Research reveals strong community willingness to protect declining wildlife in southern Ethiopia

The investigation, which was carried out through household surveys, focus group discussions, and field observations, revealed that local wildlife populations are under critical strain.

A new study published in the open-access journal BioRisk has highlighted a powerful wave of local support for wildlife conservation in the Hamer District of South Omo, Ethiopia, despite severe environmental pressures.

Researchers from the Ethiopian Biodiversity Institute, the Gullele Botanic Garden, and the University of Szczecin investigated the primary factors driving habitat degradation and evaluated whether communities are prepared to support future conservation strategies.

The investigation, which was carried out through household surveys, focus group discussions, and field observations, revealed that local wildlife populations are under critical strain. An overwhelming majority of the surveyed residents, precisely 82.3 per cent, reported a noticeable decline in wild animal numbers within their vicinity.

Participants identified deforestation and overgrazing as the most significant hazards to local biodiversity, with 63.5 per cent selecting forest clearing as the primary threat and 50.0 per cent identifying livestock overgrazing as the secondary threat. These human-induced activities are exacerbated by recurrent droughts and changing climate patterns, forcing pastoralist communities to venture deeper into natural habitats to seek fodder and water for their livestock.

Despite facing these daily challenges for survival, the local community demonstrated a remarkable commitment to environmental stewardship. The researchers found that 90.6 per cent of the respondents expressed an explicit willingness to participate actively in future wildlife conservation initiatives.

Further, 96.9 per cent of those interviewed acknowledged that the responsibility to safeguard local species rests directly with the community itself, while 99 per cent stated that intervention programmes are an urgent necessity. Statistical modelling demonstrated that factors such as the specific locality, gender, marital status, and length of residence significantly influence an individual’s openness to conservation efforts.

The study notes that local inhabitants traditionally interact with wildlife for various purposes, including utilising certain species for food, traditional remedies, or cultural decorations. However, these practices, combined with habitat loss, have pushed several animals to the brink, leaving the local presence of iconic species such as giraffes and ostriches highly uncertain.

To foster sustainable coexistence between humans and wild animals, the authors recommend implementing managed livestock husbandry practices and constructing dedicated water ponds to alleviate resource competition during dry spells.

They also advocate for the promotion of ecotourism, community-led management initiatives, and stricter enforcement of wildlife protection laws to curb illegal hunting and habitat destruction in the region.

A new crab is settling in the Mediterranean: early evidence of establishment of a Lessepsian species in the Ionian Sea

New research reveals the rapid expansion of the portunid crab, Gonioinfradens giardi, highlighting ongoing biological changes in the Mediterranean Sea.

Guest blog post by Francesco Tiralongo

The Mediterranean Sea is undergoing rapid ecological transformations driven by climate change and human-mediated species introductions. Among the most striking processes is the increasing arrival and establishment of non-indigenous species entering through the Suez Canal, a phenomenon known as Lessepsian migration.

A new study published in Acta Ichthyologica et Piscatoria documents the rapid expansion of the Indo-Pacific swimming crab Gonioinfradens giardi in the Ionian Sea, off the coast of Italy. Following the first confirmed Italian record – a single specimen collected at Portopalo di Capo Passero in November 2025 – researchers documented 11 additional individuals between November 2025 and January 2026, providing early evidence that the species has moved beyond sporadic occurrence and may already be establishing stable populations in the region.

Our findings suggest that Gonioinfradens giardi is transitioning from occasional records to a more consistent presence in the central Mediterranean. This raises important questions about its potential ecological role and interactions with native species.

explains Francesco Tiralongo, lead author of the study

To reconstruct the current distribution of the species, the newly collected data integrates recent records with field observations obtained through a collaboration with local fishers utilizing standard artisanal fishing gears.

The haul of a dozen individuals within a two-month period indicates that environmental conditions are becoming more favorable for its persistence. Furthermore, these captures mark the westernmost presence of the species in the Mediterranean Sea to date.

The rapid emergence of this species highlights how dynamic and responsive Mediterranean ecosystems are to ongoing environmental changes. Documenting these early phases of establishment is crucial for understanding future ecological scenarios and supporting informed management decisions.

adds Alberto Felici, co-author of the study

The establishment of non-indigenous crustaceans may have cascading effects on local ecosystems, including competition with native species and potential implications for fisheries. While the long-term impacts of G. giardi remain uncertain, its rapid spread reflects broader changes already underway in Mediterranean marine biodiversity.

This case adds to a growing list of species reshaping Mediterranean ecosystems. Continuous monitoring, including contributions from fishers and citizen scientists, will be essential to track these dynamics and support adaptive management strategies.

Tiralongo adds
A YouTube video by the study’s lead author, Francesco Tiralongo, in which he introduces Gonioinfradens giardi – a species relatively unknown in the Mediterranean – explains its origin, describes how it entered the ecosystem, and outlines its current distribution in Italian waters as well as its potential impacts on ecosystems and fisheries.

The study contributes to the expanding body of evidence that the Mediterranean Sea is becoming a hotspot for biological invasions, emphasizing the need for coordinated research and monitoring efforts at regional and basin-wide scales.
