“…Many studies have shown the importance of water availability on phenology, especially in arid, semiarid (Bowers and Dimmitt 1994), and Mediterranean (Chiariello 1989, González Sierra et al 1996, Peñuelas et al 2004) systems. When low water availability is a stressor, it tends to delay phenology (Kelly 1992, Stanton et al 2000, Sultan 2001, however, when it is a cue of the end of the growing season, as in Mediterranean climates, it tends to be associated with more mature phenologies (Chiariello 1989), although responses are species specific (Peñuelas et al 2004).…”

Effects of microtopography and hydrology on phenology of an invasive herb

Phenological traits may influence invasion success via effects on invasiveness of the colonizing species and invasibility of the receiving ecosystems. Many species exhibit substantial fine-scaled spatial variation in phenology and interannual differences in phenological timing in response to environmental variation. Yet describing and understanding this variation is limited by the availability of appropriate spatial and temporal datasets. Remote sensing provides such datasets, but has primarily been used to monitor broad-scale phenological patterns at coarse resolutions, necessarily missing fine spatial detail and intraspecies variation. We used hyperspectral remote sensing to characterize the spatial and temporal phenological variation of the invasive species Lepidium latifolium (perennial pepperweed) at two sites in California's San Francisco Bay/SacramentoÁSan Joaquin River Delta. Considerable phenological variation was detected: L. latifolium was simultaneously present in vegetative, early flowering, peak flowering, fruiting, and senescent stages in late June; the relative dominance and distribution of these stages varied interannually. Environmental determinants of phenology were investigated with variables derived from the hyperspectral image data, from a high resolution LiDAR (light detection and ranging) digital elevation model (DEM), and from local precipitation and streamflow data. Lepidium latifolium phenology was found to track water availability, and may also be influenced by intraspecific competition and edaphic stress. Lepidium latifolium has a unique phenology (summer flowering) relative to the communities it invades, which may allow invasion of an empty niche. Furthermore, many habitats are invaded by L. latifolium, which occurs in locally appropriate phenologies under the different environmental conditions. The environmental responsiveness of L. latifolium phenology may mediate the wide breadth of invasible habitats.

“…The first group comprises the biological properties attained in the course of the species historical development. The exogenous factors are primarily climate factors (Diekmann 1996;Tyler 2001), soil conditions (Schwartz 1992;Sierra et al 1996;Wielgolaski 1999), structure of phytocoenose (Eliáš 1987;Kawarasaki & Hori 2001;Routhier & Lapointe 2002;Kikuzawa 2003).…”

Changes in the seasonal rhythm of two plant phytocoenoses in a submountain beech forest during secondary succession were studied. Investigations were done on four monitoring plots with different stand density over the period of four successive years. The rhythm of the associations Dentario bulbiferae-Fagetum and Carici pilosae-Fagetum reflects the course of succession processes running six years after the human impact (cutting) in the ecosystem. Results of the phenological observations of the understorey species with the focus on the changes in flowering and colour spectrum allowed to make the comparisons between both associations in connection with different phyto-climatic conditions and in dependence on time.The most conspicuous changes in the seasonal rhythm and structure of the examined associations were found in conditions of the former clear-cut, currently in succession phase. A clear decrease (56%) in number of taxons with the dominance > 1% in one association towards the end of the 4-year study period was detected here. Simultaneously, a decrease in the number of flowering species was observed, while the relative rate of species being in the vegetative stage increased considerably (from 6 to 67%) over the growing season. The course of flowering of both of the associations missed discernible trends and peaks as well as colour spectra were partially changed during four monitored successive years on the formerly unstocked area.

Insect Pest Management and Ecological Research

View full text Add to dashboard Cite

Insect Pest Management and Ecological Research explores the ecological research required for development of strategies to manage pest insects, with particular emphasis on the scientific principles involved in the design and conduct of pest-related research. Although the connection between Integrated Pest Management (IPM) and ecology has been long appreciated, their specific relationship to one another has remained vague until now. Here, Gimme Walter develops the first general model of the entomological research requirements of IPM. He shows how to navigate through the diversity of options presented by current ecological theory, emphasising pest situations. Besides theory and principle, the book includes practical advice on understanding and investigating species, examines the ecological problems associated with polyphagous pests and beneficial species, and scrutinises ways suggested to improve insect biological control. As such, it will be an important resource for graduate students and researchers, in IPM, insect pest management, entomology, ecology and crop protection.
