Abstract:
Butterflies fulfill a unique role among insect pollinators as long-distance flyers. This makes butterflies particularly valuable as vectors of genetic diversity among spatially isolated plant populations. Like many insects, though, butterfly populations have experienced significant declines in recent years. To help inform conservation efforts, and to investigate community and species level dynamics, I studied butterflies and their floral resources as part of a three year pollinator survey across the state of North Dakota. At the community level, I analyzed butterfly-flower interaction networks

Abstract:
Relying on wild bees for pollination services has become necessary as the global demand for crops dependent on animal pollination increases. If wild bee populations are to establish and persist in agricultural landscapes, there must be sufficient floral resources over time and space. This study examines the relationship between bee visits in agroecosystems and the spatiotemporal availability of floral resources over one season. I expected that landscapes with greater floral resources earlier in the season would subsequently experience more bee visits than landscapes with fewer early-season flo

Livestock management influences the extent to which grazing lands provide resources for native species.

Increases in agricultural intensification over the past century have resulted in significant alterations to the rural landscape across the Midwest. Pollinators are essential to sustain natural and managed ecosystems. They are vital for food production and their declines have been linked, in part, to a rise in intensive agricultural practices. There is a recognized need among numerous stakeholders to build sustainability into the management of agroecosystems to protect both the biotic and abiotic resources of these systems.

Flower seed mixes are increasingly used to enhance the biodiversity and amenity values of urban green spaces. Urban or “pictorial” flower seed mixes are often used because they are designed using cultivars and non-native species to provide more colourful and longer-lasting flower displays. Although these seed mixes are effective in providing a high density of large colourful flowers, over an extended season, their value for biodiversity, and in particular the floral rewards they provide for flower-visitors, is largely unknown.

This research presents a Resource-constrained Critical Path Method (RCPM) technique that capitalizes on and improves the existing Critical Path Method (CPM) and Resource-Constrained Scheduling (RCS) techniques. A traditional CPM schedule is not realistic since it assumes unlimited resources, some of which are highly limited in practice. Although traditional RCS techniques can consider resource limitations, they do not provide correct floats and the critical path as the CPM does. The difference between the theoretical remaining total float and the real remaining total float is referred to as

Abstract:
A heterogeneidade comum aos sistemas biológicos, sua influência na interação planta-polinizador e demografia de uma arvoreta tropical são os temas centrais desta tese. Utilizando uma abordagem hierárquica de estrutura de manchas de recursos florais: 1. caracterizamos a variação espaço-temporal na disponibilidade de recursos florais aos morcegos e beija-flores, polinizadores de Abutilon rufinerve. 2. avaliamos a existência de indícios de efeitos positivos ou negativos da densidade de A. rufinerve na atração de visitantes florais, em seu comportamento e possíveis conseqüências para a produção de

Abstract:
Conserver les espèces pollinisatrices est un enjeu majeur, notamment en milieu agricole où elles sont indispensables à la pollinisation de différentes cultures. Ici, nous avons décidé de caractériser ces espèces et leurs ressources florales dans une plaine céréalière intensive, à travers l’utilisation de plusieurs années de données acquises grâce à plusieurs protocoles d’échantillonnage. Cette plaine se caractérise par une forte dynamique spatio-temporelle, résultant des floraisons massives mais brèves des cultures oléagineuses. Nous avons recensé sur cette plaine près d’un tiers des espèces d

Depuis plus de 30 ans, la Colombie construit sa politique de préservation des espèces faunistiques et de lutte contre le trafic illégal de ces espèces. Ce cadre institutionnel national s’est vu renforcé par la ratification de la convention CITES (Convention sur le commerce international des espèces de la flore et de la faune sauvages menacées d’extinction) en 1981. Pourtant, ce cadre institutionnel ne suffit pas à infléchir sur le trafic illégal des tortues marines en Colombie.

Malaria still remains one of the world’s biggest killers with more than two million people dying from the disease each year. Present drugs have become ineffective because parasites are developing resistance to most of them. Efforts are now being directed in obtaining drugs with different structural features. Plants have provided most of the antimalarial drugs so far and efforts now concentrate on screening plants for new antimalarial drugs. South Africa with its rich floral resources and ethnobotanical history is an ideal place to screen plants for antimalarial activity. The antimalarial activ
