Host-parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati). [PDF]

Med Vet Entomol
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Estimating the cumulative impact and zone of influence of anthropogenic features on biodiversity

Methods in Ecology and Evolution, Volume 14, Issue 9, Page 2362-2375, September 2023., 2023
Abstract The concept of cumulative impacts is widespread in policy documents, regulations and ecological studies, but quantification methods are still evolving. Infrastructure development usually takes place in landscapes with preexisting anthropogenic features. Typically, their impact is determined by computing the distance to the nearest feature only,

Effects of forest fragmentation on the weight of understory birds at the Biological Dynamics of Forest Fragments Project in Amazonia

Biotropica, Volume 54, Issue 4, Page 852-859, July 2022., 2022
Deforestation and habitat fragmentation are known as the chief drivers of biodiversity loss. Habitat fragmentation in the Brazilian Amazon was found to affect the weight of birds that remained in isolated areas. Our results provide a novel analysis into how avian body mass responds to habitat fragmentation.

Timing and magnitude of climate‐driven range shifts in transboundary fish stocks challenge their management

Global Change Biology, Volume 28, Issue 7, Page 2312-2326, April 2022., 2022
We use model projections to explore the timing and intensity in the distribution of marine fish stocks that are shared across the world's Exclusive Economic Zones (EEZ). Our findings suggest that many shared stocks’ distribution and catch are expected to change in most EEZs by 2030.

Ecological aspects of Aphidius colemani Viereck (Hymenoptera: Aphidiidae) on the Sitobion avenae (Fabricius) (Hemiptera: Aphididae) population in wheat culture in Medianeira, PR./
Aspectos ecológicos de Aphidius colemani Viereck (Hymenoptera: Aphidiidae) sobre a população de Sitobion avenae (Fabricius) (Hemiptera: Aphidiidae) na cultura de trigo em Medianeira, PR

Semina: Ciências Agrárias, 2006
Aphids were the main winter-cereal problem in the 70’s in southern Brazil and it was necessary to use chemical control to avoid losses. Based in the weak performance of native parasites, 14 species of exotic parasites were introduced in 1978, and in 1984
