Abstract:

Little is known about the composition of tropical epiphytic communities and the influence of environmental variables on community composition. In this thesis I quantify the diversity and biomass of bromeliads, and other vascular epiphytes along an altitudinal transect on the eastern slope of the southeast Peruvian Andes and then look for species’ adaptations related to patterns of diversity and biomass. I compare patterns with those of woody species. Bromeliad species, like tree species, were found to form ecological zones related to climate. The lowest altitude ecological zone (below 1250 m)

Abstract:

Landscape ecology has been defined in a variety of different ways, but the common theme is the study of the ecological effects of ecosystem spatial patterning. Since the long history of landscape alteration has created novel systems with unknown dynamics, new tools are necessary to understand, manage and restore human dominated landscapes, preventing the loss of biodiversity. Among all, habitat fragmentation is the main process which affects biodiversity especially in human dominated landscapes. This thesis is based on three research papers concerning the evaluation of plant species diversi

Abstract:

The plants of San Quintín (Baja California, Mexico) were documented through intensive fieldwork and the collection of herbarium specimens to create a checklist of species. This region is home to a diverse flora with high levels of local endemism and many rare plants. The flora documented in this study was compared to historical records from the region and shows the impact of agriculture and urbanization on the plants, including several extirpated species. A study of the perennial vegetation using a 1 km grid provides species distribution data for 140 native species, which were assessed to high

In addition, the hardstem bulrush (Scirpus lacustris glaucus (Sm.) Hartm) litter present was replaced with a non-nutritive artificial substrate in half of the fertilized and unfertilized enclosures. Fertilization did not affect the dry weight loss of bulrush litter, but N and P concen

Abstract:

Habitat loss and fragmentation are believed to be two of the main reasons for high extinction rates of species, resulting in decreased biodiversity. According to the island biogeography theory, the species richness in a patch, here a semi-natural grassland, is dependent on the landscape composition, and therefore changes in the landscape composition will result in changes in the species richness of the grassland. However, this change in species richness may be delayed for several years, causing an extinction debt. The aim of this study was to examine the change of species richness of vascular

L'hétérogénéité du paysage, définie par la composition en habitats et leur configuration spatiale, est considérée comme un facteur majeur affectant la biodiversité. Cependant, les effets de la composition et de la configuration sont souvent confondus du fait de corrélations entre les descripteurs de ces deux composantes. Il est crucial de déterminer leurs effets indépendants pour comprendre les processus qui contrôlent la biodiversité, et allouer les ressources dédiées à la conservation des espèces aux actions de gestion les plus pertinentes. L'objectif de cette thèse est, grâce à la mise en p

Abstract:

The proportion of resources which an organism devotes to reproduction has been assumed to be of great evolutionary and ecological significance. However, in previous studies of reproductive allocation (RA) in plants, there has been no consensus of precisely what is being measured nor how it should be measured. An attempt was made to determine the 'best' method of measuring RA and then apply this to a range of species with differing ecological strategies. Under nutrient stress caused by a low N treatment Taraxacum officinale and Poa annua were found to maintain their RA despite up to 4 fold redu

Con este fin se realizaron viajes de colectas, visitas a herbarios y se recopiló toda la información accesible de publicaciones y bases de datos. Se reportan 51 lomas de las cuales 39 fueron evaluadas en cuanto a su flora (21 por colecta propia y 18 desde publicaciones y registro de herbarios). Las Lomas fueron clasificadas respecto a su geografía en tres categorías: oceánicas, montañas aisladas o aso

Abstract:

As discussed in Chapter 1, although our understanding of the ecology and evolution of carnivorous plants has greatly improved in recent years, many fundamental questions remain unanswered. Unfortunately, at the present time, many carnivorous plants are increasingly threatened by anthropogenic activities. Indeed, over half of the carnivorous plant species assessed by the International Union for the Conservation of Nature (IUCN) are listed as `threatened', but the threats to carnivorous plants have not previously been quantified. In Chapter 2, I quantified the conservation threats to carnivor

Abstract:

I have isolated and characterized a recessive mutation in the Forked (FKD) gene that results in the abnormal initiation of vascular bundles in the foliar organs, such that the apices of the vascular bundles initiate freely. Once initiated, the development of Fkd vascular bundles is like wild type, generating an open vascular pattern of similar complexity to the closed venation pattern of wild type. Despite the significant alteration in the vascular pattern, Fkd plants are morphologically indistinct from wild type. fkd mutants do not show altered sensitivity to the effects of auxin and show add

Abstract:

Mycorrhizal mutualisms between aboveground vascular plant communities, which reward their belowground fungal associates with photosynthates in return for growth-limiting nutrients such as phosphate, are widely recognized as stable long-term interactions which helped plants colonize land.

Abstract:

It has been suggested that pollutant nitrogen inputs adversely influence the response of heathland plants to certain climatic and biotic stresses. One specific hypothesis being that elevated nitrogen deposition may reduce drought tolerance in heathland vegetation. However, there is little evidence from field studies that this is the case. The aims of this research project have been firstly to establish the effects of increased nitrogen inputs upon plant water relations in certain dwarf heathland shrubs under winter and summer drought conditions. Secondly, to contribute to the understanding of
