Fig. 1 in Revision of the South American Ninetinae genus Guaranita (Araneae, Pholcidae)
Fig. 1. NJ tree of CO1 barcodes using MEGA11. We applied the Kimura 2-parameter model (Kimura 1980) and the strategy of pairwise deletion of ambiguous positions to calculate the genetic distances between different specimens, from which the NJ-tree was constructed (500 bootstrap replicates). Tree scale = 0.05.
Fig. 2 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 2. Tb of Dorisiana bonaerensis during a light rain under a heavy overcast on the 21st December 1986. These animals were not exposed to direct solar radiation before the Tb was recorded. Closed circles, represent body temperatures of singing D. bonaerensis; open circles, represent body temperatures of D. bonaerensis engaged in other activities (including no activity). Details as in Fig. 1.
Fig. 3 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 3. Distribution of Dorisiana bonaerensis Tb as a function of Ta. The slope of the linear regression for "active" animals (closed circles) is significantly different from one, suggesting thermoregulation. The slope of the linear regression for "inactive" animals (open circles) is not significantly different from one, suggesting no thermoregulation is occurring.
Fig. 4 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 4. Distribution of Tb of as a function of Ta when Dorisiana bonaerensis were not exposed to solar radiation. The slope of the linear regression for " active " animals (closed circles) is significantly different from one, suggesting thermoregulation is occurring with endogenous heat. The slope of the linear regression for " inactive " animals (open circles) is not significantly different from one, suggesting no thermoregulation is occurring when the animals do not generate heat for activity.
Fig. 1 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 1. Diurnal distribution of Tb of Dorisiana bonaerensis and Quesada gigas on the 13th December 1986. A rainstorm from 07.00 to 08.00 h followed by a misting rain until 09.45 h delayed the start of activity approx. 2 h. Body temperatures are below ambient temperature before activity begins. Body temperatures are elevated at the start of activity (10.00 h) and regulated throughout the day. Body temperatures of quiescent animals decrease with ambient temperature after sunset (20.10 h). Animals participating in the evening chorus have body temperatures in or near the body temperature range measured during the day. Closed circles, Tb of singing D. bonaerensis; open circles, Tb of D. bonaerensis engaged in other activities (including no activity); closed triangles, Tb of singing Q. gigas; open triangles, Tb of Q. gigas performing other activities; solid line, ambient air temperature.
