Zonation on a rocky shore essays

Zonation on a rocky shore essays The seashore is a habitat that contains a wide range of microhabitats and ecological niches for different creatures. This is mainly due to the effects of the tides, that rise and fall twice each day. Tides are the vertical movement of water in a periodical oscillation of the sea, due to the gravitational pull of the sun and moon. The tides are on a semi-diurnal cycle, so there are two high tides and two low tides each day. Due to the orbit of the moon, the tides also have a monthly cycle. This creates neap (very low) and spring (very high) tides. The seashore can be divided into several zones, which are illustrated on the diagram below: This is the highest zone on the shore, and lies above the EHWS mark, and therefore is never covered by seawater. However, it may be occasionally be spray wetted. Because of this, it is mainly inhabited by terrestrial species, such as lichen, that can live in areas of very high salinity. This zone is the area that is covered and uncovered by the tides, and therefore organisms that live here must be able to tolerate a large range of conditions. It can be further divided into the Littoral Fringe and the Eulittoral zone. This part of the Littoral zone lies above the area that is completely submerged by the sea in normal conditions. However, it is frequently covered by splash from waves, and so is far more marine in character that the Supralittoral Zone. Lichens still dominate this zone, but some species of periwinkles and topshells may graze them. This zone is the area of the beach that is regularly submerged by the tides, and can be divided into three more zones, the upper, middle and lower shores. It shows the greatest species diversity of any of the zones. This region of the shore lies between the EHWS and MHWN marks, and so is only immersed during spring tides. Because of this, organisms that live here must be adapted to survive long periods of desiccation. The two seaweeds t...

Population Research Paper Example | Topics and Well Written Essays - 1000 words - 1

Population - Research Paper Example The interrelationship that exists between these parameters has been exploited as determinants of the constraints that are evidenced in the world’s geographical scope, and as platform to control and fight against world poverty. The essence of this paper is to examine the world population growth trends by analyzing the population characteristics in different countries in Africa, US, Europe, Asia, Middle East and South America. The Total Fertility Rate and Maternal Mortality rate The total fertility rate refers to the number of children per woman in a country and it provides the potential of the population of a given country to grow or increase. On the other hand, the maternal mortality rate refers to the number of women who die while in the process of delivering a child and is a unique characteristic that is variable in many countries depending on various factors such as health and nutrition. The charts below indicate the ranking of different countries both by total fertility ra te and maternal mortality rate. The statistics indicate that there is a great tie between the total fertility rate and the maternal mortality rate in the different sample countries. Countries with high total fertility rate have high maternal mortality rate and those with low fertility rate indicate low maternal mortality rate. ...

On the other hand, the Life expectancy at birth refers to the age at which a child is expected to attain at if the mortality rate in a given environment is assumed to be constant throughout the life period. The infant mortality rate is used to measure the quality of maternal care and health during the early ages of child bearing while the life expectancy at birth is a measure of the optimal life span of individuals in a country. The charts below indicate the ranking of sample countries both by infant mortality rate and the life expectancy at birth. The population growth rate is dependent on the infant mortality as the number of individual in a country will only increase is depends on the number of children who are born and are able to live a full life. If a country has a high infant mortality rate, then a high number of children die at a tender age, meaning that the population of such a country will grow slowly. Again, the life expectancy
