1. Spring Phenology of Butterflies : The role of seasonal variation in life-cycle regulation
Sammanfattning : Animals and plants in temperate regions must adapt their life cycle to pronounced seasonal variation. The research effort that has gone into studying these cyclical life history events, or phenological traits, has increased greatly in recent decades. LÄS MER
2. Geographic variation in life cycles : Local adaptation and ecological genetics in a temperate butterfly
Sammanfattning : Conditions in nature change with the seasons, necessitating seasonal adaptations that synchronize the life cycles of organisms with their surroundings. Such regulatory adaptations must vary between populations to track local variation in climate and seasonality; this local adaptation is facilitated by locally specific seasonal cues, but may be hampered by gene flow and genetic history.

3. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle
Sammanfattning : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. LÄS MER
4. An Emerging Product Approach in Environmental Law: Incorporating the life cycle perspective
Sammanfattning : One of the noticeable trends in recent years is that products have received increasing attention in environmental policy. The focus on products and their life cycle impacts is often referred to as ?life cycle thinking?. LÄS MER
5. Regulation of differentiation during the Giardia life cycle : An insight into the molecular control
Sammanfattning : Giardia intestinalis (syn. G. lamblia, G. duodenalis) is an intestinal protozoan parasite that causes diarrheal infections worldwide. LÄS MER
