Villari, Caterina. « Fungi associated with the pine engraver beetle Ips acuminatus and their interactions with the host tree ». Doctoral thesis, Università degli studi di Padova, 2012. http://hdl.handle.net/11577/3422532.
Texte intégralGli scolitidi delle conifere sono insetti spesso associati ad un complesso di funghi con i quali possono instaurare differenti interazioni ecologiche. Alcuni di questi funghi, generalmente non fitopatogeni, sono coinvolti in un’interazione mutualistica diretta e vengono utilizzati come nutrimento per le larve del vettore. Altri funghi associati, invece, sono ritenuti coinvolti nel processo di esaurimento delle difese della pianta, che per l’insetto è uno dei passaggi necessari per superare la resistenza dell’ospite e poterlo quindi colonizzare. In quest’ultimo caso, i funghi associati sono di norma specie patogene appartenenti al gruppo morfologico dei funghi ophiostomatoidi, noti anche come ‘funghi di azzurramento’. Nonostante l’interesse che la simbiosi tra scolitidi e funghi ha riscosso nel tempo, molti degli aspetti fondamentali di questa interazione sono ancora discussi, come ad esempio il grado di dipendenza degli insetti vettori dai loro simbionti nelle fasi di colonizzazione della pianta ospite. In questa tesi è stata presa in considerazione la comunità fungina associata a Ips acuminatus (Gyll.), un piccolo scolitide che attacca di preferenza le parti del tronco del pino silvestre (Pinus sylvestris L.) con corteccia sottile, e che di recente ha causato numerose infestazioni in varie zone distribuite sull’arco alpino. Una delle specie che fanno parte della comunità fungina associata ad I. acuminatus è il simbionte alimentare Hyalorhinocladiella macrospora (Franke-Grosm.) Harr. Fa inoltre parte del complesso anche uno specifico fungo di azzurramento costantemente associato al vettore, ma la cui identità non è ancora ben definita. Le prime segnalazioni lo descrivono come Ophiostoma clavatum Math.-Käärik, mentre ricerche successive riportano O. brunneo-ciliatum Math. Gli obiettivi che questa tesi si è prefissa sono stati determinare l’effettiva identità del fungo di azzurramento associato ad I. acuminatus, ed indagare le interazioni del complesso fungino con la pianta ospite, al fine di definire meglio le relazioni che intercorrono tra scolitidi e fungi associati, e poter quindi contribuire ai tentativi di chiarire l’ecologia e la dinamica di popolazione di questo insetto dannoso. Nel primo lavoro sono stati descritti l’isolamento e l’identificazione di una specie fungina isolata da individui di I. acuminatus raccolti in Italia e in Svezia. L’identificazione della specie è avvenuta sia grazie all’osservazione delle caratteristiche morfologiche sia mediante un approccio di tipo molecolare. La specie è risultata essere O. clavatum, come era stato indicato nelle prime segnalazioni riguardanti i funghi associati ad I. acuminatus. Nel secondo lavoro sono stati descritti la messa punto e l’utilizzo di tre sonde molecolari per loop-mediated isothermal amplification (LAMP), con l’obiettivo di determinare quale delle due specie del genere Ophiostoma sopracitate fosse effettivamente il fungo maggiormente associato a I. acuminatus nell’arco alpino. I risultati, riguardanti sei popolazioni italiane dell’insetto, hanno confermato che la specie maggiormente presente è O. clavatum, mentre O. brunneo-ciliatum non è mai stata rilevata. I risultati di questo studio hanno mostrato anche che la frequenza di associazione di I. acuminatus con O. clavatum varia a seconda della fase epidemica, ed è minore nei nuclei di infestazione rispetto alle popolazioni endemiche. Nel terzo lavoro sono state caratterizzate le risposte sia locali sia sistemiche del pino silvestre alla colonizzazione da parte del simbionte alimentare e del fungo di azzurramento, identificando e quantificando alcuni metaboliti secondari, come terpeni, fenoli e lignina. I risultati hanno mostrato che il pino silvestre risponde in maniera generica anziché specifica all’induzione. Il fatto inoltre che il simbionte alimentare e il fungo di azzurramento abbiano stimolato una risposta simile di loro suggerisce che anche un fungo non patogeno possa partecipare al processo di esaurimento delle difese della pianta, assistendo quindi l’insetto nelle fasi di colonizzazione dell’ospite. Questo risultato contribuisce quindi allo sviluppo delle attuali teorie sul ruolo dei funghi associati nell’ecologia degli scolitidi. Nell’ultimo lavoro sono state studiate le correlazioni tra i metaboliti secondari delle difese costitutive del pino silvestre, e le correlazioni tra la concentrazione costitutiva e la variazione indotta dei singoli composti. I risultati hanno messo in evidenza una differenziazione di comportamento tra composti e l’assenza in generale di una correlazione inversa tra i tipi diversi di difese, al contrario di quanto previsto da alcune teorie. Nel complesso, i quattro contributi di questa tesi suggeriscono la rivalutazione di una delle attuali teorie sul ruolo dei funghi associati nella colonizzazione dell’ospite da parte degli scolitidi, e forniscono degli spunti per la comprensione del ruolo dei funghi associati nella dinamica di popolazione del vettore. Chiariscono inoltre alcuni degli aspetti dei meccanismi di difesa del pino silvestre, mettendo in evidenza la sua competitività.

