Summary
This review explores temperate pasture forage selection, advocating for functional trait diversity over species richness. A science-based framework helps farmers select complementary species for resilient, productive pastures.
Area of Science:
- Pasture management
- Forage plant science
- Agricultural ecology
Background:
- Historical shift from diverse meadows to simplified perennial ryegrass pastures.
- Renewed interest in diverse pastures due to climate change and environmental pressures.
- Challenges in applying research to commercial grazing and ensuring transferability.
Purpose of the Study:
- To review the evolution of temperate pasture forage selection.
- To propose a science-based framework for selecting diverse pasture systems.
- To guide farmers in optimizing pasture productivity and resilience.
Main Methods:
- Historical review of forage plant selection practices.
- Analysis of current drivers for pasture diversity (climate change, environment, market).
- Proposal of a framework prioritizing functional trait diversity.
Main Results:
- Functional trait diversity is more impactful than species richness for pasture benefits.
- Existing forage selection tools have limitations for diverse pastures and holistic objectives.
- A pragmatic framework guides selection based on objectives, constraints, and site-specific conditions.
Conclusions:
- Strategic selection of complementary species and cultivars enhances pasture function.
- Future decision-support tools need to integrate resilience, ecosystem services, and management.
- Co-development of tools with stakeholders is crucial for practical and economic viability.

00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
01:28Methods of Medium Optimization
Optimizing growth media enhances microbial proliferation and maximizes product yield. Statistical experimental design methodologies provide structured and reproducible approaches, offering progressively higher levels of robustness and efficiency.The One-Factor-at-a-Time (OFAT) MethodThe One-Factor-at-a-Time (OFAT) method involves adjusting a single variable while keeping all others constant. However, it cannot detect interactions between variables, often leading to suboptimal outcomes when...
01:22Bioreactor Controls-III
Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
