This document defines and describes biodiversity as the variability among living organisms, including genetic diversity within species, diversity of species, and diversity of ecosystems. It provides examples of genetic diversity within species like different fur colors in rabbits. It notes there are over 1.8 million classified species, with arthropods making up over half, and estimates of total species ranging from 8.7 to 2.2 million undiscovered species still remain. Ecosystem diversity is defined as the variability in structure, function, and dynamics of communities of living and non-living interactions within an environment.

Importance of study of immature stages of insects in agricultureSanju Thorat
The type of life cycle will vary with the insect-pest. However, most pests have certain weak points during their life cycle when they are the most vulnerable to manage. Some insect are predators, either as larvae or in both larval and adult stages. The decomposition of organic waste, such as dung and manures are an important ecosystem process which is largely provided by insects. Insect as food for animals and human being. The knowledge regarding immature stages of insect-pests and understand site of oviposition, site of pupation and larval behaviour can allow for timely and effective management, thus we can reduction in the qualitative and quantitative losses of yield and increase the profit.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Editor's Notes
Zea mays: large grain plant domesticated by indigenous peoples in Mesoamerica in prehistoric times. The leafy stalk produces ears which contain the grain, which are seeds called kernels. Maize kernels are often used in cooking as a starch. The six major types of maize aredent, flint, pod, popcorn, flour, and sweet. Prior to their domestication, maize plants only grew small, one-inch long corn cobs, and only one per plant. Many centuries of artificial selection by the indigenous people of the Americas resulted in the development of maize plants capable of growing several cobs per plant that were usually several inches long each. They are of various colors: blackish, bluish-gray, purple, green, red, white and yellow. When ground into flour, maize yields more flour with much less bran than wheat does. It lacks the protein gluten of wheat and, therefore, makes baked goods with poor rising capability. A genetic variant that accumulates more sugar and less starch in the ear is consumed as a vegetable and is called sweet corn. Young ears can be consumed raw, with the cob and silk, but as the plant matures (usually during the summer months), the cob becomes tougher and the silk dries to inedibility. By the end of the growing season, the kernels dry out and become difficult to chew without cooking them tender first in boiling water.
Lucanus cervus: Ciervo volante. Greatest beetle in Europe. Su tamaño total varía entre los 3 y 9 cm en los machos y los 2,8 y 5,4 cm en las hembras. Presentan un notable dimorfismo sexual; los machos son mayores que las hembras y poseen las mandíbulas mucho más desarrolladas que utilizan para la lucha; tienen una forma que recuerda los cuernos de un ciervo, de donde deriva su nombre común.
Copris hispanus: Escarabajo rinoceronte. Dichos cuernos están, en general, mucho más desarrollados en los machos, ya que los utilizan en sus luchas para conseguir pareja.
Leptinotarsa decemlineata: Escarabajo de la patata. L. decemlineata es una importante plaga sobre todo en el cultivo de patata. También puede ocasionar daños en plantas de tomate y de berenjena. Tanto las larvas como los adultos se alimentan de las hojas y pueden llegar a eliminar totalmente las plantas. Losinsecticidas son actualmente el principal método de control de este escarabajo en plantaciones comerciales. Sin embargo, muchos insecticidas no producen un buen resultado en su control debido a la resistencia a los tóxicos de esta especie y a la rapidez con la que pueden desarrollar resistencia a ellos. Esta especie ha desarrollado resistencia a la mayoría de los insecticidas normalmente utilizados.
La gran fecundidad de esta especie, normalmente le ayuda a soportar la presión de sus enemigos naturales. Aun así, en determinados casos, sus enemigos naturales pueden mantener las poblaciones de L. decemlineta bajas, de modo que los daños económicos causados no sean elevados. Beauveria bassiana es un hongo patógeno que puede infectar a un amplio rango de insectos incluyendo L. decemlineta. Es probablemente el enemigo natural más ampliamente utilizado en su control, presentándose en formulaciones comerciales que permiten que pueda ser utilizado en los equipos convencionales de tratamientos agrícolas
Chrysomela menthastri: Escarabajo de la menta.
Gannets hunt fish by diving from a height into the sea and pursuing their prey underwater. Gannets have a number of adaptations which enable them to do this:
no external nostrils, they are located inside the mouth instead;
air sacs in the face and chest under the skin which act like bubble wrapping, cushioning the impact with the water;
positioning of the eyes far enough forward on the face for binocular vision, allowing them to judge distances accurately. Gannets can dive from a height of 30 metres (98 ft), achieving speeds of 100 kilometres per hour (62 mph) as they strike the water, enabling them to catch fish much deeper than most airborne birds.
The gannet's supposed capacity for eating large quantities of fish has led to "gannet" becoming a disapproving description of somebody who eats excessively, similar to "glutton".
About 1,200 pairs of gannets nest in Muruwaivhere from August to March each year
