The influence of ecological factors on mosquito abundance and occurrence in Galápagos [PDF]
Journal of Vector Ecology, 2018 We sampled mosquitoes across 18 sites established at different elevations and stretching from the north to the south of Isla Santa Cruz, Galápagos. Two commonly occurring species, Ae. taeniorhynchus and Cx. quinquefasciatus, were collected along with environmental variables characteristic of the trapping sites to assess their influence on mosquito ...

The effect of population abundances on the stability of large random ecosystems [PDF]
Phys. Rev. E 98, 022410 (2018), 2017 Random matrix theory successfully connects the structure of interactions of large ecological communities to their ability to respond to perturbations. One of the most debated aspects of this approach is the missing role of population abundances. Despite being one of the most studied patterns in ecology, and one of the most empirically accessible ...

Obesity alters gut microbial ecology.
Proceedings of the National Academy of Sciences of the United States of America, 2005 We have analyzed 5,088 bacterial 16S rRNA gene sequences from the distal intestinal (cecal) microbiota of genetically obese ob/ob mice, lean ob/+ and wild-type siblings, and their ob/+ mothers, all fed the same polysaccharide-rich diet.

Emergence of structural and dynamical properties of ecological mutualistic networks [PDF]
Nature, 500 (449), 2013, 2013 Mutualistic networks are formed when the interactions between two classes of species are mutually beneficial. They are important examples of cooperation shaped by evolution. Mutualism between animals and plants plays a key role in the organization of ecological communities.

Abundance, ecology and dispersal of wood bison (Bison bison athabascae Rhoads) in Yakutia
ARCTIC AND SUBARCTIC NATURAL RESOURCESIn 2006, 2011, 2013, and 2020, four groups of young wood bison, each made up of 30 individuals from Canada, were introduced to Yakutia. The bison began to reproduce at ages 2 to 3 in 2008. Their mating behavior was first noted in 2007 when they were 2 to

Environmental DNA, 2022 A greater understanding of eDNA behavior in the environment is needed before it can be employed for ecosystem monitoring applications. The objectives of this study were to use autonomous sampling to conduct long‐term, high‐frequency monitoring of the ...

Linearity and Scaling of a Statistical Model for the Species Abundance Distribution [PDF]
, 2001 We derive a linear recursion relation for the species abundance distribution in a statistical model of ecology and demonstrate the existence of a scaling solution.

Parasite abundance and diversity in mammals: correlates with host ecology. [PDF]
Proceedings of the National Academy of Sciences, 1995 Fecally dispersed parasites of 12 wild mammal species in Mudumalai Sanctuary, southern India, were studied. Fecal propagule densities and parasite diversity measures were correlated with host ecological variables. Host species with higher predatory pressure had lower parasite loads and parasite diversity.

Road Zone Effects in Small-Mammal Communities
Ecology and Society, 2009 Our study focused on the putative effects of roads on small-mammal communities in a high desert region of southern Utah. Specifically, we tested whether or not roads create adjacent zones characterized by lower small- mammal densities, abundance, and ...

Can Rock-Rubble Groynes Support Similar Intertidal Ecological Communities to Natural Rocky Shores?
Land, 2020 Despite the global implementation of rock-rubble groyne structures, there is limited research investigating their ecology, much less than for other artificial coastal structures. Here we compare the intertidal ecology of urban (or semi-urban) rock-rubble
