Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

Integrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Testing Lorentz Invariance by Comparing Light Propagation in Vacuum and Matter

, 2010
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of a monolithic optical sapphire resonator with the resonance frequency of an orthogonal ...

Millimeter-wave surface impedance of optimally-doped Ba(Fe1-xCox)2As2 single crystals [PDF]

, 2013
Precision measurements of active and reactive components of in-plane microwave surface impedance were performed in single crystals of optimally-doped Fe-based superconductor Ba(Fe1-xCox)2As2 (x = 0.074, Tc = 22.8 K).

Impact of Forest Fragmentation and Associated Edge Effects on Tropical Forest Biodiversity in North West Madagascar, Assessed via Ecoacoustics

Animal Conservation, EarlyView.
Deforestation in the tropics is a major threat to forest‐specialist animals, many of which are already threatened with extinction. We assessed how forest fragmentation and its associated edge‐effects impact animal biodiversity in Northwest Madagascar using soundscape analysis and acoustic indices.

Well-dressed states for wave-packet dynamics in cavity QED [PDF]

, 1997
The quantization of atomic center-of-mass motion is considered within the context of cavity QED with particular emphasis on the dynamics of localized wave packets. “Well-dressed” states are introduced as an eigenbasis that incorporates both the quantized

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

Agricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Core-shell microdisk with InGaN/GaN quantum wells for dual-band whispering gallery mode lasing

Chip
The development of high-quality, stable, and cost-effective micro/nano dual-band lasing remains a crucial challenge for multifunctional applications. In this study, we demonstrated high-Q dual-band whispering gallery mode lasing in an independent core ...
