The objectives of this study were to determine the diversity, seasonal dynamics and abundance of ticks infesting cattle in Isfahan zone, Iran. The study was conducted in three traditional cattle farms. No acaricides had been applied to cattle at the selected farms. Adult ticks were collected twice per month from different parts of the cattle's body. Environmental data, including relative humidi...

Net photosynthesis and stomatal conductance were measured in ten red spruce (Picea rubens Sarg.) saplings, growing near Ithaca, New York, throughout the early spring and late-fall growing periods. Gas exchange and daily minimum and maximum soil and air temperatures were also measured. Linear regression analysis showed that rates of net photosynthesis were positively correlated with both minimum...

Since the 1990s, phytoplankton biomass on the continental shelf of Nova Scotia and in the Labrador Sea has undergone sustained changes in the spring and fall, which are accompanied by changes in bacterioplankton that are dampened in amplitude but coherent in the direction of change. A reversal of trend in biomass change, so-called sign switching, occurs both in time and in space. Thus, whenever...

The Amur River is one of the largest rivers of the world. Its length is 4350 km and its total discharge is about 390 km from a river basin of 1,855,000 km. The regime of the Amur River is distinguished by the spring–summer flood, summer low water, summer– fall flood, and winter low water. The spring flood is caused by melting snow and the summer–fall flood is caused by monsoon rains in the rive...

Since its inception in 2010, the Linguistic Data Consortium’s data scholarship program has awarded no cost grants in data to 64 recipients from 24 countries. A survey of the twelve cycles to date – two awards each in the Fall and Spring semesters from Fall 2010 through Spring 2016 – yields an interesting view into graduate program research trends in human language technology and related fields ...

Abstract We examined dietary preferences of wild pigs to discern possible bait alternatives corn. Captive trials were conducted during spring and fall 2021 in the Wild Pig Research Facility at Kerr Wildlife Management Area, Hunt, Texas, USA. 2‐choice tests by allowing feed ad libitum on soybeans, split peas, mealworms, peanuts (spring 2021), oats, acorns, earthworms, (fall always with corn avai...

A spring-fall asymmetry is observed in daytime amplitude values of very low frequency (VLF) radio wave signals propagating over the North Atlantic during 2011–2019. We explore processes behind this by comparing against mesospheric mean temperatures and semidiurnal solar tide (S2) winds. The radiation influence on VLF subionospheric propagation was removed from values, isolating fall-effect. Sim...

We tested the hypotheses that management of the soil food web in the fall would enhance grazing on bacteria and fungi by microbivorous nematodes in the spring, consequently increasing N availability in cover-crop driven organic and low-input farming systems. The food web was manipulated by irrigating the dry soil of late summer and/or providing carbon sources. By creating conditions conducive f...
