Polypiectropus species (Trichoptera: Polycentropodidae) from China : with consideration of their phylogeny [PDF]

open access: yes, 2011
Six species of the genus Polyplectropns are recorded from the People's Republic of China. All the species are new to science. A key to the males is given. The larva of Polyplectropns nanjingensis sp. nov. is illustrated.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Effects of Simultaneous Sitophilus zeamais and Prostephanus truncatus During Storage of Maize in Hermetic and Non‐Hermetic Conditions

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background Sitophilus zeamais (Mostschulsky), the maize weevil, and Prostephanus truncatus (Horn), the larger grain borer, are two notorious insect pests of farm‐stored products in Sub‐Saharan Africa (SSA). The goal of this study was to determine whether there were interactions between P. truncatus and S. zeamais during storage.

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

open access: yesChemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...
