title: Die Schlei: Katalog der submarinen Funde und der Uferfunde. A SQLite database from the original catalogue.

description: Spatialite database (SQL), SQL statements and documentation. The data is taken from the catalogue provided and analysed by Oliver Nakoinz. O. Nakoinz, Die Schlei: Katalog der submarinen Funde und der Uferfunde. Festgabe Joachim Reichstein. Offa 59/60, 2003/04, 2005, 167–218. The Offa journal is being retro-digitised and the publication will also be available digitally in the future. The current status is 2011. The data was collected, reorganized, reviewd and sturctured in this database in a course on computational archaeology held at Christian-Albrechts-University at Kiel (CAU Kiel) in the winter term 2024/25. The retrieval of data was the container to introduce text based data processing using regular expressions, basic concepts of a relational database, SQL, Markdown and the interoperability between some open software (Notepad++, DB Browser (SQLite) and QGIS). The overarching goal was to create an awareness of data structures in the context of reusable data and reproducible research.

title: Data from: Cranial anatomy of the mekosuchine crocodylian Trilophosuchus rackhami Willis, 1993

description: One of the best-preserved crocodylian fossil specimens from the Cenozoic
 of Australia is the holotype of the mekosuchine Trilophosuchus rackhami,
 from the middle Miocene (13.56 ± 0.67 Ma) Ringtail Site at Riversleigh,
 northwestern Queensland. Although lacking most of the snout, the holotype
 skull of T. rackhami (QMF16856) has an exceptionally well-preserved
 cranium. Micro-CT scanning of the holotype has allowed for all the
 preserved cranial bones to be digitally disarticulated, facilitating an
 unprecedented insight into the cranial anatomy of not just T. rackhami,
 but any mekosuchine. Trilophosuchus rackhami was a small-bodied
 crocodylian and one of the most morphologically distinct mekosuchines,
 characterized by a unique combination of cranial characteristics several
 of which are exclusive to the species. Fossil material that is
 definitively referrable to the species T. rackhami is currently known
 solely from the middle Miocene Ringtail Site. However, an isolated
 parietal from Hiatus Site at Riversleigh demonstrates that Trilophosuchus
 also occurred during the late Oligocene (~25 Ma), extending the range of
 the genus by more than ten million years. The new description of T.
 rackhami also allowed for a reevaluation of its phylogenetic
 relationships. Our results reaffirm the placement of T. rackhami as a
 member of Mekosuchinae within the subclade Mekosuchini. In all analyses,
 Mekosuchinae was consistently found to be monophyletic and part of the
 larger crocodylian clade Longirostres. However, the assignment of
 Mekosuchinae as a subset of Crocodylidae is brought into question,
 suggesting that the status of Mekosuchinae as a subfamily should be
 reconsidered.

title: Widespread controls of leaf nutrient resorption by nutrient limitation and stoichiometry

description: Leaf nutrient resorption is a key process in nutrient cycles, but
 fundamental knowledge regarding its control mechanisms remains limited.
 Among the three proposed basic control mechanisms on leaf nutrient
 resorption, namely nutrient concentration control, nutrient limitation
 control, and stoichiometry control, only the first has been demonstrated
 to exist globally, while the latter two have not been systematically
 evaluated. Here, we conducted a global data synthesis to explore nutrient
 limitation and stoichiometry control on leaf resorption of carbon,
 nitrogen, phosphorus, sulfur, potassium, calcium, and magnesium, based on
 3,395 data points from 109 peer-reviewed studies.  Results showed
 that the nutrient limitation control existed globally, but was only
 applicable for the resorption of nitrogen, phosphorus, and potassium. The
 stoichiometry control existed globally for carbon and all studied
 nutrients, and coexisted with nutrient limitation control. Conifers’
 resorption relied primarily on stoichiometry control rather than nutrient
 limitation control. Nutrient limitation control was stronger in evergreen
 angiosperms than in deciduous angiosperms. Our findings support the
 ubiquity of both nutrient limitation and stoichiometry in controlling leaf
 resorption for multiple nutrients, such that these controls should be
 considered in Earth system models to better predict biogeochemical cycles
 in terrestrial ecosystems.

