Resource partitioning among African savanna herbivores in North Cameroon: the importance of diet composition, food quality and body mass [PDF]

, 2011
The relationship between herbivore diet quality, and diet composition (the range of food plants consumed) and body mass on resource partitioning of herbivores remains the subject of an ongoing scientific debate.

More Robust Co-Occurrence Patterns and Stronger Dispersal Limitations of Bacterial Communities in Wet than Dry Seasons of Riparian Wetlands

mSystems, 2023
Riparian wetlands can be used as “sentinels” of environmental changes and play pivotal roles in ecological and biogeochemical processes. The bacterial community is an essential and rapidly responding component in riparian areas.

Environmental changes during secondary succession in a tropical dry forest in Mexico [PDF]

, 2011
Vegetation and environment change mutually during secondary succession, yet the idiosyncrasies of the vegetation effect on the understorey environment are poorly understood. To test whether the successional understorey environment changes predictably and

Monitoring Gaseous and Particulate Air Pollutants near Major Highways in Abeokuta, Nigeria

Journal of Applied Sciences and Environmental Management, 2016
High traffic volume and traffic congestion on Nigerian roads have led to increase in the concentration of pollutants in the air t posing health risks for human population. This study investigates air quality due to vehicular emissions in some busy roads

One year of spectroscopic high‐frequency measurements of atmospheric CO2, CH4, H2O and δ13C‐CO2 at an Australian Savanna site

Geoscience Data Journal, 2023
We provide a 1‐year dataset of atmospheric surface CO2, CH4 and H2O concentrations and δ13C‐CO2 values from an Australian savanna site. These semi‐arid ecosystems act as carbon sinks in wet years but the persistence of the sink in dry years is uncertain.

Trends in the start of the wet season over Africa [PDF]

, 2008
A quarter of a century of daily rainfall data from the Global Telecommunications System are used to define the temporal and spatial variability of the start of the wet season over Africa and surrounding extreme south of Europe and parts of the Middle ...

Regimes of the North Australian Wet Season [PDF]

Journal of Climate, 2009
Abstract The variability of the north Australian wet season is examined by performing cluster analysis on the wind and thermodynamic information contained in the 2300 UTC radiosonde data at Darwin for 49 wet seasons (September–April) from 1957/58 to 2005/06. Five objectively derived regimes of the wet season are obtained and are found to

Seasonal cycle of precipitation variability in South America on intraseasonal timescales [PDF]

, 2017
The seasonal cycle of the intraseasonal (IS) variability of precipitation in South America is described through the analysis of bandpass filtered outgoing longwave radiation (OLR) anomalies.
