How diverse are the mountain karst forests of Mexico?
Tropical forests on karstic relief (tropical karst forest) are among the most species-rich biomes. These forests play pivotal roles as global climate regulators and for human wellbeing. Their long-term conservation could be central to global climate mitigation and biodiversity conservation. In Mexico, karst landscapes occupy 20% of the total land surface and are …

Elevated Mercury Deposition, Accumulation, and Migration in a Karst Forest
The karst forest is one of the extremely sensitive and fragile ecosystems in southwest China, where the biogeochemical cycling of mercury (Hg) is largely unknown. In this study, we investigated the litterfall deposition, accumulation, and soil migration of Hg in an evergreen-deciduous broadleaf karst forest using high-resolution sampling and stable isotope …

Effects of density dependence in an evergreen-deciduous broadleaf karst
There is increasing evidence that density dependence is an important mechanism for the coexistence of species in natural forest communities. Although density dependence among neighbors has been widely studied in tropical, subtropical, and temperate forests, the effects thereof remain poorly understood for non-zonal forest types (e.g., karst forests).

Epigene and Hypogene Karst
In karst science, the term caprock is often used to describe non-carbonate strata that overlie a cave and that may collapse into a cave to form a "caprock collapse sinkhole" (Williams 2004). For example, in karst systems in Kentucky and Tennessee, beds of quartz sandstone (caprock) may overlie and form part of the roof a cave.
