Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size–abundance slope of −0.75 that is invariant across environments. We tested the robustness of this relationship across gradients of protist species richness (1–6 species), temperature (15°C–25°C) and time. Using replicated microcosms, we pro
Context. Globular clusters exhibit star-to-star chemical variations that are traceable through both photometric and spectroscopic data. While UV photometry and light-elements such as Na and O are commonly used for this purpose, the optical V versus (V-I) color magnitude diagram (CMD) is often assumed to be relatively unaffected by such inhomogeneities and is used to derive basic cluster parameters
The aim of this workshopreport is to move beyond existing academicdiscussions on environmental politics in North and EastSyria3, and to respond directly to the region’s urgentenvironmental needs and challenges, and to explorepossible pathways for ecological recovery and justice.We seek to critically examine the political, social, andecological dimensions of environmental governancein post-conflict
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionall
Anthropogenic land-use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous. The buff-tailed bumblebee (Bombus terrestris) is a widespread species th
OBJECTIVE: Glomerular filtration rate (GFR) is generally accepted as the best overall index of renal function. Thus, all potential live kidney donors are tested to ensure that they have a normal GFR before they are eligible for kidney transplantation. The choice of GFR test is very much dependent on local traditions and may include iohexol, 51Cr-EDTA, inulin, or creatinine clearance based on urine
Aim: The degree to which species' niches remain stable over space and time–the niche conservatism hypothesis–is critical for predicting species' responses to environmental change. Tests of this hypothesis typically focus on changes in niche centroids and boundaries. An outstanding question is whether species' environmental associations differ within the interior of their niche space–that is, acros
This thesis concerns localisation, shape reconstruction and pose estimation from monocular images. While multiple cameras allows for triangulation to capture depth in scenes, monocular settings require some of relative features, reasonable real-world assumptions, regularisation, Machine Learning (ML) or a combination of these. The accompanying articles to this compilation thesis treats several top
Although the ~200 impact craters known on Earth represent only a small fraction of the craters originally formed, the available data suggest an excess of craters by one order of magnitude, in number, in the interval ca. 470-440 Ma during the Ordovician. Most of these “excess” craters may be related to the breakup of the L-chondrite parent body (LCPB) in the asteroid belt at 465.8 ± 0.3 Ma. This is
Residential gardens can provide pollinator habitat and thus contribute to mitigating declines of insect pollinators. To further improve gardens for pollinators, it is necessary to understand the factors and pathways leading to successful conservation interventions. We studied how the success of two common pro-pollinator interventions, garden meadows and flower plantings, were influenced by gardene
Hepatitis B virus (HBV), hepatitis delta virus (HDV), and hepatitis C virus (HCV) remain leading drivers of chronic viral hepatitis, cirrhosis, hepatocellular carcinoma, and liver-related mortality. This ESCMID Study Group for Viral Hepatitis (ESGVH) narrative review summarizes recent advances and expert perspectives in the field. For HBV, emerging biomarkers such as quantitative HBs antigen, HBV
Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.
Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates at low transverse momentum are much lower than the rate from standard model multijet production. This Letter describes a new search for dijet resonances where this limitation is
Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. Subjective probability is an example of a quantitative expression of e
The ongoing wide-scale introduction of nonnative plants across the world may negatively influence native invertebrate fauna, due to a lack of coevolved traits related to the novel plants, e.g., unique phytochemicals or shifted phenology. Nonnative plants, specifically trees, are common in urban environments, areas that already pose novel habitats to plants and wildlife through a wide array of anth
Green infrastructure (GI) is increasingly used in policymaking to promote biodiversity and enhance ecosystem services through the protection, creation, restoration and connection of natural and man-made green areas. The EU Commission adopted in 2013, the concept as a strategy. When member states apply the policy, it is translated into specific bureaucratic and political systems, creating different
