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?
It is believed by many researchers to have had no significant effect on cranial capacity and how the brain worked, the conclusion of a 1989 study of skulls in The American Journal of Physical Anthropology. The compression may have affected the shape of the face more than the brain itself, they said
Are high foreheads a sign of intelligence?
This feature has been considered a sign of heightened intelligence in many cultures through the ages. Forehead If this is broad, the person will be generous, intelligent and wise. And when it is short, it denotes he will be poor and likely to die young
Does skull shape affect intelligence?
Science says larger brains are correlated with higher intelligence, but size alone isn’t the cause. So yes: On average, people with bigger heads tend to be more intelligent
What does head binding do to the brain?
However, numerous studies have indicated that head binding has only negligible effects on the skull itself and that the inevitable modification of brain shape has no unfortunate side-effects. As long as the volume of the brain is unchanged, its functioning seemingly remains unimpaired
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.
Why did Mayans shape their heads?
Both the Mayans and the Inca shaped their children’s skulls, as did the Choctaw and the Chinookan tribes in what is now the United States. Their reasons must have been the same, to allow for the child to fit into the fabric of their societies, and to signify class. For the Maya, it also held a religious significance

What is a normal baby head shape?
What is Normal? Parents spend so much time with their baby, recognizing an abnormal head shape can sometimes be difficult. We’ve found it can be helpful to see examples of a normal head shape before looking at abnormal ones. Normally, the head is about 1/3 longer than it is wide and rounded at the back.
How long does it take for baby’s head to round out?
It can take 9-18 months before a baby’s skull is fully formed. During this time some babies develop positional plagiocephaly
Is it normal for a baby head to be misshapen?
It is not unusual for a baby’s head to look a little lopsided. Because the individual bones of a newborn’s skull aren’t yet fused together, pressure from resting in the same position can cause an infant’s head to be misshapen. This may include a flattened area
Can flat head be corrected after 6 months?
For a helmet to be effective, treatment should begin between 4 and 6 months of age. This will allow for the helmet to gently shape your baby’s skull as they grow. Treatment is generally considered ineffective after age 1 because the skull has started to fuse together
What is the most common misshapen baby head?
3 common misshapen head types Common positional skull deformities do not require surgery. Deformational brachycephaly is when the head is symmetrically (evenly) flat in the back and wide from side to side. The bone above the ears might seem to stick out
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.
At what age is craniosynostosis diagnosed?
But as your baby grows, a misshapen head could be a sign of something else. The earlier you can get a diagnosis—ideally, before the age of 6 months—the more effective treatment can be. Craniosynostosis is a condition in which the sutures in a child’s skull close too early, causing problems with head growth.
What are the effects of craniosynostosis?
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.
What happens after craniosynostosis surgery?
After craniosynostosis surgery, there will be sutures (stitches) across the top of your child’s head from ear to ear. There will also be a shaven strip of hair. Your child’s face will be very swollen, and their eyelids may be swollen shut. Their forehead will appear very prominent.
What is the surgery for craniosynostosis?
Cranial vault remodeling: This is the surgical approach that doctors have relied on for decades to treat craniosynostosis. This is typically performed for babies 5-6 months of age or older. In this surgery, a team of doctors:. Makes an incision along a baby’s scalp.
How long is recovery after craniosynostosis surgery?
The patient’s energy level will also improve 3-5 days after surgery. Following open cranial vault remodeling, the segments of the skull are held together with plates and screws that will dissolve after 8-12 months. The bones will be healed 6 weeks after surgery but trauma to the head should be avoided.
Can craniosynostosis be prevented?
Can Craniosynostosis be prevented? Genetic counseling is recommended to detect chromosomal and genetic forms of Craniosynostosis. Nothing is known to prevent isolated cases of the disorder. Pre-natal exposure to cigarette smoking 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.
