Towards a multisensor station for automated biodiversity monitoring

Basic and Applied Ecology, Journal Year: 2022, Volume and Issue: 59, P. 105 - 138

Published: Jan. 7, 2022

Rapid changes of the biosphere observed in recent years are caused by both small and large scale drivers, like shifts temperature, transformations land-use, or energy budget systems. While latter processes easily quantifiable, documentation loss biodiversity community structure is more difficult. Changes organismal abundance diversity barely documented. Censuses species usually fragmentary inferred often spatially, temporally ecologically unsatisfactory simple lists for individual study sites. Thus, detrimental global their drivers remain unrevealed. A major impediment to monitoring lack human taxonomic expertise that implicitly required large-scale fine-grained assessments. Another amount personnel associated costs needed cover scales, inaccessibility remote but nonetheless affected areas. To overcome these limitations we propose a network Automated Multisensor stations Monitoring Diversity (AMMODs) pave way new generation assessment centers. This combines cutting-edge technologies with informatics expert systems conserve knowledge. Each AMMOD station autonomous samplers insects, pollen spores, audio recorders vocalizing animals, sensors volatile organic compounds emitted plants (pVOCs) camera traps mammals invertebrates. AMMODs largely self-containing have ability pre-process data (e.g. noise filtering) prior transmission receiver storage, integration analyses. Installation on sites difficult access require sophisticated challenging system design optimum balance between power requirements, bandwidth transmission, service, operation under all environmental conditions years. An important prerequisite automated identification databases DNA barcodes, animal sounds, pVOCs, images used as training identification. thus become key component advance field research policy delivering at an unprecedented spatial temporal resolution.

We need to talk about nonprobability samples

Trends in Ecology & Evolution, Journal Year: 2023, Volume and Issue: 38(6), P. 521 - 531

Published: Feb. 10, 2023

In most circumstances, probability sampling is the only way to ensure unbiased inference about population quantities where a complete census not possible. As we enter era of 'big data', however, nonprobability samples, whose mechanisms are unknown, undergoing renaissance. We explain why use samples can lead spurious conclusions, and seemingly large be (effectively) very small. also review some recent controversies surrounding in biodiversity monitoring. These points notwithstanding, argue that useful, provided their limitations assessed, mitigated possible clearly communicated. Ecologists learn much from other disciplines on each these fronts.

Insect decline in forests depends on species’ traits and may be mitigated by management

Communications Biology, Journal Year: 2023, Volume and Issue: 6(1)

Published: April 4, 2023

Abstract Insects are declining, but the underlying drivers and differences in responses between species still largely unclear. Despite importance of forests, insect trends therein have received little attention. Using 10 years standardized data (120,996 individuals; 1,805 species) from 140 sites Germany, we show that declines occurred most across trophic groups. In particular, (quantified as correlation year respective community response) were more consistent with many non-native trees or a large amount timber harvested before onset sampling. Correlations at level depended on species’ life-history. Larger species, abundant higher declined most, while herbivores increased. This suggests potential shifts food webs possibly affecting ecosystem functioning. A targeted management, including promoting natural tree composition partially reduced harvesting, can contribute to mitigating declines.

City climate and landscape structure shape pollinators, nectar and transported pollen along a gradient of urbanization

Abstract Urbanization gradients influence both landscape and climate provide opportunity for understanding how plants pollinators respond to artificially driven environmental transitions, a relevant aspect the ecosystem service of pollination. Here, we investigated several aspects pollination along an urbanization gradient in climate. We quantified wild hoverfly bee abundances with trapping, standing crop nectar spectrophotometer, pollen transported by flower visitors DNA metabarcoding, 40 independent sites from semi‐natural built‐up areas Northern Italy. Direct indirect effects were fitted considering variables. Linear nonlinear relationships detected gradient. Pollinator increased quadratically peaked at 22% impervious cover 81% growth, they decreased green‐patch distance 37% urban park largeness 60%. This indicates that are more abundant intermediate levels urbanization. Climatically, diminished up 46% low spring–summer temperature seasonality: likely posing thermic stress. Furthermore, sugar mass available 61% 79% precipitations, indicating city nectars less consumed or flowers productive. species richness 32% highly urbanized areas, contained high incidence exotic plants, hinting anthropized, simplified plant communities.

Suburban landscapes demonstrated highest presence. In core, nectary association while collected small number mainly exotic. These findings highlight strong on showing cities heterogenous realities. Patterns this study will serve as basis pollinator‐friendly planning, mitigation management landscapes.

Reliable assessment measures are crucial for tracking changes in biodiversity and evaluating the state of biodiversity. Two main drivers habitat heterogeneity resource amount. These used as proxies but assessing both is costly, limiting their practical use. To test which best predicts number abundance sessile species conservation concern (including macrofungi, lichens, bryophytes, vascular plants), we assessed forest stand using a method developed Sweden ('Habitat Heterogeneity Score HHS'), quantified amount quality ecologically important structural variables (deadwood volume, basal area living trees, proportion broadleaved age oldest tree stand).

Understanding and reversing biodiversity decline in the Anthropocene requires robust data on species taxonomic identity, distribution, ecology, population trends. Data deficits hinder assessments conservation, despite major advances over past few decades, our understanding of bee diversity, distribution Europe is still hampered by such shortfalls. Using a unique digital dataset wild occurrence we identify seven critical shortfalls which are an absence knowledge geographic distributions, (functional) trait variation, dynamics, evolutionary relationships, biotic interactions, tolerance to abiotic conditions. We describe "BeeFall," interactive online Shiny app tool, visualizes these highlights missing data. also define new impediment, Keartonian Impediment, addresses high-quality situ photos illustrations with diagnostic characteristics directly affects outlined Shortfalls highly correlated at both provincial national scales, identifying key areas where gaps can be filled.

Results Southern eastern Europe suffer from largest gaps availability while northern western benefit better historical coverage. Our models show that higher is hosted xeric, warm areas, as highlighted by clear latitudinal gradient. However, predicted be more homogenous across than diversity, suggesting policies strategies targeted protect richness may differ those targeting greater diversity.

Forest Ecosystems, Journal Year: 2022, Volume and Issue: 9, P. 100056 - 100056

Published: Jan. 1, 2022

Retention forestry is a management strategy aiming to mitigate biodiversity loss by retaining structural elements such as dead trees that would otherwise be removed. Here we analyze the biomass, diversity and abundance among forest beetles collected using window traps on 128 1-ha sites reflecting gradients in amount of southwestern Germany. We found beetle biomass increased with mean diameter at breast height (a measure tree size), decreased stand complexity. Biomass individual feeding guilds responded differently elements, namely lying deadwood, understory complexity, basal area Beetle family effective number layers, i.e. 1-m strata occupied vegetation assessed via terrestrial laser scanning. Abundance only elevation share deciduous trees. Community composition terms was structured similar guilds, addition deadwood.
