Here we report two cases of defensive behavior known as "stiff-legged", unprecedented for the species Rhinella bergi and R. mirandaribeiroi. We registered the behavior at localities in Mato Grosso do Sul and Minas Gerais states, Brazil. With our records, there are now five species from open areas that exhibit this behavior. We assume that the species that inhabit these areas exhibit this avoiding predation behavior simulating a dead body on the ground, behavior known as "death feigning", unlike forest species, which use this strategy to camouflage themselves between the leaves.

Colicodendron scabridum, commonly known as “sapote”, is one of the most common woody species in seasonally dry neotropical forests, and an important food for numerous animals. We investigated sapote’s reproductive phenology and evaluated its relationship to temperature and precipitation. To do so, we installed seven 2 m x 300 m transects, each with fifteen focal individual sapote trees, at seven sites from 257 – 353 m at Cerro Venado, Lambayeque, Peru. The duration of flowering and fruiting varied among individuals, sites, and years. On average, 85-97 % of individuals with flowers bore fruit. The average fruiting period was shorter than the average flowering period, which it followed three months later. We used a cross correlation test to evaluate the relationship between flowering, and fruiting, with the monthly average temperature and precipitation. Sapote flowering changed in opposition to monthly average temperature, with a strong inverse correlation between flowering and temperature. In contrast, the frequency of individuals with fruits was positively correlated with temperature. There was no relationship between monthly precipitation with either flowering or fruiting. Our results suggest that temperature may determine when the species reproduces, thus affecting food availability for wildlife. The phenological variations we recorded are relevant to decisions for the conservation of this species.

Quillaja saponaria is a sclerophyllus evergreen tree species distributed from 30° to 38° S in Central Chile. In this wide distribution it is expected that the species exhibits phenotypic plasticity in the morphology of leaves associated to climate variation; however, the information on this topic is still scarce. We studied leaf phenotypic variation and its relationship with temperature, precipitation, and aridity in 85 stands of Q. saponaria throughout the natural distribution of the species. The results show that the basal diameter of petiole, the number of secondary veins, and the basal diameter of the principal vein increased with precipitation and decreased with aridity, while the length, basal diameter and the relative length of the petiole decreased with temperature. This confirms that phenotypic variation for foliar characters in Q. saponaria is related to climatic variables indicating an adapting capability of the species to the wide range of environmental conditions in which grows.

Jose Celestino Mutis, mostly known for his contributions in the botanical field, however; made significant, if little known, scientific additions in fields from mathematics to zoology. In this paper, I present to the public, for the first time, Mutis’ works on ichthyology in the Viceroyalty of New Granada, colonial Spanish title for the northern part of South America including the current countries of Panama, Colombia, Venezuela, and Ecuador, works that, as Linnaeus himself proposed, will be immortalized.

In a degraded ecosystem, which is currently under restoration, detailed analysis of their vegetation structure and descriptions of its association with bird species are very useful for its habitat management. Architecture analysis is a visual method for describing vegetation and plant structure as result of their growth strategy. Based on this method, habitat offer for three insectivorous bird species Myrmeciza longipes (White-bellied Antbird), Thamnophilus doliatus (Barred Antshrike) and Synallaxis albescens (Pale-breasted Spinetail) was analyzed as part of their population analysis and habitat quality evaluation in a fragment of tropical dry forest of 11 079 hectares, Huila, Colombia. By mean of counts and also through the secondary information collected, we gauged how these bird species uses the different vegetation strata. Taking into account that trees with more perches increases insectivorous birds forage, that more perches built on more bird refuges, and also that more crossing perches make up more forks for these species nests. In 186 plots of a tropical dry forest zone we determined that the area was dominated by seven architecture models which were divided into three groups according to their potential offer of habitat resources for the three species: 1) architectural models Roux, Petit, and Pervost that offer high quality 2) architectural models Noriba and Nozeran with intermediate quality; and 3) architectural models Mc Clure and Hottum, with very low quality.

