Stomach content, biomass, abundance and body score of long-tailed ducks (Clangula hyemalis) from south-eastern Baltic Sea

The long-tailed duck (Clangula hyemalis) is a vulnerable and declining species wintering in the Baltic Sea. The introduction of the invasive fish, the round goby (Neogobius melanostomus), dramatically impacted the benthic macrofauna in hard-bottom, while no significant changes occurred in soft-bottom benthic macrofauna. Therefore, we aimed to assess the extent to which the diet of long-tailed duck changed in two different bottom types. We analysed the stomach content of 251 long-tailed ducks bycaught in gillnets from 2016 to 2020 in hard- and soft-bottom habitats and compared these results with those published by Žydelis and Ruškyte (2005). The results show that the long-tailed duck experienced a change in diet in hard-bottom habitats, shifting from the blue mussel to Hediste diversicolor, barnacles and fish. In soft-bottom habitats, their diet remained similar over time and was based on H. diversicolor, a few bivalve species and Saduria entomon. There was no evidence of significant differences in diet neither between sex nor age. Despite the above-mentioned changes in diet, the average body condition of the species did not change neither over time nor between habitats. This confirms that long-tailed ducks have high feeding flexibility and quick species response to changes in prey availability, as they are capable of shifting their diet to new prey.

Biological experimental raw data from: The Incubascope : A simple, compact and large field of view microscope for long-term

Optical imaging has rapidly evolved in the last decades. Sophisticated microscopes allowing optical sectioning for 3D imaging or sub-diffraction resolution are available. Due to price and maintenance issues, these microscopes are often shared between users in facilities. Consequently, long term access is often prohibited and does not allow to monitor slowly evolving biological systems or to validate new models like organoids. Preliminary coarse long-term data that do not require do acquisition of terabytes of high-resolution images are important as a first step. By contrast with expansive all-in-one commercialized stations standard microscopes equipped with incubator stages offer a more cost-effective solution despite imperfect long run atmosphere and temperature control. Here, we present the Incubascope, a custom-made compact microscope that fits into a table-top incubator. It is cheap and simple to implement user-friendly and yet provides high imaging performances. The system has a field of view of 5.5×8 mm2, a 3 µm resolution, a 10 frames/second acquisition rate, and is controlled with a Python-based graphical interface. We exemplify the capabilities of the Incubascope on biological applications such as the hatching of Artemia salina eggs, the growth of the slime mold Physarum polycephalum and of encapsulated spheroids of mammalian cells.

Data from: Harvest and density-dependent predation drive long-term population decline in a northern ungulate

The relative effect of top-down versus bottom-up forces in regulating and limiting wildlife populations is an important theme in ecology. Untangling these effects is critical for a basic understanding of trophic dynamics and effective management. We examined the drivers of moose (Alces alces) population growth by integrating two independent sources of observations within a hierarchical Bayesian population model. This analysis used one of the largest existing spatiotemporal datasets on ungulate population dynamics globally. We documented a 20% population decline over the period examined. Moose population growth was negatively density-dependent. Although the mechanisms producing density-dependent suppression of population growth could not be determined, the relatively low densities at which moose populations were documented suggests it could be due primarily to density-dependent predation. Predation primarily limited population growth, except at low density, where it was regulating. Harvest appeared to be largely additive and contributed to population declines. Our results, highlight how population dynamics are context dependent and vary strongly across gradients in climate, forest type, and predator abundance. These results help clarify long-standing questions in population ecology and highlight the complex relationships between natural and human-caused mortality in driving ungulate population dynamics.

A systematic review of long-term avian studies on phenological changes of birds and their food

Many organisms reproduce in seasonal environments, where selection on timing of reproduction is particularly strong as consumers need to synchronize reproduction with the peaked occurrence of their food. When a consumer species changes its phenology at a slower rate than its resources, this may induce a trophic mismatch, i.e. offspring growing up after the peak in food availability, potentially leading to reductions in growth and survival. However, there is large variation in the degree of trophic mismatches as well as in its effects on reproductive output. Here, we explore the potential causes for variation in the strength of trophic mismatches in published studies of birds. Specifically, we ask whether the changes in the degree of mismatch that have occurred over time can be explained by a bird's (1) breeding latitude, (2) migration distance, and/or (3) life-history traits. In particular, the script used contains the following analyses: (I) using linear mixed effect models we test whether the rate of change in food phenology, bird phenology and their difference (i.e. the rate of change in asynchrony) differed significantly from zero, (II) using linear mixed effect models we test whether the rate of change in asynchrony between birds and their food could be explained by breeding latitude, migratory behaviour and/or species life-history traits (body mass, clutch size and incubation duration). We found that none of these three factors explains changes in the degree of mismatch over time. Nevertheless, food phenology did advance faster at more northerly latitudes, while shifts in bird phenology did not show a trend with latitude. We argue that the lack of support in our results is attributable to the large variation in the metrics used to describe timing of food availability.

Effects of long-term nitrogen addition on water use by Cunninghamia lanceolate in a subtropical plantation

The deposition of reactive nitrogen (N) has substantially increased in subtropical regions due to human activities. However, the effects of long-term N addition on the water-use efficiency of subtropical forests are poorly understood. Here, we conducted an 11-year experiment in a subtropical Cunninghamia lanceolate plantation with four N-addition levels: N0, N1, N2, and N3 (equivalent to 0, 6, 12, and 24 g of N m-2 yr-1, respectively). A thermal dissipation probe system was used to calculate sap flow and plant biomass carbon was assessed by field investigation. The whole-plant water use and water-use efficiency were estimated. In addition, the δ13C of tree rings was used to indicate the plant intrinsic water-use efficiency. The results showed that N3 significantly increased the annual sap flow velocity, especially in summer and winter. Annual water use, plant growth, and water-use efficiency did not significantly differ among the N treatments, but water use tended to be higher in N3 than in N0. Furthermore, the reduction of δ13C between the pre-N treatment period and the post-N treatment period was 3.02%, 3.26%, 3.58%, and 5.28% for N0, N1, N2 and N3, respectively, which supported the inference that N addition could enhance water use. We conclude that long-term addition of high levels (but not of low levels) of N increased whole-plant water use in C. lanceolate plantations. Our results indicate that N deposition accompanied by high temperature and drought events may negatively affect water balance in subtropical forests.
