A new species, Seseli salsugineum A.Duran & Lyskov (Apiaceae), is described from Lake Tuz Gölü area, Central Anatolia, Turkey. The new species is related to S. transcaucasicum and S. libanotis and differs in stem features (up to 200 cm tall and 5‒15 mm ⌀ vs. up to 80 cm tall and up to 6 mm ⌀ or up to 150 cm tall and 10‒20 mm ⌀), stem base pubescence (glabrous vs. densely pubescent or sometimes pubescent), leaf blades pubescence (glabrous with scabrid margin vs. entirely scabrid or glabrous), bracts 0.3‒0.8 mm wide, without membranous margin (vs. 1‒3 mm wide, with membranous margin), umbellules (tight, 5‒12 mm ⌀ vs. not tight 13‒15 mm ⌀ or 5‒6 mm ⌀), stylopodium depressed (not conical), mericarp ridges (finely ridged vs. distinctly ridged), fruit anatomy (vallecular vittae 3 vs. vallecular vittae solitary or 1‒2), habitat (salty marshes and salt steppes vs. grassy meadows, sparse forests, clearings in mountain forests, and subalpine meadows), and distributional range. In addition, S. salsugineum is recognized as a closely related to S. transcaucasicum and S. libanotis species by molecular analysis of nrITS/ETS.

This study is focused on the expansion of the distributional range of Lirata batesella (Westwood, 1874) (Hymenoptera, Eucharitidae) and based on a single female specimen deposited at Coleção Entomológica do Laboratório de Sistemática e Bioecologia de Predadores e Parasitoides of the Instituto Biológico, in Ribeirão Preto, São Paulo state, Brazil. Santarém, in Pará state, Brazil, the type locality, is the only known distribution record for the species. Here, we provide a new distribution record for L. batesella, in Luiz Antônio, São Paulo state, about 2,200 km south of the type locality, which represents a significant increase in its distribution range. A map showing the geographical distribution of L. batesella based on the new record and literature is provided.

AbstractWe report the capture of a single specimen of the species Paulia horrida Gray, 1840, off the coast of Arica, in the Arica and Parinacota Region, Northern Chile. This finding extends the currently known distributional range of the species by 2,434 km towards the south, since the southernmost known area for this species corresponds to Punta Sal, Peru. We discuss the importance of finding this relatively unknown species in Chile and the need to continue sampling to confirm the continuous distributional range of the species between the south of Peru and the north of Chile.

Pyrrosia sarthalensis, belonging to the family Polypodiaceae from the Bani Valley of Kathua district, Himalayan Jammu & Kashmir, India is described here as a new species. It shows restricted distributional range and so far, is only known from the Bani Valley, within the Himalayan centre of endemism. It is an epiphytic fern species having brownish sori, formed only on the upper half of the frond. Other diagnostic features include grooved rhizomes, rhizome scales, lamina size and structure, sori placement, size and structure, and spore characters. This new species is morphologically similar to P. flocculosa but differs in certain characters.

Fisheries are among the human activities that are most strongly affected by ongoing climate-related changes in the presence and abundance of fish species across the globe. The ecological and social repercussions of such changes for recreational fisheries are however still poorly understood. Here, we explore selected ecological and social dimensions of recreational angling and spearfishing targeting the bluefish (Pomatomus saltatrix) in Italy. The bluefish has undergone a northward expansion in the region over the last 20-30 years, during which it reached new areas and increased in abundance. Using digital videos and their associated data published by recreational fishers on YouTube we characterized ecological and social dimensions using a culturomics approach. Specifically, we focused on harvesting patterns, social engagement and sentiments related to the bluefish. Our study revealed four major results: (i) similar harvesting patterns (i.e., declared mass and seasonal upload patterns) related to videos by recreational anglers and spearfishers; (ii) higher social engagement (i.e., number of views and likes) for videos by recreational anglers than spearfishers; (iii) differences in themes of discussion, with anglers being mainly interested in fishing strategy and gears and spearfishers being more interested in fishing actions shown on the videos; iv) positive and negative sentiments of both recreational anglers and spearfishers towards the invasiveness and aggressiveness of the species. The latter represents an interesting trade-off associated with recreational fishing of the bluefish: it is perceived as an invasive species, but it is also a valued fish target because its voracity contributes to the quality of the recreational fishing experience. Our study showcases the value of exploring social media and associated data to better understand the ecological and human dimensions of marine recreational fisheries in relation to distributional range shifts of species associated with climate change.

Abstract Asian pit vipers belonging to the genus Craspedocephalus are a complex group of vipers, distributed in South and Southeast Asia. Their taxonomy is unresolved in many lineages across their distributional range. Here, we reassess the taxonomy and systematics of pit vipers of the genus Craspedocephalus in Peninsular India based on extensive field sampling, in particular in the Western Ghats. We build and expand on the previous findings of genetic relatedness between the peninsular Indian lineages with the Sundaic clade (C. puniceus complex) with greater evidence, based on additional taxa sequenced herein. We reconstruct the phylogeny of the group using three mitochondrial genes and delineated lineages using coalescent species delimitation methods. We then used multiple criteria including genetic divergence and separation in morphological and geographic space to designate taxonomic units. Our work revealed the presence of a South Asian radiation of the clade Craspedocephalus, with a few Sundaic members. Our study reveals the systematic relationships of four Peninsular Indian species of Craspedocephalus, including Peltopelor macrolepis and C. strigatus, sequenced here for the first time, that are classified or confirmed as members of Craspedocephalus. Hence, we place the genus Peltopelor in the synonymy of Craspedocephalus. Using our multi-criteria approach, we delimit four new cryptic evolutionary lineages within the Western Ghats escarpment of Peninsular India. These cryptic lineages belong to the C. malabaricus, C. gramineus and C. macrolepis complexes and are geographically and/or ecologically (in terms of habitat association) distinct from their sister lineages across their distributional range, while others are separated in morphological space. Our new phylogenetic tree and delimitation analysis thus reveals the presence of multiple clades with several cryptic lineages separated by geographical barriers or habitat association.

The invasive chestnut gall wasp (CGW), Dryocosmus kuriphilus, the worst pest of chestnut cultivation, has spread worryingly throughout Europe in less than 20 years. Despite the great concern around this pest, little is known about the status in its southernmost distribution in continental Europe. We assessed spatio-temporal patterns in the population dynamics, phenology and tree damage caused by CGW in southern Spain. Likewise, the relationship between these variables and thermal trends was evaluated. We found strong variation in the population dynamics and flight phenology among localities and over time, which were highly influenced by changes in thermal regimes. Specifically, warmer localities and vegetative periods promoted higher population densities, a partial increase in the survival of immature stages, and advanced flight activity. Moreover, tree damage evolved differently over time in each locality, which suggests that local conditions may determine differences in damage evolution. Our findings evidence that great spatio-temporal variability in the CGW populations takes place across invaded areas in its southernmost European distributional range. Although control mechanisms have been introduced, implementation of further control and management measures are critical to cope with this main threat for the chestnut industry and to prevent its spread to nearing chestnut-producing areas.
