The Aromatic Head Group of Spider Toxin Polyamines Influences Toxicity to Cancer Cells

open access: yesToxins, 2017
Spider venoms constitute incredibly diverse libraries of compounds, many of which are involved in prey capture and defence. Polyamines are often prevalent in the venom and target ionotropic glutamate receptors. Here we show that a novel spider polyamine,

Spider Venoms Potentially Lethal to Humans

open access: yes, 2013
Spiders have one pair of venom glands, and only a few families have reduced them completely (Uloboridae, Holarchaeidae) or modified them to another function (Symphytognathidae or Scytodidae, see Suter and Stratton 2013).

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Spider venom [PDF]

open access: yes, 2012
Pauci su jedna od evolucijski najuspješnijih skupina životinja. Najvažnije prilagodbe koje su im omogućile veliku raširenost i raznolikost su sposobnost izgradnja mreža od svile i uporaba otrova u savladavanju plijena i samoobrani.

Main Components of Spider Venoms

open access: yes, 2013
Venom glands are alreadypresent in theoldes t spider group, the Mesothelae. Theglands lie in the anterior portion of the cheliceral basal segment but are very small, and it is doubtful how much the venom contributes to the predatory success.

A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

open access: yesOikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

The lethal toxin from Australian funnel-web spiders is encoded by an intronless gene. [PDF]

open access: yesPLoS ONE, 2012
Australian funnel-web spiders are generally considered the most dangerous spiders in the world, with envenomations from the Sydney funnel-web spider Atrax robustus resulting in at least 14 human fatalities prior to the introduction of an effective anti ...

Examining the multi‐disciplinary origins of biophobia towards threatening and non‐threatening wildlife in a highly urbanised city in China

open access: yesPeople and Nature, EarlyView.
Abstract Urbanisation is reshaping how people experience wildlife, reducing our shared spaces with local biodiversity. Fewer opportunities for human–wildlife interactions weaken our emotional attachments to nature and precipitate a loss of species knowledge and familiarity.
