- Abstract:
- ... Changes in environmental conditions may influence the biosynthesis of several food nutrients. This study aimed to compare macronutrient and mineral composition over several seasons in 25 fresh plant-based foods that are highly consumed and locally produced in the southern Ecuadorian highlands. Samples were collected during the rainy season (October 2015–March 2016) and dry season (April–September ...

- Abstract:

It forms the headwaters of the Nile River and serves as the primary dry season water source for an estimated 1.1 million rural people and the largest remaining overland migration of 1.4 million wildebeest in the Serengeti-Mara Ecosystem. Changes throughout the basin are impacting the quantity and quality of the Mara River, ...

- Abstract:
- ... Hydrological extremes have negative impacts on natural, agricultural, and urban landscapes and place substantial ecological pressure on freshwater habitats. However, the role of artificial freshwater habitats during hydrological drought is poorly understood. Insects make up much of total aquatic fauna and lend themselves to understanding how drought impacts freshwater ecosystems. Using the Greater ...

Evolutionary computation has been applied to predict the occurrence of massive cyanobacteria proliferations; in the present study, this tool was further used to explore the factors responsible for maintaining picocyanobacterial dominance. Aiming to increase the understanding of factors that promote dominance of picocyanobacteria in tropical reservoirs, we chose two reservoirs used for water suppli ...

- Abstract:
- ... Grain amaranth, Amaranthus L., is an emerging crop cultivated worldwide. One way in which resources from the amaranth crop could be exploited as an alternative to grain is to grow amaranth in the dry season, harvest only the leaves, and incorporate them into meals. In this environmental condition, insects associated with the amaranth crop are poorly known. Results showed that Diabrotica balteata L ...

- Abstract:
- ... Rivers and streams are important agents for global and regional carbon cycle, which represent a nonnegligible carbon source to the atmosphere. However, carbon dioxide (CO2) degassing via water-air interface from inland waters currently has a large uncertainty in estimation. Here we examined the CO2 partial pressure (pCO2) and CO2 degassing in the Daning River, a main tributary of the Yangtze in th ...

Such understanding is crucial in tropical areas where landslide impacts are high and on the rise, and the dearth of accurate processes characterisation is large.

Parasites with low host specificity (e.g. infecting a large diversity of host species) are of special interest in disease ecology, as they are likely more capable of circumventing ecological or evolutionary barriers to infect new hosts than are specialist parasites. Yet for many parasites, host specificity is not fixed and can vary in response to environmental conditions. Using data on host associ ...

Mangroves are forest ecosystems located at the interface between land and sea where sediments presented a variety of contrasted environmental conditions (i.e. oxic/anoxic, non‐sulfidic/sulfidic, organic matter content) providing an ideal ecosystem to study microbial communities with niche differentiation and distinct community structures. In this work, prokaryotic and fungal compositions were inve ...

- Abstract:
- ... Understanding how habitat heterogeneity is linked to biodiversity patterns within flood–pulse catchments is needed for their effective conservation. To study those communities, researchers have begun to explore how local environmental factors influence species composition patterns at relatively fine scales within complex habitat mosaics. However, a robust description of the link between communitie ...

Understanding spatial variation in fish trophic structures along large river systems remains a challenge, and the influence of fish food selectivity and diet shifts on these structures remains unknown. In this study, the assemblage composition and stomach contents of fish in the subtropical East River of southern China were analyzed to determine their diet composition (DC) and identify prey-orient ...

Although SWS is believed to hold the largest population of wild Eld's deer, there has been no investigative research carried out on the field ecology of this species in this specific region. In this study, we e ...

Information on their distribution, behaviour, habitat use, and estimated population density play an important role in the identification of critical areas and regulating human activities within. Here we examine the seasonal variatio ...

Spatiotemporal dynamics and drives of partial pressure of CO₂ (pCO₂) and water-air CO₂ fluxes (FCO₂) in a monsoonal headwater stream Jinshui River of the Yangtze were unraveled.

- Abstract:
- ... Phenology is a key component of the life-history of plants, and non-native plant species with distinctive phenological traits may have an advantage over native species. In tropical savannas, water and light availability are often spatially and temporally heterogeneous, so that non-native species capable of changing their phenology in response to these factors are more likely to succeed in these ec ...

The host-parasite dynamics in tropical bat assemblages are less known, and migh ...
