This study investigated the sublethal effects of salinity on four macroinvertebrate species commonly occurring in Australian freshwater ecosystems. These were; the introduced worm Lumbriculus variegatus Müller (Annelida: Oligochaeta), the introduced snail Physa acuta Draparnaud (Gastropoda: Physidae), the shrimp Paratya australiensis Kemp (Decapoda: Atyidae) and the midge Chironomus tepperi Skuse (Diptera: Chironomidae). The effects of salinity on growth, development and reproduction of these species were investigated through a series of laboratory tests.

Source and sink activity measured after anthesis in six poplar rice cultivars. The experiment was laid in randomized block design with six cultivars MTU-1001, MTU1010, MTU-7029, BPT-2231, BPT-3291 and BPT-5204 replicated four times. After anthesis, top three leaves separately, top three internodes collectively, panicle axis and grain of main culm were sampled at seven day interval and analysed for biochemical parameters that serve remobilization of nutrients. During the initial and later halves of the sampling, there was a shift in higher amylase activity from third to flag leaves.

Present study was conducted to explore the effect of milking temperament on milking attributes like milk let down time, milking time, milk flow rate, milk yield, composition in relation to plasma cortisol level and reproductive performance in Sahiwal cows. The experiment was carried out on 88 lactating healthy Sahiwal cows in hot- humid (38) and winter (58) season. The milking temperament was scored and the cows were grouped as docile and restless.
