Social paper wasp ( Agelaia pallipes ) predates songbird nestling

, 2020
The social paper wasp Agelaia pallipes is known to eat carrion and scavenge on vertebrates. There are few records of wasps predating vertebrates, including an attack on an adult hummingbird and the predation of bird nestlings. During a project monitoring

Do paper wasps negotiate over helping effort? [PDF]

Behavioral Ecology, 2013
Recent theory and empirical studies of avian biparental systems suggest that animals resolve conflict over parental care via a process of behavioral negotiation or “rules for responding.” Less is known, however, about whether negotiation over helping effort occurs in cooperatively breeding animal societies or whether behavioral negotiation requires a ...

High-precision photometry by telescope defocussing. III. The transiting planetary system WASP-2 [PDF]

, 2010
We present high-precision photometry of three transits of the extrasolar planetary system WASP-2, obtained by defocussing the telescope, and achieving point-to-point scatters of between 0.42 and 0.73 mmag.

Structures, properties, and functions of the stings of honey bees and paper wasps: a comparative study

Biology Open, 2015
Through natural selection, many animal organs with similar functions have evolved different macroscopic morphologies and microscopic structures. Here, we comparatively investigate the structures, properties and functions of honey bee stings and paper ...

Estimation of Exoplanetary Planet-to-Star Radius Ratio with Homomorphic Processing

, 2017
In this paper a homomorphic filtering scheme is proposed to improve the estimation of the planet/star radius ratio in astronomical transit signals. The idea is to reduce the effect of the short-term earth atmosphere variations.

Unrelated Helpers in a Primitively Eusocial Wasp: Is Helping Tailored Towards Direct Fitness? [PDF]

, 2010
The paper wasp Polistes dominulus is unique among the social insects in that nearly one-third of co-foundresses are completely unrelated to the dominant individual whose offspring they help to rear and yet reproductive skew is high.

Predation of Chlorostilbon lucidus (Shaw, 1812) (Apodiformes: Trochilidae) hummingbird chicks by Polistes canadensis (Linnaeus, 1758) (Polistinae: Polistini): A new predatory interaction documented in the Brazilian Caatinga

Entomological Communications
Non-aggressive interactions between Neotropical social wasps (Vespidae) and birds frequently occur but remain poorly understood. Typically categorized as commensalism, where birds benefit while no advantages for the wasps have been documented, the ...

WASP-1: A lithium- and metal-rich star with an oversized planet

, 2007
In this paper we present our results of a comprehensive spectroscopicanalysis of WASP-1, the host star to the exoplanet WASP-1b. We derive T_eff = 6110 +/- 45 K, log g = 4.28 +/- 0.15, and [M/H] = 0.23 +/- 0.08, and also a high abundance of lithium, log ...

Phase curves of WASP-33b and HD 149026b and a New Correlation Between Phase Curve Offset and Irradiation Temperature [PDF]

, 2017
We present new 3.6 and 4.5 $\mu m$ Spitzer phase curves for the highly irradiated hot Jupiter WASP-33b and the unusually dense Saturn-mass planet HD 149026b.
