Climbing Bindweed

Climbing Bindweed, Calystegia sepium or related Convolvulus species in the family Convolvulaceae, is a vigorous twining perennial vine native to temperate regions of Europe, Asia, and North America, widely naturalized in disturbed habitats worldwide. The species climbs over hedgerows, fences, tall herbs, and shrubs by twining its flexible stems counterclockwise around supporting structures, sometimes smothering vegetation under dense leafy growth. The leaves are broadly arrow-shaped or hastate, and the funnel-shaped flowers are large, white to pale pink, and open during daylight hours. Like its relatives, Climbing Bindweed has deeply buried, extensively spreading rhizomes that are extremely difficult to eradicate once established. The extensive root system enables survival of herbicide treatments and mechanical disturbance, making the species a persistent weed in gardens, agricultural land, and riparian habitats. Despite its weedy character, the flowers provide nectar for bumblebees and are visited by hawk moths at dusk. The species is not threatened globally; it is considered common and often invasive across temperate regions. It has considerable cultural significance, appearing frequently in art and folklore as a symbol of persistence and entanglement.

Colombian Oldfield Mouse

<em>Thomasomys dispar</em>, commonly known as the Colombian Oldfield Mouse, is a small rodent species belonging to the genus <em>Thomasomys</em> within the family Cricetidae. This species is classified as Data Deficient, indicating that insufficient information is currently available to evaluate its conservation status with confidence. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Thomasomys</em> are typically associated with high-altitude Andean habitats, including páramo grasslands, shrublands, and montane forest edges, where they occupy ground-level microhabitats and burrow in soft soils. These mice are generally omnivorous, consuming seeds, plant material, and invertebrates, though specific dietary data for <em>Thomasomys dispar</em> have not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification highlights the need for targeted surveys in Colombian Andean regions to determine population size, distribution, and the ecological requirements of this poorly known rodent.