Texte intégralThe Holocene spread of Picea abies in Scandinavia provides an excellent opportunity for detailed study of the dynamics of tree spread and population expansion. Early- and mid-Holocene macrofossil evidence for the presence of Picea abies in Scandinavia has questioned traditional interpretations of the timing and direction of its spread. This study aims to determine the pattern of the spread of Picea abies in Scandinavia from pollen and other data, to evaluate the significance of possible early outpost populations and to deduce possible factors that influenced the spread and population expansion of Picea abies in Scandinavia.
Palaeoecological investigations were carried out on the sediments of four small lakes in central Sweden to gain detailed insight into the dynamics of the spread. Holocene pollen diagrams with independent dating control were collected from Fennoscandia and adjacent areas to compare the timing of selected features of the Picea abies pollen curve. Computer models were used to test possible scenarios for the spread and Picea abies population expansion.
Picea abies entered the Scandinavian peninsula from the east at different times and by different pathways. Early-Holocene outposts can be discerned in pollen records from northwest Russia, eastern and northeastern Finland for the time before 9000 cal. BP. Pollen records from Sweden and Norway indicate small Picea abies populations after 8000 cal. BP. The mid to late-Holocene spread, which superficially resembles a front-like pattern, may in fact represent a wave of expanding populations. Disturbance through fire and human activity did not significantly influence the pattern of the spread. Changing climate parameters, slow adaptation and gene flow through seeds and pollen have to be considered as possible explanations for the late spread of the tree. Population dynamics and propagule pressure are likely to be important factors that shaped the spread of Picea abies.

Texte intégralThe dynamics of the tree component of a Mixed Ombrophylous Forest in the Southeast Brazil was evaluated to verify its successional stage and its agreement with dynamic models proposed for this formation. The first one, Lozenge model, or temporal plot replacement, proposes that the dynamics of long-lived pioneers, often gymnosperms, which structurally dominates the forest, is influenced by intermittent recruitment pattern, dependent of severe disturbances. The second proposes that the presence of Araucaria angustifolia is indicative of ongoing succession and that the A. angustifolia fate is to be substituted by broadleaf species. A third one proposes gap dependent recruitment for the long-lived pioneers. The evaluation was conducted in three phases: through the analysis of the dynamics of the phytosociological structure it was observed if changes occurred in the order of importance of the species, with a demographic analysis to characterize the size structure of the tree populations and through the analysis of the spatial dynamics of the forest it was investigated if gap formation fostered the recruitment of long-lived pioneers. The results showed a phytosociological structure with no change in the order of importance of the species, although it was observed an increase in the representation of umbrophyllous species in the understory and the reduction of sun tolerant species. The demographic analysis showed that the gymnosperms present a cohort structure in accordance with what is expected for long-lived pioneers and that during the observed time span they did not recruit, indicating a decline in their population. The canopy species presented populations in development and, in the uderstorey, a more intense dynamic was observed with population increases for the umbrophyllous species. The spatial analysis showed that many species are independent of gaps for recruitment and development but the forest recruitment, mortality and species enrichment are correlated with this process. It was not observed the recruitment of long-lived pioneers in the gaps presented in the study area. These results indicate that the forest is under development and that its dynamics is influenced by the dynamics of the long-lived pioneers. There was indication of adherence to the first two models and that, in the absence of major disturbances, it can be expected that the long-lived pioneers will be replaced.
