Final answer:
Many species exhibit diverse mixing patterns or display seasonal variations in their distribution and life history events (phenology), influenced by environmental factors and human activities. These patterns can take forms such as uniform, random, or clumped distribution.
Step-by-step explanation:
Many species exhibit a combination of mixing patterns or have seasonal mixing patterns. This phenomenon is mainly observed among species adapting to various environmental conditions or those with diverse life history strategies. For instance, angel, M. V. discusses the spatial distribution of marine organisms and how patterns and processes vary significantly. Briggs, J. C. provides insight into the Indo-west Pacific ocean's coincident biogeographic patterns that are indicative of particular distribution strategies.
Some species show changes in the timing of their life histories, known as phenology, which includes earlier flowering for some plant species or earlier egg-laying for certain animals like tree swallows. Specific distribution patterns include uniform distribution, as seen in territorial birds like penguins, random distribution, such as with wind-dispersed seeds of plants like dandelions, and clumped distribution exhibited by group-traveling animals like elephants. These patterns can also be influenced by various factors, such as environmental changes, human activities that create mosaics of land uses, and variations in phenology triggered by climate change.
