Abiotic constraints on the activity of tropical lizards
Many tropical ectotherms are considered vulnerable to anthropogenic climate change because they have evolved to become thermal specialists. Indeed, several recent studies have suggested that even small increases in mean operative temperature may lead to a reduction in activity and the subsequent extinction of populations. Within the tropics, lizards are considered particularly vulnerable due to...


ESLab application to a boreal watershed in southern Finland: preparing for a virtual research environment of ecosystem services
We report on preparatory work to develop a virtual laboratory for ecosystem services, ESLab, and demonstrate its pilot application in southern Finland. The themes included in the pilot are related to biodiversity conservation, climate mitigation and eutrophication mitigation. ESLab is a research environment for ecosystem services (ES), which considers ES indicators at different landscape scales...
Effects of temperature on consumer-resource interactions
1. Understanding how temperature variation influences the negative (e.g.,self-limitation) and positive (e.g., saturating functional responses) feedback processes that characterize consumer-resource interactions is an important research priority. Previous work on this topic has yielded conflicting out comes with some studies predicting that warming should increase consumer-resource oscillations ...


Top-down and bottom-up forces interact at thermal range extremes on American lobster
1. Exploited marine populations are thought to be regulated by the effects of fishing, species interactions, and climate. Yet it is unclear how these forces interact and vary across a species’ range.2. We conducted a meta-analysis of American lobster (Homarus americanus) abundance data throughout the entirety of the species’ range, testing competing hypotheses about bottom-up (climate, temp...
Understanding the contribution of wild edible plants to rural social-ecological resilience in semi-arid Kenya
Wild edible plants (WEPs) are known to make important contributions to food baskets and livelihoods in the smallholder and subsistence farming communities of sub-Saharan Africa. As a result, protecting and promoting the sustainable use of WEPs in concert with more mainstream agricultural innovation efforts has the potential to build household resilience to food insecurity. There is, however, a ...


What does stakeholder involvement mean for fisheries management?
The Common Fisheries Policy (CFP) sets the guidelines for the management of European fisheries. The CFP is revised every 10 years, and the last two revisions have laid the groundwork for extending stakeholder participation in European Union fisheries management. The fishery industry and nongovernmental organization (NGOs) especially are recommended to be given greater influence. In this paper w...
Biogeochemical nitrogen properties of forest soils in the Japanese archipelago
This data paper provides some biogeochemical nitrogen (N) properties and related chemical properties of forest soils from 39 sites throughout the Japanese archipelago. The data set was collected and analyzed under the GRENE (Green Network of Excellence) environmental information project and the ReSIN (Regional and comparative Soil Incubation study on Nitrogen dynamics in forest ecosystems) proj...

Effects of hydrography on the distribution of bacteria and virus in Cochin estuary, India
The viral dynamics have rarely been investigated in estuarine environments of India. The present study brings out a first hand information on the distribution of virus and bacteria in an eutrophic estuary (Cochin, India). Thirteen stations were selected for monthly monitoring of bacterial abundance (BA), total viable bacterial count (TVC), viral abundance (VA), chlorophyll a (Chl a) and other w...
Life history consequences of larval foraging depth differ between two competing Anopheles mosquitoes
Anopheline larvae are surface feeders and allocate most of their time to search for food at the water surface. However, species of the Anopheles gambiae Giles complex may also show bottom feeding. The consequences of this foraging tactic for life history are unknown, yet may be relevant to understand inter-specific competition patterns.2. The diving ability and activity of larvae of the main Af...

Understanding the links between ecosystem service trade-offs and conflicts in protected areas
Land use changes induced by nature conservation regulation and management practices, especially in protected areas, often result in trade-offs between ecosystem services (ESs). Exploring trade-offs between ESs and linking them with stakeholders can help reveal the potential losers and winners of land use changes. In this paper, we demonstrate that ES trade-offs do not always go hand in hand wit...
A tiered approach for mapping ecosystem services
Ecosystem services (ES) mapping make the benefits of nature spatially explicit. The different methods used for ES mapping limit the comparability of outcomes and call for a more consistent but flexible approach. We present a four step tiered approach for ES mapping supporting scholars to select the adequate combination of variables: First, the user, researcher or policy maker defines the goal o...

Smooth brome changes gross soil nitrogen cycling processes during invasion of a rough fescue grassland
Invasive plants have variable effects on net nitrogen cycling, but how invasion alters gross N cycling is poorly understood. We examine how Bromus inermis (smooth brome) invasion affects gross N cycling rates and investigate potential mechanisms for the changes including relationships between smooth brome and ammonia-oxidizing bacteria (AOB) and archaea (AOA), plant community productivity, and ...
The high vulnerability of Quercus robur to drought at its southern margin paves the way for Quercus ilex
Populations growing at the warm margins of the species’ range are more prone to experience higher water stress compared to populations inhabiting the core of their distribution. Thus, assessing tree vulnerability to drought is crucial to improve prediction of forest mortality and species range limits. We quantified the abundance of two oak species (Quercus robur and Quercus ilex) along a wate...
Water chemistry of headwater streams under stormflow conditions in catchments covered by evergreen broadleaved forest and by coniferous plantation
It is important to determine the effects of vegetation on the water chemistry of headwater streams to ensure appropriate water resource management and landscape planning, particularly because vegetation is known to be one of the primary determinants of the chemistry in such streams and is easily altered by silvicultural operations. Previous studies of headwater stream water chemistry have inves...
Missing SO2 oxidant in the coastal atmosphere? – observations from high-resolution measurements of OH and atmospheric sulfur compounds
Diurnal and seasonal variations of gaseous sulfuric acid (H2SO4)and methane sulfonic acid (MSA) were measured in NE Atlantic air at theMace Head atmospheric research station during the years 2010 and 201Themeasurements utilized selected-ion chemical ionization mass spectrometry(SI/CIMS) with a detection limit for both compounds of 4.3 × 104 cm−3at 5 min signal integration. The H2SO4 and MSAg...
