Despite its size, many feel the illegal trade in wildlife is not getting the attention or resources it deservesOpening the door to the animal house, passing a rhino on the way and patting the giraffe inside, Sarah Forsyth points out small white boxes that dot the walls. "Everywhere you look there's a detector or a motion sensor," she says, chuckling in front of one that presented the security firm with a peculiarly zoo-specific problem. "These are the ones the giraffe were licking."She can laugh about it now, but two months ago, when Colchester zoo decided to put in place its new £300,000 alarm system, Forsyth's overridin...

We've had some unexpected animal run-ins at Dartmoor zoo – it can be an unforgettable educational experienceWhen I heard that Colchester zoo had lost one of its owls to one of its lions, my first thought was: "That could have been us, or any other zoo in the country." Although our falcon display takes place a good distance from the bears, wolves, lions and tigers, the birds do sometimes become distracted and make forays into areas they shouldn't.Fortunately, so far, they have always – eventually – returned to the capable gauntlet of David our falconer. Being on the edge of Dartmoor, where big buzzards and falcons are...

SummaryOligoryzomys (Cricetidae, Sigmodontinae) is a common rodent genus from South America that includes a couple of very similar species. Related species have been used as experimental model for understanding several diseases for which these species are reservoirs. In order to provide a better understanding of the embryological aspects of this group, herein we showed data on the embryonic and fetal development in Oligoryzomys sp. Eight specimens of different stages of gestation were obtained from the Collection of the Zoology Museum of University of Sao Paulo, Brazil. Gestational ages were estimated by crown‐rump‐len...

Discuss or comment on this article.
AbstractComplex courtship signals can be dissected into distinct components that can either function independently or via interactions with one another. Male Rabidosa rabida wolf spiders use courtship displays that couple a seismic signal with the waving of an ornamented foreleg. While previous studies suggest that female R. rabida exhibit mate choice and that both the seismic and visual modalities are important in mating interactions, it remains unclear how variation in each component influences female mating decisions. To investigate this, we ran two separate experiments in which we manipulated (1) male diets, to induce...

AbstractSexual selection theory suggests males in good condition should be more successful than males in poor condition when competing with rivals for territories and mates. Understanding how condition influences the interplay between aggression, mate attraction, and courtship displays could help explain why variation is maintained in traits that confer fitness. Using laboratory‐reared Jamaican field crickets, Gryllus assimilis, we found that fine‐scale temporal components of mate attraction signals were positively correlated with body condition (residual body mass) and body size; signaling effort was positively correl...

ABSTRACTNine multiparous Holstein cows were used in a replicated 3 × 3 Latin square design to determine the effects of substituting corn grain with brown rice (BR) grain in total mixed ration (TMR) silage on milk yield, ruminal fermentation and nitrogen (N) balance. The TMR silages were made from the ensiling of TMR containing (dry matter basis) 50.1% forage in rice silage and corn silage combination, and 49.9% concentrate. The grain portion of the diets contained 31.2% steam‐flaked corn, 31.2% steam‐flaked BR or an equal mixture of corn and BR. Dietary treatments did not affect dry matter intake, milk yield and m...

ABSTRACTThe aim of the present study was to clarify the effect of photoperiod on the secretion of growth hormone (GH) in goats. Adult female goats were kept at 20°C with an 8‐h or 16‐h photoperiod, and secretory patterns of GH for 4 h (12.00 to 16.00 hours) were compared. In addition, the goats were kept under a 16‐h photoperiod and orally administered saline (controls) or melatonin, and the effects of melatonin on the secretion of GH were examined. GH was secreted in a pulsatile manner. There were no significant differences in pulse frequency between the 8‐ and 16‐h photoperiods; however, GH pulse amplitude t...

ABSTRACTFibroblast growth factor 4 (FGF4) is considered as a crucial gene for the proper development of bovine embryos. However, the complete nucleotide sequences of the structural genes encoding FGF4 in identified breeds are still unknown.

On the other hand, differences in the nucleotide sequences, leading to substitutions, inserti...

Everybody Needs Good Neighbours: Coalition Formation Influences Floater Fight ChoiceEmail this article to a colleague.

AbstractIn territorial species, it is sometimes less costly to help a neighbour fight off an intruder than to re‐establish territory boundaries with a new, potentially stronger neighbour. In fiddler crabs, a male resident will only help his neighbour if he is larger than the intruder who, in turn, is larger than the challenged neighbour. Does this influence with whom a territory‐seeking male decides to fight? I show that territory‐seeking males appear to choose opponents based partly on the size of the resident’s nearest neighbour. By avoiding challenging resident males with larger neighbours, territory‐seeking m...

We present a Tg(tnks1bp1:EGFP) stable transgenic line, which we used to establish a transcriptional profile of supporting cells in the zebrafish lateral line. Therefore we are providing a new set of markers specific for supporting cells as well as candidates for functional analysis of this important cell type. This will prove to be a valuable tool for the study of regeneration in the lateral line of zebrafish in particular and for regeneration of neuroepithelia in general.

Conclusions:
The model results indicate that land development in the Cape Peninsula has pushed baboons into increasingly marginal natural habitat while simultaneously providing them with predictable and easily accessible food sources in human-modified habitats. The resultant spatial competition between humans and baboons explains the high levels of human-baboon conflict and further erosion of the remaining land fragments is predicted to exacerbate competition. This study demonstrates how the quantification of animal landscape requirements can provide a mechanism for identifying priority conservation areas at the human-wild...

Conclusion:
Adenosine increased the cell division timings thereby making large number of cells available for aggregation and also it marginally increased the cell size contributing to large aggregate size. Reduced cell division rates and decreased cell size in the presence of caffeine makes the aggregates smaller than controls. Both the compounds altered the speed of the chemotactic amoebae causing a variation in aggregate size. Our data strongly suggests that cytosolic glucose and extracellular cAMP levels are the other major determinants regulating aggregate size and pattern. Importantly, the aggregation process is conse...

Conclusion This meta-analysis suggests that p53 codon 72 Pro/Pro + Arg/Pro genotypes are associated with increased risk of endometriosis
in Asian. To validate the association between p53 codon 72 polymorphism and endometriosis, further studies with larger participants
worldwide are needed.

The pheromones of laying workers in two honeybee sister species: Apis cerana and Apis melliferaEmail this article to a colleague.

Abstract When a honeybee colony loses its queen, workers activate their ovaries and begin to lay eggs. This is accompanied by a shift
in their pheromonal bouquet, which becomes more queen like. Workers of the Asian hive bee Apis cerana show unusually high levels of ovary activation and this can be interpreted as evidence for a recent evolutionary arms race
between queens and workers over worker reproduction in this species. To further explore this, we compared the rate of pheromonal
bouquet change between two honeybee sister species of Apis cerana and Apis mellifera under queenright and queenless conditions. ...

A winter walk through the hills near the Natural History Museum in TringIf you're like me, you're probably wondering what happened to winter this year. In my neck of the woods, we had a light dusting of snow that lasted for roughly three hours this winter season, and it doesn't look as though any more is on the way. So if you're missing snow, here's a nice little video, courtesy of the Natural History Museum in Tring, of a winter walk around the snowy hills of Tring with museum botanist Fred Rumsey: Visit NaturalHistoryMuseum's YouTube channel [video link].
