Variable impacts of land-based climate mitigation on habitat area for vertebrate diversity

Science, Journal Year: 2025, Volume and Issue: 387(6732), P. 420 - 425

Published: Jan. 23, 2025

Pathways to achieving net zero carbon emissions commonly involve deploying reforestation, afforestation, and bioenergy crops across millions of hectares land. It is often assumed that by helping mitigate climate change, these strategies indirectly benefit biodiversity. Here, we modeled the habitat requirements 14,234 vertebrate species show impact on species’ area tends not arise through mitigation, but rather conversion. Across locations, reforestation provide more both land-cover change whereas loss from afforestation cropping typically outweighs mitigation benefits. This work shows how where land-based can be deployed without inadvertently reducing for global

Patch‐scale edge effects do not indicate landscape‐scale fragmentation effects

Conservation Letters, Journal Year: 2023, Volume and Issue: 17(1)

Published: Nov. 9, 2023

Abstract Negative landscape‐scale fragmentation effects are often inferred from negative patch‐scale edge effects. I tested this cross‐scale extrapolation using two evaluations. First, searched for studies that estimated the direction of both a effect and effect. The directions were concordant discordant in 55% 45% cases, respectively. Second, extracted literature sample on individual species. Then, each species which could calculate slope its Species showing nearly equally likely to show or positive effects, likewise results mean efficacy policies related habitat cannot be observed Such require evidence, comparing species' responses landscapes with different levels fragmentation.

Response of Understory Plant Diversity to Edge Effects in Plantation Forests on the Loess Plateau

Forests, Journal Year: 2025, Volume and Issue: 16(1), P. 87 - 87

Published: Jan. 8, 2025

The majority of the world’s forests are located at landscape edges and highly fragmented; plantations on Loess Plateau no exception, experiencing pronounced edge effects. However, effects often overlooked in assessments carbon storage biodiversity, extent impact these remain inadequately understood. objective this study is to reveal how influence biodiversity species composition examine their long-term impacts ecosystem structure function. Furthermore, it aims explore mechanisms underlying plantation systems. Examining essential for guiding forest management practices formulating effective conservation strategies, thereby providing scientific insights support ecological restoration sustainable plantations. In study, we classified 44 sample plots into four groups according distances from compare analyze composition. Additionally, evaluated intensity range stand structure, diversity, storage. Shannon index understory vegetation was used as dependent variable, with canopy cover, distance, density independent variables. We multiple linear regression factors (shrubs, herbs, trees). key findings were follows: (1) Tree height did not exhibit across any distance range, while index, richness, showed within 54 m edge. Diameter breast (DBH), density, cover exhibited 0–83 (2) significance values 0.99 0.51, respectively, showing significant correlation. contrast, had a positive effect (p = 0.03). (3) Notable differences observed between outermost innermost plantation. Climatic conditions exert dominant plants, altering abundance. High appeared moderate microclimate, contributing higher but reducing Our suggest that varying degrees different indicators. Management decisions should be guided by specific silvicultural objectives, whether manager’s goals optimize biomass accumulation, enhance recovery, or achieve balance two goals.

Landscape scale effects of primary productivity on forest bird species occurrence and abundance in Argentina

Landscape Ecology, Journal Year: 2025, Volume and Issue: 40(3)

Published: March 19, 2025

Approaches estimating landscape effects on biodiversity frequently focus a single extent, finding one 'optimal' or use narrow extents. However, species perceive the environment in different ways, select habitat hierarchically, and respond to multiple selection pressures at extents that best predict each pressure. We aimed assess multi-scale relationships between primary productivity occurrences abundances. used approach, called 'scalograms', level of productivity, form Dynamic Habitat Indices (DHIs) abundances 100 Argentinian forest bird species. average DHI values within (3 $$\times$$ 3 101 pixels; 30 m resolution), 11 'scalogram' metrics as environmental inputs occurrence abundance models. Average cumulative 81 pixels (5.9 – 9.2 km2) maximum across were top three predictors (included models for 41% 18% species, respectively). various contributed ~ 1.6 times more predictive power than expected. For abundances, scalogram measures < 2% less model expected, regardless type (cumulative, minimum, variation). occurrences, but not high levels multiple, broad rather extent.

Impact of Land-Use Change on Vascular Epiphytes: A Review

Plants, Journal Year: 2025, Volume and Issue: 14(8), P. 1188 - 1188

Published: April 11, 2025

Human-caused habitat conversion, degradation, and climate change threaten global biodiversity, particularly in tropical forests where vascular epiphytes—non-parasitic plants growing on other plants—may be especially vulnerable. Epiphytes play vital ecological roles, nutrient cycling by providing habitat, but are disproportionately affected land-use changes due to their reliance host trees specific microclimatic conditions. While tree species secondary recover relatively quickly, epiphyte recolonization is slower, humid montane regions, richness may decline up 96% compared primary or old-growth forests. A review of nearly 300 pertinent studies has revealed a geographic bias toward the Neotropics, with limited research from Asia, Africa, temperate regions. The can grouped into four main areas: 1. trade, use conservation, 2. effects change, 3. diversity human-modified habitats, 4. responses disturbance. In agricultural timber plantations, those using exotic like pine eucalyptus, significantly reduced. contrast, most native shade-grown agroforestry systems support higher richness. Traditional polycultures dense canopy cover maintain 88% diversity, while intensive management practices, such as removal coffee cacao cause substantial biodiversity losses. Conservation strategies should prioritize preserving forests, maintaining forest fragments, minimizing land management. Active restoration, including translocation fallen epiphytes planting vegetation nuclei, more effective than passive approaches. Future include long-term monitoring understand dynamics assess broader impacts loss ecosystem functioning.

Ectomycorrhizal fungal community succession and fragmentation across forest edges nearly three decades postharvest

Plants People Planet, Journal Year: 2025, Volume and Issue: unknown

Published: April 14, 2025

Societal Impact Statement Forest management for wood products involves the conversion of primary forests to younger plantations. This has an immediate impact on biota such as ectomycorrhizal fungi, a diverse symbiotic fungal community. Alternatives large clearcuts may be one way mitigate harvesting effects. We tested this premise by examining communities across forest edges in 1‐ha openings at nearly three decades postharvest. found reductions species richness and shifts community composition were still evident, illustrating how recovery was limited open canopies trees. Sustainable ectomycorrhiza require further conservation strategies, particularly green‐tree retention. Summary Ectomycorrhizal fungi (EMF) are sensitive stand‐removing disturbances; EMF communities, especially rarer typical old‐growth stands, take century re‐establish. Proximity mature via small cutovers could accelerate postharvest recovery, thereby supporting sustainable management. Alternatively, impose fragmentation effect, which eventually negatively influence taxa remaining forest. compared both succession patterns 27 years high‐elevation coniferous sampled 90‐m transects nine openings, using long‐read metabarcoding from mycorrhizal root tips, Sanger sequencing epigeous sporocarps assess response. A timber effect tip with differences among assemblages between opening, edge zone, interior habitats. tips declined 27%, average, beginning 10 m edge. While roots consistent plots, fruiting curtailed within zones, alongside some forest‐dependent taxa. Overall, potential benefits apparently constrained environmental factors that delay re‐establishment late‐seral under canopies. The negative reproduction abundance adjacent is relevant when designing retention forestry systems, suggesting medium patches trees reduce stress better sustain array fungi.
