We are very proud to announce that Biologic now sponsor the only ALL GIRLS, under 12s Baseball team in Western Australia; Wembley Magpies.

Before Biologic's sponsorship the girls were using equipment that was too big and heavy, and gear that did not fit properly. Now the girls have batting helmets and catchers gear that fits and lightweight bats the right length for hitting home runs!

We wish the girls all the best for the season.

 

A Global Review of Lizard Clutch Sizes

In a new paper recently published in the journal Global Ecology and Biogeography, Biologic Senior Zoologist Ryan Ellis and group of international collaborators presented the results of a global review of lizard clutch sizes and what influences their diversity and distribution.

 The paper, titled The global diversity and distribution of lizard clutch sizes found that lizards generally lay larger clutches at higher altitudes, and in more productive and seasonal environments, showing a similar pattern to that seen in birds. Species occurring at low altitudes and on islands tend to lay smaller fixed sized clutch sizes. Environmental influences such as temperature and precipitation was not shown to be related to clutch size overall. With the exception of Africa, these patterns were consistent across continents where lizards occur. In Africa however, clutch sizes were often larger at lower altitudes.

 This led the authors to suggest that shorter activity seasons and the abundance of resources were the main drivers for species evolving to produce larger clutches in higher altitude and highly seasonal regions, and that the occurrence of these conditions may also be unfavorable for, and therefore influence the limited distribution of, fixed-clutch species.

Congratulations to Biologic’s zoologist Tom Rasmussen, who is the co-author of a recently published paper “ A large-scale automated radio telemetry network for monitoring movements of terrestrial wildlife in Australia”.

The paper discusses a rapidly expanding cooperative automated radio-tracking global network (Motus) which Tom helped to introduce to Australia and which Biologic have used to monitor movements of multiple threatened species in WA.
