Detritus occurs in a variety of terrestrial habitats including forest, chaparral and grassland. In forests, the detritus is typically dominated by leaf, twig, and bacteria litter as measured by biomass dominance. This plant litter provides important cover for seedling protection as well as cover for a variety of arthropods, reptiles [4] and ...
Detritus (/ d ə ˈ t r aɪ t ə s /; adj. detrital / d ə ˈ t r aɪ t əl /) is particles of rock derived from pre-existing rock through weathering and erosion. [1] A fragment of detritus is called a clast. [2] Detrital particles can consist of lithic fragments (particles of recognisable rock), or of monomineralic fragments (mineral grains).
Distribution of detritus. Provenance is the reconstruction of the origin of sediments. All rock exposed at Earth's surface is subjected to physical or chemical weathering and broken down into finer grained sediment. All three types of rocks (igneous, sedimentary and metamorphic rocks) can be the source of sedimentary detritus. The purpose of ...
Etymology The word faeces is the plural of the Latin word faex meaning "dregs". In most English-language usage , there is no singular form, making the word a plurale tantum ; [ 31 ] out of various major dictionaries, only one enters variation from plural agreement .
Bat guano is integral to the existence of endangered cave fauna. The critically endangered Shelta Cave crayfish feeds on guano and other detritus. [64] The Ozark cavefish, a U.S. federally listed species, also consumes guano. [61] The loss of bats from a cave can result in declines or extinctions of other species that rely on their guano.
A clast is a fragment of geological detritus, [1] chunks, and smaller grains of rock broken off other rocks by physical weathering. [2] Geologists use the term clastic to refer to sedimentary rocks and particles in sediment transport, whether in suspension or as bed load, and in sediment deposits.
Volcaniclastics are composed of a range of pyroclastic detritus mixed with epiclastic sediments and formed in variable depositional environments. [7] [8] Volcaniclastics include pyroclastic rock and tephra; volcanic autoclastic, alloclastic, and epiclastic materials; and fault gouge where faults displace volcanic rock. [2] All are defined below.

Below normal wave base, but not necessarily below storm wave base [1] [4] Zoophycos [1] Zoophycos, Phycosiphon, Chondrites [1] [4] Marine softground, impure sands and silts [1] Deeper water, bottom of shelf; turbidite facies [1] Nereites [1]
