Abstract This paper presents a model that simulates the size distribution and erosivity of raindrops throughfall drops. It utilizes existing models rainfall drop fall velocity combines them with newly collated evidence distributions. A sensitivity analysis reveals is sensitive to parameters are easily measured or estimated: intensity, mean volume diameter intercepted throughfall, canopy cover, height. The results may be used at two levels. Firstly, calculate specifically individual drops,...
Snakes lack both an outer ear and a tympanic middle ear, which in most tetrapods provide impedance matching between the air inner fluids hence improve pressure hearing air. would therefore be expected to have very poor generally insensitive airborne sound, whereas connection of bone jaw bones snakes should confer acute sensitivity substrate vibrations. Some studies nevertheless claimed that are quite sensitive vibration sound pressure. Here we test two hypotheses that: (1) (2) vibrations,...
Neuropeptide PDF (pigment-dispersing factor)-secreting large ventrolateral neurons (lLN v s) in the Drosophila brain regulate daily patterns of rest and arousal. These bilateral wake-promoting are light responsive integrate information from circadian system, sleep circuits, environment. To begin to dissect synaptic circuitry neural network, we performed simultaneous dual whole-cell patch-clamp recordings pairs lLN s. Both ipsilateral contralateral s exhibit synchronous rhythmic membrane...
Turtles, like other amphibious animals, face a trade-off between terrestrial and aquatic hearing. We used laser vibrometry auditory brainstem responses to measure their sensitivity vibration stimuli airborne versus underwater sound. Turtles are most sensitive sound underwater, depends on the large middle ear, which has compliant tympanic disc attached columella. Behind disc, ear is air-filled cavity with volume of approximately 0.5 ml resonance frequency 500 Hz underwater. Laser measurements...
Physiological and anatomical studies have suggested that alligators unique adaptations for spatial hearing. Sound localization cues are primarily generated by the filtering of sound waves head. Different vertebrate lineages evolved external and/or internal to enhance these cues, such as pinnae interaural canals. It has been hypothesized in alligators, directionality may be enhanced via acoustic coupling middle ear cavities, resulting a pressure difference receiver (PDR) mechanism. The...
Top-down attention increases coding abilities by altering firing rates and rate variability. In the frontal eye field (FEF), a key area enabling top-down attention, induced changes are profound, but its effect on different cell types is unknown. Moreover, FEF only cortical investigated in which does not affect variability, as assessed Fano factor, suggesting that task engagement affects state nonuniformly. We show putative interneurons of <i>Macaca mulatta</i> stronger attentional modulation...
Significance Attention improves perceptual abilities by modulating sensory processing. A key transmitter for attentional control is the neurotransmitter acetylcholine. We show that acetylcholine promotes signals in frontal cortex differentially activating 2 cholinergic receptor types different cell groups. Acetylcholine through muscarinic receptors specific subclasses of broad spiking cells. Moreover, it and nicotinic activation narrow Thus, eye field (FEF) are supported a highly...
Lungfishes are the closest living relatives of tetrapods, and ear recent lungfishes resembles tetrapod more than ray-finned fishes is therefore interest for understanding evolution hearing in early tetrapods. The water-to-land transition resulted major changes associated with detection air-borne sound pressure, as evidenced by late independent origins tympanic ears all groups. To investigate lungfish pressure vibration detection, we measured sensitivity frequency responses five West African...
One of the most challenging issues in Mediterranean ecosystems to date has been understand emergence discontinuous changes or catastrophic shifts. In era 2030 Sustainable Development Goals, which encompass ideas around Land Degradation Neutrality, advancing this understanding become even more critical and urgent. The aim paper is synthesise insights into drivers, processes management shifts highlight ways forward for ecosystems. We use a multidisciplinary approach that extends beyond typical...
Summary American mink (Neovison vison) kits are born altricial and fully dependent 40 on maternal care, for which the kits' vocalisations appear essential. We used Auditory Brainstem Recording (ABR) to determine (1) hearing sensitivity of adult females from two breeding lines known differ in behaviour (2) development 8-52 days age. also studied sound production 20 throughout postnatal 1 44. Adult female had a broad range kHz above 70 kHz, with peak (threshold dB SPL) at 8-10 no difference...
Reusing water and nutrients from municipal wastewater can conserve resources reduce treatment costs. In this study, the suitability of different qualities treated for plant production in a hydroponic flow-through system was investigated. Lettuce (Lactuca sativa L.) grown lines fed with wastewater, i.e., conventional effluent aerobic by activated sludge process (CE), ozonised CE (CEO), anaerobically pre-treated nitrified (AN) biological carbon filtered AN (ANC) comparison modified Hoagland...
Abstract. The Plynlimon headwater catchments in mid-Wales have been a landmark study of water resources the UK uplands for over 30 years. main physical features digitised as basis linking new model developments and process understanding. Examples are given how attributes related to land management, hydrology quality. These data also being used provide insights into catchment processes that may underpin development research. This work is particularly relevant need assessment status under...
To create a user-operated pure-tone audiometry method based on the of maximum likelihood (MML) and two-alternative forced-choice (2AFC) paradigm with high test-retest reliability without need an external operator minimal influence subjects' fluctuating response criteria. User-operated was developed as alternative to traditional for research purposes among musicians.Test-retest system evaluated compared audiometry.Test-retest 2AFC tested 38 naïve listeners. in 41 subjects.The repeatability...
Abstract Cognitive neuroscience has made great strides in understanding the neural substrates of attention, but our its neuropharmacology remains incomplete. Although dopamine historically been studied relation to frontal functioning, emerging evidence suggests important dopaminergic influences parietal cortex. We recorded single- and multi-unit activity whilst iontophoretically administering agonists antagonists while rhesus macaques performed a spatial attention task. Out 88 units, 50...
