Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

open access: yesIntegrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider

open access: yesIntegrative Zoology, EarlyView.
The graphical abstract contrasts sex‐equivalent cognition (route‐planning & memory) with female‐biased nest architecture. Both sexes perform similarly in cognitive tests, but females build complex, geometry‐matching nests while males make simple shelters.

Five Principles for a New Economic Consensus

open access: yesGlobal Policy, EarlyView.
ABSTRACT This paper puts forward five principles for a new economic consensus, which could serve as a modern alternative to the Washington Consensus of 35 years ago. They are built on new ideas that have gained currency in economics over the past three decades. We also provide examples of the policies that could follow from these principles.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Sleep and the fruit fly

Trends in Neurosciences, 2001
The function of sleep remains a long-standing mystery in neurobiology. The presence of a sleep-like state has recently been demonstrated in the fruit fly, Drosophila melanogaster, meeting the essential behavioral criteria for sleep and also showing pharmacological and molecular correlates of mammalian sleep. This development opens up the possibility of

Pheromones in the Fruit Fly

2013
The identification of pheromones (chemical communication cues) is critical to our understanding of complex social behavior in insects and other animals. In this chapter, we describe analytical methods for the purification of lipid pheromones by thin layer chromatography and the quantification and determination of their elemental composition by mass ...

Fruit fly research in China

Journal of Genetics and Genomics, 2018
Served as a model organism over a century, fruit fly has significantly pushed forward the development of global scientific research, including in China. The high similarity in genomic features between fruit fly and human enables this tiny insect to benefit the biomedical studies of human diseases. In the past decades, Chinese biologists have used fruit

CITRUS FRUITS AND THE MEDITERRANEAN FRUIT FLY

Acta Horticulturae, 2015
The Mediterranean fruit fly (medfly), Ceratitis capitata (Diptera: Tephritidae) is considered one of the most important pests for citrus fruits. Recent and older studies demonstrate a variable degree of sensitivity of citrus species to medfly infestations.

Effect of Chemosterilants Against the Oriental Fruit Fly, Melon Fly, and Mediterranean Fruit Fly

Journal of Economic Entomology, 1965
In tests conducted in Hawaii from 1959 to 1964 both sexes of one or more of 3 species of tephritid flies were sterilized without toxic effects by treating food and water with tcpa, metepa, apholate, or tretamine, applying these materials topically to pupae or adults, or exposing adults to deposits of the chemosterilants.
