A meta-analysis of host specificity in Neotropical hard ticks (Acari: Ixodidae) [PDF]

open access: yes, 2013
Host specificity of Neotropical hard ticks (Acari: Ixodidae) was analyzed by using the number of hosts species for each tick species and the index of host specificity STD*, which integrates phylogenetic and ecological information. The analyses were based

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Comparative tests of ectoparasite species richness in seabirds [PDF]

open access: yes, 2007
Background: The diversity of parasites attacking a host varies substantially among different host species. Understanding the factors that explain these patterns of parasite diversity is critical to identifying the ecological principles underlying ...

THE BASIC FUNCTIONS OF SOUND SIGNALS IN MAMMALS

open access: yesRUDN Journal of Ecology and Life Safety, 2016
All the diversity of sound signals by mammals is subordinated two basic functions: function implementation of the populations of genotype and function realization of the ecological niche of species populations. The basic functions have resulted from some

An Exploratory Investigation into the Effects of Methanol and Ethylene Glycol on the Growth and Development of Medaka (Oryzias melastigma) and Yellowstripe Goby (Mugilogobius chulae)

open access: yesToxics
This study aimed to investigate the acute and chronic toxic effects of two thermodynamic inhibitors (methanol and ethylene glycol) widely used in deep-sea oil and gas operations on two typical marine fish species, the medaka (Oryzias melastigma) and the ...

Four new species of Brueelia Kéler, 1936 (Phthiraptera: Ischnocera) from African hosts, with a redescription of Nirmus bicurvatus Piaget, 1880

open access: yesEuropean Journal of Taxonomy, 2019
Four new species of Brueelia Kéler, 1936 are described and illustrated. All of them parasitize African endemic host species in the families Passeridae, Ploceidae, and Estrildidae (Passeriformes). They are: Brueelia pofadderensis sp. nov.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The wine microbial consortium: a real terroir characteristic

open access: yesOENO One, 2006
Yeast, bacteria, species and strains play a key role in the winemaking process by producing metabolites, which determine wine sensorial qualities. Therefore microbial population enumeration, species identification and strain discrimination from berry ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Ecology of the (Brady)rhizobium symbiotic relationship with Fabaceae in the south-western Cape [PDF]

open access: yes, 1996
The mediterranean ecosystems of the south-western Cape, South Africa occur mainly on nutrient-poor acid sands and less often on limestone and mixed limestone soil types which support a high species diversity of Fabaceae.
