YOLO-Based Deep Learning Framework for Olive Fruit Fly Detection and Counting

open access: yesIEEE Access, 2021
The olive fruit fly can damage up to 100% of the harvested fruit and can cause up to 80% reduction of the value of the resulting olive oil. Therefore, it is important to early detect its presence in the olive orchard to take the appropriate

Cluster formation and anomalous fundamental diagram in an ant trail model [PDF]

open access: yes, 2002
A recently proposed stochastic cellular automaton model ({\it J. Phys. A 35, L573 (2002)}), motivated by the motions of ants in a trail, is investigated in detail in this paper.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Concise Syntheses of Insect Pheromones Using Z-Selective Cross Metathesis [PDF]

open access: yes, 2013
The use of insect sex pheromones to limit specifically targeted pest populations has gained increasing popularity as a viable, safe, and environmentally friendly alternative to insecticides. While broad-spectrum insecticides are toxic compounds that have

Apitoxin harvest affects population development but not the hygienic behavior of African-derived honey bees

open access: yesSociobiology, 2016
The biological properties of apitoxin have prompted its production for use in human and animal health applications. However, the apitoxin harvest triggers a defense reaction in honeybee colonies, which includes the release of alarm pheromones (isopentyl ...

Environmentally vulnerable noble chafers exhibit unusual pheromone-mediated behaviour. [PDF]

open access: yesPLoS ONE, 2018
Conserving populations of environmentally vulnerable insect species requires a greater understanding of the factors that determine their abundance and distribution, which requires detailed knowledge of their population and community ecology.

Sex and the nose: human pheromonal responses [PDF]

open access: yesJournal of the Royal Society of Medicine, 2007
The chemosensory functions of the human nose are underappreciated. Traditional teaching is that the sense of smell detects volatile compounds, which may then allow the identification of substances that may be beneficial or harmful—such as good versus putrefied food.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...
