An increasing body of evidence has shown that nighttime sap flux occurs in most plants, but the physiological implications and regulatory mechanism are poorly known. The significance of corticular photosynthesis has received much attention during the last decade, however, the knowledge of the relationship between corticular photosynthesis and nocturnal stem sap flow is limited at present. In th...

Parasites are one of the ecologically most relevant groups of marine food webs, but their taxonomic and biological complexity hampers the assessment of their diversity and evolutionary trends. Moreover, the within-host processes that govern parasitoid infection, development and reproduction are often unknown. In this study, we describe a new species of a perkinsozoan endoparasitoid that infects...

Little attention has been paid to the impact of vertical canopy position on leaf spectral properties tall trees, and few studies have explored ability spectra characterize variation traits across different positions. Using a tower crane, we collected samples from three layers (lower, middle, upper) measured eight (equivalent water thickness, specific area, carbon content, nitrogen phosphorus ch...

A study of zooplankton diversity and water quality Lake Dogodogo located in West Burundi was carried out from April to July 2021 six sampling stations, with four selected the littoral zone two remaining pelagic one. The main objective assess using indices for a better management this fishery resource essential surrounding populations. collected twice month between 8 A.M 11 each time. samples we...

We studied the zooplankton community composition at different depths (2, 4, 8, 12 and 20 m) of Valle de Bravo, a drinking water reservoirin central Mexico during December 2005 to November 2006. Temperature, dissolved oxygen, pH and chlorophyll a were measured simultaneously. While physicochemical values were similar to those found in previous studies, total zooplankton abundance was higher (mea...

1. A year-round study was conducted in a mesotrophic reservoir to determine the dynamics of zooplankton populations as a function of food availability (edible phytoplankton), nutrient concentration, temperature and hydraulic regime. 2. Rotifer biomass was correlated with soluble reactive phosphorus (SRP) concentration. The abundance of the rotifers Keratella cochlearis and Anuraeopsis fissa wer...

The effects of seasonal drought, belowground competition, and low soil fertility on the survival and growth over 2 years of four native tree species planted on a degraded hillside grassland in Hong Kong were studied in a field transplant experiment using three-way analysis of variance. The tree species were Schima superba (Theaceae), Castanopsis fissa (Fagaceae), Schefflera octophylla (Araliace...
