Insectivorous birds eavesdrop on the pheromones of their prey

open access: yesPLOS ONE, 2018
Chemical cues play a fundamental role in mate attraction and mate choice. Lepidopteran females, such as the winter moth (Operophtera brumata), emit pheromones to attract males in the reproductive period. However, these chemical cues could also be eavesdropped by predators.

Using microstructures and composition to decipher the alterations of rodent teeth in modern regurgitation pellets—a good news-bad news story

open access: yes, 2020
Rodent accumulations are widely used for palaeoenvironmental reconstructions. But these accumulations are created through the activity of predators (carnivorous mammals, birds of prey), the predation and digestion of which modify the preservation of ...

An Aptamer‐Based EXACT Anticoagulant as a Sustainable, Animal‐Free Alternative to Unfractionated Heparin

open access: yesAdvanced Science, EarlyView.
By simply conjugating thrombin's active‐site inhibitor, dabigatran, with an exosite inhibitor, aptamer HD1, the resulting EXosite‐ACTive site (EXACT) inhibitors show two orders of magnitude higher potency and selectivity via synergistic binding, while maintaining the aptamer's antidote‐reversible trait, yielding a potential substitute for the animal ...

Robird: A Robotic Bird of Prey

open access: yesIEEE Robotics & Automation Magazine, 2017
Ever since the start of aviation, birds and airplanes have posed a mutual risk: Birds are killed when struck by aircraft, but, in return, bird strikes cause billions in damage to the aviation industry. Airports employ bird-control methods such as audiovisual deterrents (like scarecrows, lasers, and noise), weapons, and chemicals to relocate, suffocate,

Habitat selection and reproduction of red-backed shrikes (Lanius collurio) in relation to abundance of potential avian nest predators [PDF]

open access: yes, 2010
Many studies of farmland bird species have related abundance of species to different habitat variables, whereas few studies have incorporated the effects of predation on habitat selection. However, it is generally assumed that prey species select habitat

Sex-biased parental care and sexual size dimorphism in a provisioning arthropod [PDF]

open access: yes, 2015
The diverse selection pressures driving the evolution of sexual size dimorphism (SSD) have long been debated. While the balance between fecundity selection and sexual selection has received much attention, explanations based on sex-specific ecology have ...

A Floating‐Gate Photoelectric Synaptic Transistor Utilizing BP/POx/WSe2 Heterostructure for Neuromorphic Visual Processing

open access: yesAdvanced Science, EarlyView.
In this paper, a novel floating gate transistor (BP/POx/WSe2) is developed, which enables rich synaptic functionality under optoelectronic conditions and can mimic human visual memory. By introducing a two‐path convolutional neural network that synergistically fuses optical and electronic inputs, it can achieve efficient feature extraction and weight ...

A Multifunctional Molecular Probe for Multimodal Imaging‐Guided Potent Photothermal/Photodynamic Therapy of Endometriosis

open access: yesAdvanced Science, EarlyView.
The cRGD‐ILD molecular probe integrates clinically available components: a cRGD peptide (integrin αvβ3 targeting), ICG (for fluorescence/photoacoustic imaging and phototherapy), and Gd‐DTPA (MRI contrast). Utilizing small size and receptor targeting, it achieves selective lesion accumulation.
