Abstract The aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.

 RESUMEN Los mamíferos silvestres han sido estudiados en Michoacán desde el siglo XVIII por renombrados zoólogos y naturalistas. Sin embargo, todavía en 1949 se reconocía solo 85 especies, y hasta el año 2005 se proporcionó estimaciones completas basadas en integración de registros disponibles tanto nacionales como de colecciones científicas internacionales, ya que la información disponible para el estado se encontraba dispersa. Como resultado de proyectos recientes con nuevos registros, el objetivo de este análisis es proporcionar una cifra actualizada sobre la riqueza taxonómica de los mamíferos silvestres terrestres en el estado de Michoacán. Existen registros de 161 especies en 9 Ordenes, 25 familias, y 94 géneros que representan el 32% de las especies de México. El Orden con mayor número de especies es Chiroptera con 74 especies que representan el 53% de las especies del Orden en México. A pesar de la ubicación central de Michoacán en el país, y ser un estado muestreado por numerosos investigadores, todavía existe carencia de información para regiones remotas, y en algunos grupos de mamíferos. Por ejemplo, el jaguar, que a pesar de ser el mayor felino del país, se carecía de confirmación para el estado, afortunadamente durante 2010 se localizó una población en el estado. Otro aspecto limitante para la interpretación adecuada de la estimación actual, es la antigüedad de muchos registros, ya que los estudios más completos realizados a escala regional, como en la costa Michoacana son de hace 30 años, y durante ese periodo se ha incrementado la deforestación de selvas tropicales, por lo que desconocemos la situación actual que presentan las poblaciones de mamíferos en el estado. En Michoacán encuentran su límite más norteño en el Pacífico tres especies de amplia distribución en el Neotrópico, Tamandua mexicana,  Potos flavus y Sphiggurus mexicanus, por lo que deben limitarse áreas que protejan sus poblaciones. Palabras clave: Distribución, Mochoacán, mamíferos, especies.ABSTRACT The wild mammals in Michoacan state have been studied since the XVIII century by reknown zoologists and naturalists. However, still in 1949 only 85 mammals species were recognized, and until 2005 a complete estimate based on the integration of national and international data bases records available from Scientific collections, since all available information was scattered. As a result of recent surveys with new records, the aim of this analysis was to provide an updated statistic of the terrestrial wild mammals taxonomic richness in the Michoacan state. Available records correspond to 161 species in 9 Orders, 25 families and 94 genera which represent 32% of the Mexican mammal species. The Order with the major number of species is Chiroptera that includes 74 species thet represent 53% of the Order in Mexico. Despite its central location in the country, and considering that the state has been surveyed by several prestigious academics, there is still a lack of information for remote regions, and for some mammal groups. For example, the jaguar, even though constitute the largest wild felid in the country, no information was available for the state, fortunately during 2010 a population was localized in the state. Another limiting factor for the adequate interpretation of the current estimate is that many records are outdated, since the most complete studies performed at a regional scale, like in the Michoaca coast, are 30 years old, and during that time-frame, tropical forest loss increased dramatically, for instance, the current situation that present the mammal populations in the state are unknown. In Michoacan three species with a broad neotropical distribution present its northernmost limit on the Pacific, Tamandua mexicana, Potos flavus, and Sphiggurus mexicanus and there is the need to establish protected areas oriented to protect their populations. Key words: Distribution, Michoacan, mammals, species.

Importance of the Cerro de la Tortuga State Park for mammal conservation in the state of Morelos, Mexico The Cerro de la Tortuga State Park (PECT) in Mexico was declared a Protected Natural Area (ANP) in 2012. The technical report for the decree included a potential list of mammals in the area according to a bibliographic review of general distribution maps; their presence was not corroborated with field data. The aim of this study was to update the list of mammals present in the PECT with field work data so as to clarify the value of the natural resources that this ANP protects, and thus contribute to the knowledge, management and conservation of mammals in the region. Field work took place from February to October 2017. We sampled six sites over two different periods, first, during the dry season and second, during the rainy season. Direct and indirect survey methods were used to sample mammal presence. Thirty species of wild mammals were recorded within the PECT, representing 28 % of the mammal species reported for the state of Morelos. The species recorded belong to 27 genera, 16 families and six orders. Chiroptera was the richest order, with 14 species (47 %), followed by Carnivora with 7 species (23 %), Rodentia with five (17 %), Didelphimorphia with two (7 %), and Lagomorpha and Xenartra with one species (3 %) each. Among all the species detected, only Leptonycteris yerbabuenae is classified as threatened in the NOM-059-2010 and as nearly threatened in the IUCN red list. As the PECT could operate as a key landscape corridor between other ANPs in the state for several mammalian species, its conservation and optimal management is important to adequately protect the regional natural resources.

