Amazonian countries have historically sourced the international wildlife trade. However, little is known about their domestic trade, which often overlooked in estimates of trafficking. Peruvian law prohibits unauthorized trade and possession wildlife, but illegal sales are common urban markets. To describe dynamics, diversity, composition this we surveyed live for sale markets 16 departments from 2007 to 2012. We identified main hotspots market trafficking, detected 193 species being sold...
Abstract Biological invasions by exotic species impose substantial ecological, economic and social costs worldwide, being a major threat to biodiversity conservation. Because not all individuals introduced in the new environments become successful invaders, identification of factors underlying variation invasion success would be essential for evaluating risk. Here, we test several host–parasite hypotheses accounting house sparrows Passer domesticus Peru. According Enemy Release Hypothesi s,...
Abstract Aim The increasing spread of vector‐borne diseases has resulted in severe health concerns for humans, domestic animals and wildlife, with changes land use the introduction invasive species being among main possible causes this increase. We explored several ecological drivers potentially affecting local prevalence richness avian malaria parasite lineages native introduced house sparrows ( Passer domesticus ) populations. Location Global. Time period 2002–2019. Major taxa studied...
Characterizing the diversity and structure of host-parasite communities is crucial to understanding their eco-evolutionary dynamics. Malaria related haemosporidian parasites are responsible for fitness loss mortality in bird species worldwide. However, despite exhibiting greatest ornithological biodiversity, avian haemosporidians from Neotropical regions quite unexplored. Here, we analyze genetic (Plasmodium Haemoproteus) 1,336 individuals belonging 206 explore differences parasite lineages...
Chlamydiaceae bacteria infect many vertebrate hosts, and previous reports based on polymerase chain reaction (PCR) assays serologic that are prone to cross-reaction among chlamydial organisms have been used describe the prevalence of either DNA fragments or antibodies Chlamydia spp. in wild raptorial populations. This study PCR-based does not 100% match any avian mammalian populations hawks California Buteo species. In this study, multimucosal swab samples (n = 291) for quantitative PCR...
En el presente estudio se da a conocer doce especies de malófagos colectados en aves mantenidas cautiverio manera temporal o permanente Perú. Cuatro Amblycera: Colpocephalum turbinatum, Psittacobrosus amazonicus, burmeisteri y Kurodaia sp., así como ocho Ischnocera: Neopsittaconirmus gracilis, Paragoniocotes fulvofasciatus, mirabilis, nanus, neivai, pyrrhurae, Philoceanus amadoni Quadraceps burhinoides, fueron identificados mediante diagnóstico morfológico. Se realiza una breve descripción...
Abstract Parasites are globally widespread pathogenic organisms, which impose important selective forces upon their hosts. Thus, in accordance with the Adjustment to parasite pressure hypothesis, it is expected that defenses among hosts vary relative imposed by parasites. According latitudinal gradient diversity, species richness and abundance of parasites peak near equator. The uropygial gland an defensive exocrine against pathogens birds. Size has been proposed birds because divergent...
Las lesiones patológicas causadas por acantocéfalos en aves marinas son poco conocidas. En este sentido, se presenta un estudio de las una gaviota gris (Leucophaeus modestus) (Tschudi, 1843) el acantocéfalo Profilicollis altmani (Perry, 1942) Van Cleave, 1947. Macroscópicamente, encontró engrosamiento la pared intestinal circunscrito a profunda área penetración los gusanos, con nódulos blanquecinos serosa. Microscópicamente, observó del extremo anterior vellosidades intestinales y submucosa,...
Atherosclerosis is a chronic inflammatory disease that has been reported to affect the cardiovascular system of many avian species. However, atherosclerosis in raptor species not fully evaluated. The aim this study was histologically characterize central and peripheral atherosclerotic lesions raptors were submitted pathology service Northern California from 1986 2013. We also evaluated risk factors, including age, gender, origin, family. Atherosclerotic categorized as minimal, mild,...
Microplastics are tiny plastic pieces, <5 mm, which is smaller than a pencil eraser. Did you know that can find microplastics everywhere? They in the air, water, soil, and within living creatures. You them from deep sea to snow Arctic. across beaches California, San Francisco Bay waters. Many organisms ranging zooplankton whales contain their bodies, including aquatic creatures California. In this article, will learn about origin of microplastics, where them, why they concern, how...
