Coimbra-Filho’s Titi

The Coimbra-Filho's Titi (Callicebus coimbrai), also known as Coimbra-Filho's Titi Monkey, is a small New World monkey in the family Pitheciidae, named in honour of the Brazilian primatologist Adelmar F. Coimbra-Filho. This titi monkey is endemic to the Atlantic Forest of northeastern Brazil, with its range restricted to the states of Sergipe and southern Alagoas—one of the most critically fragmented and threatened biomes on Earth. Adults are small, with reddish-brown fur on the flanks and upperparts, pale grey on the underparts, and an orange-red forehead band. Like all titi monkeys, Callicebus coimbrai is highly social, living in monogamous family groups of 2–5 individuals that engage in elaborate dawn duets and tail-twining behaviour as expressions of pair bonding. The species inhabits Atlantic Forest fragments, including lowland and highland forest patches, riverine gallery forest, and secondary growth, where it subsists on fruits, seeds, leaves, and occasional invertebrates. The Coimbra-Filho's Titi is classified as Endangered by the IUCN due to its severely fragmented range within one of the world's most deforested biomes, with less than 12% of original Atlantic Forest remaining, ongoing habitat loss from agricultural expansion, and small, isolated population sizes highly vulnerable to stochastic extinction events.

Common carpetgrass

<em>Axonopus fissifolius</em>, commonly known as common carpetgrass, is a grass species with a broad global distribution spanning Africa, Asia, Europe, the Americas, and Oceania. It typically thrives in grasslands, wetlands, forests, and cultivated areas, often tolerating poorly drained and low-fertility soils. Common carpetgrass belongs to the genus <em>Axonopus</em> within the family Poaceae. It is a low-growing, stoloniferous grass that typically forms dense mats along roadsides, disturbed areas, lawns, and pastures in warm and humid climates. The species is frequently used as a lawn and pasture grass in tropical and subtropical regions due to its tolerance of mowing and its ability to spread vegetatively. Biological traits such as average lifespan, plant height, and biomass of this species remain poorly documented in the scientific literature. The species has not yet been formally evaluated by the IUCN, and its global conservation status therefore remains undetermined. Its widespread occurrence across multiple continents and highly varied habitats suggests strong ecological adaptability.