The absence of public protected areas in Casanare Colombia has led to strengthen conservation processes by private reserves (RNSC), where working together with local communities is the basis of biodiversity management. This study aimed to evaluate the richness and abundance of terrestrial mammals through a community-based monitoring program. During two seasons (2018 and 2019), eleven camera traps were installed, for a total of 960 camera-days. Eighteen mammal species were recorded, belonging to ten families and six orders, including the two threatened species Myrmecophaga tridactyla and Pteronura brasiliensis. This study is one of the first mammalian inventories in the Colombian Orinoco based on a community exercise of biodiversity knowledge.

The Mammal Collection “Alberto Cadena Garcia” of the Instituto de Ciencias Naturales has specimens of great heritage and biological value for the knowledge of Colombian mammals, which is specified through the availability of information associated with these specimens and its relevance for teaching, research in different areas and access to information by the general public. To uncover the impact that the Collection has had, the taxonomic, geographical and temporal representativeness of the specimens was examined by analyzing the information associated with them and review of literature related to their use. The Collection has specimens of all orders of Colombian mammals, 80.5 % of the species reported for Colombia, and specimens for all departments of the country. On the other hand, the Collection has also contributed to the training in mammalogy of numerous undergraduate Biology students, in the development of 167 undergraduate and thesis projects on various topics, more than 100 publications in recent years, and the visit of 190 researchers, nationals and foreigners, in the last ten years. Given the impact that the Collection has, it is important to strengthen the processes of dissemination of information and search for alliances so that the Collection continues to contribute to the knowledge of the diversity of mammals in the country.

The PNN Selva de Florencia, in the central Andes of Colombia, is reservoir of a large biodiversity including five species of primates. Despite being a protected area, there are anthropic transformation processes that directly affect their ecosystems. Currently, we do not have quantitative models that allow us to estimate the effect of these transformations on primate populations. We evaluated the proportion of the area used (ψ), as an abundance estimation of the primates Ateles hybridus, Alouatta seniculus, and Cebus versicolor. Our methods included random sampling in 31 plots of 1 km2, where we evaluated i) primate presence; ii) human presence; as well as the percentage of: iii) plantations; iv) pastures; and v) natural coverage, using a 1:25 000 Corine Land Cover map, adapted to Colombia. We followed a Bayesian approach to analyze our dataset. We report a ψ of 0.16, and 0.14 detection probability for A. hybridus, with a decreasing area use in forest; a ψ of 0.83, and detection probability of 0.14 for A. seniculus, with a decreasing area use in plantations; finally, we estimated a ψ of 0.36, and 0.08 detection probability for C. versicolor, with a decreasing area use in plots with human presence. Data in our work can be used as input for the design and implementation of effective monitoring in this protected area.

Nuestro objetivo fue explorar la representatividad de mamíferos en la IAvH-CSA y promover su uso entre la comunidad mastozoológica colombiana. Encontramos 129 registros, la mayoría de Primates. Los registros incluyen representación de todas las regiones geográficas, excepto el Catatumbo, y 21 de los 32 departamentos del país. Aun así, solo el 3 % de las especies de mamíferos de Colombia están representadas en la colección. Éstas han sido grabadas en su mayoría por ornitólogos. Por tanto, hacemos un llamado a apoyar los repositorios públicos en nuestro país, depositar los registros acústicos para garantizar accesibilidad a estos y abordar futuras preguntas en la bioacústica de mamíferos de Colombia.

Forest plantations are monocultures that have been increasing worldwide. These systems are less diverse compared to original forest, but they may contribute to the conservation of local biodiversity since these are used by many species, even some of conservation concern. The relative abundance and the true diversity were measured for volant and non-volant medium and large mammals in five tree plantations projects in the Andean and Caribbean regions of Colombia, and compared with native forest. 78 % and 71 % of the mammals present in the five localities were registered inside the coniferous and teak plantations, respectively. Threatened species such as Leopardus tigrinus and Saguinus Oedipus, were found in both types of tree plantations. The diversity profiles were similar between the native forest and tree plantations in almost all groups, only terrestrial mammals in coniferus plantations had significant differences. Differences in relative abundance between both forest and plantations were found for all mammal groups. We observed lower mammalian abundance in the tree plantations, which indicates that these modified ecosystems provide lower quality habitat for mammals, but there were far from being “green deserts”, on the contrary they were diverse systems. Species richness and the presence of threatened species are attributes that must be included in plantation management plans and in regional landscape designs.
