Figure 2 in Nesting biology of the plain-throated Antwren (Isleria hauxwelli): an antbird with exceptional life history traits
Figure 2. Nest attentiveness throughout the incubation period for one nest of the Plain-throated Antwren (Isleria hauxwelli) located in the buffer zone of Manu National Park, Peru. A Generalised Linear Model for nest attentiveness using sensor data (black) and camera trap data (grey) was fitted to the data. Each dot represents the percentage of time spent in the nest per day. Pearson correlation coefficient was calculated for the nest attentiveness estimated from sensor data (Pearson' r = 0.68, p <0.01).

Including the incubation (a-b), brooding (c-d), provisioning for nestling (e) and foraging trips (f). Females are indicated by blue triangles and males are indicated by black circles. Grey shading indicates 95% confidence interval. Observations were made by camera trapping of nests located at 400 m.a.s.l. in the buffer zone of Manu National Park, Peru.
Figure 4 in Nesting biology of the plain-throated Antwren (Isleria hauxwelli): an antbird with exceptional life history traits
Figure 4. Nestling development of the plain-throated Antwren (Isleria hauxwelli). Day 1 nestlings were naked with dusky grey skin, the next day the buds of pin feathers were visible under the skin. Day 3 the first pin feathers erupt and started growing rapidly. Day 4 the buds of pin feathers were visible under the skin; after two days the first pin feathers erupt and started growing rapidly. At day 7 feathers emerged from the pins. At fledging nestlings exhibited a female-like colouration.
Life history traits in two Drosophila species differently affected by microbiota diversity under lead exposure
<p><em>We investigated the influence of population origin and heavy metal exposure to the diversity of microbiota in two species, Drosophila melanogaster and Drosophila subobscura grown in laboratory on lead (II) acetate (Pb(CH3COO)<sub>2</sub>) saturated substrate. The composition of microbiota in larvae and adults was determined by sequencing (NGS) of the V3-V4 variable regions of the 16S rRNA gene.</em></p>
Physical and biological constraints on the capacity for life-history expression of anadromous salmonids: an Eel River, California, case study
Recovery of anadromous salmonid populations is complicated by the fact that these fish have complex life-histories. Habitat valuation and capacity methods need to account for spatiotemporal variability in temperature, geomorphic features, and a species' thermal sensitivity mediated by biological interactions. We examined this interplay in a case study of steelhead trout (<i>Oncorhynchus mykiss</i>) and Chinook Salmon (<i>O. tshawytscha</i>) in California's Eel River watershed. We estimated habitat suitability and fish capacity for each salmonid run and freshwater life stage during average, cool, and warm years in each of the watershed's subbasins, including a high-elevation subbasin upstream of an impassable dam. Our estimates varied depending on whether we accounted for exposure to the Sacramento pikeminnow (<i>Ptychocheilus grandis</i>), an introduced predator/competitor. Our results indicate that the dammed subbasin could provide an important cool-water refuge during warm years and from pikeminnow, potentially improving the productivity and resilience of multiple anadromous salmonid populations. Our approach can be applied in any setting where spatially explicit habitat metrics can be estimated and population specific and life-stage specific habitat criteria can be specified.
