“…A significant reduction of fungal colony with increasing toxicity was seen in different studies [38]. Different element like Na, Mg, Al, Si, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu and Zn were the major component in the dust deposition [11]. This deposit above a specific range turned into toxic substance and hampered the colonization of microbes.…”

“…As a result of interest in the removal of atmospheric particles by trees in urban areas, several studies have looked at the particle capture efficiency of trees (Beckett et al, 2000a;Freer-Smith et al, 2004;Ram et al, 2012;Räsänen et al, 2013). In particular, Ram et al (2012) suggested that the particle capture efficiency of a conically shaped crown differs from that of a rounded crown, based on their field experiments.…”

“…In particular, Ram et al (2012) suggested that the particle capture efficiency of a conically shaped crown differs from that of a rounded crown, based on their field experiments. They found that particle capture efficiency of a rounded crown was higher than that of a conically shaped crown and suggested that the difference in particle capture efficiency between those crowns might depend on the number of trichomes and stomata on the leaves (Ram et al, 2012). On the other hand, Beckett et al (2000a) found that conifers could capture more aerosol particles than broad-leaved tree species in the field.…”

“…Also, there is a lot of research about the effect of aerosols on trees grown in polluted urban areas (e.g., Sase et al, 1998;Tomašević et al, 2005). Trees in urban areas are expected to remove air pollutants from the atmosphere and function as biological indicators (Beckett et al 2000a;Ram et al, 2012). Compared to these experiments, little information on the effect of transported aerosols on forest trees in the field is available.…”

In determining the effect of aerosols on forest trees, it is necessary to estimate the deposition of aerosols to forests. To this end we must consider the arboreal factors that influence the deposition of aerosols on forest trees. This paper examines such relevant factors as canopy shape, shoot structure, and leaf surface structures. Laboratory and field experiments in urban areas show that these factors play an important role in the deposition of aerosols on trees. SEM-EDX analyses have determined the chemical composition of particles deposited on the surfaces of tree leaves in urban areas. In forests, however, details of aerosol particles deposited on leaf surfaces is not known, and the effect of abiotic factors such as rainfall, fog and wind has not been determined. Further information is needed, including experimental data about the aerosols deposited on leaf surfaces of trees in a forest, taking into account canopy shape, leaf surface structures and tree phenology.

Evolutionary Anthropology

Grit is implicated in several biological phenomena—it wears teeth, it fractures teeth, it drives tooth evolution, it elicits complex manual manipulations—any one of which could be described as a central topic in evolutionary anthropology. But what is grit? We hardly know because we tend to privilege the consequences of grit (it is abrasive) over its formal features, all but ignoring crucial variables such as mineral composition, material properties, and particle geometry (size, angularity), not to mention natural variation in the habitats of primates and their food surfaces. Few topics have animated so much debate and invited such cool indifference at the same time. Our goal here is to shine a light on grit, to put a philosophical lens on the nature of our discourse, and to call attention to large empirical voids that should be filled and folded into our understanding of primate natural history and evolution.
