Human production needs are met through the use of modern technology that is increasingly recognised as a threat to the planetary ecosystem and social sub-system.

This work is mainly focused on the study of the interrelationships between transportation networks and the structure of the ecological communities in which the transport takes place. Transportation is a common need in many and diverse natural systems composed by individuals that interact with each other by competing for the same resources or by cooperation. For the cases we investigated we found that the features of the transportation system are closely related to the structure of the community. For example in tropical forests we showed that the optimization of the transportation of water an

Freshwater degradation has been largely attributed to excess nutrient concentrations of anthropogenic origin. Freshwater degradation in combination with water scarcity are the reason of severe stress on water resources globally. As one third of the world’s population does not have access to clean drinking water, nutrient pollution is imperative to be addressed. Nature-based solutions (NBS) is a recent concept to address several societal challenges, using techniques inspired by nature, or by nature itself, while preserving ecosystem sustainability.

This research seeks to understand the contemporary artistic labour of painting in a ‘post-aesthetic’ view, in which artistic knowledge is seen as socially situated, embodied, and emergent; existing in processes rather than artefacts. This has implications for understanding the ‘work’ of painting. Debates on artistic subjectivity and creative work ignore skilled and cognitive processes of labour (Taylor, 2011). An exception is Roberts (2007) who proposes that artistic subjectivity has become ‘decentred’, distributed across people, skills and tools. However, his labour theory does not address pa

Wildfires play a significant role in many different elements of Mediterranean forest ecosystems.

Apart from the fact that fire may alter microsite conditions, very little is known about the impact of prescribed burning on natural regeneration or plant species renewal in Mediterranean pine forests. Likewise, knowledge about the influence of seedling predators on post-fire regeneration is still scarce. In thi

Buffelgrass (Pennisetum ciliare) is a perennial bunchgrass native to Africa that has invaded ecologically intact areas of the Sonoran Desert in southern Arizona. It threatens many native plant species by means of competitive exclusion as well as increased fire frequency and intensity. Since the 1990s, efforts have been underway in southern Arizona to control buffelgrass using manual removal. A problem with this method is that the resulting bare, disturbed soil provides a favorable environment for buffelgrass seed germination.

As comunidades mudam no tempo e espaço em função de pressões decorrentes da estrutura do habitat e disponibilidade de recursos. O entendimento das relações ecológicas e interações das comunidades são essenciais para o manejo com objetivo de melhorar a qualidade da água através de interferências na cadeia trófica aquática e na dinâmica do ecossistema através de modelagem ecológica. O presente estudo foi desenvolvido em dois sistemas límicos subtropicais no extremo sul do Brasil: banhados temporários (‘campos de cultivo de arroz’) e um grande lago raso, lagoa Mangueira.

Biological invasions are a side effect of globalisation and human modification of natural systems. Invasive mosquitoes and the pathogens that they carry are leading causes of human suffering. Mosquito vectors of pathogens are often ecologically plastic and able to exploit human movements to disperse. As such they spread across wide geographical areas and are among the most successful species to have become invasive. Mosquito-borne pathogens have complex life cycles which involve a rich set of reservoir and vector hosts. They are evolutionarily very dynamic, ready to take advantage of new oppor

General scope. For much of human history the oceans have been considered incomprehensibly vast; an inexhaustible source of goods and services. Over the last century however, that paradigm has proved largely inaccurate. The ocean is in a state of crisis, caused primarily by human overexploitation. A rational reaction to the crisis is to limit fishing, often by designating swaths of the ocean as marine protected areas (MPAs). To be effective, it has been suggested that marine protected areas must cover between ten and thirty percent of the world’s oceans, ideally linked into MPA networks. Pr

A study conducted in Stave Reservoir, near Mission British Columbia, examined the linkages between flooded shoreline vegetation and associated periphyton and benthic communities in a coastal reservoir drawdown zone. Two native perennial species, woolgrass (Scirpus cyperinus) and lenticulate sedge (Carex lenticularis), and an annual agronomic species, fall rye (Secale cereale L.) were used in the study. A total of 108 pots containing either one of the plant species or barren substrate (i.e. no vegetation) were installed within three elevation bands in the inundated reservoir drawdown zon

Private Protected Areas (PPAs) are increasingly considered a promising complement topublic-run protected areas. Their rapid proliferation worldwide and increased adoption as policy tools, have made the PPA phenomenon one of the most important in current nature protection strategies. Nevertheless, there has been little scholarly attention paid to their emergence and the implications of their implementation, especially in Europe. This dissertation explores the genesis of PPAs as innovative institutional arrangements for conservation policies and investigates their suitability for enhancing natur

<p>Eastern black walnut (<i>Juglans nigra</i> L.) ranks among the most highly valued timber species in the central hardwood forest and across the world. This valuable tree fills a critical role in native ecosystems as a mast bearing pioneer on mesic sites. Along with other <i>Juglans</i> spp. (Juglandaceae), <i>J. nigra</i> is threatened by thousand cankers disease (TCD), an insect-vectored disease first described in 2009. TCD is caused by the bark beetle <i>Pityophthorus juglandis</i> Blackman (Corthylini) and the phytopathogenic fungus <i>Geosmithia morbida</i> Kol. Free. Ut. & Tiss. (Bionec
