A State and Transition framework to guide riparian woodland vegetation management and environmental water decisions
Published: 2024-09-30
Subjects: Terrestrial and Aquatic Ecology
River regulation and water extraction are major threats to the health and persistence of water-dependent ecosystems, such as riparian woodlands and forests. In heavily modified agricultural landscapes, riparian vegetation is also impacted by site-level stressors like livestock grazing, tree clearing, and weed invasions. Complex interactions among spatial and temporal drivers in water-dependent [...]
Current knowledge on the novel semiarid photovoltaic ecosystems and their impacts on biodiversity
Published: 2024-08-26
Subjects: Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology
The transition from fossil fuels to renewable energy sources is fundamental to mitigate the effects of global climate change. Renewable power capacity is increasing globally, and solar photovoltaic will be the dominant renewable energy source by 2050. Photovoltaic parks require great extensions of land, usually in drylands. But both ecosystems created by solar parks and the effect of solar parks [...]
Sunlight and diel behaviors promote coexistence of frogs through temporal acoustic partitioning
Published: 2024-08-12
Subjects: Behavior and Ethology, Longitudinal Data Analysis and Time Series, Statistical Methodology, Statistical Models, Terrestrial and Aquatic Ecology, Zoology
Understanding how species coexist is one of the main goals in ecology. While many have documented how species coexist in nature, there is much interspecific and spatial heterogeneity in which resources are partitioned and in the contributing environmental factors. Overall, we lack a general understanding of how stable coexistence is maintained for particular groups of organisms. Thus, we studied [...]
An integrated population modelling workflow for supporting mesopredator management
Published: 2024-08-01
Subjects: Applied Statistics, Biodiversity, Biostatistics, Ecology and Evolutionary Biology, Longitudinal Data Analysis and Time Series, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Survival Analysis, Terrestrial and Aquatic Ecology, Zoology
Expanding populations of mesopredators threaten biodiversity and human health in many ecosystems across the world. Lethal control through harvest is commonly implemented as a mitigation measure, yet the effects of harvest and its interaction with environmental conditions on mesopredator population dynamics have rarely been assessed quantitatively due to data constraints. Recent advances [...]
Seasonal Migrants and Traditional Ecological Knowledge in a Region of Risk: The Pulse Seine Fisheries in Limfjorden, Denmark, c. 1740-1860
Published: 2024-07-31
Subjects: Aquaculture and Fisheries Life Sciences, Arts and Humanities, Biodiversity, Economic History, Environmental Studies, Marine Biology, Other Arts and Humanities, Terrestrial and Aquatic Ecology
This article presents the commercial scale and organization of the Danish pulse seine eel fishery in the Limfjord before the advent of modern offshore fisheries. Partly, for environmental concerns, the pulse seine fishery was tightly regulated, with every seine having to be checked and certified by the local district bailiffs. Here, we present the first in-depth analysis of all preserved [...]
Emergent relationships between the functional diversity of marine zooplankton and ecosystem functioning in the global ocean
Published: 2024-07-23
Subjects: Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology
Copepods are a major group of the mesozooplankton and thus a key part of marine ecosystems worldwide. Their fitness and life strategies are determined by their functional traits which allow different species to exploit various ecological niches. The range of functional traits expressed in a community define its functional diversity (FD), which can be used to investigate how communities utilize [...]
Bimodal seasonal activity of moths and elevation, weather and land use as drivers of their diversity
Published: 2024-07-23
Subjects: Biodiversity, Entomology, Life Sciences, Terrestrial and Aquatic Ecology
Moths are an important part of terrestrial insect diversity and contribute substantially to ecosys-tem functioning. Yet, how their activity varies with the season and how different biotic and abiotic factors (elevation, weather, land use) are simultaneously linked to moth community characteristics are still poorly understood. We analysed a vast moth community dataset from Switzerland collected by [...]
Detection of energetic equivalence depends on food web architecture and estimators of energy use
Published: 2024-07-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Ecologists have long debated the universality of the energetic equivalence rule (EER), which posits that population energy use should be invariant with average body size due to negative size–density scaling. We explored size–density and size–energy use scaling across 183 geographically–distributed soil invertebrate food webs to investigate the universality of these fundamental EER assumptions. [...]
The economic risk of the losses in pest control as frogs decline
Published: 2024-07-04
Subjects: Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Crop pests threaten agricultural productivity, causing significant economic losses and food security issues. Although various control methods exist, pesticide reliance raises health and environmental concerns. In this sense, the Integrated Pest Management (IPM) is a favored approach that minimizes pesticide use while incorporating diverse pest control methods. A key aspect of IPM is biological [...]
Tundra vegetation community, not microclimate, controls asynchrony of above and belowground phenology
Published: 2024-06-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Plant Sciences, Plant Biology, Plant Sciences, Terrestrial and Aquatic Ecology
The below-ground growing season often extends beyond the above-ground growing season in tundra ecosystems. However, we do not yet know where and when this occurs and whether these phenological asynchronies are driven by variation in local vegetation communities or by spatial variation in microclimate. Here, we combined above- and below-ground plant phenology metrics to compare the relative [...]
trophiCH - a national species-level trophic metaweb of 23k species for Switzerland
Published: 2024-06-20
Subjects: Terrestrial and Aquatic Ecology
Environmental pressures on species can cascade within food webs and even extend beyond individual ecosystems to interconnected systems at large spatial scales. To facilitate the exploration of these dynamics, we construct a data-based national trophic meta-food web (henceforth metaweb), that includes well-documented vertebrates, invertebrates, and vascular plants within Switzerland's national [...]
Species- and community-level demographic responses of saplings to drought during tropical secondary succession
Published: 2024-06-01
Subjects: Climate, Environmental Indicators and Impact Assessment, Forest Biology, Plant Biology, Terrestrial and Aquatic Ecology
Naturally regenerating secondary vegetation dominates the tropical forest landscapes, showing a remarkable capacity to sequester carbon, but such a role is threatened by increasing drought predicted with climate change. To understand how secondary forest species and communities respond to drought, we leverage a long-term chronosequence of tropical successional forests from Central Panama that [...]
