Study the effect of the host on the survival and energy budget of Habrobracon hebetor (Hym., Braconidae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران
Using of biological control agents, especially parasitoids, within the Integrated Pest Management (IPM) programs is increasingly expanding. Several factors can influence the effectiveness of parasitoids, the most important of which is the type and ...

Camera‐trap data do not indicate scaling of diel activity and cathemerality with body mass in an East African mammal assemblage

open access: yesEcology and Evolution, 2021
Diel activity patterns of animal species reflect constraints imposed by morphological, physiological, and behavioral trade‐offs, but these trade‐offs are rarely quantified for multispecies assemblages. Based on a systematic year‐long camera‐trap study in

Energy budget increases reduce mean streamflow more than snow–rain transitions: using integrated modeling to isolate climate change impacts on Rocky Mountain hydrology

open access: yesEnvironmental Research Letters, 2016
In snow-dominated mountain regions, a warming climate is expected to alter two drivers of hydrology: (1) decrease the fraction of precipitation falling as snow; and (2) increase surface energy available to drive evapotranspiration.

Influence of Propulsion Type on the Stratified Near Wake of an Axisymmetric Self-Propelled Body

open access: yesJournal of Marine Science and Engineering, 2018
To better understand the influence of swirl on the thermally-stratified near wake of a self-propelled axisymmetric vehicle, three propulsor schemes were considered: a single propeller, contra-rotating propellers (CRP), and a zero-swirl, uniform-velocity ...

Assessing the impact of forest structure disturbances on the arboreal movement and energetics of orangutans—An agent-based modeling approach

open access: yesFrontiers in Ecology and Evolution, 2022
Agent-based models have been developed and widely employed to assess the impact of disturbances or conservation management on animal habitat use, population development, and viability.

Impacts of Irrigation on the Heat Fluxes and Near-Surface Temperature in an Inland Irrigation Area of Northern China

open access: yesEnergies, 2014
Irrigated agriculture has the potential to alter regional to global climate significantly. We investigate how irrigation will affect regional climate in the future in an inland irrigation area of northern China, focusing on its effects on heat fluxes and

Appraising the brain's energy budget [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
In the average adult human, the brain represents about 2% of the body weight. Remarkably, despite its relatively small size, the brain accounts for about 20% of the oxygen and, hence, calories consumed by the body (1). This high rate of metabolism is remarkably constant despite widely varying mental and motoric activity (2).

Effects of different stocking densities on the CO2 fluxes at water-air interface and the respiration metabolism in sea cucumber Apostichopus japonicus (Selenka)

open access: yesFrontiers in Marine Science, 2022
Recently, abundant research has been devoted to investigating the variations of CO2 concentration in the atmosphere. However, the information of CO2 fluxes at the water-air interface remains limited, especially those from the respiratory metabolism of ...

Characteristics of summer-time energy exchange in a high Arctic tundra heath 2000–2010 [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2014
Global warming will bring about changes in surface energy balance of Arctic ecosystems, which will have implications for ecosystem structure and functioning, as well as for climate system feedback mechanisms. In this study, we present a unique, long-term

Effects of tillage method on the carbon footprint, energy budget, and net ecosystem economic efficiency of rice fields

open access: yesFrontiers in Sustainable Food Systems, 2023
Biaxial rotary tillage is considered an effective approach for enhancing the structure of soil in rice fields. There are few reports on the effects of biaxial rotary tillage on the carbon footprint (CF), energy budget, and net ecosystem economic ...
