An evaluation of pollination methods for strawberries cultivated in plant factories: robot vs hand

open access: yesTechnology in Horticulture, 2023
The cultivation of strawberries in plant factories with artificial lighting (PFAL) has recently been recognized as it makes pesticide-free and stable year-round production possible.

The Pollination of Toadflax [PDF]

open access: yesNature, 1916
Linaria spuria, Miller, is a not uncommon weed of cornfields on calcareous soils in the Midlands and south of England, in western, central, and southern Europe, in, northern Africa, and in western Asia, and it occurs adventitiously in North America. I have never observed insects pollinating the flower.

Testing Pollination Syndromes in Oenothera (Onagraceae)

open access: yesJournal of Pollination Ecology, 2021
Pollinators are considered a major selective force in shaping the diversification of angiosperms. It has been hypothesized that convergent evolution of floral form has resulted in “pollination syndromes” - i.e.

Pollinator conservation—the difference between managing for pollination services and preserving pollinator diversity

open access: yesCurrent Opinion in Insect Science, 2015
Our review looks at pollinator conservation and highlights the differences in approach between managing for pollination services and preserving pollinator diversity. We argue that ecosystem service management does not equal biodiversity conservation, and that maintaining species diversity is crucial in providing ecosystem resilience in the face of ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

The Pollination of the Olive [PDF]

open access: yesNature, 1908
As Knuth's great work on flower pollination, compiled from all available sources, says nothing whatever about the olive, I recently asked Prof. J. E. Coit, of Arizona, to look out for insects upon the flowers. He carefully examined many olive trees in flower at Tucson, and did not find a single insect at the flowers, with the exception of a thrips ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design
