... aurea was once abundant, there is some suspicion that G. holbrooki's non-specific predatory behaviour may be instrumental in the decline of L. aurea . Laboratory and field experiments were conducted to assess the impact of G. holbrooki predation on L. aurea tadpole survivorship. Laboratory trials...

... chain in the aquatic environment, once in the terrestrial environment, turtles are highly vulnerable to predation (Segura et al. 2020; Spencer and Thompson 2003; Tucker and Janzen 1999). Freshwater turtle life histories are characterised by long generation times, high adult survivorship, late age...

... population abundance. The second was a reduction in the abundance of juvenile turtles over time. Drought may have reduced critical habitat for C. longicollis, which had reduced both its total numbers and survivorship of juveniles (Chessman 2011). Likewise, E. macquarii had suffered from both the effects...

... to this, 492 woylies Bettongia penicilata were translocated into each treatment area to determine their survivorship in the face of different fox densities, and common brushtail possums Trichosurus vulpecula were collared in-situ to assess the survivorship of arboreal fauna (de Tores 1999). Bird surveys...

... are for survivorship are unclear. The fact that females tended to have smaller fat bodies more often than did males is consistent with the notion that females may be using the materials in their fat bodies to produce their eggs. The lack of any variation in the number of phalanges in either the front or rear foot...

... investigation. Little is known about the interactions between the two species and given the potential negative implications on a threatened species survivorship or habitat selection, we suggest experimental studies are needed. A mark-recapture and movement study (e.g. radio telemetry) would clarify the extent...

Additionally, if anemonefish are lost because of retraction or death of anemones, surviving anemones will likely have lower survivorship even if conditions remain optimal 2024 AuZstoraolilaongist volume...

... be obtained from mark-recapture studies that allow detection probabilities to be quantified, but these remain estimates with error variances (e.g., Meyler et al. 2012). Furthermore, some marking techniques may reduce survivorship (Ribeiro and Sousa 2006), and some small or juvenile lizards are notoriously...

... over the treatment. Transmission of UV-B was reduced from 80% to 50Vo in the control filters over the period of the experiment, but one would still expect to see a difference in survivorship between the UV-B- blocking and control filters when 50% UV-B was being. transmitted. .Also, the first l...
