Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

The common cuckoo is an effective indicator of high bird species richness in Asia and Europe

Scientific Reports, 2017
Common cuckoo Cuculus canorus is a charismatic bird species with a dominant presence in human culture: from folklore legends to nowadays there is evidence of cuckoos being a prime candidate as a surrogate of bird diversity.

Great spotted cuckoo fledglings often receive feedings from other magpie adults than their foster parents: which magpies accept to feed foreign cuckoo fledglings?

PLoS ONE, 2014
Natural selection penalizes individuals that provide costly parental care to non-relatives. However, feedings to brood-parasitic fledglings by individuals other than their foster parents, although anecdotic, have been commonly observed, also in the great

Food‐solicitation displays in nestling birds: still begging for answers

Biological Reviews, EarlyView.
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.

Application of improved cuckoo algorithm in water quality sensor deployment

Dianzi Jishu Yingyong, 2020
Aiming at the problem of uneven distribution of traditional wireless sensor networks, the optimization process of the cuckoo algorithm was improved based on Adam optimization algorithm, and the elimination probability of the cuckoo algorithm was improved

Coupled ethanol–trehalose processing accelerates thawing of rapid‐frozen cooked rice through water‐state modulation

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Freezing preserves cooked rice, but ice formation and water redistribution can cause structural and textural deterioration. The individual and combined effects of ethanol soaking and trehalose‐assisted cooking on freeze–thaw behaviour, water state, texture, and microstructure were investigated. Rice was soaked in water or an aqueous

A fuzzy adaptive controller for cuckoo search algorithm in active suspension system

Journal of Low Frequency Noise, Vibration and Active Control, 2020
This paper presents a fuzzy adaptive cuckoo search algorithm to improve the cuckoo search algorithm, which may easily fall into a local optimum when handling multiobjective optimization problems.
