Coffee Grove Salamander

The Coffee Grove Salamander (Aquiloeurycea cafetalera) is a small, fully terrestrial plethodontid salamander in the family Plethodontidae, endemic to the cloud forests and coffee agroforestry zones of the Sierra de Juárez in the Mexican state of Oaxaca. Like all plethodontid salamanders, it is lungless, relying entirely on cutaneous gas exchange through its moist skin, making it exquisitely sensitive to desiccation and temperature changes. Adults are slender, with a reddish-brown dorsum and light-coloured venter, typically measuring 5–8 centimetres in total length. The species inhabits cool, humid cloud forest floor environments and the leaf litter and bark of shade-grown coffee plantations at elevations approximately between 1,500 and 2,500 metres—an association that gives it its common name. The presence of this salamander in coffee agroforestry systems highlights the biodiversity value of traditional shade-grown cultivation compared to sun-grown monocultures. The Coffee Grove Salamander is classified as Vulnerable by the IUCN due to its restricted distribution, estimated extent of occurrence below 5,000 square kilometres, and ongoing threats from habitat loss through deforestation, conversion to sun-grown coffee cultivation, and climate-driven changes to cloud forest conditions. No ex situ conservation programmes are known to be in place.

Common Spindle

<em>Euonymus europaeus</em>, commonly known as the common spindle, is a deciduous shrub or small tree in the family Celastraceae, native to Europe and western Asia. This species typically inhabits woodland edges, hedgerows, scrubland, calcareous grassland margins, and riverbanks, preferring well-drained soils on chalk and limestone but tolerating a variety of substrates. Its geographic range extends across most of Europe from the British Isles and Scandinavia south to the Mediterranean, and eastward through the Caucasus into western Asia. Classified as Least Concern on the IUCN Red List, <em>Euonymus europaeus</em> maintains stable populations throughout its native range. The species is particularly notable for its striking autumn display of bright pink to crimson four-lobed capsular fruits that split to reveal orange-coated seeds, providing an important food source for robins, blackcaps, and other birds. The seeds are toxic to humans and many mammals. The plant typically grows to 2–6 metres in height and produces small inconspicuous greenish-white flowers in spring. Biological traits such as average individual lifespan, precise body dimensions, and specific weight measurements remain poorly documented at the population level for this shrub. The hard, fine-grained wood has historically been used for making spindles and skewers, giving rise to the common name.
