Geographic distribution and habitat use of Lepidoblepharis miyatai (Squamata: Sphaerodactylidae), with comments on the taxonomic status of the genus in northern Colombia. We present some ecological and biogeographic data on Lepidoblepharis miyatai, a small and endangered gecko endemic to the northwestern foothills of the Sierra Nevada de Santa Marta (SNSM), 31 years after its description. Based on museum specimens and feld observations, we recorded four new localities with confrmed presence of L. miyatai. We calculated the extent of occurrence and altitudinal distribution of this species reaching 21.3 km2 and from sea level to 360 m respectively. Lepidoblepharis miyatai inhabits plant formations of scrub thorn and tropical deciduous forest. Based on microhabitat data obtained from 88 individuals observed in “Las Tinajas Village” we can state a differential use of three substrates with predominant use of leaf-litter. We consider L. miyatai an endemic species of the northwestern sector of the SNSM with a distribution range limited to the south-west by the occurrence of L. sanctaemartae, and towards the east by a thus far undetermined Lepidoblepharis species (here called Lepidoblepharis cf. sanctaemartae). We do not register sympatry of L. miyatai with any other congener. Accordingly, we consider that the recent records of this species in the southeast sector of SNSM are erroneous, given that the specimens cited as L. miyatai of this zone correspond to Lepidoblepharis cf. sanctaemartae. Finally, a reevaluation of the conservation status of L. miyatai is needed, including precise information of its distribution.

The flora of Irapuato has been poorly explored, because it is an area dedicated to agriculture and there are few strains of tropical deciduous forest and subtropical scrubland. The objectives of the study were to know the floristic composition in Cerro del Veinte, compare the richness of species with other locations that have the same type of vegetation and determine the conservation status of the species according to NOM-059 SEMARNAT-2010. The sampling was through free transects of approximately 1 km in the Barrancas La Escondida and El Paiste. A total of 59 families, 137 genera, 171 species and four varieties were obtained. The best represented families are Asteraceae, Fabaceae and Pteridaceae. According to the Chao 2 estimator, the sampling effort in the study area was 87%. Floristic affinity in Cerro del Veinte was greater with the Hoya de Rincón de Parangueo (38%) and Sierra de Pénjamo (32%). In addition, there are three new species reported for Guanajuato, Govenia lagenophora and Sacoila lanceolata (Orchidaceae) and Solanum edmundoi (Solanaceae). The taxa Cedrela odorata and Erythrina coralloides are included in NOM-059-SEMARNAT-2010.

Pseudogonatodes furvus is an endemic gecko from the region of the Sierra Nevada de Santa Marta, an isolated massif located in the continental Caribbean region of Colombia. Pseudogonatodes furvus is the type species of the genus, and its morphology and natural history remain poorly known. This lizard was described based on two specimens. After its description, the species has only been mentioned in a handful of taxonomic studies of Pseudogonatodes, in which a few morphological characters of P. furvus have been mentioned. One other paper reported two new localities, without providing new information on the external morphology, especially the lepidosis of the newly obtained specimens. Here we review the external morphology of P. furvus, based on examination of the holotype and six additional specimens. We provide an extended diagnosis and definition, description of holotype, variation, comparisons with other Pseudogonatodes, geographic distribution (adding a fourth locality to the known distribution for the species), and conservation status. Additionally, we describe osteological features for the diagnosis of the genus.

Red-knobbed coot, Fulica cristata, was formerly distributed across several countries in the south-west Palaearctic. Remnant populations are now located in Morocco and Spain. In the latter, the red-knobbed coot is considered critically endangered, and its decline is attributed to changes in agricultural practices in the basins of wetlands, which have affected the quality and quantity of food. However, red-knobbed coot is currently more abundant in Morocco. Foraging behaviour reveals information about an animal’s perception of the place that it currently occupies. Thus, we hypothesised that if habitat quality is lower in Spain than in Morocco, this should be expressed in the foraging activity of coots, which should be greater in Spain to compensate for the lower food availability. Our results supported this prediction: red-knobbed coots spent more time foraging in Spain than in Morocco. Furthermore, we compared the foraging behaviour of red-knobbed and common coots, Fulica atra, in southern Spain, where common coot does not face conservation problems, and found that red-knobbed coots spent more time foraging than common coots to meet daily energetic needs. Overall, our results suggested that constraints of food quality and quantity on habitat use were more severe for red-knobbed coots than for common coots, and that this may be a key factor for the conservation of red-knobbed coot in Spain. Managers should try to facilitate longer hydroperiods in wetlands, which would ensure higher quality food during longer periods for coots.

Biogeographical endemism and habitat restriction are two easily measured quantities that can be used as indicators of species' ecological restrictions. We analysed and compared these two types of information from available literature sources in an attempt to identify all bird species critically dependent on tropical deciduous forests of western Mexico and Central America. Based on patterns of biogeographical restriction, we identified 42 endemics, 33 disjunct endemics, 59 corridor species and 3 seasonal endemics associated with tropical deciduous forest (TDF) in this region. Based on patterns of habitat use in these species, we classified them as 50 tropical deciduous forest-restricted species and 82 apparent habitat generalist species. No habitat use information was available within the TDF belt for five of the biogeographically restricted species. We found a high proportion of apparent habitat generalists (60%) among biogeographically restricted species. We discuss three specific scenarios in which species critically dependent on TDF may nonetheless appear generalized in their patterns of habitat use. These species are termed “cryptic habitat specialists.” The proportion of apparent habitat generalists is highly variable among biogeographical regions and habitat types. Thus, global biodiversity conservation prioritizations that rely on habitat restriction as an indicator of ecological sensitivity may underestimate conservation needs within bioregions that contain high proportions of cryptic habitat specialists.

The geographic distribution of Bokermannohyla lucianae, know only from its type locality in the municipality of Una, is extended 60 km south and 60 km south-west with two new localities in southern Bahia. The species seems to be restricted to remnants of primary and secondary Atlantic Rainforest patches in a small area of southern Bahia.

We provide information on the distribution, natural history, and conservation status of Nymphargus mixomaculatus (Guayasamin, Lehr, Rodriguez & Aguilar, 2006), a species from central Peru which is currently considered as Critically Endangered. We report four new localities and extend the altitudinal distribution by 430 m and the geographic range by 513 km in a straight line northwest of the previous, only known locality. Furthermore, based on our new data and following the criteria and categories of the International Union for Conservation of Nature, we suggest that N. mixomaculatus should be recategorized as Vulnerable.

Despite being one of the smallest states in Mexico, the high diversity of habitats in Morelos has led to the development of a rich biota made up of a mixture of species typical of the Neovolcanic Axis and the Sierra Madre del Sur. However, recent expansion of cities in Morelos is likely to have consequences for the state’s herpetofauna. Here a checklist of the amphibians and reptiles of Morelos is provided with a summary of their conservation status and overlap with its neighboring states. Morelos is home to 139 species of amphibians and reptiles representing 32 families and 75 genera. Twenty-six of the 38 species of amphibians and 70 of the 101 species of reptiles that inhabit Morelos are endemic to Mexico. Fourteen species of amphibians and reptiles from Morelos are IUCN listed (i.e., Vulnerable, Near Threatened, or Endangered), 22 are placed in a protected category by SEMARNAT, and 41 are categorized as high risk by the EVS. The Tropical Deciduous Forest vegetation type hosts the greatest number of amphibian and reptile species in Morelos (84 species). Morelos shares the largest proportion of its herpetofauna with the State of Mexico (79.3%), Puebla (77.0%), and Guerrero (74.8%).
