Abstract:

The interaction of herbivory and pollination is not well understood. Both topics on their own have been studied thoroughly, yet their interaction has not. Until the 1990s, few studies attempted to explore how herbivory might affect pollination, and vice versa.

Entretanto, estudos sobre seus imaturos (ovo, larva e pupa) ainda são incipientes para o bioma, principalmente sobre as mariposas, cujas histórias naturais de muitas espécies ainda são desconhecidas. A falta desses estudos faz com que sejam ignoradas as interações multitróficas em que esses organismos estão envolvidos e, portanto, inviabiliza futuros estudos relacionado

Abstract:

Corals, the foundation species of tropical reefs, are in rapid global decline as a result of anthropogenic disturbance. On many reefs, losses of coral have coincided with the over-harvesting of reef herbivores, resulting in ecosystem phase-shifts from coral to macroalgal dominance. It is hypothesized that abundant macroalgae inhibit coral recovery and recruitment, thereby generating ecological feedback processes that reinforce phase-shifts to macroalgae and further diminish reef function. Notwithstanding, the extent to which macroalgae directly outcompete coral, the mechanisms involved, and th

Herbivory, fact of animals feeding all, exudations, tissues or parts of plants, is pointed like one of the most important points in the vegetation structuralization and diversity. That can be influenced by some factors, the most importants are seasonality, spatial variation, environment and plant-herbivory-predator interactions. Native species from Cerrado are also influenced by fire. In response to herbivory attack, the plants have different defenses strategies, it can be chemical, physical and/or biotic.

The density of nearby male plants had a positive effect on fruit set in both insect and wind pollinated catkins, but the effect was stronger in wind-only pollinated catkins. In insect pollinated catkins, catkin characteristics such as length and total number of flowers were

Abstract:

For decades scientists believed that herbivory had minimal impact on freshwater ecosystems. We now know that herbivory in freshwater systems equals or exceeds herbivory in terrestrial and marine systems. In extreme cases, herbivores can change clear, macrophyte dominated ecosystems into turbid plankton dominated ecosystems. Even though research on plant-herbivore interactions in freshwater systems has increased, there is still much that is unknown. This thesis is comprised of four studies investigating freshwater plant-herbivore interactions across multiple spatial scales. The first stud

Abstract:

Co-evolutionary interactions between plants and herbivores are suggested to be the driving force behind the high diversity observed in plant secondary metabolites. These compounds play an important role in herbivore resistance mechanisms in many plant species. An individual plant can produce and store a number of structurally different secondary compounds. Variation in plant chemical profiles is commonly observed within and between natural populations across a wide range of taxa, yet the ecological importance of this variation is still a major question in the area of plant-herbivore interactio

Abstract:

Global environmental change fundamentally affects plants and their interactions with other species, and this has profound impacts on communities and ultimately ecosystems. In order to understand the mechanisms involved, we need to elaborate on the combined effects of different global change drivers on multiple levels of plant organization, including the biochemical level (production of defence compounds), the whole organism, the population, and the plant-herbivore interaction level.

Rising temperatures associated with climate change will alter the fundamental physiological processes of most ectothermic species. Drastic changes in catabolic and anabolic reaction rates exert strong effects on growth, reproduction, and consumption rates that cascade up through all levels of the biological hierarchy. This dissertation determined how climate warming might alter the important relationship between plants and insect herbivores, as mediated through changes in herbivore physiology. Consumption and fitness increased with temperature for almost all consumers. However, all consumers a

Marine seaweeds constitute one of the most productive plant systems known on Earth and a rich fauna including juvenile fish and crustaceans is dependent on the habitats they form.

The area is subject to isostatic rebound, amounting to 0.85 cm per year; this makes it possible to calculate the age of the rising islands. Meadowsweet colonizes new islands when they are about 10

This thesis explains two aspects of animal spatial foraging behaviour arising as a direct consequence of animals' need to drink water: the concentration of animal impacts, and the response of animals to those impacts. In semi-arid rangelands, the foraging range of free-ranging large mammalian herbivores is constrained by the distribution of drinking water during the dry season. Animal impacts become concentrated around these watering sites according to the geometrical relationship between the available foraging area and the distance from water, and the spatial distribution of animal impacts be

Spatial variation in abiotic and biotic factors creates local contexts that influence the intensity and outcome of plant-herbivore interactions. Previous studies have tried to represent the complexity of these context dependencies using latitudinal clines, but this approach has proven insufficient for many systems. Despite substantial variation in herbivore damage across populations, the relative contribution of local community factors to explaining this variation is less well known.

This is contrasted with a hypothesis that predicts positive plant-plant interactions in high alpine environments.
