Autumn mass change and winter mass loss differ between migratory and nonmigratory butterflies

Poikilotherms have two major alternative strategies to deal with the inhospitable conditions of temperate winters: hibernation or migration. The vast majority of insects spend winter in a species-specific diapause resting stage, while others remain reproductively active after having migrated to more hospitable environments in the autumn. The butterfly clade Nymphalini offers an interesting possibi

Mapping Ecosystem Services, Disservices, and Ecological Requirements to Enhance Urban Forest Planning and Management in Padova

In Padova, the municipal department of green infrastructure monitors the urban forest through a continuously updated database that stores information about locations, species, dimensions, health conditions, and management of more than 47,000 trees. The aim of the research presented in this chapter was to support urban forest planning and management by integrating the existing database with informa

Evolvability and trait function predict phenotypic divergence of plant populations

Understanding the causes and limits of population divergence in phenotypic traits is a fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation to environmental change. Reciprocal transplant experiments and the evaluation of optimality models suggest that local adaptation is common but not universal, and some studies suggest that trait divergence is highly con

Proximity to oilseed rape fields affects plant pollination and pollinator-mediated selection on a co-flowering plant on the Tibetan Plateau

The ecological effects of mass-flowering crops on pollinator abundance and species richness of neighbouring habitats are well established, yet the potential evolutionary consequences remain unclear. We studied effects of proximity to a mass-flowering crop on the pollination of local co-flowering plants and on patterns of natural selection on a pollination-generalised plant on the Tibetan Plateau.

Linking microenvironment modification to species interactions and demography in an alpine plant community

Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we 1) determined the extent of species-specific microclimate modification by comparing temperature and soil moisture between vegetated

The rapid expansion of industrial agriculture in rural Bogotá has led to a reduction in the diversity of plants cultivated by peasant families. This generates transformations in livelihoods and biocultural relations, affecting local environmental knowledge and practices for the use and management of agrobiodiversity. Although several studies have documented the presence of agrobiodiversity niches,

Improved representation of phosphorus exchange on soil mineral surfaces reduces estimates of phosphorus limitation in temperate forest ecosystems

Phosphorus (P) availability affects the response of terrestrial ecosystems to environmental and climate change (e.g., elevated CO2), yet the magnitude of this effect remains uncertain. This uncertainty arises mainly from a lack of quantitative understanding of the soil biological and geochemical P cycling processes, particularly the P exchange with soil mineral surfaces, which is often described b

Microplastics affect activity and spatial distribution of C, N, and P hydrolases in rice rhizosphere

Microplastics provide a new ecological niche for microorganisms, and the accumulation levels of microplastics (MPs) in terrestrial ecosystems are higher than those in marine ecosystems. Here, we applied the zymography to investigate how MPs — polyethylene [PE], and polyvinyl chloride [PVC]) at two levels (0.01% and 1% soil weight) impacted the spatial distribution of soil hydrolases, nutrient avai

Citizen science initiatives increase pollinator activity in private gardens and green spaces

Wild insect pollinators are essential to cultivated and natural ecosystems globally. Today, many pollinator species are declining. One reason is a general lack of flowering habitats at landscape scales. However, urban areas, including private gardens, may provide flowers, and constitute beneficial habitats for pollinators. Here, we evaluate the ecological outcomes of a citizen science campaign run

Gardens’ contribution to people and urban green space

Cities are experiencing numerous challenges, adversely affecting human health and wellbeing. Urban green space provides ecosystem services that are important to meet urban challenges. One type of urban green space is private gardens (yards) that make up an essential part of many urban areas. Gardens can support urban biodiversity and provide cultural ecosystem services (CES) to its owner. However,

Digest : A synergistic approach explains the evolutionary connection between brain size and longevity*

The cognitive buffer hypothesis poses that brain size evolves to buffer individuals from environmental changes, increasing survival. Jiménez-Ortega et al. (2020) explored this hypothesis using a phylogenetic path analysis and showed that there is a direct causal link between brain size and longevity in birds, even when allometric effects are taken into account. Furthermore, a synergistic model was

Sustainable welfare in Swedish cities : Challenges of eco-social integration in urban sustainability governance

In this paper, we study the integration of ecological sustainability and social welfare concerns in cities. Efforts to handle ecological challenges risk having negative impacts on equality and social welfare. While current levels of consumption and material welfare are unsustainable, there is a need for more sustainable approaches to welfare and wellbeing. Still, ecological and social concerns in

Using ecological context to interpret spatiotemporal variation in natural selection

Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator-mediated selection on floral traits provides a good system for understanding and linking variation in selection to differences in ecological context. We studied pollinator-mediated selection in five populations of Dalechampia scandens (Euphorbiaceae) in Costa Rica and Mexico. Using a nonlinear path-ana

Pathways towards a sustainable future envisioned by early-career conservation researchers

Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation continues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization of, actions furthering sustainability. We conducted a survey (n = 67) and an interactive work

Value of cultural worldviews and message framing for the acceptability of sustainable land use zoning policies in post-conflict Somalia

Public acceptability is important for sustainable land use zoning policy to be successfully implemented. This study examined the effectiveness of tailoring messages with cultural worldviews to induce positive attitudes and improve public acceptability of sustainable land use zoning policy in a post-conflict setting. A total of 538 participants were randomly divided into three groups. Two were trea

A FUNCTIONAL VIEW REVEALS SUBSTANTIAL PREDICTABILITY OF POLLINATOR-MEDIATED SELECTION

A predictive understanding of adaptation to changing environments hinges on a mechanistic understanding of the extent and causes of variation in natural selection. Estimating variation in selection is difficult due to the complex relationships between phenotypic traits and fitness, and the uncertainty associated with individual selection estimates. Plant-pollinator interactions provide ideal syste

Scaling up nature-based solutions for climate-change adaptation : Potential and benefits in three European cities

Many exemplary projects have demonstrated that Nature-based Solutions (NBS) can contribute to climate change adaptation, but now the challenge is to scale up their use. Setting realistic policy goals requires knowing the amount of different NBS types that can fit in the urban space and the benefits that can be expected. This research aims to assess the potential for a full-scale implementation of
