This Plain English fact sheet outlines the work done by the EPA in monitoring aquatic plants in Irish lakes.
Aquatic plants are good at showing if the quality of the water is good or bad and play an important role in lake ecology by providing food and a habitat for many smaller plants, animals and birds.
They also:
• provide shelter for young fish
• help to improve the clarity of the water
• help stabilise lake shore banks
• reduce the amount of sediment being suspended in the water
The Environmental Protection Agency (EPA) monitors these aquatic plants at more than 10,000 sites in over 200 lakes once every three years.

Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
2. Seagrasses
• Angiosperms (flowering plants) that live
life entirely underwater
• Primary productivity is among the highest
measured (500 - 4000 g C/m2/year)
• Important feeding and refuge habitat for
fishery species (shrimp, scallops, fishes)
• Seagrasses act as sediment stablizers help to
filter water

6. Habitat Complexity
• Habitat complexity is high in seagrass/SAV
• Predators are inhibited by complexity
because the prey have many places to hide
• Densities of many invertebrates (infaunal
and epifaunal) and small fishes are greater
in SAV than in nearby unvegetated areas
• Seagrass provides a refuge from predation
7. Types of animals in seagrass
• Infauna: bury in sediment.
– Polychaete worms, amphipods, clams, benefit from root and
rhizome mat which protects from predators
– deeper-living animals survive better than shallow-living
(Mercenaria > Chione)
• Epifauna: Live on surface of blades and sediment
– Meiofauna (harpacticoid copepods), macrofauna (amphipods.
isopods), tube-dwelling sessile polychaetes, gastropods, decapods
– Shoot and leaf complexity provides refuge
• Mobile fauna: Live in water over canopy
– fishes swim above canopy, dive into it when predator
