Human impacts on Earth's ecosystems have greatly intensified in the last decades. This is reflected unexpected disturbance events, as well new and increasing socio-economic demands, all of which are affecting resilience forest worldwide provision important ecosystem services. Anthropocene era forcing us to reconsider past current management silvicultural practices, search for ones that more flexible better at dealing with uncertainty brought about by these accelerating cumulative global...
Many parasites modify their host behaviour to improve own transmission and survival, but the proximate mechanisms remain poorly understood. An original model consists of parasitoid Dinocampus coccinellae its coccinellid host, Coleomegilla maculata ; during manipulation, is not in contact with anymore. We report herein discovery characterization a new RNA virus ( D. paralysis virus, DcPV). Using combination RT-qPCR electron microscopy, we demonstrate that DcPV stored oviduct females,...
Host manipulation by parasites not only captures the imagination but has important epidemiological implications. The conventional view is that face a trade-off between benefits of host and their costs to fitness-related traits, such as longevity fecundity. However, this hypothesis remains be tested. Dinocampus coccinellae common parasitic wasp spotted lady beetle Coleomegilla maculata. Females deposit single egg in haemocoel host, during larval development parasitoid feeds on tissues. At...
Designing effective habitat and protected area networks, which sustain species-rich communities is a critical conservation challenge. Recent decades have witnessed the emergence of new computational methods for analyzing prioritizing connectivity needs multiple species. We argue that goal multispecies should be focused on long-term persistence set species in landscape or seascape. Here we present review literature based 77 papers published between 2010 2020, assess current state recent...
Parasitic organisms rely on the resources of their hosts to obtain nutrients essential for growth and reproduction. Insect parasitoids constitute an extreme condition since they develop in a single host from which typically consume all available resources. As result, is killed following parasitism. However, few intriguing cases survival have been reported wherein resume foraging may even reproduce parasitoid emergence. Yet, ultimate proximate mechanisms responsible recovery remain...
Although host manipulation is likely to be costly for parasites, we still have a poor understanding of the energetic aspects underlying this strategy. It traditionally assumed that physiological costs are inevitably associated with mechanisms evolved by parasites induce required changes in behaviours. While most expenditures relate primarily bringing about altered behaviours, manipulative also consider condition their during manipulation. Here, suggest because trade-off, energy accomplish...
Abstract By definition, insect parasitoids kill their host during development. Data are presented showing that ladybirds not only can survive parasitism by D inocampus coccinellae , but also retain capacity to reproduce following parasitoid emergence. We hypothesize behaviour manipulation constitutes a preadaptation leading the attenuation of virulence. Following larval development, egresses from and spins cocoon between ladybird's legs. Throughout pupation, manipulated acts as bodyguard...

Recent decades have witnessed the emergence of new computational methods for analyzing prioritizing connectivity needs multiple species. We argue that goal multispecies prioritizations be long-term persistence set species in landscape suggest index metapopulation capacity as one metric by to assess compare effectiveness proposed network designs.

Abstract The importance of urban tree diversity for improving resilience is increasingly understood by decision makers. Urban foresters want to prevent the overrepresentation species on their streets and in city, which could result a significant loss canopy cover event large-scale disturbance such as drought or an exotic pest disease. Although numerous software tools exist visualize inventories plan maintenance work, only few offer support increasing diversity. After reviewing existing...
A new approach to immunizing our forests against uncertainty (essay) In the present context of global change, managing is a major challenge, in particular because great associated with this change. Faced reality, methods monitoring and forecasting developments are no longer effective enough, so we have review how manage forests. Complexity theory provides conceptual framework for approach, which leads us adopt more holistic flexible way seeing world when planning forest management. We must...
