Present study reports the habitat preference and spatiotemporal variations in the population abundance of limpets Cellana karachiensis and Siphonaria siphonaria inhabiting rocky intertidal zones of Veraval coast, Kathiawar Peninsula, India. The entire intertidal zone of the Veraval coast was divided into five microsampling sites based on their substratum type and assemblage structure. Extensive field surveys were conducted every month in these microsampling sites and the population abundance of two limpet species was analyzed using belt transect method. The results revealed that C. karachiensis was the dominating species at microsampling Site-1 (having rocky substratum) possibly due to its ability to tolerate high desiccation, salinity, and temperature fluctuations, while the S. siphonaria was found to be the most dominating species at microsampling Site-2 (having rocky substratum with abundant algal population) possibly due to their preference for the perpetual wet areas. The study also indicated that S. siphonaria preferred upper littoral zone where the green algae were abundant while C. karachiensis preferred the spray zone, where it faces almost no competition for space and food with other molluscs. The condition of the spray zone is very harsh for other species to survive.

The long-tailed goral (Naemorhedus caudatus) is a critically endangered herbivore in South Korea. Despite government efforts to recover the population through reintroduction programs, the animal remains vulnerable to heavy snowfall. From March to June 2010, 24 animals were found dead due to heavy snowfall in the Wangpi Stream basin. In this study, we hypothesized that gorals that died due to snowfall are low-status individuals that lived in the sub-optimal or non-suitable areas. Using the occurrence data from extensive field surveys from 2008 to 2010 in the Wangpi Stream and the carcass location data, we (1) defined the goral habitat characteristics and (2) compared the habitat characteristics between dead and living gorals using ensemble species distribution modeling. The results suggested that the sites where dead gorals were found were highly related to typical goral habitats. These results implied that the optimal goral habitats could become uninhabitable following heavy snowfall. Most of the dead animals were pregnant females or were young, implying that they could not escape their primary habitats due to lower mobility. Thus, when there is a climate catastrophe, the optimal goral habitats should be considered for rescue and artificial feeding.

The shanny/common blenny (Lipophrys pholis) and long-spined scorpionfish/bullhead (Taurulus bubalis) are commonly encountered, sympatric species within much of Great Britain's rocky intertidal zones. Despite being prey items of the cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) respectively, and both contributors to the diet of the near-threatened European otter (Lutra lutra), little is known on the population dynamics of the temperate specimens of Great Britain. It is further less known of the degrees of sympatricity between the two fish species and to what extent they are able to coexist. The current study examines spatio-temporal distributions and abundances at various resolutions: monthly population dynamics of both species along England's Yorkshire coast and seasonal population dynamics along the Yorkshire coast and around the Isle of Anglesey, Wales. Studies of their abundances, sizes, degrees of rock pool co-occurrence and diel activities are further examined, which indicate coexistence is maintained when interspecific co-occurrence takes place only between specimens of similar sizes, thus demoting size-related dominance hierarchies.

Extensive field surveys of the Critically Endangered Central and Eastern Rûens Shale Renosterveld have uncovered that Notobubon striatum, as currently circumscribed, comprises two distinct species. Upon careful examination of the type material it has become clear that names exist for both species. The type specimen of N. striatum clearly matches the lesser known species, a large shrub, ca. 1 m. tall, with a powerful anise-scent and which is restricted to the banks of seasonal rivers and watercourses in the Central and Eastern Rûens Shale Renosterveld. The second and better known entity, with a wider distribution, corresponds to the type material of Dregea collina Ecklon & Zeyher. As such, a new combination, Notobubon collinum (Ecklon & Zeyher) Magee, is here made to accommodate this taxon, restricted to dry quartz and silcrete patches or outcrops in Eastern Rûens Shale Renosterveld. In their revised circumscriptions N. striatum and N. collinum are readily distinguished by habit, scent, leaf size and division, as well as leaf lobe shape and sepal size. Comprehensive descriptions of both species are provided, together with notes on their ecology and conservation status, and the existing key to the species of Notobubon updated. This brings the number of recognised species in the genus to thirteen.

AbstractA chemotaxonomic study was carried out on the Lethariella cladonioides complex, including L. sernanderi and L. cashmeriana of the subgenus Chlorea, based on extensive field surveys and a detailed morphological and chemical analysis. Only one species, L. cladonioides made up of five chemical races, is recognized. Lethariella sernanderi and L. cashmeriana are reduced to synonyms under L. cladonioides. The presence of a remarkable chemical polymorphism within the population of L. cladonioides is demonstrated. New data on the chemistry and the distribution of the species are presented.

The aim of current study is to provide a significant traditional knowledge on wild medicines used for ethnoveterinary purposes in the rural area of Maraog region in district Shimla. The medicinal plants have played a significant role in the treatment of human as well as animal’s diseases. The rural people of the Maraog region were interviewed through a questionnaire and extensive field surveys were conducted from June 2020 to July 2021. The discussion, observations and interviews were conducted in study site and included 96 informants. The information gathered from the residents is presented in a table format and includes scientific and local names, different parts used, diseases treated and mode administration. The most commonly used taxa are calculated with used value. The study revealed 100 plants in which trees (7), shrubs (26), herbs (56), ferns (5), grasses (3) and climbers (3) were identified. The most commonly documented livestock diseases were found to be hoof infections, eyes infections, poisoning and skin infections. In the current study, the Rosaceae family was reported as being the highest number (11), followed by Asteraceae (10) and then Lamiaceae (6). It was found that leaves, roots, flowers and fruits are the commonly used parts for ethnoveterinary medications. The phytochemicals present in the plant, such as alkaloids, sterols, glycosides, flavonoids, lignin, coumarins and terpenoids, etc., may be responsible for their medicinal properties. In this documentation, it was observed that the younger generation does not have good knowledge of medicinal plants as compared to the older ones. Therefore, it is necessary to preserve the traditional knowledge of these medicinal plants before their permanent loss. The documentation and conservation of medicinal plants can be a good start for novel phytopharmacological research in the veterinary field.
