Summary: Our study revealed a relationship between genetic variation levels within ponds of great crested newts and the surrounding landscape composition at various spatial scales. Different landscape features had varying effects on genetic variation, particularly within radii of 50 and 100 meters around core ponds.

Summary: The feeding behavior in the Danube crested newt undergoes significant changes throughout different ontogenetic stages, involving adjustments in food search, approach, and uptake mechanisms. These changes reflect an evolutionarily defined relation between locomotor and feeding systems control, with a switch from successive to integrated control during ontogeny, triggered by the formation of functional limbs in late larval development.

Summary: This study assessed the conservation status of the protected amphibian species, the Macedonian crested newt, in Northern Pindos National Park, Greece, using genetic approaches. The analysis of mitochondrial DNA sequences and multilocus genotypes revealed two distinct genetic groups of the species, separated geographically by the Aoos River valley and Vikos Gorge. These groups exhibit high genetic differentiation and low migration rates, indicating a lack of connectivity between breeding sites. The findings suggest that these groups should be considered as evolutionary significant units (ESUs) and managed separately for conservation purposes.

Summary: Amphibians, particularly European newts, are experiencing rapid declines in population abundance due to land-use change and invasive species. This study combines long-term distribution data with demographic models to assess the decline in newt abundance at a regional scale. The results show that local wetland characteristics, such as area and permanence, as well as the presence of fish and invasive crayfish, are the main factors influencing newt abundance dynamics.

Summary: Two large-bodied newt species, Triturus ivanbureschi and T. macedonicus, hybridize in nature across the Balkan Peninsula. This study examines the reproductive success and genetic composition of the first generation of hybrids. The results suggest that incompatibilities between mitochondrial and nuclear genomes may occur in later stages of development or subsequent hybrid generations.

Summary: Thiourea disrupts thyroid hormone synthesis and affects oxidative stress parameters in crested newt larvae, leading to larval characteristics retention and oxidative damage at high concentrations.

Summary: This study described the changes in skin structure during development in the Balkan crested newt. The skin in the larval stages consisted only of the epidermis, which developed into a stratified epidermis with glands and Leydig cells during late larval stage. Leydig cells disappeared during metamorphosis, and the dermal layer developed. In postmetamorphic stages, the skin differentiated into a stratified epidermis and well-developed dermis with various glands. The composition of the glands appeared to be stage- and sex-specific, with similarities between juveniles and adult females.

Summary: This work explores how the diurnal and annual cycles of Earth affect land surface temperature variations and proposes a method for quantifying the dynamics of annual and diurnal temperature simultaneously. The method is validated using data from continental Europe, demonstrating the impact of climate and surface conditions on the temperature profiles and showing an excellent agreement between satellite-derived and in-situ data.

Summary: This study examines the influence of pond physical characteristics on the genetic variability of pygmy newt populations and finds that landscape connectivity may be more important than hydroperiod length in determining genetic diversity and viability.

Summary: Maintaining habitat connectivity is crucial for genetic diversity and reducing the risk of inbreeding depression, particularly for amphibians. This study investigated the genetic structure and variation of two newt species in an urbanized and agricultural landscape and found that human-modified habitats negatively affected gene flow. Considering multiple spatial scales proved effective in improving landscape resistance models.

Summary: The study found that adding IVIG to RTX therapy did not increase the complete remission off rates, reduce time to complete remission off, time to steroid cessation, or decrease relapse rates. Factors associated with complete remission off included older age, younger age at the time of diagnosis, shorter disease duration before RTX treatment, lower BMI, and female gender.

Summary: The study of the two phylogeographic lineages of the four-eyed sleeper in the South China Sea and East China Sea revealed differences in reproductive seasonality, body size, and fecundity, which may affect mate choice and reproductive strategy. This suggests that lineage differences play a role in the incomplete reproductive isolation between the two lineages.

Summary: This article analyzes 11 years of near-surface meteorology using observations from an open-ocean surface mooring in the Northwestern Tropical Atlantic. It compares in situ data with three reanalyses and finds discrepancies in longwave and shortwave radiation fluxes, with some reanalyses showing significant bias.
