A Note on the Depth-from-Defocus Mechanism of Jumping Spiders
Jumping spiders are capable of estimating the distance to their prey relying only on the information from one of their main eyes. Recently, it has been shown that jumping spiders perform this estimation based on image ...
Combining Chemical Information From Grass Pollen in Multimodal Characterization
The analysis of pollen chemical composition is important to many fields, including agriculture, plant physiology, ecology, allergology, and climate studies. Here, the potential of a combination of different spectroscopic ...
The Role of Urbanization in the Global Carbon Cycle
Urban areas account for more than 70% of CO2 emissions from burning fossil fuels. Urban expansion in tropics is responsible for 5% of the annual emissions from land use change. Here, I show that the effect of urbanization ...
Wood Cellular Dendroclimatology
Testing New Proxies in Great Basin Bristlecone Pine
Dendroclimatic proxies can be generated from the analysis of wood cellular structures, allowing for a more complete understanding of the physiological mechanisms that control the climatic response of tree species. Century-long ...
Peptide-Assisted Design of Precision Polymer Sequences
On the Relevance of the Side-Chain Sequences and the Variability of the Backbone
Functional sequences of monodisperse, sequence‐defined oligo(amide‐urethane)s are designed based on a peptide sequence as blueprint. The translation of a discrete side‐chain functionality sequence from a known peptide‐based ...
A simple MALDI target plate with channel design to improve detection sensitivity and reproducibility for quantitative analysis of biomolecules
Overcoming the detrimental effects of sweet spots during crystallization is an important step to improve the quantitative abilities of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry. In this study, ...
Spectroscopic Discrimination of Sorghum Silica Phytoliths
Grasses accumulate silicon in the form of silicic acid, which is precipitated as amorphous silica in microscopic particles termed phytoliths. These particles comprise a variety of morphologies according to the cell type ...
Novel Endocranial Data on the Early Therocephalian Lycosuchus vanderrieti Underpin High Character Variability in Early Theriodont Evolution
Therocephalia is one of the major therapsid clades and ranges from the middle Permian to Middle Triassic. The earliest therocephalians were large-bodied predators whose fossils are common in middle Permian rocks of South ...
Cobalt-Assisted Morphology and Assembly Control of Co-Doped ZnO Nanoparticles
The morphology of metal oxide nanostructures influences the response of the materials in a given application. In addition to changing the composition, doping can also modify the morphology of a host nanomaterial. Herein, ...
Improving Models of Species Ecological Niches: A Remote Sensing Overview
Effective conservation capable of mitigating global biodiversity declines require thorough knowledge on species distributions and their drivers. A species ecological niche determines its geographic distribution, and species ...
