Determination of the abundance and diversity Lepidoptera in Andean Community San Benito, Cajamarca, Peru. Several samplings were carried out, using 500 linear m transect technique, with a monthly frequency throughout 2021, riparian areas surrounding vegetation. The material was dissected studied entomology laboratory National University Trujillo. analyzes species out. 206 individuals registered...

The concept and methods of ecological diversity in communities were applied to phytoplankton categorized by flow cytometric measurements related to size and chlorophyll content. Each cytometric signature was condensed to single numerical values indicative of diversity and evenness. Measurements pooled from studies disparate in temporal and spatial scales indicated greater chlorophyll biomass an...

Abstract One of nature’s most valuable resources, biodiversity plays a critical role in meeting many human requirements and protecting from environmental extremism conditions. Mollusca benthic invertebrates are important biota aquatic ecosystems need further investigation. The current study highlights some species recorded Al-Delmage Marsh Iraq. points out six Mollusca. These Melanoides tubercu...

Biological long-term data series in marine habitats are often used to identify anthropogenic impacts on the environment or climate induced regime shifts. However, particularly in transitional waters, environmental properties like water mass dynamics, salinity variability and the occurrence of oxygen minima not necessarily caused by either human activities or climate change can attenuate or mask...

recognizing the herbaceous plant species diversity could use as an importantindicator applied for the rangeland and forests management. considering the presence ofvegetation and animal husbandry in zagros region, iran, being aware of the diversity andrichness of plant species is necessary to management or the destructed vegetationrestoration. in order to study the effect of aspect and elevation...

Does influenza A affect body condition of wild mallard ducks, or vice versa? 1. INTRODUCTION Low pathogenic avian influenza (LPAI) viruses are well documented to circulate within wild waterfowl populations (Olsen et al. 2006). It has been assumed that these infections are benign with no subsequent effects on life-history parameters. The study by Latorre-Margalef et al. (2009; hereafter L.-M. et...

Xinjiang, a region of high salinity and drought, is a host to many arid and semi-arid plants. Many of these plants including Ferula spp. have indigenous pharmaceutical histories. As many of the medicinal properties of plants are in tandem with the associated microorganisms residing within the plant tissues, it is advisable to explore the endophytic potential of such plants. In the present study...

Macro-scale species richness studies often use museum specimens as their main source of information. However, such datasets are often strongly biased due to variation in sampling effort in space and time. These biases may strongly affect diversity estimates and may, thereby, obstruct solid inference on the underlying diversity drivers, as well as mislead conservation prioritization. In recent y...

Biomonitoring is a cheap and effective tool for evaluation of water quality, and infer on the balance of aquatic ecosystems. The benthic macroinvertebrates are bioindicators sensitive to environmental changes, and can assist in detecting and preventing impacts such as organic enrichment and imbalance in the food chain. We compared the structure of benthic communities on artificial substrate sam...

The feeding diversity of macroinvertebrates from the estuary of Mondego was estimated with Shannon–Wiener complementary evenness following the methodology presented in Gamito and Furtado (2009. Ecological Indicators, 9: 1009-1019). Results were compared with those from BAT (Benthic Assessment Tool; Teixeira et al., 2009. Marine Pollution Bulletin, 58: 1477-1786) applied to the same data set, ob...
