Animal Behaviour, 2017 Birds often need to distinguish their own eggs from those of others or from other objects that could be confused with their eggs. Egg recognition occurs in a variety of birds that retrieve eggs displaced from the nest. Egg recognition and rejection is also a particularly widespread defence against brood parasites. We studied egg retrieval and rejection

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction
Advanced Science, EarlyView.During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Does Neuroticism Disrupt the Psychological Benefits of Nostalgia? A Meta‐analytic Test
European Journal of Personality, EarlyView., 2020 Abstract Nostalgia, a sentimental longing or wistful affection for the past, confers self‐oriented, existential, and social benefits. We examined whether nostalgic engagement is less beneficial for individuals who are high in neuroticism (i.e. emotionally unstable and prone to negative affect).

Relationships between egg-recognition and egg-ejection in a grasp-ejector species.
PLoS ONE, 2017 Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species. Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and ...

Egg recognition in Cinereous Tits (Parus cinereus): eggshell spots matter
Avian Research, 2019 Background Brood parasitic birds such as cuckoos (Cuculus spp.) can reduce their host’s reproductive success. Such selection pressure on the hosts has driven the evolution of defense behaviors such as egg rejection against cuckoo parasitism. Studies have

Light matters: Nest illumination alters egg rejection behavior in a cavity-nesting bird
Avian Research, 2022 Egg discrimination by cavity-nesting birds that build nests under dim light conditions was presumed to depend on nest luminance, although this hypothesis has rarely been tested.

Who moved my eggs? An experimental test of the egg arrangement hypothesis for the rejection of brood parasitic eggs [PDF]
Animal Cognition, 2014 Avian brood parasitism is an exceptional reproductive strategy whereby parasites reduce their own costs associated with parental care and impose them on the host parents. Consequently, host species have evolved multiple defensive mechanisms to combat parasitism. The vast majority of research attention to date has examined host defenses to recognize and

Advanced Science, EarlyView.Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Avian Research, 2019 Background Red-winged Blackbirds (Agelaius phoeniceus), hereafter red-wings, are much less frequently parasitized by Brown-headed Cowbirds (Molothrus ater) in eastern North America than in central North America and had not been recorded as hosts in our ...

Egg discrimination along a gradient of natural variation in eggshell coloration [PDF]
, 2017 Accurate recognition of salient cues is critical for adaptive responses, but the underlying sensory and cognitive processes are often poorly understood. For example, hosts of avian brood parasites have long been assumed to reject foreign eggs from their ...
