Environmental modulation of self‐organized periodic vegetation patterns in Sudan [PDF]

open access: yesEcography, 2011
Spatially periodic vegetation patterns in arid to semi‐arid regions have inspired numerous mechanistic models in the last decade. All embody a common principle of self‐organization and make concordant, hence robust, predictions on how environmental factors may modulate the morphological properties of these patterns.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Trends in vegetation productivity and seasonality for Namaqualand, South Africa between 1986 and 2011: an approach combining remote sensing and repeat photography [PDF]

open access: yes, 2013
This thesis presents an assessment of vegetation change and its drivers across a subset of Namaqualand, South Africa. Namaqualand forms part of the Succulent Karoo biome, which is characterised by exceptionally high species biodiversity but which has ...

Effects of submerged vegetation on water clarity across climates [PDF]

open access: yes, 2009
A positive feedback between submerged vegetation and water clarity forms the backbone of the alternative state theory in shallow lakes. The water clearing effect of aquatic vegetation may be caused by different physical, chemical, and biological ...

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Studies in the holocene vegetation history of Wensleydale [PDF]

open access: yes, 1985
Total and arboreal pollen diagrams have been prepared for three blanket bog sites and one valley bog in the Wensleydale area of the Yorkshire Dales. Local pollen assemblage zones have been defined for each site using numerical methods, and these have ...

Climate variability and human impact in South America during the last 2000 years: synthesis and perspectives from pollen records [PDF]

open access: yes, 2016
An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia. Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes

open access: yesAdvanced Science, EarlyView.
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Evaluation of the Length of the Vegetation Period of the Potato

open access: yesPlant Breeding and Seed Science, 2017
Abstract Potato cultivars are classified into maturity groups according to the length of the vegetation period required to produce a harvestable product. Although accurate classification of potato cultivars to a specific maturity group is of great practical importance, there is no standard method to characterize the maturity type of potato ...
