Latitudinal gradient Rapoport's rule and Latitudinal gradients in species diversity Species richness increases from high latitudes to low latitudes.
The peak of the species richness is not at Equator. It is deduced that the peak is between 20-30°N. The tropics fall within this range which is about 24.3 degrees north and south and this attests to the fact that species richness and biodiversity is highest here. The gradient of species richness is asymmetrical about the equator. The level of species richness increase rapidly from the north region but decrease slowly from the equator to southern region.
Factors affecting species richness There is a strong inverse correlation in many groups between species richness and latitude: the farther from the equator, the fewer species can be found, even when compensating for the reduced surface area in higher latitudes due to the spherical geometry of the earth. Equally, as altitude increases, species richness decreases, indicating an effect of area, available energy, isolation and/or zonation (intermediate elevations can receive species from higher and lower).

Consider the following statements:1. Biodiversity is normally greater ...
Biodiversity in different latitudes and altitudes
Biodiversity refers to the variety of life on Earth, including the number of species, genetic diversity, and ecosystem diversity. The distribution of biodiversity is influenced by various factors such as climate, topography, and human activities. The given statements are:
1. Biodiversity is normally greater in the lower latitudes as compared to the higher latitudes.
This statement is correct because the equatorial regions receive more sunlight and rainfall, which leads to high primary productivity and diverse habitats. The tropics are home to the largest number of species, including many endemic species that are found nowhere else. As we move towards the poles, the climate becomes colder and drier, resulting in a decrease in species diversity.
2. Along the mountain gradients, biodiversity is normally greater in the lower altitudes as compared to the higher altitudes.
This statement is also correct because as we move up the mountain, the temperature and precipitation levels decline. This leads to the formation of different vegetation zones, each with its own set of species. The lower slopes of the mountain generally have a higher diversity of species as compared to the higher slopes. This is because the lower slopes have more habitable conditions, such as warmer temperatures and more moisture, which support a greater variety of plants and animals.
Conclusion
Thus, both statements are correct, and they highlight the importance of understanding the distribution of biodiversity across different latitudes and altitudes. Conservation efforts should take into account these factors to ensure the protection of species and habitats that are crucial for maintaining the planet's ecological balance.
