Tracking and analysing economic and social changes in the agricultural sector is vital for decision makers, sectoral parties, professional and advocacy organisations and research institutions. Collected statistical data serve as a basis for domestic decision making and provide the foundation of strategy formulation in rural development, agro-environmental protection and sustainable agriculture. In the course of our research, analyses based on statistical databases were used to assess land use changes and land market prices. The structural survey of the Hungarian Central Statistical Office in 2013 shows that the proportion of business organisations utilising arable land grew 7 percentage points while individual farms increased their share by 2 percentage points. Our research shows that the concentration of land use increased demand for land and thus contributed to the increase in land prices.

The long-term objective is to understand how large masses of neurons in the brain process information during various learning and memory paradigms. Both time- and space-dependent processes have been identified in animals through computer-based analytic quantifications of event-related extracellular potentials. New nonlinear analyses have been introduced that presume that the fine-grain variation in the signal is determined and patterned in phase-space. Some neurons in the primary visual cortex manifest gamma-band oscillations. These cells show both a nonspecific phase-alignment (response synchrony) and a specific tuning (orientation tuning) when stimuli are presented to their receptive fields. This dual regulation of the sensory cells is proposed to underlie stimulus binding, a theoretical mechanism for "object" perception. Nonlinear analytic results from gamma-activities in a simple model neuropil (olfactory bulb) suggest that neuroplasticity may arise through self-organization, a process in which a nonlinear change in the dynamics of the oscillatory field potentials is the hallmark. This self-organization may follow simple dynamical laws in which global cooperativity among the neurons is transiently brought about that, over trials, results in enduring changes in the nonlinear dynamics of some neurons. In conclusion, the sculpturing of the synaptic throughput in the sensory cortex (stimulus binding) may be associated with the irregular phases of the gamma-activities and may result from both specific and nonspecific systems operating together in a nonlinear self-organizing manner.

The rate of telomere loss is increasingly being used as a marker of biological aging, organismal senescence, and survival probability. These protective ends of chromosomes act to protect coding DNA during replication and by buffering against degradation from reactive oxygen species (ROS). In many organisms, telomere loss has been linked to increased levels of metabolism, biological stress and disease. Here we validate a medium-throughput and reliable method to measure relative telomere length in Sand Martins Riparia riparia. We performed the qPCR assay on a population of variously aged individuals from eastern Hungary. We detected a significant negative relationship between relative telomere length and age and observed a clear drop in telomere length in older age classes (> 4 years) but no relationship with gender or body mass. Our results in this cross-sectional study support findings in other passerine species that report a lack of long telomeres in older individuals. The method that we describe will allow longitudinal studies of Sand Martin individuals in wild populations to track telomere dynamics related to various life history characteristics and individual health.
