Conservation Decisions

The current state of knowledge of freshwater decapod crustacean diversity of the Guayana Shield Region is briefly assessed, based upon information gathered from the scientific literature as well as unpublished data from academic theses, technical reports, and carcinological collections. The decapod fauna of the region is presently known to include 64 species and subspecies within six families and 17 genera. Diversity by countries, basins, and rivers is listed, comments on endemic, rare or threatened species are made, and information about relevant taxonomic literature is presented. Seven priority areas for conservation actions concerning crustacean decapods are suggested and related to the 25 priority areas defined by the Fishes and Freshwater Working Group at the Guayana Shield Conservation Priority Setting Workshop, held at Paramaribo (Suriname) in April 2002.

AbstractAlthough trees are key to ecosystem functioning, many forests and tree species across the globe face strong threats. Preserving areas of high biodiversity is a core priority for conservation; however, different dimensions of biodiversity and varied conservation targets make it difficult to respond effectively to this challenge. Here, we (i) identify priority areas for global tree conservation using comprehensive coverage of tree diversity based on taxonomy, phylogeny, and functional traits; and (ii) compare these findings to existing protected areas and global biodiversity conservation frameworks. We find that ca. 51% of the top-priority areas for tree biodiversity are located in current protected areas. The remaining half top-priority areas are subject to moderate to high human pressures, indicating conservation actions are needed to mitigate these human impacts. Our findings emphasize the effectiveness of using tree conservation priority areas for future global conservation planning.

This research presents a literature review of published scientific literature on the Coromandel Peninsula, a well-known region of the northern part of the North Island of New Zealand. It contains many biological, geological, and historical features and is well known for beautiful scenery, resulting from a volcanic rock-dominated terrestrial environment influenced by oceanic factors at the coast. All these factors have combined to make the Coromandel a popular tourism destination for New Zealanders and offshore visitors. In researching the current state of knowledge of the region, we searched three scientific databases to define the main ways of studying the region. The results demonstrated a high interest in biological and environmental factors, reflected in the type and scale of conservation measures applied to flora and fauna of the region. Additionally, specificity of geological evolution was a highly examined subject, in the context of hydrothermal alteration as related to gold and silver mineralization resulting in extensive exploration and mining. Meanwhile, indigenous cultural aspects of the land were not recognizable as expected within Western scientific literature, even though the region contains sites recognized as some of the earliest Māori habitations. Therefore, we suggest future studies to expand our understanding of scientific, cultural, and social aspects of the region as applied to the field of conservation in the region.

The article is devoted to the analysis of some features of the investigation of football hooliganism. The current state and trends of football hooliganism are considered (including during the COVID-19 pandemic). The main problems faced by the investigation authorities during the detection and investigation of football hooliganism have been identified. In the process of working on the article, the scientific literature on informal youth groups, the fight against extremism, the investigation of group crimes of football fans was analyzed. The purpose of the study is to identify and study the features of the investigation of hooliganism committed by football fans. The object of research is the peculiarities of the investigation of hooliganism committed by football fans. During the writing of the article, the following methods were used: observation, analysis, synthesis, comparison, generalization, extrapolation, modeling, and information approach. As a result of the conducted research, the modern tendencies of football hooliganism are defined. Emphasis is placed on the peculiarities of the transformation of football fans. The principal problems of detection and investigation of football hooliganism are outlined, recommendations for prevention and counteraction to crimes committed by football fans are developed.

‘Key biodiversity areas' are defined as sites contributing significantly to the global persistence of biodiversity. The identification of these sites builds from existing approaches based on measures of species and ecosystem diversity and process. Here, we therefore build from the work of Sgró et al. (2011 Evol. Appl. 4 , 326–337. ( doi:10.1111/j.1752-4571.2010.00157.x )) to extend a framework for how components of genetic diversity might be considered in the identification of key biodiversity areas. We make three recommendations to inform the ongoing process of consolidating a key biodiversity areas standard: (i) thresholds for the threatened species criterion currently consider a site's share of a threatened species' population; expand these to include the proportion of the species' genetic diversity unique to a site; (ii) expand criterion for ‘threatened species' to consider ‘threatened taxa’ and (iii) expand the centre of endemism criterion to identify as key biodiversity areas those sites holding a threshold proportion of the compositional or phylogenetic diversity of species (within a taxonomic group) whose restricted ranges collectively define a centre of endemism. We also recommend consideration of occurrence of EDGE species (i.e. threatened phylogenetic diversity) in key biodiversity areas to prioritize species-specific conservation actions among sites.

Snake Fungal Disease

Since 2006, there has been a marked increase in the number of reports of severe and often fatal fungal skin infections in wild snakes in the eastern USA. The emerging condition, referred to as snake fungal disease (SFD), was initially documented in rattlesnakes, where the infections were believed to pose a risk to the viability of affected populations. The disease is caused by Ophidiomyces ophiodiicola , a fungus recently split from a complex of fungi long referred to as the Chrysosporium anamorph of Nannizziopsis vriesii (CANV). Here we review the current state of knowledge about O. ophiodiicola and SFD. In addition, we provide original findings which demonstrate that O. ophiodiicola is widely distributed in eastern North America, has a broad host range, is the predominant cause of fungal skin infections in wild snakes and often causes mild infections in snakes emerging from hibernation. This new information, together with what is already available in the scientific literature, advances our knowledge of the cause, pathogenesis and ecology of SFD. However, additional research is necessary to elucidate the factors driving the emergence of this disease and develop strategies to mitigate its impacts. This article is part of the themed issue ‘Tackling emerging fungal threats to animal health, food security and ecosystem resilience’.
