Our predictions were: (1) primate abundance will differ between the two sites; (2) density and richness of seedlings and saplings will be greater at the site with higher primate abundance; (3) the site with lower primate abundance will be characterized by higher seedling and saplings density and richness of tree species dispersed abiotically, or by other biotic dispersers (e.g.
Should life truly exist on an exoplanet, detecting nitrogen as well as oxygen could help astronomers verify the oxygen's biological origin by ruling out certain ways oxygen can be produced abiotically, or through means other than life.
In this abiotically constrained environment, the ant fauna and their behavior are poorly known even though being important on multitrophic interactions with plants and herbivores (Byk and Del-Claro, 2011; Fagundes et al., 2013; Romero, 2002; Sousa-Souto et al., 2008).
For the Pollination trait, taxa were considered to be abiotically pollinated if the flowers are nonexistent (conifers) or are not showy and not known to produce any sensory attractants.
However, PAHs are also known to form abiotically as solar radiation interacts with space dust, which means they could have been present in the rocks that initially came together to form Mars.
Such large seeds are unlikely to be buried abiotically (Chambers & MacMahon, 1994), and scatter-hoarding animals are an effective means of dispersal in arid and semiarid environments because they place large seeds in protective underground microsites.
Moreover, aqueous suspensions of nPM were cytotoxic to murine macrophages, possibly by generating reactive oxygen species abiotically (Xia et al.
They will not refill abiotically like some crackpots contend.
He added that the reactions that produce oil and gas abiotically inside the crust could occur in the mantle, meaning life may be thriving deeper yet.
Abiotically treated HDPE samples exposed to fungal stains showed greater reduction in tensile strength, breaking load and percentage of elongation compared to untreated HDPE (Fig 2, Fig 3 and Fig 4).
The remaining 10% was fixed abiotically, primarily by lightning [1, 2, 3].
However, recognition of these crystals as biosignatures requires careful assessment in order to differentiate them from abiotically produced crystals (Kopp and Kirshvink 2008).
