Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

UV and FIR selected star-forming galaxies at z=0: differences and overlaps

open access: yes, 2006
We study two samples of local galaxies, one is UV (GALEX) selected and the other FIR (IRAS) selected, to address the question whether UV and FIR surveys see the two sides ('bright' and 'dark') of the star formation of the same population of galaxies or ...

Spruce Budworm Egg Mass Density on Balsam Fir and White Spruce: Low Population Levels (Lepidoptera: Tortricidae) [PDF]

open access: yes, 2017
As part of a study to develop improved foliage sampling methods for spruce budworm, Choristoneura fumiferana (Clemens), egg masses, two balsam fir (four in one stand), Abies balsamea, and two white spruce, Picea glauca, trees were chosen from each of ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

PREDICCIÓN DEL CICLO SOLAR 23 CON UN ALGORITMO ADALINE BASADO EN FUNCIONES POTENCIALES DE BASE RADIAL

open access: yesAnales (Asociación Física Argentina), 2013
El uso de funciones potenciales permite la generalización a problemas no lineales de algoritmos de aprendizaje de naturaleza lineal. Dichas funciones, denominadas 'kernels', permiten mapear los datos originales a un espacio de alta dimensión (espacio de ...

Deep Herschel view of obscured star formation in the Bullet cluster [PDF]

open access: yes, 2010
We use deep, five band (100–500 μm) data from the Herschel Lensing Survey (HLS) to fully constrain the obscured star formation rate, SFR_(FIR), of galaxies in the Bullet cluster (z = 0.296), and a smaller background system (z = 0.35) in the same field.

Optical identification of ISO far-infrared sources in the Lockman Hole using a deep VLA 1.4 GHz continuum survey [PDF]

open access: yes, 2005
By exploiting the far-infrared(FIR) and radio correlation, we have performed the Likelihood-Ratio analysis to identify optical counterparts to the far-infrared sources in the Lockman Hole.

Entanglement in Fir: Thinking Matter in Peter Larkin’s “praying // firs \\ attenuate” [PDF]

open access: yesReligions, 2017
This article reads Peter Larkin’s poem “praying // firs \\ attenuate” (2014) as a way to think the divine in relation to the ecological as a mutual poetic giving. It suggests that the poem entangles the reader in a series of relational imaginings that complicates the modern commodification of the nonhuman and questions a secular fatigue with the divine.

A pipeline crisis or a sustainability crisis? Local and national succession planning for headteachers in England

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...
