Ecuador is one of the most biodiverse countries in the world, but faces severe pressures and threats to its natural ecosystems. Numerous species have declined and require to be objectively evaluated and quantified, as a step towards the development of conservation strategies. Herein, we present an updated National Red List Assessment for amphibian...

Comprehensive assessments of species’ extinction risks have documented the extinction crisis and underpinned strategies for reducing those risks. Global assessments reveal that, among tetrapods, 40.7% of amphibians, 25.4% of mammals and 13.6% of birds are threatened with extinction. Because global assessments have been lacking, reptiles have been o...

We describe a new species of Linothele Karsch, 1879 from the southeastern slopes of the Andes in Ecuador. The new species can be distinguished from all congeners by the presence of abundant bright whitish-golden curly setae on the carapace; a pattern-less grey abdomen in adults, with short whitish-golden setae, short black setae and long and erecte...

Harmonia axyridis is a ladybird extensively used around the world for biological control of agricultural pests. However, it has become invasive in several countries, producing negative ecological and socio-economic impacts. Herein, we review the invasion history of the Harlequin Ladybird Harmonia axyridis (Pallas, 1773) in Ecuador. Although first r...

The Galapagos Archipelago has been world-famous since Darwin’s visit and is recognized for its species radiation and high levels of endemism. However, Galapagos snakes of the genus Pseudalsophis remained poorly known until recently. The taxonomy of this snake radiation was in turmoil until 2018, when nine species were recognized and its origin and...

Studies on genetic variability amongst native and introduced species contribute to a better understanding of the genetic diversity of species along their autochthonous distribution and identify possible routes of introduction. Gonatodes caudiscutatus is a gecko native to western Ecuador and introduced to the Galapagos Islands. Despite being a succe...

The marine iguana populations of San Cristóbal are the smallest of any island in the archipelago and are regarded as the highest priority for the conservation of the species. Marine iguanas depend on their tail for swimming and diving to get food while submerged, and tail damage may impact their ability to forage efficiently. We present the first t...

We describe two new species of glassfrogs of the genus Centrolene living in syntopy at La Enramada, province of Azuay, southwestern Ecuador. They were found in a small creek in montane evergreen forests at 2,900 m elevation. The first new species is distinguished from all other members of the genus Centrolene by having the following combination of...

We present the first record of Holothele longipes (L. Koch, 1875) (Araneae, Theraphosidae) from the Republic of Ecuador, based on a male specimen collected near Puerto Misahuallí, province of Napo, in the north-eastern foothills of the Andes, upper River Napo basin. This new record extends the geographic range of H. longipes by approximately 554 km...

We review the distribution of White-cheeked Pintail (Anas bahamensis rubrirostris) in mainland Ecuador and show that the species has expanded its range significantly. Contrary to published records, A. b. rubrirostris has been present in mainland Ecuador at least since the early 20th century, although probably in low numbers. During the 20th century...

Recent surveys in the Río Negro-Sopladora National Park revealed a striking new species of Hyloscirtus . The new species is easily diagnosed from all other congeners by its large body size (64.9 mm SVL in adult female); broad dermal fringes in fingers and toes; prepollex not projected into a prepollical spine and hidden under thenar tubercle; dorsu...

Tropical dry forests are among the most threatened and yet the most biodiverse Neotropical ecosystems. However, current patterns of biological occupancy in these forests remain poorly studied. Here, we document the diversity, patterns of seasonal turnover and change of species composition over time of birds in a highly exploited but protected tropi...

Visual communication is apparently widespread among anurans, but these behaviours in many Neotropical species remain unstudied. We provide the first descriptions of visual displays in males of the Neotropical treefrog Dendropsophus carnifex (Hylidae) from three populations at Mindo, in northwestern Ecuador. We describe hind-foot lifting, foot-flagg...

We have discovered a spectacular new species of frog in the genus Hyloscirtus, belonging to the H. larinopygion species group. The adult female is characterized by a mostly black body with large bright red spots on the dorsal and ventral surface, extremities, and toe pads. The adult male is unknown. Small juveniles are characterized by a yellow bod...

Helminths are not usually considered important pathogens for birds of prey. There is a single published report of mortality in raptors due to an air sac trematode infection. We report a well-documented death case from massive infection by an air sac trematode of the family Cyclocoelidae in a wild-caught, juvenile male Snail Kite (Rostrhamus sociabi...

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban...

In this work, we propose a ladybird beetle detector based on a deep learning classifier and the weighted Hausdorff distance as a loss function. The detector was trained and validated using a ten-fold cross-validation method on a database composed of 2,633 wildlife images with ladybird beetles. Despite the detector performance was assessed using fou...
