Common Speckled Bush-cricket

<em>Leptophyes punctatissima</em>, commonly known as the common speckled bush cricket, is a medium-sized bush cricket in the family Tettigoniidae, widespread across Europe and parts of western Asia. This species typically inhabits hedgerows, woodland edges, bramble patches, tall herbaceous vegetation, and gardens, where dense leafy cover provides both shelter and food. It is distributed from the British Isles and Scandinavia south through continental Europe to the Mediterranean basin and eastward into parts of the Middle East. Classified as Near Threatened on the IUCN Red List, <em>Leptophyes punctatissima</em> faces pressures from agricultural intensification, loss of hedgerow habitats, and changes in vegetation management. The species is primarily herbivorous, typically feeding on the leaves and flowers of a variety of plants including bramble, raspberry, and other soft-leaved shrubs and herbs. Adults are typically green with fine black speckles, and females possess a distinctively long, curved ovipositor used to deposit eggs into plant tissue. Calling songs are produced at ultrasonic frequencies largely inaudible to humans. Biological traits such as average lifespan in years, body length measurements, and body weight remain poorly documented at the population level, though adults are typically present from midsummer through autumn before dying off as temperatures drop.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
