Foliar diagnosis in Phalaenopsis orchid plants subjected to application of nitrogen

open access: yesAfrican Journal of Agricultural Research, 2015
Production of orchids is important in floriculture, and nitrogen is one of the nutrients most required by plants. However, there is little information on nitrogen leaf analysis of these orchids. We evaluated the nitrogen fertilization on leaf nutritional status and on the production of dry mass and develop a diagnostic sheet for the orchid Phalaenopsis.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

open access: yesPest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Corn Yield and Foliar Diagnosis Affected by Nitrogen Fertilization and Inoculation with Azospirillum brasilense [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2016
ABSTRACT The biological nitrogen fixation (BNF) process in grasses is caused by diazotrophic bacteria, particularly Azospirillum brasilense. However, studies are lacking on BNF efficiency to define how much mineral nitrogen (N) can be applied to achieve more sustainable high yields.

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Multi‐Vine Disease Prediction in a Field Test Spanning Whole Growth Season at Wine‐Industrial Site (McLaren Vale)

open access: yesArtificial Intelligence for Engineering, EarlyView.
Overall, the findings provide reliable evidence for block‐level disease early warning, inspection prioritisation, and spray decision‐making, helping to reduce unnecessary inputs, lower environmental burdens, and improve the resilience and sustainability of vineyard production systems.

Relationship between tree nutritional status and apple quality

open access: yesHorticultural Science, 2014
Development of prediction models for the quality of apples is useful in guiding fruit tree nutrition and in optimising fruit management. The interrelationships between the leaf nutrient contents and some fruit quality indices were studied in five apple ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

open access: yesJournal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.
