Moving through the mosaic: identifying critical linkage zones for large herbivores across a multiple‐use African landscape

چکیده

Reduced connectivity across grassland ecosystems can impair their functional heterogeneity and negatively impact large herbivore populations. Maintaining landscape human-dominated rangelands is therefore a key conservation priority. Integrate data on occurrence species richness with analyses of to identify important areas for maintaining or restoring herbivores. The study was conducted mosaic multiple land uses in Laikipia County, Kenya. We used occupancy estimates four [African elephant (Loxodonta africana), reticulated giraffe (Giraffa reticulata), plains zebra (Equus quagga), Grevy’s grevyi)] derived from aerial surveys create resistance surfaces movement single multi-species assemblage, respectively. validated single-species using telemetry data. circuit theory least cost-path model linkage zones the prioritize restoration. Resistance layers approximated movements our focal species. Results models were highly correlated (rp > 0.9), indicating similar spatial patterns between individual larger assemblage. identified critical that may improve permeability large-herbivore movements. Our analysis highlights utility modeling informing management when animal are scarce. results guide decisions, providing valuable information evaluate trade-offs improving safeguarding livelihoods electrified fences rangelands.

The spatial distribution of African savannah herbivores: species associations and habitat occupancy in a landscape context.

Herbivores play an important role in determining the structure and function of tropical savannahs. Here, we (i) outline a framework for how interactions among large mammalian herbivores, carnivores and environmental variation influence herbivore habitat occupancy in tropical savannahs. We then (ii) use a Bayesian hierarchical model to analyse camera trap data to quantify spatial patterns of hab...

How large herbivores subsidize aquatic food webs in African savannas.

Mass migration—the periodic, synchronized movement of large numbers of animals from one place to another— is an important part of the life cycle of many species. Such migrations are variously a means of avoiding climatic stress, escaping food and water scarcity, and satiating predators (thereby reducing individuals’ risk of being eaten). They are among the most spectacular of natural phenomena,...

DNA metabarcoding illuminates dietary niche partitioning by African large herbivores.

Niche partitioning facilitates species coexistence in a world of limited resources, thereby enriching biodiversity. For decades, biologists have sought to understand how diverse assemblages of large mammalian herbivores (LMH) partition food resources. Several complementary mechanisms have been identified, including differential consumption of grasses versus nongrasses and spatiotemporal stratif...

Identifying Critical States through the Relevance Index

The identification of critical states is a major task in complex systems, and the availability of measures to detect such conditions is of utmost importance. In general, criticality refers to the existence of two qualitatively different behaviors that the same system can exhibit, depending on the values of some parameters. In this paper, we show that the relevance index may be effectively used ...
