Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

Ecological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Towards a Notion of Distributed Time for Petri Nets

, 2001
We set the ground for research on a timed extension of Petri nets where time parameters are associated with tokens and arcs carry constraints that qualify the age of tokens required for enabling. The novelty is that, rather than a single global clock, we

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...

Experimental and genomic evidence clarifies the mycorrhizal helper role of a widespread bacterium in Bishop pine forests

New Phytologist, EarlyView.
Hypothetical model of Paraburkholderia–EcMF–Bishop pine interactions. Summary Whether a widespread bacterial strain of Paraburkholderia can enhance the physiological responses of ectomycorrhizal fungi (EcMF) and host Bishop pine seedling growth remains unclear. We developed a ‘top‐down meets bottom‐up’ approach that harmonized data from molecular field

High-Level Petri Nets as Type Theories in the Join Calculus

, 2001
We study the expressiveness of the join calculus by comparison with (generalised, coloured) Petri nets and using tools from type theory. More precisely, we consider four classes of nets of increasing expressiveness, $PN_i$, introduce a hierarchy of type ...

Properties of Distributed Time Arc Petri Nets

, 2001
In recent work we started a research on a distributed-timed extension of Petri nets where time parameters are associated with tokens and arcs carry constraints that qualify the age of tokens required for enabling.

Room to regenerate: microhabitats and the recruitment niche as drivers of mountain woodland restoration

Restoration Ecology, EarlyView.
Abstract Introduction Natural regeneration is an efficient, minimal‐intervention approach essential for facilitating resilient, self‐sustaining ecosystems during woodland restoration. However, recruitment can be slow, uncertain, or highly restricted, particularly in mountain woodland systems where tree planting and large herbivore management are ...

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

A Mechanism for Analyzing the Energy Consumption and Environmental Impact of LoRa Sensors Over Time

International Journal of Communication Systems, Volume 39, Issue 15, October 2026.
An SPN‐based mechanism, validated against NS‐3 with MAPE below 0.3%, reveals how packet generation rate and spreading factor shape LoRa sensor lifetime, energy consumption, and operational CO2$$ {}_2 $$ emissions, supporting sustainable planning of large‐scale IoT deployments. ABSTRACT Long Range (LoRa) sensors are widely adopted in Internet of Things (

Planning with Stochastic Petri-Nets and Neural Nets [PDF]

, 2006
This talk presents a synergistic methodology based on generalized stochastic Petri-nets (SPN) and neural nets for efficiently developing planning strategies. The SPN planning method generates global plans based on the states of the elements of the Universe of Discourse.
