The article provides a widened understanding of the concept end-user flexibility and nuances traditional individual-oriented approach often used in discussions on low carbon transitions. authors draw 75 narratives from group end users that is considered to be very flexible stage life, namely students. They discuss co-production systems connected material, structural social factors extend beyond...

Seasonal cycles of temperature, water regime and day length act as “Zeitgeber” (timer) triggering stage transitions in the life cycle of organisms provoking temporal patterns of communities at different levels of organization. Climate change is both affecting temperature forcings and water regime. Mathematical models are set up to investigate the mechanisms for the change of temporal patterns i...

We address the problem of Markov chain Monte Carlo analysis of a complex ecological system by using a Bayesian inferential approach. We describe a complete likelihood framework for the life history of the wavyleaf thistle, including missing information and density dependence. We indicate how, to make inference on life history transitions involving both missing information and density dependence...

The life cycle of the African trypanosome Trypanosoma brucei, is characterised by a transition between insect and mammalian hosts representing very different environments that present the parasite with very different challenges. These challenges are met by the expression of life-cycle stage-specific cohorts of proteins, which function in systems such as metabolism and immune evasion. These life...

Some life transitions can be difficult to discuss on social media, especially with networks of known ties, due challenges such as stigmatization. Separate online provide alternative spaces transitions. To understand why and how people turn separate networks, we interviewed 28 participants who had recently experienced While prior research tends focus one transition in isolation, this work examin...

Habitat fragmentation is one of the principal causes of biodiversity loss and hence understanding its impacts on community assembly and disassembly is an important topic in ecology. We studied the relationships between fragmentation and community assembly processes in the land-bridge island system of Thousand Island Lake in East China. We focused on the changes in species diversity and phylogen...
