Spatial Bayesian Modeling Applied to the Surveys of Xylella fastidiosa in Alicante (Spain) and Apulia (Italy)
2020
The plant-pathogenic bacterium Xylella fastidiosa was first reported in Europe in 2013, in the province of Lecce, Italy, where extensive areas were affected by the olive quick decline syndrome, caused by the subsp. pauca. In Alicante, Spain, almond leaf scorch, caused by X. fastidiosa subsp. multiplex, was detected in 2017. The effects of climatic and spatial factors on the geographic distribution of X. fastidiosa in these two infested regions in Europe were studied. The presence/absence data of X. fastidiosa in the official surveys were analyzed using Bayesian hierarchical models through the integrated nested Laplace approximation (INLA) methodology. Climatic covariates were obtained from …
CO2 EFFECTS ON SPAWNING RATES OF A MEDITERRANEAN NESTING WRASSE
2014
Some aspects of the reproductive behaviour of the ocellated wrasse Symphodus ocellatus (Forsskål 1775) were investigated in wild conditions along a pCO2 gradient. Our results show no differences in the number of females, sneakers and satellite males involved in the spawning phase under two pCO2 conditions. However, the spawning rate of nesting males was negatively affected in high pCO2, whilst exerted a normal reproductive pattern in ambient pCO2.
Preliminary observation on use of nest boxes in protected areas of Southern Sicily
2011
In this short note we summarize the data self-made nesting in nest boxes in two areas of NATURA 2000 in southern Sicily. The models of nest boxes considered host species during the study the following period: Falco naumanni, Falco tinnunculus, Athene noctua, Strix aluco, Sturnus unicolor, Parus major, Certhia brachydactyla, Corvus monedula, Passer montanus.
Cowbird versus cuckoo hosts: a comparative study of learned nest defense
2005
One of the best example of coevolutionaru adaptations is that of the interactions between avian brood parasites and their hosts. Brood parasites lay their eggs in nests of other specieis and leave the job of caring for their young with the hosts. Hosts of brood parasites tend to suffer high reproductive costs as often they raise few of no young of their own, an effect of being parasitizes. For this reason, many hosts have evolved strategies that reduces the cost of parasitism.

Species–area relationships in continuous vegetation: Evidence from Palaearctic grasslands
2019
Aim Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how sampling methodology or the environment influence SAR shape. Location Palaearctic grasslands and other non-forested habitats. Taxa Vascular plants, bryophytes and lichens. Methods We used the GrassPlot database, containing standardized vegetation-plot data from vascular plants, bryophytes and lichens spanning a wide range of grassland types throu…
Uz entropijas mēru balstīts daudzkritēriju lēmumu pieņemšanas modelis
2019
Bakalaura darbs ir veltīts svārstīgās nestriktās lingvistiskās entropijas un šķērsentropijas mēru pielietojumam daudzkritēriju lēmumu pieņemšanā. Darbā aprakstīts, kā, izmantojot kritēriju svaru vektora noteikšanas un alternatīvu kārtošanas metodes, tiek iegūts optimālais daudzkritēriju lēmumu pieņemšanas problēmas risinājums. Metožu teorētisko aprakstu papildina dažādu praktisku piemēru analīze.
Genomiskā nestabilitāte in vitro krūts vēža šūnu līnijās MDA-MD-436, MDA-MB-231 un SkBr3 hroniskas hipoksijas gadījumā
2017
Hipoksijas apstākļi audzēja mikrovidē var stimulēt genoma nestabilitāti, tādējādi veicinot agresīvāku slimības gaitu. Darba mērķis bija noteikt vieglas hroniskas hipoksijas ietekmi uz genoma nestabilitāti trīs dažādās krūts vēža šūnu līnijās. Šūnas tika kultivētas trīs pārsējumos hipoksijā (2 % O_2) un normoksijā (19, 95 % O_2). Vieglas hroniskas hipoksijas apstākļos tika novērota augstāka ar DNS reparācijas mehānismiem saistīto signālceļu gēnu ekspresija, palēnināta šūnu proliferācija, izmaiņas morfoloģijā, kā arī izmaiņas šūnas ciklā. Lielākās izmaiņas novērotas mazāk diferencētā šūnu līnijā (MDA-MB-436). Darbs izstrādāts RSU Onkoloģijas institūta Molekulārās ģenētikas laboratorijā no 201…
Potencjał słowotwórczy wybranych czasowników dźwiękonaśladowczych w języku czeskim i polskim
2017
The article is acontrastive analysis of word-forming potential for six Czech and Polish onomatopoeic verbs, such as: HLTAT / ŁYKNĄĆ; 2) CHLEMTAT / CHŁEPTAĆ; 3) CHROUPAT / CHRUPAĆ; 4) MLASKAT / MLASKAĆ; 5) SRKAT / CHLIPAĆ; 6) ŠPLOUCHAT / CHLUPAĆ. Using methodology of word-formation nests, two aspects of these words were analyzed: 1) abstract word-forming paradigm, 2) aword-forming chain. The analysis showed that in both languages onomatopoeic verbs quite regularly will derive verbs naming the result of the action and the verbs expressing intensity or weakening of the action. In Czech language there are also verbs naming completion of the action, verbs accentuating the beginning of the acti…
