Display Behavior and Habitat Use in Single and Mixed Populations of Anolis carolinensis and Anolis sagrei Lizards
AbstractIntroduced species can have a variety of effects on the behavior and ecology of native species. We compared display behavior and habitat use of introduced Anolis sagrei and native Anolis carolinensis lizards across three sites in Southern Louisiana. The chosen sites were similar in that they were all located in urban settings with clumped vegetation. The first site contained only A. sagrei, the second supported sympatric A. sagrei and A. carolinensis populations, and the third site harbored only A. carolinensis. We found that (1) A. carolinensis perched significantly higher when A. sagrei was present, consist...

Heterochronic shifts in the ossification sequences of surface- and subsurface-dwelling skinks are correlated with the degree of limb reduction.
Abstract Scincid lizards exhibit a variety of limb anatomies which reflect the functional requirements of different modes of life. Besides surface dwellers which show neither body elongation nor limb reduction, there are numerous examples that can be arranged as increasingly serpentiform taxa moving in sand, humus or leaf litter. We explored the question of whether limb reduction and body elongation in skinks are linked to heterochronic shifts in the ossification sequences. The study material comprises skinks showing four different morphotypes: Liopholis whitii, Lerista bougainvillii, Hemiergis peronii and Saiphos ...

Does syntax contribute to the function of duets in a parrot, Amazona auropalliata?
Abstract Complex acoustic signals in many animal species are characterized by a syntax that governs how different notes are combined, but the importance of syntax to the communicative function of signals is not well understood. Mated pairs of yellow-naped amazons, Amazona auropalliata, produce coordinated vocal duets that are used for territory maintenance and defense. These duets follow rules that specify the ordering of notes within duets, such as a strict alternation of sex-specific notes and a defined progression of note types through each duet. These syntactical rules may function to define sex-specific roles,...

Validation of diagnostic assays to screen broodstock for Flavobacterium psychrophilum infections
In this study, tissue and ovarian fluid samples were collected from 224 fish at five hatcheries and screened using an enzyme‐linked immunosorbent assay (ELISA), a membrane‐filtration fluorescent antibody test (MF‐FAT), bacteriological culture and nested PCR. Latent class analysis was used to estimate sensitivity and specificity of kidney culture, kidney ELISA, nested PCR and MF‐FAT. Analytical sensitivity of the ELISA varied but was greatest when bacteria were cultured under iron‐limiting conditions. Diagnostic sensitivity estimates ranged from 0.02 (kidney culture) to 0.97 (kidney ELISA). Specificity estimates r...

The fate of redundant cues during blocking and a simple discrimination.
In each of three experiments animals received blocking, A+ AX+, in which food was always presented after one stimulus, A, that was occasionally accompanied by another stimulus, X. They also received a simple discrimination, AX+ BX−, in which the presence and absence of food was signaled by two compounds that contained one unique cue, A or B, and one common cue, X. In each of these designs, X can be said to be redundant relative to A as a signal for food. Test trials at the end of training revealed that responding during X was stronger after blocking than after the simple discrimination. These results contradict predictio...

Re-assessing causal accounts of learnt behavior in rats.
Rats received either a common-cause (i.e., A→B, A→food) or a causal-chain training scenario (i.e., B→A, A→food) before their tendency to approach the food magazine during the presentation of B was assessed as a function of whether it was preceded by a potential alternative cause. Causal model theory predicts that the influence of an alternative cause should be restricted to the common-cause scenario. In Experiment 1, responding to B was reduced when it occurred after pressing a novel lever during the test phase. This effect was not influenced by the type of training scenario. In Experiment 2, rats were familiarized...

Prenatal and neonatal flutamide administration increases proliferation and reduces apoptosis in large antral follicles of adult pigs.
Abstract Ovarian follicular atresia is regulated by androgens directly via androgen receptors and indirectly after conversion to estrogens. The balance between proliferation and cell apoptosis is crucial for the physiological functioning of the follicles. The disorder between these processes leads to reproductive failure, such as cyst formation. Recent research suggests maternally or neonatally mediated effects of antiandrogen flutamide on reproductive functions during adulthood. Therefore, the current study was performed to determine whether late gestational or neonatal exposure to flutamide influences proliferati...

Biology and ecology of Appendiseta robiniae (Hemiptera: Aphidoidea) — an alien species in Europe
Abstract Elements of the biology and ecology of A. robiniae were studied in Poland during the period of 2008–2009. The term of spring hatching, number of generations per season, developmental time of particular generations, lifespan of specimens and fecundity of particular generations were all defined. The dynamics of the species’ occurrence on its host plant were also determined. The two-year study showed a maximum of 11 aphid generations can develop on Robinia pseudoacacia. Females of the second and third generations were found to be the most fertile. These findings indicate that the species has adapte...

Amplitude modulation of sexy phrases is salient for song attractiveness in female canaries (Serinus canaria).
Abstract Song discrimination and recognition in songbird species have usually been studied by measuring responses to song playbacks. In female canaries, Serinus canaria, copulation solicitation displays (CSDs) are used as an index of female preferences, which are related to song recognition. Despite the fact that many studies underline the role of song syntax in this species, we observed that short segments of songs (a few seconds long) are enough for females to discriminate between conspecific and heterospecific songs, whereas such a short duration is not sufficient to identify the syntax rules. This suggests that...
