The diversity and richness of the Brazilian flora are documented in herbarium collections. When areas are deforested, but not documented, we lose both flora and the opportunity to know which species occupied those areas. The south-eastern mesoregion of Mato Grosso State, comprising 22 municipalities, has undergone the loss of native vegetation cover, accelerated by the substantial expansion of agribusiness. For an in-depth look at the consequences and the current state of the flora in that mesoregion, we consulted both speciesLink and JABOT databases. More specifically, we carried out a comprehensive study of herbarium collections by municipality and compiled data including scientific name, collection date, collection locality, collector name and observations made during collection. We obtained 5,861 records of angiosperms, ferns and lycophytes of 160 families, 770 genera and 1,792 species. The specimens are deposited in 80 herbaria of which the Herbarium of Universidade Federal de Mato Grosso (UFMT) hosts the largest collection. Rondonópolis was the most sampled municipality, whereas 50% of the municipalities were poorly sampled and one showed no collection records at all. Amongst the species occurring only in Mato Grosso, eleven were collected only in that mesoregion and twenty species were under some degree of threat. Our study recommends increasing collection and identification efforts to enable effective conservation actions and improve richness estimates for the State of Mato Grosso and the Cerrado, in general, before more of the flora is lost to deforestation.

Abstract This research consists of the taxonomic-floristic treatment of taxa of Mimosoideae occurring in the Brazilian Chaco. The specimens analyzed were collected from 2004 to 2012 in Chaco remnants located in southwestern Mato Grosso do Sul, Brazil. Mimosoideae is represented by 39 taxa belonging to 14 genera; among the most representative, Mimosa (16 taxa) and Prosopis (4 taxa) are highlighted. Chloroleucon chacoense, Mimosa centurionis and Prosopis alba are new records for the Brazilian Flora. Prosopis nigra has its occurrence expanded. Mimosoideae is the second subfamily in species richness compared with other subfamilies of Leguminosae studied in the Brazilian Chaco. This work includes morphological descriptions, identification keys, illustrations and taxonomic comments.

Multiple languages being spoken within a species distribution can impede communication among conservation stakeholders, the compilation of scientific information, and the development of effective conservation actions. Here, we investigate the number of official languages spoken within the distributions of 10,863 bird species to identify which ones might be particularly affected by consequences of language barriers. We show that 1587 species have 10 languages or more spoken within their distributions. Threatened, migratory and wide-ranging species have especially many languages spoken within their distribution. Particularly high numbers of species with many languages within their distribution are found in Eastern Europe, Russia and central and western Asia. Global conservation efforts would benefit from implementing guidelines to overcome language barriers, especially in regions with high species and language diversity.

The current state of the national economy means that businesses need to constantly look for ways to improve their efficiency and find new ideas to address their shortcomings. The problem of improving the financial condition of the enterprise and finding ways to improve the financial condition of the enterprise is primarily related to the mechanism for assessing the financial condition of the enterprise. The study of the financial condition of the enterprise gives an advantage to the business entity among competitors, allows to identify shortcomings in the activities of the enterprise and to form methods to improve its activities. Both internal and external factors have a significant impact on the financial condition of the enterprise. Since the internal and external environment is constantly changing, so business is characterized by uncertainty. The article considers the specifics of the analysis of the financial condition and prospects of economic development of the outsourcing company. The author generalizes the concept of "financial condition of the enterprise" and substantiates the importance of a comprehensive study of its evaluation indicators. Based on the analysis of the financial condition of Corplex LLC identified promising ways of economic development of the studied outsourcing company.

SummaryKnowledge of ecological patterns and processes is key to effective conservation of biodiversity hotspots under threat. Renosterveld is one of the most critically endangered habitats in the biologically unique Cape Floristic Region, South Africa. For the first time, we map and synthesize the current state of knowledge on renosterveld ecology and conservation. We investigated 132 studies for the themes, locations and taxa of renosterveld research and the fragmentation, threats, recommendations and barriers to renosterveld conservation. More studies focused on plants than any other taxa (48% of articles) and are conducted mostly in larger, intact renosterveld fragments. The most commonly identified threat to renosterveld was agricultural intensification; conservation recommendations spanned improved farming practices, formal protection and local patch management. Conservation implementation has been piecemeal and has depended largely on the goodwill of landowners, which can be constrained by costs of conservation measures and a lack of suitable restoration means. Citizen science is a promising potential solution to some barriers. Fragmented knowledge in such a transformed and relatively densely populated region highlights the scale of knowledge gaps for other biodiversity hotspots and has implications for ongoing conservation work.

