Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Honey bee visitation to sunflower: effects on pollination and plant genotype

Scientia Agricola, 2011
Sunflower (Helianthus annuus L.) is an allogamic plant, which needs insects on flowering, especially the honeybees for seed production. Collecting nectar and pollen by honeybees in agricultural crops is essential to apiculture, as well as a better ...

Venom production by Africanized honeybees (Apis mellifera) and Africanized-European hybrids

Journal of Venomous Animals and Toxins, 2001
This study used 15 beehives: five with Africanized queens sisters (Apis mellifera), five with Italian queens sisters (Apis mellifera ligustica), and five with Carniolan queens sisters (Apis mellifera carnica). The queens were fertilized naturally. This experiment was performed in the apiary of the Botucatu School of Veterinary Medicine and Animal ...

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

People and Nature, EarlyView.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

Honey bee attractants and pollination in sweet orange, Citrus sinensis (L.) Osbeck, var. Pera-Rio

Journal of Venomous Animals and Toxins including Tropical Diseases, 2004
This experiment studied the frequency and behavior of insects on sweet orange flowers, Citrus sinensis (L.) Osbeck, their effect on fruit production (quantity and quality), nectar and pollen collection, and the effectiveness of different attractants ...

Mitochondrial DNA variability in South African honeybees (Apis mellifera L) [PDF]

Apidologie, 1994
L'ADN mitochondrial (ADNmt) de l'abeille se caracterise par une variabilite de longueur entre les genes codant pour l'ARN de transfert de la leucine (ARNt-Leu) et la cytochromoxydase II. Un court fragment P de 54 paires de bases et une ou plusieurs repetitions de la sequence Q, constituee de 196 paires de bases, est caracteristique de cette region d ...

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

African bush elephants respond to a honeybee alarm pheromone blend [PDF]

Current Biology, 2018
We here report the responses of African bush elephants (Loxodonta africana) to a crude approximation of the honeybee alarm pheromone blend. We show that the elephants had an avoidance response to the semiochemical blend. The use of honeybee alarm pheromones to manage elephant movements in a non-invasive manner, using natural cues to which elephants may

Making Learning Personally Relevant: Sensemaking Assets Used in Families' Discussions While Using a Pollinator‐Focused Mobile Augmented Reality App

Science Education, EarlyView.
ABSTRACT This study seeks to better understand the unique sensemaking assets that rural families weave into their outdoor learning experience while using a location‐based mobile app focused on healthy habitats for solitary bees. The project included mobile augmented reality (AR) technologies, which are increasingly used as educational tools at informal

Ecophysiology of an Avian Invader: Body Condition and Metabolic Rate Adjustments to Ambient Temperature

Integrative Zoology, EarlyView.
This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In
