Host‐plant sex and phenology of Buddleja cordata Kunth interact to influence arthropod communities [PDF]

Ecology and Evolution
Intraspecific variation in plants is expected to have profound impacts on the arthropod communities associated with them. Because sexual dimorphism in plants is expected to provide consistent variation among individuals of the same species, researchers ...

Seed Thermal Response, and Morphological and Biochemical Plasticity in <i>Wigandia urens</i> as Indicators of Its Utility for Elevational and Latitudinal Assisted Migration. [PDF]

Ecol Evol
To identify the phenotypic plasticity in germination traits related to the tolerance to changes in temperature resulting from CC and improve the successful of plant cover recovery in elevational and latitudinal gradients, we assessed the amplitude and variability of phenotypic plasticity in the seed response of W.

Identification of preferred hTBP DNA binding sites by the combinatorial method REPSA [PDF]

Nucleic Acids Research, 1997
Here we describe the application of a novel combinatorial method, restriction endonuclease protection selection and amplification (REPSA), to identification of a consensus DNA binding site for the TATA binding subunit (hTBP) of the human general transcription factor TFIID.

Impacts of Drying and Rewetting on the Radiocarbon Signature of Respired CO2 and Implications for Incubating Archived Soils

Journal of Geophysical Research: Biogeosciences, Volume 126, Issue 9, September 2021., 2021
Abstract The radiocarbon signature of respired CO2 (∆14C‐CO2) measured in laboratory soil incubations integrates contributions from soil carbon pools with a wide range of ages, making it a powerful model constraint. Incubating archived soils enriched by “bomb‐C” from mid‐20th century nuclear weapons testing would be even more powerful as it would ...

Logarithmic Coefficient Bounds and Coefficient Conjectures for Classes Associated with Convex Functions

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
It is well‐known that the logarithmic coefficients play an important role in the development of the theory of univalent functions. If S denotes the class of functions fz=z+∑n=2∞anzn analytic and univalent in the open unit disk U, then the logarithmic coefficients γn(f) of the function f∈S are defined by logfz/z=2∑n=1∞γnfzn.
