An operational definition of the biome for global change research
(Wiley Online, 2020)Biomes are constructs for organising knowledge on the structure and functioning of the world’s ecosystems, and serve as useful units for monitoring how the biosphere responds to anthropogenic drivers, including climate ... -
On the minimal Hamming weight of a multi-base representation
(Elsevier, 2020)Given a finite set of bases b1, b2, ..., br (integers greater than 1), a multi-base representation of an integer n is a sum with summands dbα1 1 b α2 2 ··· bαr r , where the αj are nonnegative integers and the digits ... -
Light-driven proton transfer for cyclic and temporal switching of enzymatic nanoreactors
(Wiley Online, 2020-08)Temporal activation of biological processes by visible light and subsequent return to an inactive state in the absence of light is an essential characteristic of photoreceptor cells. Inspired by these phenomena, light-responsive ... -
Educating the enemy : harnessing learned avoidance behavior in wild predators to increase survival of reintroduced southern corroboree frogs
(Wiley, 2019)After decades of near-complete extirpation, the yellow-and-black-striped Southern Corroboree Frog (Pseudophryne corroboree) is being reintroduced into field enclosures that exclude all but avian predators. The frog's long ... -
Tracking lubricants during single screw extrusion of uPVC
(Elsevier, 2020-04-02)Lubrication is one of the most important parameters in unplasticized polyvinyl chloride (uPVC) processing apart from the PVC resin and processing equipment. Lubricants are used in specific ratios to ensure effective fusion ... -
Volume is related to surface-area-to-volume across Centrobolus Cook, 1897 species
(UIJIR, 2022-11)In this paper I test for a relationship between volume (size) and surface-area-to-volume ratios in red millipedes Centrobolus Cook, 1897. Volume was not related to surface-area-to-volume ratios in males (r=-0.28357370, Z ... -
Sex ratio varies with average temperature in red millipedes Centrobolus Cook, 1897
(IJESIRD, 2022-12)In this paper, I check for correlations between the sex ratio for males and females and average temperature in red millipedes Centrobolus Cook, 1897. I found correlations between sex ratio and average temperature (r=-0.68, ... -
Sex ratio varies with minimum temperature in red millipedes Centrobolus Cook, 1897
(IJESIRD, 2022-12)In this paper, I check for correlations between the sex ratio for males and females and minimum temperature in red millipedes Centrobolus Cook, 1897. I found correlations between sex ratio and minimum temperature (r=-0.68, ... -
Sex ratio varies with maximum temperature in red millipedes Centrobolus Cook, 1897
(IJESIRD, 2022-12)In this paper, I check for correlations between the sex ratio for males and females and maximum temperature in red millipedes Centrobolus Cook, 1897. I found correlations between sex ratio and maximum temperature r=-0.68, ... -
Sex ratio varies with precipitation in red millipedes Centrobolus Cook, 1897
(IJESIRD, 2022-12)In this paper, I check for correlations between the sex ratio for males and females and precipitation in red millipedes Centrobolus Cook, 1897. I found correlations between sex ratio and precipitation (r=-0.68, Z ... -
Sex ratio varies with humidity in red millipedes Centrobolus Cook, 1897
(IJESIRD, 2022-12)In this paper, I check for correlations between the sex ratio for males and females and humidity in red millipedes Centrobolus Cook, 1897. I found correlations between sex ratio and humidity (r=-0.68, Z score=-1.87, n=8, ... -

Is mass correlated with length among red millipedes Centrobolus Cook, 1897?
(Munis Entomology & Zoology., 2023-01)Body mass variation was correlated with male and female length in the red millipede genus Centrobolus. Mass and length (r=0.86, Z score=2.87, n=8, p<0.01) in males (r=0.97, Z score=2.99, n=5, p<0.01) and females (r=0.96, ... -
The highest daily hours of sunshine are related to longitude across the distribution of pill millipedes Sphaerotherıum Brandt, 1833.
(Munis Entomology & Zoology., 2023-01)The objectives of this study were to determine what happened when Sexual Size Dimorphism (SSD) and body size changed with an eco-geographical factor. The highest daily hours of sunshine were correlated with latitude and ... -