title: Depleted cultural richness of an avian vocal mimic in fragmented habitat

description: Aim: Conservation has recently shifted to include behavioural or cultural
 diversity, adding substantial value to conservation efforts. Habitat loss
 and fragmentation can deplete diversity in learnt behaviours such as bird
 song by reducing the availability of song tutors, yet these impacts are
 poorly understood. Vocal mimicry may be particularly sensitive to habitat
 loss and fragmentation through the resulting reduction in both
 heterospecific models and conspecific tutors. Here we examine the
 relationship between habitat availability and mimetic repertoire size and
 composition in male Albert’s lyrebirds (Menura alberti), a near-threatened
 species renowned for its remarkable mimetic abilities. Location: Eastern
 Australia Methods: We calculated repertoire size and composition from
 recordings of male Albert’s lyrebirds from throughout the species’ range.
 We estimated patch size and local habitat availability using a species
 distribution model and remotely sensed vegetation types. We assessed the
 local model species assemblage through species distribution models and
 automated acoustic detectors. Results: Individual males in smaller habitat
 patches, or in areas with a lower proportion of suitable habitat, mimicked
 fewer model species and fewer vocalisation types, though they mimicked
 comparatively more vocalisations from each model species than individuals
 in larger patches or with more intact habitat. All model species were
 likely to occur in most study sites, suggesting that repertoires are not
 driven by the availability of model species. Main conclusions: Our results
 suggest that mimetic repertoire sizes are influenced by habitat
 availability through the number of lyrebird tutors. Further, individuals
 in disturbed habitat may partially compensate for mimicking fewer species
 by mimicking more vocalisations from each species. This study supports the
 hypothesis that cultural diversity may be impoverished by habitat loss and
 fragmentation in a similar way to genetic diversity. Variation in song
 diversity may therefore signal population health and highlight populations
 in particular need of conservation action.

title: Collective foraging: Experimentally-increased competition decreases group performance exploiting a permanent resource

description: Foraging collectively offers advantages, such as access to social
 information on food locations, but it may also intensify competition for
 local resources. Social information may be most advantageous during
 ecologically challenging conditions, when food sources are scarce or
 unpredictable, which predicts more collective foraging during such
 conditions. Alternatively, higher within-group competition when resources
 are scarce might destabilize social groups and reduce collective foraging.
 To evaluate these effects, we experimentally decreased the number and
 predictability of food sources (feeders with ad libitum seeds) available
 to wild-caught common waxbills (Estrilda astrild) living in a large
 open-air mesocosm. Compared to control periods, in the treatment with few
 food sources competitive aggressiveness at feeders increased, the social
 network became more fragmented, with on average weaker associations
 between individuals, and foraging groups became smaller. Foraging groups
 also spent less time per visit to the feeding area, individuals spent less
 time at the feeders per group visit and had to make more visits to the
 feeding area per day, all of which indicate less efficient exploitation of
 the food sources. These effects were also observed when the number of
 feeders changed unpredictably across days. Even though the collective
 behaviour of waxbills appeared to exacerbate, rather than mitigate, the
 ecological challenges of reduced or unpredictable food sources, we suggest
 that, in nature, this increased aggressiveness and fragmentation of the
 social network may function adaptively as an early trigger to explore
 alternative foraging locations before local food sources are severely
 depleted.

title: An Experimental Test of Lanchester’s Models of Combat in the Neotropical Termite Nasutitermes corniger (Blattodea: Termitidae)

description: Lanchester’s models of combat have been invoked to explain the mechanics
 of group fighting in social animals. Specifically, Lanchester’s square law
 posits that the fighting ability of the group is proportional to the
 square of the number of combatants. Although used to explain a variety of
 ecological phenomena, the models have not been thoroughly
 tested. We tested the Lanchester models using group battles
 between colonies of the termite Nasutitermes corniger. Our main goals were
 to determine if mortality rates fit the Lanchester models, and if so,
 whether the behavioural mechanisms underlying a group’s success match
 those used in deriving the model. We initiated battles between pairs of
 colonies with different ratios of fighters and recorded deaths over time.
 We found that the numerically larger army has an advantage, but that the
 advantage is not as pronounced as predicted by Lanchester’s square law. We
 also video-recorded battles to analyse individual behaviour, which did not
 support the mechanisms invoked by Lanchester. Instead, the killing power
 of an individual is increased by the presence of nestmates, giving the
 larger group a disproportionate advantage. Although the behavioural
 mechanisms leading to the advantage may differ, our results still support
 some of the proposed ecological phenomena.
description: Intraspecific battles were
 performed using the termite <em>Nasutitermes corniger</em>.
 <em>N. corniger</em> is abundant at the La Selva field station
 in Costa Rica, which is situated in a lowland tropical rainforest
 (10.430623, -84.006971). This species builds arboreal nests that can house
 thousands to millions of termites that are highly territorial
 (Adams & Levings,
 1987; Thorne, 1980; Thorne & Haverty, 1980). Consequently, intraspecific battles between
 colonies can be observed naturally in open air (Levings & Adams,
 1984). Termites from two
 castes were collected: workers and soldiers. The soldiers shoot a
 gummy-like substance from their cone-shaped heads, which is more effective
 against ant and vertebrate predators than other termites
 (Thorne,
 1982). Thus, we focused on
 workers, which use their mandibles as both a defensive and offensive
 weapon. For trials, workers were picked arbitrarily and
 their abdomens were painted using Testors paint to identify their colony
 (N=6) of origin. Initial ratios of 40:10, 25:25, and 10:40 workers were
 used for each colony pairing and each ratio was replicated three times per
 colony pair. Each colony was only paired with one other, resulting in 27
 battles. Battles were staged in 60 x 15 mm petri dishes. As a control,
 fifty painted and fifty unpainted workers from each colony were placed in
 separate petri dishes for 12 hours, with deaths counted every hour (deaths
 ranged from 0 to 2 total).

