La reserva de semillas en una cuenca de "badlands" (Petrer, Alicante)
1992
In order to determine the influence of erosion in the absence of vegetation of badlands slopes, the seed content of the regolith and the seed removal by runoff in five storms were analyzed in an experimental catchment at Petrer (Alicante). Both, seed redistribution and seed loss were detected, but these seem to be insufficient to explain the lack of vegetation. It is hypothesized that besides the erosion process, factors such as pedoclimate, and chemical and physical properties of the regolith should be considered.
Sabanejewia Aurata (De Filippi, 1863) Populations Management Decisions Support System for Rosci0132 (Olt River Basin)
2015
Abstract The ADONIS: CE was used to design a specific management model for the Sabanejewia aurata (De Filippi, 1863) populations. The proposed model is based on this species, in situ identified biological/ecological necessities in relation to the habitats, the conservation status indicators and appropriate management actions and the pressures and threats founded in the study area. Such on species, on habitats and on site based management system was done to complete this approach for ROSCI0132, the other fish species which are living there being treated already in this respect.
Natural isotopes support groundwater origin as a driver of mire type and biodiversity in Slitere National Park, Latvia
2020
Slitere National Park in Latvia is home to rich fens with many endangered and threatened plant species. This study aims to address how the hydrological systems affect vegetation biodiversity (cf. Wolejko et al. 2019) in the mire systems of the National Park: the base-rich inter-dune mires and extremely base-rich calcareous fens. Groundwater samples from these areas were collected for measurements of ion composition and natural isotopes of C, H and O. Also, we simulated groundwater flow paths from the highest local topographical point (a nearby sandy plateau) to the sea, and calculated the residence times of these groundwater flows. The results show that the inter-dune mires are supplied by …
Herbivore-Induced Changes in Cotton Modulates Reproductive Behavior in the Moth Spodoptera littoralis
2017
Plants produce chemical defense compounds to resist herbivore attack either by repelling the herbivores or attracting natural enemies of the herbivores. We have previously shown that volatile compounds from cotton released in response to herbivory by conspecifics reduce oviposition in cotton leafworm moth Spodoptera littoralis. It remained, however, unclear whether herbivore-induced changes also affect moth pre-mating and mating behaviors. In this study we examined the effect of herbivore-induced changes in cotton on reproductive behaviors i.e., female calling, male attraction and investment, and mating behavior in S. littoralis. We found a reduction in the number of females calling i.e., f…

Droplet digital PCR as a tool for investigating dynamics of cryptic symbionts
2021
Abstract Interactions among symbiotic organisms and their hosts are major drivers of ecological and evolutionary processes. Monitoring the infection patterns among natural populations and identifying factors affecting these interactions are critical for understanding symbiont–host relationships. However, many of these interactions remain understudied since the knowledge about the symbiont species is lacking, which hinders the development of appropriate tools. In this study, we developed a digital droplet PCR (ddPCR) assay based on apicomplexan COX1 gene to detect an undescribed agamococcidian symbiont. We show that the method gives precise and reproducible results and enables detecting cryp…
The Universitary Educational System, Cibernetic System
2009
The national system of higher education shall solve one of the most difficult and most important social and human issues – the education and training of the young generation, of the labour hand. The system of higher education appears as a subsystem of the national educational system and of the society. That is why it appears the urgency of the artificial unrestriction of the university educational subsystem by the economy system. Economy’s vision of the university’s education subsystem must respond in these conditions to the following questions: What services and under what form should give the university at a time? Who should provide these services? What methods and strategies will be addr…
LEGAL CONSIDERATIONS REGARDING THE INTRODUCTION AND IMPLEMENT OF THE PROPOSED `FINANCIAL TRANSACTION TAX` ON PENSION FUNDS. IMPACT ON TRANSACTION COS…
2012
In economies in which pension obligations are substantial, it is important that there is a high degree of trust in the financial reporting of pensions by employers and by pension plans. The objective of this paper is to assess legal considerations regarding the introduction and implement of financial transaction tax mechanisms in private pension system. In line with this objective, an understanding of causes, implications, solutions for pensions is essential to being able to efficiently and effectively create a secure fiscal environment.
The toughest animals of the Earth versus global warming: Effects of long-term experimental warming on tardigrade community structure of a temperate d…
2021
Abstract Understanding how different taxa respond to global warming is essential for predicting future changes and elaborating strategies to buffer them. Tardigrades are well known for their ability to survive environmental stressors, such as drying and freezing, by undergoing cryptobiosis and rapidly recovering their metabolic function after stressors cease. Determining the extent to which animals that undergo cryptobiosis are affected by environmental warming will help to understand the real magnitude climate change will have on these organisms. Here, we report on the responses of tardigrades within a five‐year‐long, field‐based artificial warming experiment, which consisted of 12 open‐to…
Should dispersers be fast learners? Modeling the role of cognition in dispersal syndromes.
2021
Abstract Both cognitive abilities and dispersal tendencies can vary strongly between individuals. Since cognitive abilities may help dealing with unknown circumstances, it is conceivable that dispersers may rely more heavily on learning abilities than residents. However, cognitive abilities are costly and leaving a familiar place might result in losing the advantage of having learned to deal with local conditions. Thus, individuals which invested in learning to cope with local conditions may be better off staying at their natal place. In order to disentangle the complex relationship between dispersal and learning abilities, we implemented individual‐based simulations. By allowing for develo…
