The key was specialization.
Similarly to Burmeistera, which are also pollinated by bats and hummingbirds (Muchhala 2003), divergences in floral morphology in Ipomoea played a central role in pollinator specialization and made possible the co-occurrence and pollinator sharing in these taxa.
While some groups reported clustering of Kv4.2 subunits at synaptic specializations in central neurons (Alonso and Widmer 1997; Jinno et al. 2005), others showed Kv4.2 clustering at extrasynaptic sites (Kollo et al. 2006, 2008) or a non-homogeneous distribution along the proximo-distal axis of neuronal dendrites without the formation of any cluster (Kerti et al. 2011).
This course brings together two fields of specialization that are central to planners keen on working in international contexts: i) the field of international development, and ii) the political economy of urbanization.
Host density is a central species-specific trait explaining specialization and speciation of parasites because it affects probability of parasites locating preferred hosts.
What I plan to do in this article is weave together some tentative answers to these three questions with the story of Nasrudin around a central theme, namely, that of the specialization of the hemispheres of the human brain and what that specialization means for management.
The formation of postsynaptic specializations at excitatory central synapses has also been well studied.
Development of the neuromuscular junction (NMJ) is initiated by the formation of postsynaptic specializations in the central zones of muscles, followed by the arrival of motor nerve terminals opposite the postsynaptic regions.
The Central Plains region is suited to specialization in rice production because it has the largest irrigated area, allowing farmers to fully utilize the land.
EEG: Electroencephalography. DOI: http://dx.doi.org/10.7554/eLife.09215.026 Previously proposed mechanisms of arousal regulation have focused on the physiological and anatomical specialization of neurons within central thalamus (Schiff, 2008).
Cumulative models predict summation, but little interaction between these systems over development, whereas cascading effects models predict the opposite pattern, with systems playing a central role in each other's specialization.
