Journal of Bioresource Management

Herbivore's attack stimulates chemical production in the plants; that communicates with natural enemies (chemical communication) and urges them for help (i.e. cry-for-help phenomenon). Such chemicals play an important role to attract the parasitoids and increase the chances of host pests' encounter. Current studies were performed to observe the extracts' efficacy in order to attract the parasitoid (i.e. Diadegma insulare) and thereby increase the likelihood of encounter with the host pest (i.e. Plutella xylostella). Cruciferous cultivars' extracts were developed and applied with artificial release of parasitoids under semi-field conditions. Findings revealed that extracts had the potential to enhance the …

Journal of Bioresource Management

The present study was conducted to compare the performance and behavior of Fayoumi and Rhode Island Red poultry breeds. A total of forty-two birds at 26 weeks of age, with thirty-six females and six males from each breed, were distributed into 6 groups with one male and six females each. All the experimental groups were reared in separate partitions with provisions of nests, feeders, and drinkers under proper management conditions. The results of the current study revealed that Rhode Island Red chickens showed significantly higher (P < 0.05) body weight, egg weight, daily egg production, eggshell thickness, and other quality parameters compared to Fayoumi chickens. It was also noted that Rhode Island Red chickens consumed less feed and gained heavier bodies with higher egg production than Fayoumi chickens. There was a non-significant difference in feed intake between both breeds. Rhode Island Red chickens produced eggs with better shell quality and higher breaking strength compared to Fayoumi chickens. In conclusion, the Rhode Island Red chicken breed is better in terms of body weight, egg performance, and feed efficiency compared to Fayoumi chickens.

Biological Sciences Faculty Publications

Emerging infectious diseases threaten wildlife globally. While the effects of infectious diseases on hosts with severe infections and high mortality rates often receive considerable attention, effects on hosts that persist despite infection are less frequently studied. To understand how persisting host populations change in the face of disease, we quantified changes to the capture rates of Eptesicus fuscus (big brown bats), a persisting species susceptible to infection by the invasive fungal pathogen Pseudogymnoascus destructans (Pd; causative agent for white-nose syndrome), across the eastern US using a 30-year dataset. Capture rates of male and female E. fuscus increased from preinvasion to …

Declines in biodiversity generated by anthropogenic stressors at both species and population levels can alter emergent processes instrumental to ecosystem function and resilience. As such, understanding the role of biodiversity in ecosystem function and its response to climate perturbation is increasingly important, especially in tropical systems where responses to changes in biodiversity are less predictable and more challenging to assess experimentally. Using large-scale transplant experiments conducted at five neotropical sites, we documented the impacts of changes in intraspecific and interspecific plant richness in the genus Piper on insect herbivory, insect richness, and ecosystem resilience to perturbations in water availability.
