Abstract The process of evolution and the structures it produces are best understood in light hierarchy theory. biota traditionally is described by either genealogical Linnaean or economic hierarchies communities ecosystems.

Abstract The native savanna ecosystem of the Orinoquia region is habitat 50% wild ungulate species reported for Colombia. Over last 20 years, this high diversity has been strongly threatened by human transformation natural land cover causing connectivity loss habitats. lacks a biological analysis with multi-species approach involving groups that are representative such as ungulates. Understanding spatial distributions suitable areas and main habitats act primary in these landscapes fundamental design conservation strategies. We use an occurrence dataset lowland tapir ( Tapirus terrestris ), white-tailed deer Odocoileus virginianus white-lipped peccary Tayassu pecari ) development species’ potential distribution models, binarization process, morphological pattern analysis. This information was used modeling dispersal corridors connecting core focal using randomized shortest path algorithm quantifying weighted global metrics. Our results suggest integral corridor least-cost routes between landscape on middle basins rivers Meta River.

Biodiversity dynamics in landscapes with fluctuating connectivity

Ecography, Journal Year: 2023, Volume and Issue: 2023(7)

Published: May 12, 2023

Biodiversity can increase in both high‐ and low‐connected landscapes. However, we lack predictions related to biodiversity dynamics when accounting for the temporal heterogeneity connections among habitats of a landscape. Here, study relationship between fluctuations landscape connectivity at local regional scales. We contrast about species richness landscapes with without connectivity. Our results show that (α) ( γ ) together dynamic characterized by periodic connectivity, clarifying empirical findings high low high‐connected also suggest overall number coexisting compared static no Extending metacommunity theory, including thus provide new testable diversity across broad spatiotemporal scales rapidly changing

Colombia is the world’s fourth most biodiverse country for mammal species. This condition evidenced in high number of species reported specific groups, such as tapirs. The considered a hotspot genus Tapirus , reporting three four scientifically valid ( bairdii T. pinchaque and terrestris ). Approximately ~ 49% Colombia’s natural ecosystems have been transformed by human activities, 16% national territory designated protected areas (PAs). In this context, ecological connectivity between PAs essential to improve conservation threatened large mammals tapirs contribute effectiveness management these current scenario global change. We developed models tapir identified critical conserve connections Colombia.

Both local stability and dispersal contribute to metacommunity sensitivity to asynchronous habitat availability

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Abstract The stability of isolated communities depends on the complexity their foodwebs. However, it remains unclear how local interacts with dispersal in multitrophic metacommunities to shape biodiversity patterns. This lack understanding is deeper more realistic frame landscapes that exhibit non-trivial and time-varying structures. Therefore, this study, we aim evaluate influence stabilizing factors versus determining sensitivity metacommunity increasing asynchrony site availability. Additionally, assess role foodweb landscape structure as modulating factors. To accomplish our goals developed a model based random matrices for communities, which are linked by stochastic over explicit dynamic landscapes. We ran numerical simulations computed effect sizes temperature, self-limitation, ability, all pairwise combinations, asynchrony. In experiments explored gradients species richness, connectance, number sites, modularity. Our results showed among availability periods reduced $$\alpha$$ α -diversity increased $$\beta$$ β -diversity. Asynchrony $$\gamma$$ γ at high rates. Both regional determined Local were influential fewer sites lower modularity, well composed complex research offers insights into dynamics landscapes, providing valuable knowledge about interplay between shaping ecological persistence.
