Hard ticks are blood-sucking ectoparasites infesting all types of domestic ruminants throughout the world and serve as vectors in the dissemination of a wide variety of pathogens. Sheep and goat farming is a vital economic source for resource-poor farming communities in the Khyber Pakhtunkhwa (KPK) province of Pakistan. Aim: The aim of present study is to study the epidemiological profile of ticks in various agro-climatic zones of KPK. Materials and Methods: A total of 1500 (882 sheep and 618 goats) of all age groups and sexes were examined for the presence of ticks belonging to six districts in four agro-climatic zones of KPK province, Pakistan. Non-probability sampling was undertaken based on animal hosts’ selection, collection of hard ticks, and epidemiological parameters. Ticks collected from sheep and goats were identified phenotypically using standard keys. Results: The results revealed that Rhipicephalus microplus (36.2%) was the predominant tick species followed by Hyalomma anatolicum (25.2%), Hyalomma trancatum (18.1%), Hyalomma aegyptium (11.3%), Hyalomma asiaticum (6.9%), and Haemephysalis bispinosa (2.4%). Different epidemiological parameters showed that weather, humidity, and host age negatively affect (p < 0.05) tick load while temperatures (Minimum and Maximum), sunshine (hrs), and precipitation positively affected (p < 0.05) tick load. Host sex only showed a positive association with tick load (p > 0.05). The highest value of tick diversity index (H) 0.36748 was noted for Hyalomma anatolicum as this tick species was commonly distributed in three agro-climatic zones except in the Suleiman Piedmont zone, while Haemaphysalis bispinosa has the lowest diversity index (0.0334) as it was only found in the Central Valley Plains zone of KPK. The Shannon diversity index of tick diversity was highest at Barikot while the lowest index value was at Kabal (2.407). Similarly, a higher Simpson’s diversity index was at Barikot (0.9554) and the lowest hard index was noted at Takht bai (2.874). The dominance index showed that the tick species were more dominant at Takht bai (0.1251), while the lowest dominance was at Barikot (0.04465). Conclusions: It has been concluded that tick diversity and distribution, abundance, reproduction, development, and survival depend on prevailing climatic conditions. The present study would not only help to identify the tick species but also facilitate in devising effective control measures to minimize the transmission pathogens in sheep and goats being reared in the various agro-climatic zones of KPK province, Pakistan.

Microhabitat factors associated with the habitat of barking deer (Muntiacus vaginalis) were examined and compared between summer and winter seasons. Habitat characteristics and preferred habitat were measured by locating direct and indirect signs. To quantify the habitat utilization of barking deer, each selected study site was sampled for floral diversity from 2015 to 2017. Quadrats were deployed along transect lines to determine seasonal distribution. Barking deer were not evenly distributed across vegetation types in the study area; they occurred more often in the broad-leaved forest than in Chir pine forest, at an elevational range of 550-850 m, in thick vegetation on steep slopes. The most preferred habitat included trees and shrubs with 30% and 69% cover, respectively. Barking deer avoided thicker tree cover, possibly as it hinders movement and escape from predators. No significant difference (χ2 = 6.37, df = 3, p = 0.19) in seasonal vegetation cover was recorded.

Black francolin or Black partridge (Francolinus francolinus L.) is distributed throughout Pakistan including Indus plains, Baluchistan, Punjab and Khyber Pakhtunkhwa provinces. Black francolin has been described as common or Least Concern in IUCN Red List of Threatened Species (2018). There was no documented information available on population density of Black francolin in various habitats of Kala Chitta hills of Pothwar region, Pakistan. Therefore, present study was designed to investigate the population of Black francolin in study area to devise conservation measures. Based on the reconnaissance survey, three representative sites were selected to estimate the population of black francolin in its potential habitat in Kala Chitta hills. Observations were taken by direct sighting using “Visual Encounter Method (VEM)”. The observations were taken along three fixed transects, having a length of 300 m and width varying from 20 to 50 m were laid down at each site to record the birds on or near the line. Overall, population density of Black francolin was recorded 1.06 birds/ha. Highest population density (2.19 birds/ha) was recorded in mountainous forest and associated grassland. While, population density of 0.84 and 0.15 birds/ha was recorded in open cultivated land and wetlands associated vegetation, respectively. It is concluded that Black francolin population density is affected by habitat characteristics in Kala Chitta Hills. Therefore, habitat characteristics must be considered while devising conservation plan for Black Francolin. Key words: Francolinus francolinus, Population, Kala Chitta, wetlands, mountainous forest
