Pollinator-attracting semiochemicals of the wasp-flower Epipactis helleborine [PDF]

open access: yes, 2008
The orchid genus Epipactis is represented by 25 species in Europe (Richards 1982). Epipactis helleborine (L.) Crantz is the most common and widely distributed species of the genus (Wiefelspütz 1970), and is a prime example for wasp-flowers, because it is

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 ...

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 ...

Social Wasps on Eugenia uniflora Linnaeus (Myrtaceae) Plants in the Urban Area of Viçosa, Minas Gerais State, Brazil

open access: yesSociobiology, 2013
Social wasps (Hymenoptera: Vespidae) of the subfamily Polistinae, being biological pest control agents, can effectively participate in ongoing efforts to limit the use of chemical agents used in combating insect pests in urban forestry.

Don’t Spray the Wasps! Using \u3ci\u3ePolistes\u3c/i\u3e Paper Wasps for Pest Management in the Home Garden [PDF]

open access: yes, 2011
Pest control poses a challenge to all gardeners, especially those wishing to use organic practices. We examined the potential use of Polistes paper wasps as a bio-control agent in the organic backyard garden.

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

open access: yesCytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Task partitioning in insect societies. I. Effect of colony size on queueing delay and colony ergonomic efficiency [PDF]

open access: yes, 1999
The collection and handling of colony resources such as food, water, and nest construction material is often divided into subtasks in which the material is passed from one worker to another. This is known as task partitioning.
