The Dark Star of Baisun-tau: a history of cave exploration in Southern Uzbekistan, 1990–2013 [PDF]

open access: yes, 2014
Very little is known about the karst and caves in southern Uzbekistan, where some of the deepest caves in Asia have been discovered. In particular, the limestone plateau of the Baisun-tau mountain range has a tremendous potential for exploration.

Genotype‐by‐environment interaction informs selection for seed physiological quality and stink bug tolerance in soybean under pest management contrasts

open access: yesPest Management Science, EarlyView.
Genotype‐by‐environment interaction shaped soybean seed stability under contrasting insecticide regimes. Seed longevity emerged as a stable, management‐relevant trait under pest pressure. High‐pressure, no‐insecticide conditions improved discrimination of tolerant genotypes for integrated pest management deployment.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

open access: yesWildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Temporal community change in stream ecosystems varies by assemblage across US climates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Fertilization influences overyielding through dominance of species with high specific leaf area in young tree mixtures

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the context of anthropogenic eutrophication of the biosphere, understanding the impact of nutrient addition on plant diversity–productivity relationships remains a major challenge.

Climate Classification is an Important Factor in Assessing Quality-of-Care Across Hospitals

open access: yesScientific Reports, 2017
Climate is a known modulator of disease, but its impact on hospital performance metrics remains unstudied. We assess the relationship between Köppen-Geiger climate classification and hospital performance metrics, specifically 30-day mortality, as ...

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

open access: yesJournal of Animal Ecology, EarlyView.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

A Fairness Relation Based on the Asymmetric Choquet Integral and Its Application in Network Resource Allocation Problems

open access: yesJournal of Applied Mathematics, 2014
The recent problem of network resource allocation is studied where pairs of users could be in a favourable situation, given that the allocation scheme is refined by some add-on technology. The general question here is whether the additional effort can be
