behaviour of sympatric Norops humilis and N. limifrons lizards were studied. Lizard microhabitats were categorized and approach speeds were randomised such that each lizard was approached at one of two speeds, slow or fast. Approach speed of a simulated predator had no significant effect on approach

signiŽ cant positive relationship between standard length and horizontal and vertical area use and time spent moving. In addition, there was a signiŽ cant effect of body type, with bass with deeper body morphs shifting from antipredator to foraging responses earlier than those with shallower body morphs

the pedicel, shaft, or pedicel shaft junction were observed. Hypertrophy of the horizontally ankylosed vomerine teeth is associated with a distortion of the underlying vomer. This suggests that alterations in odontogenesis may effect changes in the morphogenesis of underlying dentigerous bones

specimens were collected in March and July of 2015 in both lagoons, from the catches made by artisanal fishermen. The two lagoons have a sandbar that connects periodically with the sea because of the effect of storms, rainfall over the basin and/or human action (Conde & Sommaruga, 1999; Santana & Fabiano

negative relationship (Snaith et al., 2008). Two recent meta-analyses found evidence for a small to moderate effect size relating network size and parasitism, but with many studies showing exceptions to this overall association (Rifkin et al., 2012; Patterson & Ruckstuhl, 2013). One factor that may play a

Hans effect in dogs Figure 1. The mean number ( + SE) of correct choices ( N = 15 in each group). The horizontal line shows the chance level. There was no significant difference among the groups (one- way ANOVA). Markings within the bars show the results of one-sample t -tests: ∗ p < 0 . 05; ∗∗ p < 0

horizontally for approximately 4–6 m before again sloping upwards. The top of the nesting area is bordered by a concrete retaining wall that restricts turtles from moving outside the area onto a road. Most of the nesting area is characterized by sandy soil with open and grassy areas, but there are also several

We distinguish the proportion of present year individuals (clear area with horizontal lines); first year individuals (intermediate dark area with vertical lines) and second

. The webs of T. arawari are not very sticky, whereas both A. katherina and Purumitra sp. build sticky orb webs (of vertical and horizontal orientation, respectively). The webs of Purumitra sp. are built with cribellate silk that confers dry ad- hesion and the webs of A. katherina are built with
