Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, EarlyView.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

Landscape Heterogeneity and Changing Bioclimatic Parameters Link to Potential Expansion of Gazalina chrysolopha (Lepidoptera; Notodontidae) in Nepal: A Possible Bioagent for Seasonal Hyperacute Panuveitis (SHAPU) in South Asia

Ecology and Evolution
Seasonal hyperacute panuveitis (SHAPU) is an eye disease primarily reported in Nepal, especially in mid‐hill regions of central and western parts. Several clinical and entomological studies have identified Gazalina chrysolopha as the possible causative ...

Regulatory role of PBAN in sex pheromone biosynthesis of heliothine moths

Frontiers in Endocrinology, 2011
Both males and females of heliothine moths utilize sex pheromones during the mating process. Females produce and release a sex pheromone for the long-range attraction of males for mating.

Responses of generalist invertebrate predators to pupal densities of autumnal and winter moths under field conditions

, 2013
1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely ...

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

PLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

Responsiveness to Sugar Solutions in the Moth Agrotis ipsilon: Parameters Affecting Proboscis Extension

Frontiers in Physiology, 2019
Adult moths need energy and nutrients for reproducing and obtain them mainly by consuming flower nectar (a solution of sugars and other compounds). Gustatory perception gives them information on the plants they feed on.

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

PLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Moths behaving like butterflies. Evolutionary loss of long range attractant pheromones in Castniid Moths: A Paysandisia archon model

, 2012
Background: In the course of evolution butterflies and moths developed two different reproductive behaviors. Whereas butterflies rely on visual stimuli for mate location, moths use the"female calling plus male seduction" system, in which females release ...

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
