RESUMO
The current research work aims to provide knowledge about the diversity of spiders' fauna and their occurrence throughout the year from District Charsadda Khyber Pakhtunkhwa, Pakistan. Research data were collected from March-2015 to January-2017 from seven different localities of Charsadda District by using the camera, bottle, plastic bags, paraffin films, field book and 70% of ethylene alcohol and 20% of glycerine were used as chemicals. By using special identification keys, spiders were differentiated into families, genera and species. During the study time, a total of 2734 specimens of spiders were collected belonging from 35 genera, 15 families and 44 species were identified. Salticidae was the dominant family according to genera studied plus spiders samples numbers collected with 10 genera and 616 species specimens count. The high occurrence of spiders was studied during July. The result of the current study also shows a reduction of spider's species in December due to lowering the temperature. The current study shows that Salticidae were the dominant family as capered to other species. The occurrence of spiders species greatly depends on changing the weather condition. The present study also shows great fluctuation in spider's occurrence with changing of hot climate to colder during the study duration. Moreover, the wet season plays a great role in spiders' population increase and growth.
O objetivo do presente trabalho de pesquisa é fornecer conhecimento sobre a diversidade da fauna de aranhas e sua ocorrência ao longo do ano no distrito Charsadda Khyber Pakhtunkhwa, Paquistão. Os dados da pesquisa foram coletados no período de março de 2015 a janeiro de 2017 em sete diferentes localidades do distrito de Charsadda por meio de câmera, garrafa, sacos plásticos, filmes de parafina, livro de campo, e 70% de álcool etílico e 20% de glicerina foram utilizados como produtos químicos. Usando chaves de identificação especiais, as aranhas foram diferenciadas em família, gênero e espécie. Durante o período de estudo foram coletados 2.734 espécimes de aranhas pertencentes a 35 gêneros, 15 famílias e 44 espécies. Salticidae foi a família dominante de acordo com os gêneros estudados mais o número de amostras de aranhas coletadas com 10 gêneros e contagem de 616 espécies. Altas ocorrências de aranhas foram estudadas durante o mês de julho. O resultado do estudo atual também mostra redução das espécies de aranhas no mês de dezembro devido à diminuição da temperatura. O estudo atual mostra que os Salticidae foram a família dominante como alcaparras para outras espécies. A ocorrência de espécies de aranhas depende muito da mudança das condições climáticas. O presente estudo também mostra grande flutuação na ocorrência de aranhas com a mudança do clima quente para mais frio durante a duração do estudo. Além disso, a estação chuvosa desempenha um grande papel no aumento e crescimento da população de aranhas.

Despite scorpion diversity has long been acknowledged, the mystery of how it develops remains unresolved. The geographical distribution, species abundance and biodiversity of scorpions fauna in Khyber Pakhtunkhwa is poorly explored with many aspects like morphological, geographical, ecological and phylogenetically. As a result of faunaistic study on scorpions a total of 171 specimens from various regimes, Charsadda, Mardan, Peshawar and Kohat districts of Khyber Pakhtunkhwa, Pakistan from March 2018 to October 2018 were collected. GarminTM GPS V Plus device. The software Arc GIS 10.2 was used to create maps of the study areas. Pitfall traps were used to gather samples from sandy habitats and pastureland. Five species Hottentotta tamulus Fabricius, 1798, with (35%), Scorpiops pseudomontanus Kovarik and Ahmed, 2009, (26%), Orthochirus fuscipes Pocock, 1900, (15%), Hottentotta buchariensis Birula, 1897, (13%) and Deccanometrus latimanus Pocock, 1894, (11%) were detected in our proposed study. The research indicates that abundance and temperature have a favorable connection, while abundance and humidity get a negative correlation. The value of evenness shows the strong equilibrium between the effectiveness of sampling species, and the Shannon's index suggests that the Pakistani region has a high level of scorpion variety.
Apesar de a diversidade de escorpiões ser reconhecida há muito tempo, permanece sem solução o mistério de como eles se desenvolvem. A distribuição geográfica, a abundância de espécies e a biodiversidade da fauna de escorpiões em Khyber Pakhtunkhwa são pouco exploradas quanto a aspectos morfológicos, geográficos, ecológicos e filogenéticos. Como resultado do estudo faunístico em escorpiões, foi coletado um total de 171 espécimes de vários regimes nos distritos de Charsadda, Mardan, Peshawar e Kohat, de Khyber Pakhtunkhwa, Paquistão, de março de 2018 a outubro de 2018. Dispositivo GarminTM GPS V Plus. O software Arc GIS 10.2 foi utilizado para criar mapas das áreas de estudo. Armadilhas de queda foram usadas para coletar amostras de habitats arenosos e pastagens. Cinco espécies Hottentotta tamulus Fabricius, 1798 (35%), Scorpiops pseudomontanus Kovarik and Ahmed, 2009 (26%), Orthochirus fuscipes Pocock, 1900 (15%), Hottentotta buchariensis Birula, 1897 (13%) e Deccanometrus latimanus Pocock, 1894 (11%) foram detectados em nosso estudo proposto. A pesquisa indica que abundância e temperatura têm uma relação favorável, enquanto abundância e umidade têm uma correlação negativa. O valor da uniformidade mostra o forte equilíbrio na eficácia da amostragem de espécies, e o índice de Shannon sugere que a região paquistanesa tem um alto nível de variedade de escorpiões.
