Since many bat species thrive in densely vegetated habitats, echoes from foliage are likely to be of prime importance to the animals' sensory ecology, be it as clutter that masks prey echoes or as sources of information about the environment. To better understand the characteristics of foliage echoes, a new model for the process that generates these signals has been developed. This model takes ...

thirty five growing male goats (6.98±0.86 kg bw) were divided into five equal groups with seven animals in each group. the five dietary treatments were consisted of varying proportions of moringa foliage (moringa oleifera) and napier grass (pennisetum purpurium); t1 (100% moringa foliage); t2 (75% moringa foliage+25% napier grass); t3 (50% moringa foliage+50% napier grass); t4 (25% moringa foli...

Introduction In Finland, the forest canopies are the main source of the volatile organic compounds (VOC). These forests are representative of the boreal ones, and they cover about 80% of the total land area of the territory of Finland. The forests throughout the country are utilised commercially and managed regularly with the consequence that the natural tree species composition is much affecte...

Thirty five growing male goats (6.98±0.86 kg BW) were divided into five equal groups with seven animals in each group. The five dietary treatments were consisted of varying proportions of Moringa foliage (Moringa oleifera) and napier grass (Pennisetum purpurium); T1 (100% Moringa foliage); T2 (75% Moringa foliage+25% napier grass); T3 (50% Moringa foliage+50% napier grass); T4 (25% Moringa foli...

Net photosynthetic rates of developing foliage and one-year-old foliage of loblolly pine (Pinus taeda L.) were measured under field conditions. In the subsequent year, net photosynthesis and dark respiration rates of current-year and one-year-old foliage were measured under controlled environmental conditions. Loblolly pine foliage grows slowly, reaching its final size 3.5 to 4 months after bud...

Estimation of coherent and incoherent radio frequency (RF) signal attenuation through foliage is of great importance for a number of radar and communication problems. At UHF band and higher frequencies foliage presents a complex environment for electromagnetic waves in terms of scattering and wave propagation. For most applications, dealing with complex foliage models that account for single an...

Gas exchange was measured on a pruned Pinus radiata D. Don hedge and on a long-branch P. radiata tree near Hamilton, New Zealand, in spring 1993 when soil water content was close to field capacity. Foliage at the end of long branches (9.0 m) showed a marked drop in net photosynthetic rate and stomatal conductance as the saturation deficit increased, whereas foliage on short branches (0.5 m) sho...

We investigated how host plant phenology and plant species affected longevity, reproduction, and feeding behavior of an invasive weevil. Phyllobius oblongus L. (Coleoptera: Curculionidae) is common in northern hardwood forests of the Great Lakes Region. Adults emerge in spring, feed on foliage of woody understory plants, and oviposit in the soil. Preliminary data indicate that adults often fee...

Eight male cattle of Local Yellow breed with an average live weight of 121 kg and an average age of 18 months were used to evaluate the effects of different levels of sun-dried cassava foliage supplementation (Manihot esculenta) on intake, digestibility and N retention. Rice straw ad libitum and para grass (Brachiaria mutica) at 1% DM of BW comprised the basal diet. The study was arranged as a ...
