k-selected species

Stable populations adapted to exist at or near the carrying capacity, K

Grow slowly and reach reproductive age late, having to devote much energy to growth and maintenance

K-selected species like a tree grows large and outcompeting  other  species

Such trees have a long-life span and produce seeds repeatedly when mature

These seeds are bigger

Antimicrobial peptides generally are cysteine-rich, cationic, and amphipathic. 

Because of their positive charge and amphipathic nature, they interact with acidic phospholipids in lipid bilayers, forming pores and disrupting the membranes of bacteria, fungi, parasites, and viruses.

Defensins and cathelicidin LL-37 are secreted constitutively by epithelial cells in many tissues, and are stored as well in neutrophil granules, where they contribute to killing phagocytosed microbes.
