What is a phenological study?

Phenology, the study of phenomena or happenings. It is applied to the recording and study of the dates of recurrent natural events (such as the flowering of a plant or the first or last appearance of a migrant bird) in relation to seasonal climatic changes. Phenology thus combines ecology with meteorology.

What are the things that influence phenology?

Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).

What happens if phenology changes?

If the phenology of a species is shifting at a different rate from that of the species that make-up its ecological conditions, this will lead to mistiming of its seasonal activities (Visser et al. 2004) or, to use an alternative terminology, to a mismatch in phenology (Stenseth & Mysterud 2002)

What is phenology and why is it important?

Phenology influences the abundance and distribution of organisms, ecosystem services, food webs, and global cycles of water and carbon. Changes in phenological events like flowering and animal migration are among the most sensitive biological responses to climate change.

How is phenology affected by climate change?

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather.

Does skull shape affect brain?

Is Head binding still practiced today?

Intentional cranial deformation predates written history; it was practiced commonly in a number of cultures that are widely separated geographically and chronologically, and still occurs today in a few areas, including Vanuatu.

Is craniosynostosis a birth defect?

Craniosynostosis is a birth defect in which the bones in a baby’s skull join together too early. This happens before the baby’s brain is fully formed. As the baby’s brain grows, the skull can become more misshapen.

Craniosynostosis can occur by itself or as a part of certain craniofacial (head and facial) syndromes. If left untreated, craniosynostosis can lead to serious complications, including: Head deformity, possibly severe and permanent. Increased pressure on the brain.

Is craniosynostosis surgery safe?

The surgery is very safe and produces excellent results. There are several surgical options for treating craniosynostosis, depending on which type it is. It’s usually best to perform surgery at just a few weeks to a few months of age, since the skull bones are the softest and most malleable then.

The bones will be healed 6 weeks after surgery but trauma to the head should be avoided.

Can craniosynostosis be fixed without surgery?

Because of the progressive nature of the cranial deformity, most children with craniosynostosis are recommended for surgery. However, children with mild deformities or those who present late without signs of increased intracranial pressure (ICP) are occasionally treated without surgery

Can craniosynostosis be fixed?

The main treatment for craniosynostosis is surgery, usually within the first year of life. Surgery can help the skull to develop normally and allow space for the brain to develop. Without surgery, the shape may become more unusual, and this can lead to complications.
