Foraging innovation in the guppy [PDF]

Animal Behaviour, 1999
When novel behaviour patterns spread through animal populations, typically one animal will initiate the diffusion. It is not known whether such 'innovators' are particularly creative individuals, individuals exposed to the appropriate environmental contingencies, or individuals in a particular motivational state.

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

Advanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...

A difference between sexes: temporal variation in the diet of Carollia perspicillata (Chiroptera, Phyllostomidae) at the Macaregua cave, Santander (Colombia)

Animal Biodiversity and Conservation, 2020
Organisms adjust their foraging strategies to optimize the energetic costs during foraging with respect to benefits gained. These strategies are usually different in males and females due to their specific requirements during reproduction.

Urban Foraging: A Ubiquitous Human Practice Overlooked by Urban Planners, Policy, and Research

, 2017
Although hardly noticed or formally recognised, urban foraging by humans probably occurs in all urban settings around the world. We draw from research in India, South Africa, Sweden, and the United States to demonstrate the ubiquity and varied nature of ...

Graphitized Biochar Derived from Agricultural Wastes Enhances Methanogenesis via Conductivity‐Driven Direct Interspecies Electron Transfer

Advanced Science, EarlyView.
This work clarifies how feedstocks and their structural features promote methanogenesis, and identifies the key regulatory factors, reducing pollution to the global environment, and also helps to alleviate the energy crisis. This is the first study to systematically link feedstock lignin content, pyrolysis conditions, biochar graphitization, and DIET ...

Hog badger (Arctonyx collaris) latrine use in relation to food abundance: evidence of the scarce factor paradox

Ecosphere, 2015
Many carnivores use latrines, and investigations of latrine use have typically been concerned with territorial defense, often at the expense of fully evaluating other, not mutually exclusive, functions.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Urban gardens promote bee foraging over natural habitats and plantations

Ecology and Evolution, 2016
Increasing human land use for agriculture and housing leads to the loss of natural habitat and to widespread declines in wild bees. Bee foraging dynamics and fitness depend on the availability of resources in the surrounding landscape, but how precisely ...
