THE EFFICIENCY OF SELECTION FOR SEED YIELD IN THE FAHL VARIETY OF EGYPTIAN (BERSEEM) CLOVER, Trifolium alexandrinum L. [PDF]

Journal of Plant Production, 2007
Two cycles of modified mass selection and one cycle of family selection were applied on a population of the Fahl variety of Egyptian clover. In 2003/2004, two hundred plants (5% selection intensity) were selected for seed yield, using the modified mass ...

Breeding limits foraging time: evidence of interrupted foraging response from body mass variation in a tropical environment [PDF]

Journal of Avian Biology, 2017
Birds should store body reserves if starvation risk is anticipated; this is known as an ‘interrupted foraging response’. If foraging remains unrestricted, however, body mass should remain low to limit the predation risk that gaining and carrying body reserves entails.

Forage intake processes by goats on a massai grass pasture with different sward heights

Semina: Ciências Agrárias, 2016
The objective of this study was to evaluate the forage-intake process of goats feeding on Massai grass pastures with different heights (40, 50, 60, and 70 cm). The experimental design was completely randomized, with treatments corresponding to four sward

To eat and not be eaten: diurnal mass gain and foraging strategies in wintering great tits [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2018
Adaptive theory predicts that the fundamental trade-off between starvation and predation risk shapes diurnal patterns in foraging activity and mass gain in wintering passerine birds. Foragers mitigating both types of risk should exhibit a bimodal distribution (increased foraging and mass gain early and late in the day), whereas both foraging and mass ...

How Are Warm-Season Pastures’ Nutritive Value and Fermentation Characteristics Affected by Open Pasture, Silvopasture, and Sward Herbage Maturity?

Agronomy, 2023
This study aimed to evaluate the forage mass and nutritional value (NV) of Guinea Massai grass (Megathyrsus maximus × Megathyrsus infestum) in an open pasture (OP) or the silvopastoral system (SPS) at different stages of development (SDs).
