Summary A major challenge of current ecological research is to determine the responses plant and animal communities ecosystem processes future environmental conditions. Ecosystems respond climate change in complex ways, outcome may significantly depend on biodiversity. We studied relative effects enhanced drought species mixture soil biota litter decomposition a Mediterranean oak forest. experimentally reduced precipitation, accounting for seasonal precipitation variability, created...
In contrast to plant-animal interactions, the conceptual framework regarding impact of secondary metabolites in mediating plant-plant interference is currently less well defined. Here, we address hypotheses about role chemically-mediated (i.e., allelopathy) as a driver Mediterranean forest dynamics. Growth and defense abilities pioneer (Pinus halepensis) late-successional (Quercus pubescens) species were evaluated under three different plant conditions: (i) allelopathy simulated by...
Summary Over a century of agricultural abandonment across the Mediterranean region has favoured installation pioneer expansionist species Aleppo pine ( Pinus halepensis Miller). This synthesizes wide range secondary metabolites that are partially released during needle decomposition, and which can thus affect ‘brown food chain’. Litter decomposition is key process connecting ecosystem structure function, involving microbial faunal components. The goal this study was to determine effect...
Climate change is increasing crop losses and yield variability with impacts for global food security. In this context, conservation agriculture appears as a potential solution to maintain productivity, soil fertility environmental sustainability. Therefore, understanding the combined effects of tillage succession over long period primary interest. study, we analyzed data from 50 year long-term field experiment assess (i) climatic parameters, wheat organic carbon (SOC) content; (ii)...
Abstract The Mediterranean region is recognized as a global biodiversity hotspot. However, over the last decades, cessation of traditional farming in north part basin has given way to strong afforestation leading occurrence abandoned agricultural lands colonized by pioneer expansionist species like Pinus halepensis . This pine known synthesize wide range secondary metabolites, and previous studies have demonstrated allelopathic potentialities its needle root leachates. also release...
Abstract Anthropogenic climate change is altering precipitation regimes at a global scale. While changes have been linked to in the abundance and diversity of soil litter invertebrate fauna forests, general trends remained elusive due mixed results from primary studies. We used meta‐analysis based on 430 comparisons 38 studies address associated knowledge gaps, (i) quantifying impacts forest diversity, (ii) exploring reasons for variation (iii) examining biases affecting realism accuracy...
Closely related species often conserve similar niches despite interacting negatively. We suggest that close relatives may interact positively via ecosystem feedbacks: leaf litter produced or exposed in a closely neighbourhood (low phylogenetic isolation) decompose more quickly, leading to rapid nutrient recycling. studied decomposition of oaks Quercus petraea across 8 and 14 months, reciprocally transplanting litters between low high isolation distinguish effects mediated by quality...
Abstract. Soil biogenic volatile organic compound (BVOC) emissions have been studied in different biomes, showing that their are not negligible. However, previous studies so far neglected the role of litter accumulation on soil BVOC fluxes, and most them refer to coniferous evergreen forests, while from Mediterranean deciduous forests remain poorly explored. To fill these gaps, present work aimed study fluxes a forest, with particular attention relationship between biomass soils....
Abstract Plant litter decomposition is an essential ecosystem function that contributes to carbon and nutrient cycling in streams. Aquatic shredders, mainly macroinvertebrates, can affect this process various ways; they consume leaf litter, breaking it down into fragments creating suitable habitats or resources for other organisms through the production of fine particulate organic matter ( FPOM ). However, measures litter‐feeding traits across a wide range aquatic macroinvertebrates are...
Abstract The ongoing climate change may strongly impact soil biodiversity with cascading effects on the processes they drive. Thus, it is of prime interest to improve our knowledge about responses by organisms such as collembolans expected shifts in environmental conditions considering communities comprising both detritivores and predators. aim present study was evaluate how simulated predation under laboratory alter a collembolan community. To infer change, we applied decreased level...
Organisms release and detect molecules for defense, reproduction, feeding strategies finding suitable habitats. For some migratory species, homing behavior could be related to the recognition of their home chemical fingerprint made an assemblage from habitat. In marine realm, functioning ecosystems such as underwater caves largely depends on trophic interactions between outside environment. A key feature these relies circadian migration small crustaceans (Mysida) cave habitat open sea....
Abstract Increasing soil organic carbon (SOC) in agroecosystems is necessary to mitigate climate change and degradation. Management practices designed reach this goal call for a deeper understanding of the processes drivers input stabilization. We identified main SOC stabilization oil palm plantations using well‐defined spatial patterns nutrients litter application resulting from usual management scheme. The palm‐derived (OP‐SOC) was quantified by δ 13 C shift C4 (savanna) C3 (oil palm)...
Within a local assemblage, ecosystem engineers can have major impacts on population dynamics, community composition and functions by transforming or creating new habitats. They act as an ecological filter altering through set of environmental variables. The impact ants their environment has been widely studied, but multi-component effects (both trophic non-trophic) rarely addressed. We investigated the roles Messor barbarus , one commonest harvester ant species in south-western European...
