The study of the distribution of species is increasingly more necessary to understand the extinction of mega mammals that occurred during the late Pleistocene and early Holocene periods. Spatial analysis procedures, such as cartographic modelling and multicriteria evaluation techniques, allow for the finding of spatial correspondences between geographic, environmental, faunal and human variables, to investigate the causes of these losses. From a conceptual approach, this paper analyses the characteristics of the interdisciplinary approach between Geography and Palaeontology, the role of spatial models in scientific realism, rationalist causality processes, and the possibilities of quantitative techniques in systemic spatial analysis, taking the case of the ground sloth Scelidotherium leptocephalum (Mylodontidae, Xenarthra). It concludes with a proposal for cartographic modelling as a logical construction of application in which the spatial dimension takes a central place of inquiry. [ABSTRACT FROM AUTHOR]

Introduction: Coffee is a highly mycotrophic plant, its interaction with arbuscular mycorrhizal fungi has been studied among different tropical countries. The majority of the published works indicates that coffee is benefited from the mycorrhizal association, where the AMF confers protection against pathogens and diseases, increases water absorption, as well as it increases the adaptation of the plant at transplant from nurseries to the main plantation. Objective: A review was made where we summarized and analyze the research reports of AMF with coffee from at least the past 10 years, focused on AMF global species distribution, nutritional benefits of the association and interaction with pathogens. Methods: We retrieved available bibliographic data from coffee producer countries in public databases. We considered published works from 2000 to 2019, nevertheless, we included classic papers on the topic, outside that period, mainly the ones performed in Brazil since 1986. We organized the number of reported species per country, we look for synonyms, grouped them by family, genera and species. The reports that only reported genera or where ambiguous were used as reference but not considered for the final analysis. We summarized the reports of the benefits of the AMF interaction in coffee, as well as pathogen tolerance. Results: The collected data shows that there are more than 100 AMF species associated with coffee, which represents more than a third part of the total of reported species worldwide. We found that Colombia has the highest richness, but it also has the highest number of published reports. Conclusions: This information shows the benefits of the incorporation of AMF to coffee plantation programs, because these fungi are a key element in coffee plant nutrition, nevertheless, the coffee variety should be considered when introducing AMF, as not all associations has been efficient.

Anopheles (Nyssorhynchus) darlingi has been reported since 1931 in border areas of the department of Loreto, mainly along the borders with Brazil and Colombia. In 1994, during an outbreak of malaria, An. darlingi was found in neighboring towns to Iquitos. At present, its distribution has expanded considerably in Loreto. This paper reviews literature available for all possible information on the distribution of mosquitoes, particularly anopheline in the Amazon region of the country, with special emphasis on An darlingi. Entomological collections were also conducted in the departments of Madre de Dios and Ucayali in order to know and verify the distribution of An. darlingi. At present, the distribution of the species is confined to localities in southeastern Peru with Bolivia border towns, in a town near the Abujao River in the department of Ucayali, and widely in the northeastern region of the Amazon basin of Loreto in Peru.

This paper discusses the role played by Petalostelma robertii (S. Moore) Liede & Meve (Apocynaceae) in the ethnobotany of two ethnic groups from the Argentine semi-arid Chaco: the Wichí and the Toba-Pilagá peoples, who use it as a love spell. It provides data on the morphology, ecology and geographical distribution of the plant, as well as references on its significance in the social and spiritual lives of these ethnic groups. Its presence in Argentina is mentioned for the first time, and the morphological similarities and discrepancies in the collections made in different localities in the region are discussed. The provisional nature of the identity given to the plant is categorically stated. Its ethnobotanical interest and the need to assign a scientific name to the plant, at least an approximate one, are discussed. On the taxonomic and floral levels, the conclusion is that a detailed study of the exsiccata available is required in order to clarify the identity of a group of plants related to P. robertii.

This paper examines the use of different microhabitats throughout the day, year, by sex, by age, at different intervals of altitude and its implications for thermoregulation and conservation. Overall 49.5% of the lizards used trees, 32.62% rocks and less often 2.3% shrubs (X2 = 216.06, gl 3, p < 0.05). The analysis of microhabitat used by sex revealed significant differences among young, female, and male (X2 = 7.24, gl 6, p < 0.05). The young females most often used rocks, while subadults and adults preferred to use trees (X2 = 13.38, gl 6, p < 0.05). In males, subadults and young used rocks, and adults trees (X2 = 15.22, gl 4, p < 0.05).The altitudinal distribution has an effect on habitat use; in the altitudinal range of 800 to 1,100 m these lizards have a tendency to be more arboreal, and between 1,100 and 1,400 m more frequently used rocks (X2 = 36.21, gl 6, p < 0.05). In the dry season there was a significant difference in the use of microhabitats between 9:00 and 14:00 hours, with the highest number of sightings on trees and rocks. In the rainy season there was no significant difference in the analysis of microhabitat use over the hours of the day. The average body temperature was 33.52 °C (22.0-39.0 ± 2.9). There were no significant differences in body temperature of lizards in different microhabitats. Cloacal temperatures in all microhabitats were 2 °C and 3 °C higher than air temperatures and substrate. Most sightings were between 10:00 and 15:00 hours so this species is considered a diurnal lizard showing thigmothermy and heliothermy. There were significant differences (F1,414 = 5.0918, p = 0.024561) in the lizard cloacal temperatures between the rainy (33.2 °C ± 3.17, n = 215) and dry seasons (34.2 °C ± 5.4, n = 201). Trees are important for thermoregulation in this species; however, even though these lizards could live in deforested areas, they might encounter thermoregulatory difficulties due to reduced periods of activity.

In this paper the revision of the series Leiocarpae Urb. is presented, and Turnera callosa Urb. is chosen as lectotype. This series has a distribution similar to that of the genus Turnera in America, most species living in the Chaquean biogeographical region. It has 55 species, the following taxa being new: T. angelicae, T. dasytricha var. crinita, T. diamantinae, T. emendata, T. fissifolia, T. glabrata, T. gouveiana, T. humilis, T. iterata, T. jobertii, T. luetzelburgii var. dubia, T. melochioides var. rugosa, T. paradoxa, T. patens, T. rosulata, T. vallsii, T. venezuelana and T. vicaria. Two new series are also proposed, Conciliatae Arbo for T. rubrobracteata Arbo, a species with an unusual combination of characters, which does not fit in any other series, and Sessilifoliae Arbo, including T. dichotoma and T. revoluta which were excluded from Series Capitatae; the comparative analysis with the members of Leiocarpae has demonstrated that they neither belong to the last series. Keys to identify the different series of the genus and keys for the species of each series treated are provided, as well as morphological descriptions, illustrations and distribution maps.

The objectives of this paper were to present a taxonomic list and determine the richness and local distribution of the species of the phylum Echinodermata at Bahia de La Paz. An exhaustive review of published material on this subject from the last century to 1995 was made, and complemented with an analysis of specimens collected in the zone and included in the UNAM and UABCS collections. After the taxonomic information was analyzed and validated, it was found that, at Bahia de La Paz, 92 echinoderm species have been recorded: 21 species of the class Asteroidea, 18 of the class Ophiuroidea, 26 of the class Echinoidea and 27 of the class Holothuroidea. This level of echinoderm species richness is one of the highest known for the Pacific coast of Mexico and the tropical eastern Pacific region; 41% of the species have been found only in one zone of the bay and just 7% inhabit the whole site. The high level of species richness of Bahia de La Paz might be explained as a combination of a large sampling effort in the zone, together with the incidental occurrence of several species, the locationof the bay (near a zoogeographical transition zone) and the variety of local habitats.
