One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...

Plants, animals, fungi, bacteria and humans affect soil formation (see soil biomantle and stonelayer). Soil animals, including fauna and soil mesofauna , mix soils as they form burrows and pores , allowing moisture and gases to move about, a process called bioturbation. [ 75 ]
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
The carpels of pollinated female flowers ripen into fruits. The spathe and the upper part of the spadix wither away, leaving a short spike bearing a column of bright red fruits. These attract rhinoceros hornbills which eat the fruits and disperse the seeds around the rainforest. The spike dies back after around nine months, and the tuber ...
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.

Flies attracted to the moss carry its spores to fresh herbivore dung, which is the favoured habitat of the species of this genus. [27] In many mosses, e.g., Ulota phyllantha, green vegetative structures called gemmae are produced on leaves or branches, which can break off and form new plants without the need to go through the cycle of ...
