This study examines the risks of relying solely on images for biodiversity documentation. We conducted an experiment with 621 participants, revealing challenges in distinguishing artificial-intelligence-generated images. Trust is vital in biodiversity documentation, but eroded trust can hinder conservation. We call for improved communication, collaboration, and journal policies for data validation to preserve scientific credibility amidst technological advancements.

Modelling tools may provide a method of measuring pollination supply and promote the use of ecological intensification techniques among farmers and decision-makers. This study benchmarks different modelling approaches to provide clear guidance on which pollination supply models perform best at different spatial scales. These findings are an important step in bridging the gap between academia and stakeholders in modelling ecosystem service delivery under ecological intensification.

This study analyzes the diversity of benthic foraminifera at the range expansion front of the invasive species Amphistegina lobifera in Corfu (central Mediterranean). The species has been suggested to impact local diversity and community structures, and our results confirm these effects as soon as A. lobifera exceeds a specific abundance threshold (> 20 %). Nevertheless, we found that the study area reveals an overall high biodiversity that can be attributed to its unique location.

The abandonment of extensively managed mountainous meadows affects the diversity of both plants and associated pollinators. However, not much is known about the effects of abandonment on hoverflies which consitute an important pollinator group in grasslands. Our research suggests that extensive management is most beneficial in preserving hoverfly richness in mountainous grasslands.

We introduce the Alpine research platform Ödenwinkel to promote observational and experimental research on the emergence of multidiversity and ecosystem complexity. The Ödenwinkel platform will be available as a long-term ecological research site where researchers from various disciplines can contribute to the accumulation of knowledge on ecological successions and on how interactions between various taxonomic groups structure ecological complexity in this Alpine environment.

We studied the influence of plant diversity on recovery from stress. The blood pressure of stressed people decreased more strongly when they were looking at species-rich vegetation instead of bare ground or vegetation consisting of only a few species during relaxation. Our results indicate that species-rich vegetation may contribute to recovery from stress, which should be considered in landscape management and planning.

We studied the effect of abandonment of extensively managed semi-natural grasslands on indicators of ecosystem services (ES) and found both positive and negative effects. We also studied relationships between ESs and plant species richness and whether abandonment affect these relationships. For several ESs we observed positive relationships. However, the relationships differed often between the abandoned and managed grasslands because the relationships were less pronounced in the managed.

We used an original global approach to explore the potential relationship between PAs and the intentional movement of IPS based on climate change. Climate change developed the potential pathways for IPS in PAs, and the ability of natural dispersal encourages IPS to invade non-native habitats in the potential movement pathways in PAs. This study shows the importance of the development of global conservation planning for PAs and biological invasion.

We show areas for extending current protected areas and creating new ones for endangered sub-species of the Lynx lynx martinoi in the Albania–Macedonia–Kosovo and Montenegro–Albania–Kosovo cross-border areas. Our results highlight the importance international cooperation can have for lynx conservation. We used local knowledge on forests in the study area, our analytical skills, and our full interest in the lynx conservation. We did this study working remotely.

The relations between environmental gradients and traditional diversity indices (taxonomic richness, diversity and evenness) of benthic macroinvertebrate communities in the lotic systems of northern Italy were analyzed. Redundancy analysis (RDA) was used to describe the response of taxa to environmental gradients. Diversity indices were analyzed using generalized linear models (GLMs) with explanatory variables the first two major RDA axes.

The transition from a mobile hunter-gatherer lifestyle to one of settled agriculture is arguably the most fundamental change in the development of human society (Lev-Yadun et al., 2000). The establishment of agricultural economies, emerging initially in the Fertile Crescent of the Near East (Nesbitt, 2002), required the domestication of crops; ancient plant remains recovered from early
farming sites provide direct evidence for this process of domestication.

The effects of tree diversity on the photosynthetic efficiency of tree species were assessed on six European mature forests (distributed along a latitudinal gradient) and in forest stands planted ad hoc with different levels of tree-species richness. The behaviour of Picea abies (spruce) was compared at the different sites. Site-specific responses were detected in relation to the age of the stands and their developmental stage.

Clear-fellings to introduce heterogeneity can be an important component of a forest management plan. However, it is misleading to compare clear-fellings to protected areas dominated by old-growth forests using a simplistic measure of biodiversity and without a landscape perspective. To minimize the well-documented role of protected areas can have adverse effects on forested landscapes, primary forest remnants, and taxa that rely on forest structural elements characteristic of old-growth forests.

Short summary
This study determines the diversity of pollen morphotypes of Atriplex halimus (Amaranthaceae) along a large-scale climatic gradient. Occurrences of 10 pollen grain shapes were quantified at seven climates across a humid-to-hyperarid gradient. We discuss how the evolutionary effects of climate gradients on pollen morphology and variability in dryland induce a high level of specialization to maximize trade-offs between adaptation to severe ecological conditions and pollination efficiency.
