Introduction The standardization of sampling protocols is imperative for robustly studying any taxonomic group. Replicable methods allow the comparison data between different spatial and temporal studies. In case dung beetles, one best-studied indicator groups in analyses environmental disturbance, a wide range collection methodologies are used, from basic pitfall traps to more complex or complementary such as mini-Winkler extractor. Also, types attractive baits, effort, durations, designs used beetle Variations methodological approaches particularly noted Neotropics, which may be related vast number biological strategies behavior beetles that inhabit this region. A lack unification Neotropical region makes cross-sectional analysis information impossible. Methods We performed compilation analytical review existing literature discussing most methodologies, their advantages disadvantages, specific cases particular models efficient. Results Pitfall baited with human excrement common method, but there variations structure trap. effect generated by flight interception traps, light direct collections, within microhabitats, exciting potential finding new species. Some extractor, fogging, very infrequently used. Discussion There was inclusion variation among Therefore, it necessary consider broader windows, include scales, seasons, years. Finally, we propose standard protocol depending on each objective, including methodology obtaining complete local inventories.

Abstract Because of continuing degradation or deforestation in areas undisturbed primary forest, there is a need to study the relative merit strategies that mitigate their impacts on biodiversity and associated ecological functionality. Here, we provide global synthesis forest using 48 studies published peer‐reviewed journals use dung beetles as indicators given sensitivity anthropogenic disturbance relevance performing essential functions terrestrial ecosystems. We evaluated cover with (i.e. degraded forest) secondary forestry plantations restoration implementation) species richness, total abundance, biomass, functional groups' presence provided by beetles. Additionally, determined whether if beetle responses disturbances were geographically dependent. found lower diversity decrease all classes forest. However, effects less severe case compared complete natural regeneration development active planting indigenous trees. The Neotropical Oriental regions are particularly vulnerable, elevated rates its negative impact assemblages' functions. Synthesis applications . Our results show efforts for conservation remaining forests be prioritized, especially tropical latitudes. where not feasible, logging management programs may have potential role reducing Moreover, conclude despite effect implementation plantation restoration, they can useful partial recovery performed lacking any (undisturbed degraded) vegetation cover.

Dieback of managed spruce stands in western Germany promotes beetle diversity

Journal of Forestry Research, Год журнала: 2024, Номер 35(1)

Опубликована: Фев. 10, 2024

Abstract Biodiversity loss is a significant problem at global scale and may be amplified by climate change. In recent years, coniferous forests have had substantial dieback across Europe due to drought subsequent bark-beetle outbreaks. As many studies on the consequences of disturbance management focused natural stands, implications for managed spruce stands are not well understood, even though such widespread throughout Europe. this study, beetle taxonomy, conservation value, community composition compared among plantations four post-disturbance approaches: standing deadwood, lying clear cuts, long-term succession. Diversity differed significantly categories, while different families responded similarly. Intact harbored lowest diversity highest taxonomic value was cuts with or deadwood. The proportion forest specialists in successional forests. summary, categories distinct communities family-, species-, ecological guild levels. Therefore, should consider landscape include types. This enhances heterogeneity thus overall biodiversity but could also mitigate negative impacts disturbances ecosystem services.

Abstract The establishment of pastures and forestry plantations has increased globally to meet growing demands for meat wood products. Pasture plantation expansion often drives deforestation, which causes homogenization biotic communities is a major driver the global extinction crisis. A core question how severity losses varies between plantations, in turn, geographical location management characteristics moderate these impacts. Focusing on herpetofauna (amphibians reptiles) as most endangered vertebrate group, we performed synthesis using 41 scientific articles that reported species richness or abundance relative natural forest 191 case studies among 19 countries. We found severe negative effect pasture less herpetofauna. Within total were more negatively impacted amphibians than reptiles, tropics, when planting exotic tree species, monocultures, large commercial clearing understory vegetation. Yet mixed, old, small conservation those permitting recovery vegetation had no impacts reference forest. Synthesis applications . loss underscores importance halting ongoing tropical deforestation intensive plantations. potential appropriately managed support biodiversity regions lacking cover, including via replacement anthropogenic pastures, suggests such have an important role under reforestation agendas.

Abstract Anthropogenic climate and land use change pose threats to biodiversity. For example, timber production is altering forest ecosystems worldwide, often resulting in climate‐sensitive monocultures. In central Europe, ongoing has resulted a large‐scale dieback of spruce plantations, raising concerns about the appropriate management such sites. Here, we investigated direct indirect effects on epigeal spider diversity disturbed, spruce‐dominated landscape western Germany. We compared five strategies evaluated impact various environmental variables taxonomic as well community functional composition. Forest directly affected diversity, with lowest values found stands highest salvage‐logged succession Spider abundance was negatively related canopy closure, positively deadwood occurrence on‐site at scale. Community composition differed strongly among regimes, number specialists occurring open species clear cuts. Our results highlight role non‐intervention sites refuges for spiders highly disturbed landscape, while showed overall diversity. Based distinct assemblages our stress importance heterogeneity should therefore be planned rather than stand‐scale. By applying intervention strategies, monocultures may transformed into diverse landscapes beneficial both biodiversity forestry.

The relationship between stand cumulative production at harvesting age and carbon stock for different soil types in forest plantations is critical sustainable management climate change mitigation. This study evaluated stocks Pinus radiata D. Don on granitic metamorphic soils central Chile. We selected 10 established three 1000 m2 stands per plantation to quantify the of total biomass using allometric equations situ assessments floor mineral (up 1 m deep). A strong positive correlation was observed (r2 = 0.767), regardless type. Metamorphic demonstrated a high capacity, particularly deeper layers (40–100 cm), with contributing over 40% stock. Soil bulk density concentration were strongly correlated 0.74), emphasizing role physical properties storage deep horizons. These findings highlight subsoils as reservoirs. Predictive linear models developed from this offer useful simple approach estimating stocks, national neutrality goals management.

Deadwood plays a key role for biodiversity in forests. A significant number of beetles from this group are currently listed as endangered the Red List. In addition to other management recommendations, there have been recent efforts enrich stands with dead wood promote biodiversity. An important parameter forestry enterprises is optimization these interventions. The study investigated abundance, species richness, gamma diversity, conservation value and biomass saproxylic natural forests using window traps. total 89 traps were used beetle monitoring, which 29 placed on lying logs, 30 snags controls forest stand space. 35,011 recorded 564 (61 families). Notably, 20,515 belong (59%) 311 (55%), 62 classified Red-List (20%). 'all beetles', results indicate that α diversity γ (q = 0) remain consistent across various deadwood types, while β showed differences. Significant differences found group, where differed, higher values observed snags. Rarefaction based richness site was estimated 391 species, including 74 Red-Listed species. Comparing sample coverage studied categories all exhibit pronounced preference inhabiting areas featuring logs. Conversely, mainly inhabit snags, being more similar both (weighted average by status) significantly highest whereas space show lowest measured indices. Furthermore, use set poles resulted an underestimation actual 20%–25%. Our support conclusion indispensable feature beech forests, playing promoting high especially among supporting beetles. Consequently, it becomes crucial incorporate percentage standing managed or actively create equivalent environments introducing stumps.
