Fig. 1. Conceptual view of the expected influence of the new littoral zones with recoupled habitats on primary producers, macroinvertebrate primary consumers and higher trophic levels in Lake Markermeer, The Netherlands. Primary production in the original lake in the pelagic zone (left food web) is mainly driven by pelagic phytoplankton. In the new littoral zones (right food web), additional contributions of benthic (macrophytes and periphyton) and terrestrial (shore plants) primary producers are expected, forming a broader base of consumers and higher trophic levels in a more complex food web. Food web based on Jin (2021).

Fig. 2. (a) Lake Markermeer in the Netherlands with the sampling locations of isotope and community data indicated. The rectangle shows the location of the Marker Wadden in Lake Markermeer further detailed in panel b. (b) The Marker Wadden archipelago with the isotope and community data sampling locations. Turquoise shading indicates water depths shallower than 1.5 m. (c) Light availability in the form of Photosynthetically Active Radiation (PAR) at different water depths in lake Markermeer. The approximate shore / littoral and sheltered limnetic areas are indicated with turquoise and pink shading, respectively, which illustrates that PAR at the sediment surface in the 4 m deep open water is very low.

Creating shallow littoral habitats increased benthic production and carbon fluxes to pelagic zones, enhancing macroinvertebrate diversity in this restored lake. 🐟

Fig. 1. Overview over the day and night light settings of the five treatment groups. All groups had the same settings during the day, starting with approximately 80 lx at 7 am and an increase every 15 min until 8 am (steps: 80.10 ± 3.40 lx, 161.35 ± 7.21 lx, 239.90 ± 11.50 lx, 316.65 ± 13.32 lx), followed by a daylight phase (392.41 ± 19.61 lx) and a step-wise decrease from 10 – 11 pm following the same levels as from 7 – 8 am in reversed order. During the night, the illuminance was < 0.01 lx in the dark group (D), while the other groups experienced artificial light a night of different durations (P = part-night, C = continuous) and intensities (L = low, H = high), with the following illuminances: LP 5.20 ± 0.29 lx (at 11 pm – 2 am and 5 – 7 am), HP 49.00 ± 2.53 lx (11 pm – 2 am, 5 – 7 am), LC 5.20 ± 0.29 lx during the whole night, HC 49.00 ± 2.53 lx, whole night. Illuminance values are means ± SD taken from n = 17–20 measurements at the height of the Petri dishes containing the insects.

Fig. 1. The relationship between mean shoot length per grass species to species richness of the endophytic insects found in these shoots. A The number of herbivore species, B the sum of herbivore and parasitoid species. The five points indicating no species at all indicate that no one insect species has been reared from the five annual grass species studied, despite intensive shoot sampling (see Table 1). The inquilines of P. australis are included (see Table 2, see also Fig. S2A and S2B for regressions without inquilines). Regression lines were fitted to the species richness found in the ten perennial grass species.

Fig. 3. Percentage of reads attributed to carabid, prey and other for Nebria salina and Poecilus cupreus for samples from 2013 to 2019 and 2021. Colors distinguish between (a) prey reads (green), (b) carabid reads (blue) and (c) other reads (contaminants and not assigned – orange). Proportions are given as percentages of the total number per sample (after filtering the singletons).

The slope of the red line shows the shift in the onset of flowering as a function of temperature over the spatial gradient and the slope of the blue line shows the shift over the temporal gradient in Vienna. The gray area represents the 95 % confidence interval for both linear regressions, overlapping across the entire possible range. The linear regressions run nearly parallel to each other, illustrating the similarity between both methods. The dots combine mean temperature (x-axis) and flowering time (y-axis) within a year. The boxes represent the temperature ranges of the respective gardens and years.

🌸 New #BAAE article: Flowering shifts response to temperature.

Early-flowering species advance ~7 days per 1°C increase & space-for-time substitutions work well for general patterns but species-specific caution is needed.

Fig. 1. Estimated probability of fruit set for Pink Lady apples across different pollination treatments. Points represent model-predicted posterior means (±95% credible intervals). “Control” refers to open-pollinated flowers exposed to natural pollination, “Emasculation” to flowers with anthers removed to prevent self-pollen deposition, “Self-pollination” to hand-pollinated flowers using pollen from the same cultivar, and “Spontaneous” to flowers bagged throughout anthesis to test autonomous self-pollination. The other treatments represent the cultivar used to hand-pollinate the flowers. Fruit set was modelled as a binary response (1 = fruit set, 0 = no fruit set).

Fig. 2. Fruit weight and seed quality of Pink Lady apples. (A) Estimated fruit weight (g) and (B) estimated proportion of well-formed seeds for fruits that developed following different pollen-donor treatments: Control (open pollination), or hand-pollination with pollen from Fuji, Royal Gala, Granny Smith, or Kanzi. Dots represent individual fruit/seed measurements, while larger filled circles and error bars show model-predicted means ± 95% credible intervals from Bayesian mixed-effects models.

🍎🐝 New BAAE article:

In apples, pollen donor identity strongly affects fruit set, weight & seed quality. Choosing high-performing donors (beyond basic compatibility) can boost orchard productivity and fruit quality.

Fig. 1. Conceptual diagram of the relationships among the social-ecological dimensions of urban soundscapes. Urban soundscape characteristics likely are influenced by urban green space vegetation structure, which in turn influences biodiversity. Furthermore, urban soundscapes relate to dimensions of acoustic comfort and human wellbeing (restoration). Key for urban planning is to identify places of high biodiversity, acoustic comfort and restoration with positive effects on human wellbeing that can be equitably promoted in planning and sound-based policies.
