Colombian spiny rat

<em>Proechimys canicollis</em>, the Colombian spiny rat, is a terrestrial rodent belonging to the diverse family Echimyidae, occurring in Colombia and Venezuela. Spiny rats of the genus <em>Proechimys</em> are among the most species-rich genera of Neotropical rodents, typically inhabiting lowland tropical and subtropical forests, forest edges, and secondary vegetation. The coarse, spine-like hairs that give this group its common name are thought to function as a deterrent against predators. <em>Proechimys canicollis</em> is assessed as Least Concern by the IUCN, suggesting stable populations across its range. This species likely feeds on seeds, fallen fruits, fungi, and invertebrates, and may play an important role as a seed predator and disperser in forest ecosystems. Research indicates that <em>Proechimys</em> species often achieve high local densities in undisturbed forest, making them important prey items for raptors, felids, and large snakes. Habitat loss in northern South America remains a background concern for long-term population stability. Biological traits of this species remain poorly documented in the scientific literature.

Common Orache

<em>Atriplex patula</em> is an annual herb in the family Amaranthaceae, distributed across Europe, Asia, North America, Australia, and Chile. It typically colonizes disturbed habitats, coastal areas, salt marshes, roadsides, agricultural fields, and waste ground, tolerating saline soils that many other species cannot withstand. The species is halophytic, possessing physiological adaptations for salt tolerance, including salt-excreting glands on its leaves. Its range extends across Georgia in Asia, thirteen European countries, and introduced populations in North America, Australia, and South America. Orache produces small, inconspicuous flowers and characteristic mealy-textured leaves. It is sometimes used as a leafy vegetable in traditional cuisine across parts of its native range. The IUCN lists this species as Least Concern given its widespread occurrence and adaptability to multiple habitat types. Biological traits including average lifespan, body measurements, and detailed dietary ecology remain poorly documented in standardized databases for this weedy annual species. <em>Atriplex patula</em> plays a functional role in stabilizing disturbed soils and contributing to coastal and ruderal plant communities across its broad distribution.
