Nordic Journal of Botany, EarlyView.Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Hydraulic Behavior of Karst Aquifers
Water, 2019 The objective of this Special Issue, “Hydraulic Behavior of Karst Aquifers”, is to focus on recent advances in karst hydrogeology in different areas of the world, focusing on topics dealing with the peculiar characteristics of karst aquifers. In particular, thirteen peer-reviewed articles were collected, focusing on hydraulic aspects and their ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Karst Aquifers Vulnerability or Sensitivity?
Acta Carsologica, 2016 Za določitev vodovarstvenih območij ter za načrtovanje rabe prostora v zaledju zajetih kraških izvirov in vrtin se praviloma uporablja koncept kartiranja ranljivosti kraških vodonosnikov. Obstaja več med seboj različnih metodologij kartiranja ranljivosti kraških vodonosnikov in pregled znanstvene literature kaže na določene razlike v definiciji pojma ...

Plant Biology, EarlyView.Root water uptake strategies vary among temperate tree species (European beech, Douglas fir, and Norway spruce), with beech–conifer mixtures altering water uptake depths, while site conditions and temporal dynamics further shape the contribution of different soil depths to water supply.

Water and Environment Journal, EarlyView.Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

Parametric identification of a karst aquifer [PDF]
WIT Transactions on Ecology and the Environment, Vol 99, 2006 The parametric identification of non-homogeneous aquifers is a highly complex task because it requires the performance of a large number of infield trials, which often yield results that are difficult to interpret or have doubtful reliability. Moreover, the physically continuous nature of the hydrogeological parameters to be identified (typically ...