Legally recognized Indian reserves of Brazilian Amazonia span over 100 million ha of largely intact forest and are potentially valuable for biodiversity conservation. An important example is provided by the Kayapó territories which span more than 13 million ha in Pará and Mato Grosso, Brazil, and protect a unique and vulnerable Amazonian forest type that is poorly represented in existing nature reserves. The Kayapó of southern Pará have stopped invasion of their lands by the most perverse threats to Amazonian forests, but they have become involved extensively in the sale of illegal logging concessions for the high-value timber species mahogany (Swietenia macrophylla). In 1992, the non-governmental organization Conservation International do Brasil (CI-Brasil) began a conservation and development project with the Kayapó community of A’Ukre with the objective of providing economic alternatives to logging and protecting a population of mahogany trees. This paper demonstrates the conservation benefits that can be achieved by supporting sustainable development of indigenous peoples in the Amazon. Specifically, we: (1) evaluate the ecological importance of the Kayapó reserves from a biodiversity conservation viewpoint, (2) evaluate the conservation success of the CI-Brasil project and test whether the implementation of the conservation alliance between A’Ukre and CI-Brasil satisfies common pool resource principles, and (3) propose a model for expanding the small-scale conservation results achieved by the CI-Brasil project to all Kayapó territories. Several mammals (Tayassu pecari, Pteronura brasiliensis, Priodontes maximus, Panthera onca) and at least one bird species (Anodorhynchus hyacinthinus) listed as endangered were regularly encountered within 15 km of A’Ukre. Taxa encountered at relatively high densities in the project area included large cracids, lowland tapir, and white-lipped peccary, indicating an ecosystem that is not severely impacted by hunting. Harvest offtakes of mahogany averaged 0.44 stems ha−1 within groves and 0.13 stems ha−1 at the landscape level. We estimate that 85% of the fruiting population of Swietenia macrophylla has been removed in harvested Kayapó territories in Pará. We found Kayapó social organization in A’Ukre to meet criteria of successful common pool resource institutions. The CI-Brasil project resulted in protection of an intact mahogany population in 8000 ha of forest maintained by the community for ecological research purposes and mahogany preservation. Our analysis attributes the success of the conservation alliance with A’Ukre to: (1) direct benefits accruing to all members of the community, (2) fulfilment of criteria for development of common pool resource institutions, and (3) long-term commitment of an external agency. We propose that by implementing these three elements elsewhere, the modest conservation result achieved at A’Ukre could be expanded to include the entire Kayapó nation and thereby contribute to conservation of more than 13 000 000 ha of forest and cerrado in the south-eastern Amazon.

As human pressures on the environment continue to spread and intensify, effective conservation interventions are direly needed to prevent threats, reduce conflicts, and recover populations and landscapes in a liaison between science and conservation. It is practically important to discriminate between true and false (or misperceived) effectiveness of interventions as false perceptions may shape a wrong conservation agenda and lead to inappropriate decisions and management actions. This study used the false positive risk (FPR) to estimate the rates of misperceived effectiveness of electric fences (overstated if reported as effective but actually ineffective based on FPR; understated otherwise), explain their causes and propose recommendations on how to improve the representation of true effectiveness. Electric fences are widely applied to reduce damage to fenced assets, such as livestock and beehives, or increase survival of fenced populations. The analysis of 109 cases from 50 publications has shown that the effectiveness of electric fences was overstated in at least one-third of cases, from 31.8% at FPR = 0.2 (20% risk) to 51.1% at FPR = 0.05 (5% risk, true effectiveness). In contrast, understatement reduced from 23.8% to 9.5% at these thresholds of FPR. This means that truly effective applications of electric fences were only 48.9% of all cases reported as effective, but truly ineffective cases were 90.5%, implying that the effectiveness of electric fences was heavily overstated. The main reasons of this bias were the lack of statistical testing or improper reporting of test results (63.3% of cases) and interpretation of marginally significant results (p < 0.05, p < 0.1 and p around 0.05) as indicators of effectiveness (10.1%). In conclusion, FPR is an important tool for estimating true effectiveness of conservation interventions and its application is highly recommended to disentangle true and false effectiveness for planning appropriate conservation actions. Researchers are encouraged to calculate FPR, publish its constituent statistics (especially treatment and control sample sizes) and explicitly provide test results with p values. It is suggested to call the effectiveness “true” if FPR < 0.05, “suggestive” if 0.05 ≤ FPR < 0.2 and “false” if FPR ≥ 0.2.

We report the occurrence of several remnant stands of Trithrinax schizophylla Drude in Porto Murtinho municipality, southwestern Mato Grosso do Sul state, Brazil. Until recently, the species was considered as probably extinct in the country. Trithrinax schizophylla is found only in the Chaco provinces of Argentina, Paraguay, and Bolivia, with a narrow strip in the southwestern region of Mato Grosso do Sul. The region is one of the most modified inside the Pantanal wetland in Brazil, and conservation actions are in need to protect this and other species in the region.
