Managing and adjusting the requirements and use of conserved forage

open access: yes, 2011
Forage harvesting and conservation must be properly managed in order to guarantee the quality of feed fed to the herd, keeping harvesting costs under control and ensuring the safety of the livestock farming system. In France, forage stores range between 1.2 and 3.5 kg DM/LU and vary according to the length of the growing season, herd size, and animal ...

Portuguese Students' Perceptions of Soil Ecosystem Services and Their Willingness to Change Behaviour for the Future of Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil is one of the most important non‐renewable natural resources, playing a vital role in sustaining humanity. Studies exploring how students perceive soil ecosystem services are considerably scarcer. Therefore, the main objectives of this study are: (i) to understand Portuguese students' perceptions of the importance of different soil ...

Computer Simulation to aid the Development, Transfer an Adoption of Alternative Forage Conservation Systems [PDF]

open access: yes
A computer simulation model of forage production, conservation and use was developed to evaluate forage technologies. The model simulates forage losses and quality changes along with the use and costs of machines, structures, labour, fuel, chemicals, etc.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Rapid methods of analysis of silages to improve feeding management in dairy farms

open access: yes, 2014
In modern dairy farms, optimization of feeding is critical to maintain animal health, lower impact and maximise profitability. However, large feed and forage variability reduce consistency of composition of diet delivered to dairy cows.

A simple index for assessing cumulative human impacts on mountain lakes

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Occurrence and conservation of the dugong (Sirenia: Dugongidae) in New South Wales

open access: yes, 2004
Recent sightings of dugongs well beyond the southern limit of their accepted range (~27°S) on the Australian east coast prompted a review of past records of dugongs and their current conservation status in New South Wales.
