Monitoring of species' genetic diversity in Europe varies greatly and overlooks potential climate change impacts.
Genetic monitoring of populations currently attracts interest in the context of the Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected in biodiversity monitoring, and when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting of efforts to monitor population genetic diversity in Europe (genetic monitoring effort, GME), the evaluation of which can help guide future capacity building and collaboration towards areas most in need of expanded monitoring. Overlaying GME with areas where the ranges of selected species of conservation interest approach current and future climate niche limits helps identify whether GME coincides with anticipated climate change effects on biodiversity. Our analysis suggests that country area, financial resources and conservation policy influence GME, high values of which only partially match species' joint patterns of limits to suitable climatic conditions. Populations at trailing climatic niche margins probably hold genetic diversity that is important for adaptation to changing climate. Our results illuminate the need in Europe for expanded investment in genetic monitoring across climate gradients occupied by focal species, a need arguably greatest in southeastern European countries. This need could be met in part by expanding the European Union's Birds and Habitats Directives to fully address the conservation and monitoring of genetic diversity

The unique Mesola red deer of Italy: Taxonomic recognition (Cervus elaphus italicus nova ssp., Cervidae) would endorse conservation#
Most likely, the red deer Cervus elaphus Linnaeus, 1758 from the Bosco della Mesola Nature Reserve are the last autochthonous red deer in the Italian peninsula. In the 20th century, they nearly became extinct and have only recently recovered to higher numbers (at least c. 150 head in 2010). Apart from their historical relevance to the Italian fauna, they are also evolutionarily distinct at both the genetic and the morphological level. However, taxonomically, they are classified as part of the Central European red deer subspecies (Cervus elaphus hippelaphus), which encompasses most of the red deer from the European mainland. While we are fully aware of the high degree of arbitrariness of subspecific designations, it is also a fact that taxonomic recognition supports conservation, because subspecies are a legal category whereas other designations (such as evolutionarily significant units, ESUs) are not. We therefore argue that the Mesola red deer should be assigned to a subspecies of their own, and give an official description of Cervus elaphus italicus nova ssp., including the designation of a holo- and a paratype specimen. Given the evolutionary status of the Mesola red deer, subspecific recognition is certainly much better founded than is the case for many other so-called subspecies in present red deer taxonomy. © 2014 Unione Zoologica Italiana
Evolutionary history shapes the association between developmental instability and population‐level genetic variation in three‐spined sticklebacks
Microallopatry caused strong diversification in Buthus scorpions (Scorpiones: Buthidae) in the Atlas Mountains (NW Africa)
The immense biodiversity of the Atlas Mountains in North Africa might be the result of high rates of microallopatry caused by mountain barriers surpassing 4000 meters leading to patchy habitat distributions. We test the influence of geographic structures on the phylogenetic patterns among Buthus scorpions using mtDNA sequences. We sampled 91 individuals of the genus Buthus from 51 locations scattered around the Atlas Mountains (Antiatlas, High Atlas, Middle Atlas and Jebel Sahro). We sequenced 452 bp of the Cytochrome Oxidase I gene which proved to be highly variable within and among Buthus species. Our phylogenetic analysis yielded 12 distinct genetic groups one of which comprised three subgroups mostly in accordance with the orographic structure of the mountain systems. Main clades overlap with each other, while subclades are distributed parapatrically. Geographic structures likely acted as long-term barriers among populations causing restriction of gene flow and allowing for strong genetic differentiation. Thus, genetic structure and geographical distribution of genetic (sub)clusters follow the classical theory of allopatric differentiation where distinct groups evolve without range overlap until reproductive isolation and ecological differentiation has built up. Philopatry and low dispersal ability of Buthus scorpions are the likely causes for the observed strong genetic differentiation at this small geographic scale. © 2012 Habel et al
Towards a global list of accepted species II. Consequences of inadequate taxonomic list governance
Species lists are widely used in legislation and regulation to manage and conserve biodiversity. In this paper, we explore the issues caused by the lack of an adequately governed and universally accepted list of the world’s species. These include lack of quality control, duplicated effort, conflicts of interest, lack of currency, and confusion in the scientific use of taxonomic information. If species lists are to fulfill their role efficiently, then the governance systems underlying their creation must keep pace. Fortunately, modernization of species list governance is now possible as a result of advances in biodiversity informatics and two decades of experience working to create the backbone of a global species list

Towards a global list of accepted species III. Independence and stakeholder inclusion
A global consensus list of the world’s species must be based on the best available taxonomic research, and its contents should not be biased towards certain political or social aims. At the same time, users of any global list must be involved or consulted in its establishment to ensure that the list meets their needs. This paper argues that while these two desiderata— independence and inclusion—might seem to be in conflict, they are in fact compatible. More precisely, it suggests the roles taxonomists and users could play in establishing and maintaining a global consensus list to make sure that this list is both inclusive and independent
