The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

ChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is

Polarization-Based Digital Histology of Human Skin Biopsies Assisted by Deep Learning

Photonics
Mueller polarimetry has proven to be a powerful optical technique to complement medical doctors in their conventional histology analysis. In this work, various degenerative and malignant human skin lesions were evaluated ex vivo using imaging Mueller ...

Broad support for lethal control of wild deer among subscribers of nature organisations in England and Wales

People and Nature, EarlyView.
Abstract Wild deer populations are increasing across the northern hemisphere, posing challenges to the environment and people. Deer impacts can be managed using lethal and non‐lethal practices, but research suggests lethal control receives mixed support.

Competition Policy and Achieving Sustainable Development Goal 1 (No Poverty): The Role of Mergers and Acquisitions Adjudications in South Africa

Sustainable Development, EarlyView.
ABSTRACT South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited.

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE

Acta Crystallographica Section D, EarlyView.
This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Bayesian data reduction approaches in polarization imaging

EPJ Web of Conferences, 2010
The Stokes-Mueller formalism provides a coherent framework that permits obtaining polarization parameters from raw radiance acquisitions through a linear observation model. In polarization imaging, this observation model is extended to the whole image

The inter-temporal stability of real estate returns: an empirical investigation [PDF]

, 1998
This paper examines one of the central issues in the formulation of a sector/regional real estate portfolio strategy, i.e. whether the means, standard deviations and correlations between the returns are sufficiently stable over time to justify using ex ...

Characterization of Mueller matrices in retroreflexellipsometry

, 2021
Ellipsometry is a widely-used technique for characterizing materials and thinfilms. The principle is based on the polarization changes after light is reflectedor transmitted at a sample. In general, the shape of the sample should be flat ornearly flat because ellipsometry is sensitive to the angle of incidence, tilt angleand the sample position (height
