Loss, persistence and reversal of phenotypic traits
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Morphological specialization influences nectar extraction efficiency of sympatric nectar-feeding bats [PDF]
SummaryMammals frequently use nectar as a supplementary food, while a predominantly nectarivorous lifestyle with morphological specializations for this feeding mode is rare within the class. However, Neotropical flower-visiting bats largely depend on nectar resources and show distinct adaptations to a nectar diet.

The review critically evaluated and compared the selected superfruit phytochemistry, their bioactive composition and the key health benefits majorly emphasizing the antioxidant potential. It has highlighted the translational challenges in formulating functional foods by addressing the issues related to delivery system, bioavailability mechanism and the

Thermal inactivation of Byssochlamys nivea in pineapple nectar combined with preliminary high pressure treatments [PDF]
Byssochlamys nivea is a thermal resistant filamentous fungi and potential micotoxin producer. Recent studies have verified the presence of ascospores of such microorganism in samples of pineapple nectars.

Of hummingbirds and helicopters: Hovering costs, competitive ability, and foraging strategies [PDF]
Wing morphology and flight kinematics profoundly influence foraging costs and the overall behavioral ecology of hummingbirds. By analogy with helicopters, previous energetic studies have applied the momentum theory of aircraft propellers to estimate ...

Soft Lithography Using Nectar Droplets [PDF]
In spite of significant advances in replication technologies, methods to produce well-defined three dimensional structures are still at its infancy. Such a limitation would be evident if we were to produce a large array of simple and, especially, compound convex lenses, also guaranteeing that their surfaces would be molecularly smooth.

The olfactory basis of orchid pollination by mosquitoes. [PDF]
Mosquitoes are important vectors of disease and require sources of carbohydrates for reproduction and survival. Unlike host-related behaviors of mosquitoes, comparatively less is understood about the mechanisms involved in nectar-feeding decisions, or ...

Distasteful Nectar Deters Floral Robbery [PDF]
Toxic nectar is an ecological paradox [1, 2]. Plants divert substantial resources to produce nectar that attracts pollinators [3], but toxins in this reward could disrupt the mutualism and reduce plant fitness [4]. Alternatively, such compounds could protect nectar from robbers [2], provided that they do not significantly alter pollinator visitation to

ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.
