Atelopus eusebiodiazi

Atelopus eusebiodiazi is a species of toads in the family Bufonidae. It is endemic to northwestern Peru and only known from its type locality in Huamba, near Ayabaca, Piura Region.[1][3] The specific name eusebiodiazi honors Eusebio Diaz, taxidermist at the Museum of Natural History, Lima, and the collector of the holotype.[2]

Atelopus eusebiodiazi is only known from Huamba, in Piura Region, northwestern Peru.

Description

Atelopus eusebiodiazi is a relatively large Atelopus: adult males measure 36–41 mm (1.4–1.6 in) and females 43–47 mm (1.7–1.9 in) in snout–vent length. The head is longer than it is wide. There is no tympanum. The body is robust with relatively short limbs. The fingers are unwebbed whereas the toes have some webbing. Coloration of living specimens is unknown. In preservative, the dorsum is either chocolate brown with irregular black blotches and some yellowish cream blotches on flanks, or black with some irregular yellowish cream marks and a yellowish cream irregular dorso-lateral stripe. The venter is cream (sometimes with small black blotches), as are the palms and soles.[2]

Habitat and conservation

Atelopus eusebiodiazi lives in cloud forests at elevations of about 2,950 m (9,680 ft) above sea level. Specimens have been spotted in leaf litter and along small streams. Presumably, breeding takes place in fast-flowing streams.[1]

As of 2011, the species had last been observed in 1997—surveys in 2006 failed to find it. It is possible that it is extinct, although some potentially suitable habitat remains unsurveyed.[1][2] The type locality is threatened by habitat loss caused by increasing cattle grazing and agricultural land use.[1]

gollark: > There is burgeoning interest in designing AI-basedsystems to assist humans in designing computing systems,including tools that automatically generate computer code.The most notable of these comes in the form of the first self-described ‘AI pair programmer’, GitHub Copilot, a languagemodel trained over open-source GitHub code. However, codeoften contains bugs—and so, given the vast quantity of unvettedcode that Copilot has processed, it is certain that the languagemodel will have learned from exploitable, buggy code. Thisraises concerns on the security of Copilot’s code contributions.In this work, we systematically investigate the prevalence andconditions that can cause GitHub Copilot to recommend insecurecode. To perform this analysis we prompt Copilot to generatecode in scenarios relevant to high-risk CWEs (e.g. those fromMITRE’s “Top 25” list). We explore Copilot’s performance onthree distinct code generation axes—examining how it performsgiven diversity of weaknesses, diversity of prompts, and diversityof domains. In total, we produce 89 different scenarios forCopilot to complete, producing 1,692 programs. Of these, wefound approximately 40 % to be vulnerable.Index Terms—Cybersecurity, AI, code generation, CWE