AbstractHerbivorous mammals are important for natural ecosystems even today, but how much stronger would there effects be without human-linked extinctions and extirpations? The ranges of many mammal species have contracted and numerous species have gone extinct due to human pressures, so herbivore impacts in even seemingly natural ecosystems likely deviate from their pre-anthropogenic state. However, such effects remain poorly understood and often unrecognized. To address this issue, we here quantified and mapped plant consumption by all terrestrial mammals in natural areas based on both current and estimated natural ranges. We then compared the estimated consumption rates to current plant net primary productivity, and summarised the results for global ecosystem types both broadly and in the wildest remaining natural areas around the world (the Last of the Wild). We found that wild mammals consume 7.3% (95% interquantile range: 0.85% - 26%) of net primary productivity in current natural areas, and that this would be much higher in the absence of extinctions and extirpations, namely 13% (95% interquantile range: 1.7% - 40%), i.e., a >50% higher consumption rate. Marked human-linked declines in herbivory were seen even in the wildest remaining natural areas, where mammals now consume a mean of 9% (95% interquantile range: 2.2% - 26%) of plant primary productivity, which is only 60% of no-extinction level. Our results show that mammalian herbivores naturally play an important part in ecosystems at a global scale, but that this effect has been strongly reduced by extinctions and extirpations.

The article studies documents from the State Archive of the Orel Region (GAOO) as an important source for studying the sense of justice of the Oryol gubernia peasants in early 20th century. Introduction of new archival materials allows to flesh out our knowledge and to produce a true-to-life picture of the Oryol peasants’ way of life. The peasant origins of the majority of the population necessitate a comprehensive study of peasant legal consciousness. Historical legacy is pertinent to present day, and forgetting its lessons is fraught with consequences. Evolution of modern Russian statehood hedges on its historical and legal traditions. The article studies documents in the fonds of public authorities, police, gendarmerie, courts, and prosecution offices. Introduction of new materials of public authorities, police, gendarmerie, courts, and prosecution offices into the scholarship promotes the analysis of the evolution of peasant legal sense in early 20th century. The chronological framework of the article is limited to the period from 1900 to 1917, its territorial framework is limited to the Oryol gubernia in its pre-revolutionary borders. The article studies reports, dispatches, and circular letters using the comparative method. The intensification of peasant protest was incidental to the first Russian revolution of 1905-1907 – the peasants hoped to force the government to settle the agrarian question, wherein lay the crux of their interests. As peasants of the Oryol gubernia suffered from shortage of arable land, antimonarchical sentiments gained momentum and translated a growing number of trials for contempt of the Emperor. Illegal literature spreading among the peasants, further radicalized them, and the authorities grew more and more hesitant in their assessment of peasant loyalty, which is quite intelligible in the archival documents. Thus, the use of new archival documents in addition to published materials promotes the scholarship on the peasant legal sense.

Beriberi is caused by thiamine deficiency. Early 20th century epidemics in Japan were attributed to rice contaminated by citreoviridin mycotoxin. Our investigation of an outbreak of beriberi in Brazil showed an association of beriberi with the consumption of poor quality subsistence farming rice, although, unlike other investigators of this outbreak, we did not identify citreoviridin producing fungi in the implicated rice.

The distribution and abundance of small terrestrial mammals were assessed in forest adjacent to powerline easements at three different sites in New South Wales. At each site, four transects of 300 m length extended into the forest from the edge of the easement. The abundances of two native species (Antechinus stuartii, Rattus fuscipes) did not differ significantly with distance from the easement but abundances differed markedly among sites. Mammals were captured in only one easement where dense vegetation was present. Feral carnivores, which may mediate edge effects on small mammals, were surveyed by using hair-sampling tubes. Cats and dogs were detected only 50–200 m inside the forest. Foxes were not detected by hair-tubes but were observed on two easements. These results suggest that powerline easements may not create edge effects in eucalypt forest for some native mammal species, although further studies are needed to determine the generality of this conclusion. We recommend that easement management should be more benign to native mammals, given the ubiquity of this form of habitat fragmentation. Promotion of dense vegetative cover and habitat linkages within easements could achieve this.

Based on species occurrence records of museum collections, published literature, and unpublished records shared by mammalian experts, we compiled a distribution database for 59 terrestrial mammals populating the extensively protected Dobrogea Region of Romania. The spatial patterns of mammal distribution and diversity was evaluated and systematic conservation planning applied to identify priority areas for their conservation. The spatial analyses revealed that intensive sampling was not directly correlated to mammal diversity but rather to accessibility for inventory. The spatial prioritisation analysis indicated a relatively aggregated pattern of areas with a high or low conservation value with virtually no connecting corridors between them. The significant overlap between Natura 2000 sites and national protected areas induced an over-optimistic vision of the effectiveness and representativeness of existing Natura 2000 network for species found in Annexes II and IV of the Habitats Directive. These results represent a key step in identifying core areas for the protection of mammal diversity and dispersal corridors for improved connectivity, and to guide future conservation efforts in increasing the effectiveness of the existing protected areas in the context of environmental changes.