title: Data, analytical, and plotting codes needed to reproduce meta-analyses on within-season divorce in birds

description: This data package contains data (effect sizes and other variables) and
 analytical codes needed to reproduce three meta-analyses on within-season
 divorce and breeding success in socially monogamous birds (Culina
 & Brouwer: No evidence of immediate fitness benefits of
 within-season divorce in monogamous birds. 2022. Biology Letters.) It also
 contains codes to reproduce Figures from the main text and from the
 Supplement. Readme file and Licence are provided too.
description: Datasets were collected via systematic review. A study was
 eligible if it: (1) was conducted on a predominantly
 socially monogamous species with bi-parental care. We determent the level
 of social monogamy based on information on the species (or a population)
 as provided in the corresponding study retrieved by our systematic
 review; (2) either compared breeding success between
 (A) divorced and widowed, divorced and faithful, or widowed and faithful
 pairs/individuals in one of the following: (i) the first breeding attempt
 of the season, (ii) the second breeding attempt of the season, (iii) the
 change of breeding success between the two attempts; or (B) breeding
 success (change in breeding success between two attempts, or breeding
 success in the second attempt) between divorced females and males, or
 between widowed females and males. Systematic
 literature search for studies published in English was conducted via 15
 online databases/search platforms in March 2022. Resuts reproted in these
 studies were used to calculate effect sizes. Please see more detail in

title: Data from: The intraspecific relationship between wood density, vessel diameter and other traits across environmental gradients

description: This data is about several traits measured on branches of 3 wide-niche
 breadth tree species--Embothrium coccineum (Proteaceae, Nothofagus
 antarctica (Nothofagaceae) and N. pumilio--growing across environmental
 gradients in southern Chile. The traits involve leaf, wood anatomy,
 including wood density, growth, carbon reserves and wood isotopes.
description: Branches were collected in the field and processed in the
 laboratory where branch sections were extracted to determine several
 traits. One portion was used for wood density, another portion was grinded
 for chemical analysis (non-structural carbohydrates and isotopes), another
 portion was used to make cuts for wood anatomy examination.

title: Data from: Different taxonomic and functional indices complement the understanding of herb-layer community assembly patterns in a southern-limit temperate forest

description: The efficient conservation of vulnerable ecosystems in the face of global
 change requires a complete understanding of how plant communities respond
 to various environmental factors. We aim to demonstrate that a combined
 use of different approaches, traits, and indices representing each of the
 taxonomic and functional characteristics of plant communities will give
 complementary information on the factors driving vegetation assembly
 patterns. We analyzed variation across an environmental gradient in
 taxonomic and functional composition, richness, and diversity of the
 herb-layer of a temperate beech-oak forest that was located in northern
 Spain. We measured species cover and four functional traits: leaf dry
 matter content (LDMC), specific leaf area (SLA), leaf size, and plant
 height. We found that light is the most limiting resource influencing
 herb-layer vegetation. Taxonomic changes in richness are followed by
 equivalent functional changes in the diversity of leaf size but by
 opposite responses in the richness of SLA. Each functional index is
 related to different environmental factors even within a single trait
 (particularly for LDMC and leaf size). To conclude, each characteristic of
 a plant community is influenced by different and even contrasting factors
 or processes. Combining different approaches, traits, and indices
 simultaneously will help us understand how plant communities work.

