Spatial and seasonal patterns of potential orchard pollinators across a Lake Ontario gradient

open access: yesAgricultural and Forest Entomology, EarlyView.
Potential pollinator captures varied by season, trap height and distance from Lake Ontario, indicating that flower visitors were not evenly distributed during apple bloom. Several common bee genera, including Lasioglossum, Agapostemon, Andrena and Apis, overlapped more closely with apple bloom than the dominant retained fly genus, Toxomerus.

EFFECT EXERTED ON SOIL PROPERTIES BY APPLE-TREE CULTIVATION FOR MANY YEARS AND BY REPLANTATION. PART II. CONTENT OF MINERAL COMPONENTS IN SOIL AND LEAVES

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2011
Studies were carried out in the years 2008–2009 in the Experimental Orchard of Fruit Growing Department, on the area of RSGD in Przybroda. Apple-trees of ‘Topaz’ cultivar on M.26 rootstock were planted in five soil localities: 1 – directly in grubbed up

Characteristics of water supply and demand in an agroforestry ecosystem under long-term continuous cropping assessed using the RZWQM2 model

open access: yesAgricultural Water Management
Sustainable agricultural management is one of the important factors for ensuring food security. In recent years, many wheat and maize fields on the Loess Plateau of China have been transformed into apple orchards for better economic returns. However, the

Multi‐Spectral Gaussian Splatting with Neural Color Representation

open access: yesComputer Graphics Forum, EarlyView.
Abstract 3D Gaussian Splatting (3DGS) [KKLD23] has transformed novel‐view synthesis from RGB images, yet remains restricted to the visible spectrum. Many applications, including agricultural monitoring, rely on multi‐spectral imaging, where spectral camera alignment and scalability pose major challenges.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

open access: yesChildren &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Control of sooty blotch and black rot of apple through removal of fruit mummies

open access: yesFolia Horticulturae, 2015
Several popular apple cultivars retain their aborted fruits as mummies on the tree. In laboratory conditions, overwintered fruit mummies collected from a Northern German apple orchard under organic management released inoculum, which caused black rot due

The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

YOLO11-ARAF: An Accurate and Lightweight Method for Apple Detection in Real-World Complex Orchard Environments

open access: yesAgriculture
Accurate object detection is a fundamental component of autonomous apple-picking systems. In response to the insufficient recognition performance and poor generalization capacity of existing detection algorithms under unstructured orchard scenarios, we ...

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...
