common cow-wheat

<em>Melampyrum pratense</em>, commonly known as common cow wheat, is a semi-parasitic annual plant in the family Orobanchaceae. It is distributed across northern and central Europe, with occurrences recorded in Belgium, Denmark, Iceland, Norway, and Sweden, typically inhabiting ancient woodlands, heathlands, and species-rich grasslands. As a hemiparasite, common cow wheat attaches to the roots of neighboring plants via haustoria to obtain water and nutrients, while also conducting its own photosynthesis. It produces pairs of pale yellow tubular flowers with a closed mouth that are typically pollinated by bumblebees. The seeds of this species are attractive to wood ants, which disperse them through a process known as myrmecochory. <em>Melampyrum pratense</em> is assessed as Near Threatened on the IUCN Red List, reflecting ongoing habitat loss. Biological traits of this species remain poorly documented in the scientific literature.

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.
