“…The prey items are subsequently consumed mainly in the evening or the next morning, when temperatures are lower and insects are no longer or not yet very active (Hernandez 1995, Golawski et al 2020. The fact that limited access to food leads to a decrease in mean blood haemoglobin concentrations has been described in nestlings of many bird species (Minias 2015, Kali nski et al 2019, Lidman et al 2020, Zaremba et al 2021. Higher haemoglobin concentrations are a predictor of nestling survival from hatching to fledging (Kali nski et al 2015), whereas higher WBC counts suggest higher stress levels in nestlings, a situation unfavourable to the proper development of nestlings (Zaremba et al 2021).…”

“…Red blood cell (RBC) counts and haemoglobin concentrations are measures of the oxygen-carrying capacity of the blood (Smith et al 2000) and are used as indicators of the haematological condition of nestlings (Nadolski et al 2006, Ba nbura et al 2007). Haemoglobin concentrations have been found to increase with a high-quantity diet, suggesting that they may directly reflect the nutritional state of individuals (Ba nbura et al 2007, Lidman et al 2020. Low RBC counts can indicate illness (Campbell 1995, Artacho et al 2007 or anaemia, because erythropoiesis (RBC production) depends on nutritional status.…”

Storing prey in larders affects nestling haematological condition in the Red‐backed Shrike (Lanius collurio)

Many animals, including shrikes (Laniidae), are known to store food. This behaviour ensures food availability during inclement weather, for rearing nestlings or signalling territory quality. Unlike most other shrike species, which accumulate food before breeding, Red‐backed Shrikes Lanius collurio store food in larders, mainly during the nestling and fledgling periods. If this is an adaptive behaviour, variation in this behaviour should affect either or both the number and condition of nestlings, which may benefit from such larders. We assessed the haematological condition of Red‐backed Shrike nestlings in east‐central Poland in 2021 using a suite of blood parameters relating to sites where shrikes did or did not store food. Haemoglobin concentrations were positively correlated with larders, being significantly higher in nestlings of pairs that stored prey compared with those whose parents did not do so. White blood cell counts were lower in nestlings whose parents kept larders. Red blood cell counts and glucose concentrations in nestlings were not related to whether parents had larders. Food storage probably ensures a more constant access to food, which results in a superior haematological condition in nestlings.

“…Deposition traps (18 × 18 × 9 cm 3 squared plastic boxes), to collect aquatic emergent insects, were deployed for a period of 16 days in spring 2017 (May 31 to June 15). , Sets of three deposition traps were placed about 5 m from each other within 5 m from the shore at three locations per sampling site, resulting in nine traps per site (double at the lake since two sampling locations were there). In 2018, deposition traps were deployed during the entire early spring emergence (May 2 to July 3).…”

Emergent aquatic insects are important food subsidies to riparian food webs but can also transfer waterborne contaminants to the terrestrial environment. This study aimed to quantitatively assess this biodriven transfer for per- and polyfluoroalkyl substances (PFAS). Aquatic insect larvae, emergent aquatic insects, terrestrial consumers, sediment, and water were collected from a contaminated lake and stream and an uncontaminated pond, and analyzed for PFAS and stable isotopes of carbon and nitrogen. Top predators in this study were spiders, which showed the highest average ∑ 24 PFAS concentration of 1400 ± 80 ng g –1 dry weight (dw) at the lake and 630 ng g –1 dw at the stream. The transfer of PFAS from the lake to the riparian zone, via deposition of emergent aquatic insects, was 280 ng ∑ 24 PFAS m –2 d –1 in 2017 and only 23 ng ∑ 24 PFAS m –2 d –1 in 2018. Because of higher production of emergent aquatic insects, the lake had higher PFAS transfer and higher concentrations in terrestrial consumers compared to the stream, despite the stream having higher PFAS concentration in water and aquatic insect larvae. Our results indicate that biodriven transfer of PFAS from the aquatic systems and subsequent uptake in terrestrial food webs depend more on emergence amounts, i.e., aquatic prey availability, rather than on PFAS concentrations in water and aquatic prey.

Contamination of aquatic ecosystems can have cascading effects on terrestrial consumers by altering the availability and quality of aquatic insect prey. Comprehensive assessment of these indirect food‐web effects of contaminants on natural resources and their associated services necessitates using both ecological and economic tools. In the present study we present an aquatic‐terrestrial assessment tool (AT2), including ecological and economic decision trees, to aid practitioners and researchers in designing contaminant effect studies for linked aquatic‐terrestrial insect‐based food webs. The tool is tailored to address the development of legal claims by the US Department of the Interior's Natural Resource Damage Assessment and Restoration Program, which aims to restore natural resources injured by oil spills and hazardous substance releases into the environment. Such cases require establishing, through scientific inquiry, the existence of natural resource injury as well as the determination of the monetary or in‐kind project‐based damages required to restore this injury. However, this tool is also useful to researchers interested in questions involving the effects of contaminants on linked aquatic‐terrestrial food webs. Stylized cases exemplify how application of AT2 can help practitioners and researchers design studies when the contaminants present at a site are likely to lead to injury of terrestrial aerial insectivores through loss of aquatic insect prey and/or dietary contaminant exposure. Designing such studies with ecological endpoints and economic modeling inputs in mind will increase the relevance and cost‐effectiveness of studies, which can in turn improve the outcomes of cases and studies involving the ecological effects of contaminants on food webs.
