Finally, vegetation plays a key role in each watershed’s micro-climate. Plants pull water from the soil through their roots and transpire it from their leaves. Plants in fog-prone regions have evolved ways to collect the cloud moisture directly onto their leaves and needles, directing the moisture to then fall to the ground to help moisten the soil and be available to Chapter 2. Freshwater Fundamentals: Watersheds, Freshwater Ecosystems, and Freshwater Biodiversity plant roots. The more heavily vegetated a watershed, therefore, the more water gets taken out of the soil, and sometimes out of the air itself, and released back to the atmosphere without ever reaching a freshwater body.

Many species are restricted to single lakes or river basins. Endemic fish species are the basis of important fisheries in inland waters in tropical and temperate zones. Vertebrates: amphibians Frogs, toads, newts, salamanders, caecilians. Require freshwater habitats. Larvae of most species need water for development Some frogs, salamanders, and caecilians are entirely aquatic; generally in streams, small rivers, and pools. Larvae are typically herbivorous grazers, adults are predatory. Vertebrates: reptiles Turtles, crocodiles, lizards, snakes.

Life is constantly in motion, reproducing, growing and dying, and evolving through natural selection. This grand drama plays out on a stage of environmental variation, in which the details of climate and geology change daily, seasonally, yearly, and over longer periods of decades, centuries, and millennia. Wet seasons vary with dry ones, wet years vary with droughts, watersheds slowly erode, lakes fill up with sediment, and rivers meander. Sometimes these details change only slightly or gradually; sometimes they change catastrophically as a result of floods, disease epidemics, earthquakes, or volcanic events.
