Explaining local-scale species distributions: relative contributions of spatial autocorrelation and landscape heterogeneity for an avian assemblage. [PDF]

open access: yesPLoS ONE, 2013
Understanding interactions between mobile species distributions and landcover characteristics remains an outstanding challenge in ecology. Multiple factors could explain species distributions including endogenous evolutionary traits leading to ...

River water temperature quantiles as thermal stress indicators: Case study in Switzerland

open access: yesEcological Indicators, 2021
The variability of the river water thermal regime has important consequences on the environment and aquatic habitat. In 25 independent and identically distributed stations in Switzerland, local frequency analysis is used to quantify extreme river ...

Superconductor strip with transport current: Magneto-optical study of current distribution and its relaxation [PDF]

open access: yes, 2001
The dynamics of magnetic flux distributions across a YBaCuO strip carrying transport current is measured using magneto-optical imaging at 20 K. The current is applied in pulses of 40-5000 ms duration and magnitude close to the critical one, 5.5 A. During

Investigating the Contact Responses of the Roller Cavity Surfaces in the Compressor Blade Rolling Process

open access: yesAdvances in Materials Science and Engineering, 2020
The investigation of the contact responses is the key for evaluating the local wear of dies in the plastic forming process. This paper investigated the contact load distributions and evolutions of the roller cavities in the compressor blade rolling ...

Study of Multiparticle Spikes in Central 4.5A GeV/c C-Cu Collisions

open access: yes, 1998
An analysis of local fluctuations, or spikes, is performed for charged particles produced in central C-Cu collisions at 4.5 GeV/$c$/nucleon. The distributions of spike-centers and the maximum density distributions are investigated for different narrow ...

Local pore size correlations determine flow distributions in porous media

open access: yes, 2017
The relationship between the microstructure of a porous medium and the observed flow distribution is still a puzzle. We resolve it with an analytical model, where the local correlations between adjacent pores, which determine the distribution of flows ...

Statistics of selectively neutral genetic variation

open access: yes, 2001
Random models of evolution are instrumental in extracting rates of microscopic evolutionary mechanisms from empirical observations on genetic variation in genome sequences.

Regional distribution shifts help explain local changes in wintering raptor abundance: implications for interpreting population trends. [PDF]

open access: yesPLoS ONE, 2014
Studies of multiple taxa across broad-scales suggest that species distributions are shifting poleward in response to global climate change. Recognizing the influence of distribution shifts on population indices will be an important part of interpreting ...
