A Market-Based Approach to Manage Endangered Species Interactions [PDF]

An economic activity interacts with an endangered species. The activity can be divided into mutually exclusive strata with different levels of interaction. Observing the activity in order to monitor interactions is costly.

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

A Real Option Approach to the Protection of a Habitat Dependent Endangered Species [PDF]

We use a real option approach to determine optimally when a social planner has to stop or resume logging in situations where an endangered species relies on forest habitat for its survival, and that habitat evolves stochastically.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

A research toolbox for regional data collection to support the conservation of large batoids: A case study on the critically endangered flapper skate (Dipturus intermedius)

Conservation Science and Practice
Elasmobranchs, specifically skate species (superorder Batoidea), are at risk of extinction, with over one‐third currently listed as Endangered, exacerbated due to their k‐selected life strategy. A regional conservation approach is required to support the

Wildlife trade and endangered species protection [PDF]

Markets for endangered species potentially generate incentives for both legal supply and poaching. To deter poaching, governments can spend on enforcement or increase legal harvesting to reduce the return from poaching.

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Low Heterozygosity and Historical Bottleneck Effect Depicted From the Genome Assembly of the Indus River Dolphin (Platanista minor)

Ecology and Evolution
The Indus River dolphin (Platanista minor) is a highly endangered freshwater dolphin endemic to the Indus River system of the Indian subcontinent. We reported a de novo assembly and characterization of the draft genome of the Indus River dolphin by using
