neighbours: distribution of black-tufted marmoset (Callithrix penicillata) in an urban environment

Journal Articles & Books
Décembre, 2015

Context Primates are one of the most charismatic and widely studied vertebrate groups. However, the study of new world primates in green patches within urban areas has been neglected. Such primates have been viewed as a source of human–animal conflict; however, their ecological importance to urban ecosystems and their role in human well being is poorly understood. Aims To increase understanding of both ecological and socioeconomical factors affecting the distribution, density and group sizes of urban marmosets in a large Brazilian city (Belo Horizonte).

Evaluating patterns of human–reptile conflicts in an urban environment

Journal Articles & Books
Décembre, 2015
Brésil

Context Reptiles, especially snakes, can cause a fear reaction in the public and are, therefore, a good model to examine human–wildlife conflicts. Human city dwellers often respond to the presence of snakes or other reptiles by calling out the responsible agency for animal control, which has to mediate the situation. Aims To determine how the temporal and spatial occurrence of human–reptile conflicts were associated with environmental conditions and socio-economic factors in a large Brazilian city (Belo Horizonte).

rapid and massive urban and industrial land expansions in China between 1990 and 2010: A CLUD-based analysis of their trajectories, patterns, and drivers

Journal Articles & Books
Décembre, 2016
Chine

The past two decades saw rapid and massive urbanization and industrialization in China. Despite much research has been reportedly done at local and regional scales, little has been reported on the trajectories, patterns, and drivers of these two intertwining processes at the national level. This is mainly due to the fact that until recently, high resolution spatial data of land use and land cover change were not available at national level. The research reported in this paper aimed to fill this knowledge gap.
