Avian species are commonly infected by multiple parasites, however few studies have investigated the environmental determinants of the prevalence of co-infection over a large scale. Here we believe that we report the first, detailed ecological study of the prevalence, diversity and co-infections of four avian blood-borne parasite genera: Plasmodium spp., Haemoproteus spp., Leucocytozoon spp. an...
An eco-epidemiological study was carried out in the region of the Alpujarras (southern Spain, Granada province). Nine villages were chosen at random in 5 bioclimatic zones. A study of leishmaniasis in the canine and human populations, was carried out concentrating especially upon schoolchildren. A total of 615 dogs were screened, which represents almost 100% of the canine census. Of the screene...
It has long been considered sufficient a single method or only a descriptive diagnosis to propose a new species. Recently, many works have proposed new theoretical paradigms to consider multiple sources of evidence to support the hypothesis of new taxa within an integrative approach. Despite this, many new described species continue to be merely descriptive and without any reproducible statisti...
Species Distribution Models (SDMs) combine information on the geographic occurrence of species with environmental layers to estimate distributional ranges and have been extensively implemented to answer a wide array of applied ecological questions. Unfortunately, most global datasets available to parameterize SDMs consist of spatially interpolated climate surfaces obtained from ground weather s...
Weather condition is one of the much effective factors in the principle of architecture and urbanization. So in this research long-term trend of effective climate elements in architecture of Darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...
Aim The environmental preferences of species are an important facet their response to changing conditions, and these have long been thought exhibit phylogenetic conservatism. However, bioclimatic envelopes not previously imputed from climate records at the date location occurrence, strength signal has studied a broad scale. Here, we combine global reconstructions with contemporaneous plant occu...
Aim It is important to understand the factors affecting community stability because ecosystem function increasingly at risk from biodiversity loss. Here, we evaluate how a key factor, position of local environmental conditions within thermal range species, influences butterfly communities continental scale. Location Spain, UK and Finland. Time period 1999–2017. Major taxa studied Butterflies. M...
