Abstract Despite the ecological significance of desert springs, little is known about relationships between spring hydrogeochemistry and ecology, particularly over multiple trophic levels. Here, we surveyed microbial communities (bacteria and archaea

The presence and mobility of metal-rich sulfides in lower crustal magma chambers can act as a gateway for metals to be trapped, or released into ascending magmas that are then able to form upper crustal porphyry copper and gold deposits.

Magmatic Ni-Cu-platinum group element (PGE) deposits are commonly located in tectonically active regions that typically undergo significant deformation and metamorphism and subsequent reworking of sulfide. The Munali Ni deposit is hosted by a dynamic

Laser-induced breakdown spectroscopy (LIBS) is a form of optical emission spectroscopy that can be used for the rapid analysis of geological materials in the field under ambient environmental conditions. We describe here the innovative use of handhel

The objective of this paper was to test the hypothesis that growth and soil moisture would increase after heavy thinning in seven years old oak-hornbeam coppice stand. Effects of thinning on (i) diameter and height increment of the remaining sprouts

Tuff beds (volcanic ash beds and tuffs) have been known in the Miocene Monterey and Modelo Formations since they were initially described nearly 100 yr ago. Yet, these tephra layers have remained largely ignored. The ages and correlation of the Monte

Based on yield tables for oak high forest and oak coppice (both first site class) and using assortment tables and assortment prices in the Czech Republic in 2009, a set of variants of conversion of high forest to coppice was simulated. Average annual
