Decreased frugivory and seed germination rate do not reduce seedling recruitment rates of Aristotelia chilensis in a fragmented forest
(2007)
Habitat fragmentation reduces frugivorous bird abundance. Such a reduction may lead to a reduction in seed dispersal, thereby compromising seedling recruitment rate with far reaching consequences for plant population ...
Effects of vagotomy on cardiovascular and heart rate variability alterations following chronic normobaric hypoxia in adult rabbits
(2018)
Abstract
Background
chronic hypoxia increases basal ventilation and pulmonary vascular resistance, with variable changes in arterial blood pressure and heart rate, but it’s ...
Faster male displays and less complex choice are more attractive to female fiddler crabs as they reduce search costs
(2017-02-01)
Females that quickly and accurately locate and assess males can reduce their risks of predation, dehydration and heat stress while mate searching. Here we measured the accuracy and time it took female fiddler crabs, Uca ...
Plasticity of parental care under the risk of predation: how much should parents reduce care?
(The Royal Society, 2013-08)
Predation can be an important agent of natural selection shaping parental care behaviours, and can also favour behavioural plasticity. Parent birds often decrease the rate that they visit the nest to provision offspring ...
Estimating discount rates for environmental goods: Are People’s responses inadequate to frequency of payments?
(2021)
Most stated preference studies estimate discount rates using a split-sample approach. Each sample faces a different payment frequency (for instance, 1, 5, 10) together with a
randomly assigned bid vector; both the frequency ...
Direct Connection of Supercapacitor-Battery Hybrid Storage System to the Grid-tied Photovoltaic System
(2018-08-30)
Penetration rate of grid-connected photovoltaic (PV) generation to the existing utility grid is rapidly increasing over the years. Since the power generated from PV systems fluctuate according to the weather condition, ...
