The capacity for birds to adjust their breeding time to variation in spring temperature via plasticity is crucial for insectivorous passerines in temperate areas, particularly in a context of climate disruptions. Recent studies suggested that phenological plasticity varies in response to environmental change via urbanization. We investigated the effects of urbanization on laying date, its phenotyp
Female-producing parthenogenesis is widespread in stick insects. It ranges from rare in sexual species to facultative or obligate, the latter sometimes in hybrids. This review synthesizes current knowledge on its origins, mechanisms, and evolutionary consequences, highlighting the distinction between hybrid and intra-specific origins. Hybrid-derived parthenogens are rare, obligate, frequently poly
Rising global temperatures and compound climatic extremes outpace avian thermoregulatory capacity. Yet, heat tolerance has been studied in only 1–2% of birds, mostly from the southern subtropics. The field requires research in two main areas. First, temperature and humidity must be considered in unison, and we provide a guiding, biophysical, framework for how these factors interact across climates
Objective: Testicular torsion (TT) is a medical emergency, difficult to identify solely through clinical evaluation. This study aims to develop an assessment algorithm with a safe lower threshold for complementary ultrasound. Material and methods: Males between 1 and 30 years of age assessed for suspected TT during the years 2019 – 2023 were retrospectively included. Clinical assessments were cond
Hundreds of active learning assignments are reported in the political education literature. However, the adaptability of these assignments to new courses can be limited by different learning outcomes, course themes, or institutional contexts. To assist educators in developing assignments that align with their teaching needs, this study introduces the concept of element design. Element design refer
We seek to clarify the impact of the Genetic Aptitude for Educational Attainment (GAEA) on risk for 10 psychiatric disorders divided into 4 groups: Internalizing, Externalizing, Eating/Compulsive and Psychotic. Educational attainment and psychiatric and substance use disorder information were obtained from national Swedish registries. GAEA and disorder-specific family genetic risk score (FGRS) wer
Water markets in China have received ample scholarly attention, but less is known about the political, ideological, and international influences that shaped their evolution. Using institutional analysis and a power-centered approach, we trace three Australian-funded projects (2005–2019) alongside domestic policy shifts to analyze how market ideas were institutionalized. We show how policy entrepre
Accounting for the estimated number of undescribed species, Gelechioidea are thought to be among the most species-rich superfamilies of Lepidoptera, with 18,500 described species, including numerous pests of economically significant crops such as cotton, tomato and wheat. Family-level topology of the superfamily and the extent and the number of accepted families have received important revisions t
Nestling feeding in altricial birds is a physiologically demanding phase of the annual cycle. Accordingly, parental effort in breeding songbirds has been suggested to be limited by the maximum capacity to perform sustained aerobic work. However, the maximum capacity for exercise and plasticity thereof is understudied in free-living, breeding songbirds. We tested two predictions related to the plas

This thesis explores the development of a digital twin for a real-life tunnel facility in Revinge, Skåne, using fire simulations and machine learning. The study aimed to identify preferred machine learning algorithms and compare fire simulation tools in terms of efficiency and performance. A literature review highlighted Long Short Term Memory (LSTM) networks as a suitable choice. Fire simulations
A new genus and species of emperor butterfly (Nymphalidae, Apaturinae) is described based on an exceptionally well-preserved specimen from the "Calcaire de Campagne Calavon" limestone of southern France (early Oligocene age, approximately 34–28 Mya). Most parts of the right wings and upper parts of the left wings are visible, with complete venation and even wing patterns. The head and thorax are c
Sundaland, a subcontinent situated in the Indo-Malay Archipelago, is characterized by a dynamic climatic, geological, and geographical history and a correspondingly diverse biota. The distribution of this biota follows complex biogeographical patterns, with high levels of local endemism and frequent instances of hidden diversity—greater genetic differentiation than expected based on phenotype. Bio
In recent years the development and use of crash prediction models for roadway safety analyses have received substantial attention. These models, also known as safety performance functions (SPFs), relate the expected crash frequency of roadway elements (intersections, road segments, on-ramps) to traffic volumes and other geometric and operational characteristics. A commonly practiced approach for
We investigated the elemental composition of spores and hyphae of arbuscular mycorrhizal fungi (AMF) collected from two saline sites at the desert border in Tunisia, and of Glomus intraradices grown in vitro with or without addition of NaCl to the medium, by proton-induced X-ray emission. We compared the elemental composition of the field AMF to those of the soil and the associated plants. The spo
The exchange of carbohydrates and mineral nutrients in the arbuscular mycorrhizal symbiosis must be controlled by both partners in order to sustain an evolutionarily stable mutualism. Plants down-regulate their carbon flow to the fungus when nutrient levels are sufficient, while the mechanism controlling fungal nutrient transfer is unknown. Here we show that the fungus accumulates nutrients when c
Biobank samples stored in biobanks give researchers and respiratory healthcare institutions access to datasets of analytes valuable for both diagnostic and research practices. The usefulness of these samples in clinical decision-making is highly dependent on their quality and integrity. New procedures that better preserve sample integrity and reduce degradation are being developed to meet the need
Tracking migratory movement of small animals with variable migration patterns is difficult with standard mark-recapture methods or genetic analysis. We used stable hydrogen isotope (delta D) measurements of wings from European red admirals Vanessa atalanta to study several aspects of this species' migration. In the central part of southern Europe we found large differences in delta D values betwee
