Insect-Mediated Pollination of Strawberries in an Urban Environment
Insects, 2023 Pollination services provided by a diversity of pollinators are critical in agriculture because they enhance the yield of many crops. However, few studies have assessed pollination services in urban agricultural systems.

A vision-based robotic system for precision pollination of apples [PDF]
Computers and Electronics in Agriculture, Volume 234, 2025Global food production depends upon successful pollination, a process that relies on natural and managed pollinators. However, natural pollinators are declining due to factors such as climate change, habitat loss, and pesticide use. This paper presents an integrated robotic system for precision pollination in apples.

Global Convergence Analysis of the Flower Pollination Algorithm: A Discrete-Time Markov Chain Approach [PDF]
Procedia Computer Science, vol. 108, 1354-1364 (2017), 2018 Flower pollination algorithm is a recent metaheuristic algorithm for solving nonlinear global optimization problems. The algorithm has also been extended to solve multiobjective optimization with promising results. In this work, we analyze this algorithm mathematically and prove its convergence properties by using Markov chain theory.

Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Earth Surface Processes and Landforms, Volume 48, Issue 1, Page 215-229, January 2023., 2023 This paper uses a numerical landscape evolution model to reconstruct the topographic history of Madagascar since the Late Cretaceous. The model is optimised by balancing the volumes of onshore erosion and offshore sedimentation; the former is predicted with erosion laws and based on uplift history inferred from elevated planation surfaces.

An Approach of Adjusting the Switch Probability based on Dimension Size: A Case Study for Performance Improvement of the Flower Pollination Algorithm [PDF]
arXiv, 2022 Numerous meta-heuristic algorithms have been influenced by nature. Over the past couple of decades, their quantity has been significantly escalating. The majority of these algorithms attempt to emulate natural biological and physical phenomena. This research concentrates on the Flower Pollination algorithm, which is one of several bio-inspired ...

Pervasiveness of Parasites in Pollinators [PDF]
PLoS ONE, 2012 Many pollinator populations are declining, with large economic and ecological implications. Parasites are known to be an important factor in the some of the population declines of honey bees and bumblebees, but little is known about the parasites afflicting most other pollinators, or the extent of interspecific transmission or vectoring of parasites ...

Aquatic‐Terrestrial Insecticide Fluxes: Midges as Neonicotinoid Vectors
Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 60-70, January 2023., 2023 Abstract Exposure of freshwater ecosystems to insecticides can negatively impact the development of emerging aquatic insects. These insects serve as an important nutritional subsidy for terrestrial insectivores. Changes in insect emergence phenology (i.e., emergence success and temporal pattern) or fluxes of insecticides retained by the emerging adults

Integrating pollinators’ movements into pollination models
Frontiers in Ecology and EvolutionAccurate prediction of pollination processes is a key challenge for sustainable food production and the conservation of natural ecosystems. For many plants, pollen dispersal is mediated by the foraging movements of nectarivore animals. While most current models of pollination ecology assume random pollen movements, studies in animal behaviour show how ...
