| transpiration of urban forests in the los angeles metropolitan area. | despite its importance for urban planning, landscape management, and water management, there are very few in situ estimates of urban-forest transpiration. because urban forests contain an unusual and diverse mix of species from many regions worldwide, we hypothesized that species composition would be a more important driver of spatial variability in urban-forest transpiration than meteorological variables in the los angeles (california, usa) region. we used constant-heat sap-flow sensors to moni ... | 2011 | 21639035 |
| two trebouxia algae with different physiological performances are ever-present in lichen thalli of ramalina farinacea. coexistence versus competition? | ramalina farinacea is an epiphytic fruticose lichen that is relatively abundant in areas with mediterranean, subtropical or temperate climates. little is known about photobiont diversity in different lichen populations. the present study examines the phycobiont composition of several geographically distant populations of r. farinacea from the iberian peninsula, canary islands and california as well as the physiological performance of isolated phycobionts. based on anatomical observations and mol ... | 2010 | 21134099 |
| suitability of pines and other conifers as hosts for the invasive mediterranean pine engraver (coleoptera: scolytidae) in north america. | the invasive mediterranean pine engraver, orthotomicus erosus (wollaston) (coleoptera: scolytidae), was detected in north america in 2004, and it is currently distributed in the southern central valley of california. it originates from the mediterranean region, the middle east, and asia, and it reproduces on pines (pinus spp.). to identify potentially vulnerable native and adventive hosts in north america, no-choice host range tests were conducted in the laboratory on 22 conifer species. the bee ... | 2008 | 18613584 |
