Structure and dynamics of phytoplankton in an Amazon lake, Brazil

Revista de Biología Tropical, 2010
Natural lake systems represent important reservoirs for residential water supply, fish production, recreational activities and enjoyment of their natural beauty. Nevertheless, human impacts may affect their health status resulting in degradation and loss

Multiple Community Informants Enhance Public Information About Predators Across a Latitudinal Gradient in Bird Communities of China

Integrative Zoology, EarlyView.
We investigated bird communities across a 1650‐km latitudinal gradient in China where there is a transition in which “community informant” species play important roles in providing public information about predation, from babblers in the south to tits in the north. We found that both babblers and tits jointly contribute vocalizations when they are both

Over Two Decades of MODIS-Derived Chlorophyll-a Phenology and Long-Term Trends in Ancient Tropical Lake Poso, Indonesia

Limnological Review
Tropical lake ecosystems are vulnerable to degradation due to climate change and anthropogenic pressure. These dual pressures lead to ecological change and alterations in aquatic parameters, including chlorophyll-a (Chl-a). Lake Poso is the third-largest

Effects of El Niño on the dynamics of Lake Alchichica, central Mexico [PDF]

Geofísica Internacional, 2003
Lake Alchichica is a deep, warm-monomictic lake in Puebla State, central Mexico. Water temperature, dissolved oxygen and chlorophyll a annual concentration patterns are compared under ENSO and non-ENSO conditions.

Microarrayed Allergen Molecules Distinguish IgE Sensitisation to Blomia tropicalis and Dermatophagoides pteronyssinus

Allergy, EarlyView.
This study established a microarray containing a representative panel of purified Blo t and Der p allergens for the identification of patients sensitised to Blo t and/or Der p. Results indicate that the microarray based on Blo t and Der p allergens is a useful tool for the identification of Blo t‐ and/or Der p‐sensitised patients. The microarray may be

Energy Channel Coupling by Mid‐Trophic Level Fish Challenges the Landscape Theory for Food Web Architecture in a Large Tropical Lake Ecosystem

Ecology and Evolution
Landscape theory for food web architecture (LTFWA) posits that the stability of food webs is supported by the coupling of fast pelagic and slow littoral energy channels mediated by large mobile consumers.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
