What abiotic factors characterize salt marshes?

Salt marshes contain abiotic factors that release harsh salinity or too much amount of salt dissolved on their soil solution.
Here are some of the abiotic factors that characterize salt marshes
=> High amount of salinity
=> anaerobic soil
=> toxic from sulphide
=> high temperature
=> sudden changes to its photoperiod
=> scour and drag
=> The nutrient ions result to low proportion of the total amount present in the soil.
Thus, salinity and flooding are the major factors that affect salt marsh species

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
