Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

open access: yesThe FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

Cálculo convencional de estructuras, teoría: estructuras articuladas

open access: yes, 1986
El objetivo de esta publicación es desarrollar la fase segunda dentro del proceso de un cálculo estructural, que se designa con el nombre de cálculo de estructuras. Si bien existen muchos e importantes problemas que pueden ser incluidos dentro de este ámbito, aquí únicamente serán tratados aquellos que son específicos del análisis, es decir, los ...

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

open access: yesNew Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Key sources of uncertainty in process‐based modeling of live fuel moisture content

open access: yesNew Phytologist, EarlyView.
Location of the selected live fuel moisture content (LFMC) sampling sites. Summary Process‐based models that mechanistically represent water‐carbon balances in the atmosphere‐soil–plant continuum are an attractive tool for monitoring live fuel moisture content (LFMC) dynamics, a key variable when assessing fire danger.

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

open access: yesNew Phytologist, EarlyView.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Alucinación y estructura de la enunciación

open access: yes, 1996
La noción de cadena significante permite a J. Lacan precisar la estructura de la alucinación en su vinculación con la implicación subjetiva, cuestionando la clásica definición de la alucinación como percepción sin objeto. Es en este contexto que adquiere

Eco‐evolutionary context modifies a destructive plant invader's response to climate

open access: yesNew Phytologist, EarlyView.
Abiotic environment–fitness relationships can be shaped by evolutionary, ecological, and eco‐evolutionary contexts. Summary Understanding the relationship between climate and fitness will be important when predicting how plant populations respond to climate change. We conducted a replicated common garden experiment (4 sites × 2 yr) with 96 genotypes (n