title: Mating traits and fitness components in two breeding designs in Drosophila serrata

description: Misalignment between male and female interests over mating creates
 inter-locus sexual conflict that is known to drive the coevolution of
 reproductive traits. Males and females also share the majority of their
 genome, which may cause these traits to genetically covary between the
 sexes and experience intra-locus sexual conflict where beneficial alleles
 in one sex are costly when expressed in the other. Traits expressed during
 mating may uniquely be subject to both intra- and interlocus sexual
 conflict. Here, we use a biologically repeated quantitative genetic
 experiment to test whether intra-locus sexual conflict is operating on
 mating latency, and copulation duration in the polyandrous fruit-fly
 Drosophila serrata. Mating latency and copulation duration were both
 heritable in males but not in females, and within sex and across-sex
 genetic correlations among the traits were all small. We found no
 significant genetic covariance between any measured mating behaviours and
 fitness components, nor between male and female fitness, suggesting that
 these traits are not under strong selection. Our study, therefore, finds
 little evidence of ongoing intra-locus sexual conflict over these traits.
 One explanation for our result is that these mating traits have
 historically been under strong selection, which has exhausted their
 genetic variation, making it difficult to detect selection in these
 populations. Keywords: mating latency, copulation duration, quantitative
 genetics, sexual conflict, Drosophila serrata, multivariate analyses,
 cuticula.

title: Female reproductive fluid increases the opportunities for post-mating sexual selection by prolonging egg fertilization window

description: Female reproductive fluid, the fluid that surrounds the eggs, has
 attracted increasing attention for its role in fertilization and
 post-mating sexual selection through its effects on sperm traits.
 Surprisingly, however, only a few studies have investigated the effects of
 female reproductive fluid on the eggs. Yet, these effects might offer
 great potential to affect fertilization dynamics by, for example,
 increasing the opportunities for post-mating sexual selection. Here, we
 determined whether, by extending the egg fertilization window
 (time available for egg fertilization), the female reproductive
 fluid could also increase the opportunities for multiple paternity. Using
 the Zebrafish Danio rerio we first tested the prediction that
 female reproductive fluid increases the egg fertilization window,
 and then, using a split-brood design with sperm of two males added at
 different times after eggs activation, we tested whether the
 degree of multiple paternity varies in presence or absence of
 female reproductive fluid. Our results reveal the potential of the female
 reproductive fluid to increase multiple paternity throughout its effects
 on the egg fertilization window thus broadening our knowledge of
 the mechanisms females in externally fertilizing species affect
 post-mating sexual selection.

title: Data from: Passive acoustic monitoring provides reliable under-estimates of population size and longevity in wild Savannah Sparrows

description: Many breeding birds produce conspicuous sounds, providing tremendous
 opportunities to study free-living birds through acoustic recordings.
 Traditional methods for studying population size and demographic features
 depend on labour-intensive field research. Passive acoustic monitoring
 provides an alternative method for quantifying population size and
 demographic parameters, but this approach requires careful validation. To
 determine the accuracy of passive acoustic monitoring for estimating
 population size and demographic parameters, we used autonomous recorders
 to sample an island-living population of Savannah Sparrows (Passerculus
 sandwichensis) over a six-year period. Using the individually distinctive
 songs of males, we estimated male population size as the number of unique
 songs detected in the recordings. We analyzed songs across six years to
 estimate birth year, death year, and longevity. We then compared the
 estimates to field data in a blind analysis. Estimates of male population
 size through passive acoustic monitoring were, on average, 72% of the true
 male population size, with higher accuracy in lower-density years.
 Estimates of demographic rates were lower than true values by 29% for
 birth year, 23% for death year, and 29% for longevity. This is the first
 investigation to estimate longevity with passive acoustic monitoring, and
 adds to a growing number of studies that have used passive acoustic
 monitoring to estimate population size. Although passive acoustic
 monitoring under-estimated true population parametersfeatures, likely due
 to the high similarity among many male songs, our findings suggest that
 autonomous recorders can provide reliable estimates of population size and
 demographic characteristicslongevity in a wild songbird.

 manuscript "Passive acoustic monitoring provides reliable
 under-estimates of population size and longevity in wild Savannah
 Sparrows."

title: Phylogenetic relatedness of food plants reveals highest insect herbivore specialization at intermediate temperatures along a broad climatic gradient

description: Phytophagous insects differ in their degree of specialisation, biased by
 resource availability. The composition and richness of herbivore and plant
 assemblages change along climatic gradients, but knowledge about
 associated shifts in specialisation is scarce and lacks controlling for
 abundance and phylogeny of interaction partners. Thus, we aimed to test
 whether the specialisation of herbivores in insect- plant – interaction
 networks decreases towards cold habitats as predicted by the ‘altitude
 niche-breadth hypothesis’ to forecast possible consequences of interaction
 rewiring under climate change. We used a non-invasive, standardized
 metabarcoding approach to reconstruct dietary relationships of Orthoptera
 species as a major insect herbivore taxon along a broad temperature
 gradient (~12 °C) in southern Germany. Based on orthopteran surveys,
 direct feeding observations in field, collection of faecal pellets from
 &gt; 3,000 individuals of 54 species, and parallel vegetation surveys
 on 41 grassland sites, we quantified plant resource availability and its
 use by herbivores. Faecal samples were pooled for each species per site.
