Starbursts in isolated galaxies. I. The influence of stellar birth function and IMF

, 2009
Starbursts and substantial variations in the star formation histories are a common phenomenon in galaxies. We study the stability properties of isolated star-forming dwarf galaxies with the aim of identifying starburst modes.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.

Aspects of forest biomass in the earth system: Its role and major unknowns

, 2019
Forests are a major and diverse land cover occupying a third of the terrestrial vegetated surface; they store 50 to 65% of terrestrial organic carbon (including the soil) and contribute half to terrestrial productivity. Forest biomass stores close to 80%

Adverse effects of grapevine trunk diseases on canes produced from infected rootstock mother blocks

Pest Management Science, EarlyView.
High incidences of GTD pathogens in rootstock mother vine heads, with Phaeomoniella chlamydospora and Diplodia seriata affecting cane physiology and quality. One‐year‐old canes harbor systemic inoculum, highlighting the need for careful monitoring and management.

Using the root spread information of pioneer plants to quantify their mitigation potential against shallow landslides and erosion in temperate humid climates [PDF]

, 2016
The aim of this paper was to quantify the mitigation potential of pioneer herbs against shallow landslidesand erosion in temperate humid climates and to identify key plant information to aid species selectionfor slope stabilisation. The objectives ranged

Field resistance of orange fruit to citrus black spot and citrus canker in D‐limonene synthase downregulated trees

Pest Management Science, EarlyView.
Genetically modified (GM) sweet‐oranges with downregulated CitMTSE1 gene showed reduced citrus black spot severity and citrus canker incidence, confirming terpene modulation as a promising strategy for sustainable field citrus disease resistance. Abstract BACKGROUND Citrus black spot (CBS), caused by Phyllosticta citricarpa, and citrus canker (CC ...
