Abstract: An individual of spotted hyena Crocuta crocuta
was killed by local people in Elba Protected Area, South-East
Egypt in winter of 2024. This record constitutes the rst
record of the species in contemporary Egypt since its
extinction over 5,000 years ago. The possibility of increased
rainfall and grazing practices creating a corridor for hyena
dispersal from neighboring Sudan was investigated. The
record is 500 km north of the known range of the spotted
hyena.

Spotted hyenas, Crocuta crocuta (Erxleben, 1777), are one of
the most abundant carnivores in Africa with a sub-Saharan
distribution between 17°N and 28°S (Hatton et al. 2015;
Holekamp and Dloniak 2010). Spotted hyenas are remark-
ably adaptable, living in a wide range of habitats. Although
they more commonly occur in mixed forest-savanna, they
also occur in deserts and forests. In semi-arid and arid
regions, spotted hyena populations tend to be smaller
(Holekamp and Dloniak 2010). The species has not been
recorded in contemporary Egypt (Anderson 1902; Basuony
et al. 2010; Hoath 2009; Hoogstraal et al. 1954; Osborn and
Helmy 1980), since becoming extinct over 5,000 years ago
(Yeakel et al. 2014). However, Hofer and Mills (1998),
mentioned unconrmed records from Egypt through ques-
tionnaire surveys. The nearest stable population is in Sudan,
with populations in north and south Darfur, north Kurdufan,
and Dinder national park (Elfaig et al. 2016; Mohammed et al.
2019; Wilson 1979, 1980).
In some instances, spotted hyenas are a human subsi-
dized predator that can co-exist or benet from humans,
even experiencing population increases or range expansion
(Gade 2006; Green et al. 2018; Struller et al. 2022). Spotted
hyenas have been reported in unusual areas far from their
known distributional range (Juste and Castroviejo 1992) as
they can travel approximately 27 km in a day (Bothma and
Walker 1999). This study reports the rst documented record
of spotted hyena in contemporary Egypt. We also explore the
possibility that this new record is attributable to climatic
factors, livestock grazing and human activity in the area.
In February 2024, a spotted hyena killed two goats
belonging to local people in Wadi Yahmib over a two-day
period, within Elba Protected Area, 30 km north of the
Sudanese and Egyptian border (Figures 1 and 2). The goat
depredations occurred at night. The local people are master
trackers and familiar with all large mammals of the area.
The hyena was tracked by local people, located, chased, and
intentionally hit by a pickup truck on February 24, 2024. The
body was observed by (SE), photographed, and left for
scavengers to consume.
The spotted hyena was located 5 km from a small human
settlement of just a few families, in a sandy plain inter-
spersed with rocky hills (Figure 1). The settlement sits 180 m
above sea level. The study area (in which the spotted hyena
was observed) consists of an arid climate, with hot, rainless
summers and mild winters. Precipitation falls mostly in the
autumn and winter months, but is not an annual event
(Mahmoud 2010). The mountains bordering the Red Sea
coast trap moisture as the clouds rise and condense, which
results in higher precipitation and occasional ashoods.
The modest levels of seasonal precipitation (annual average
for the years between 1983 and 2022 is 18 mm ±SE 0.155)
transforms these arid plains into temporary meadows which
are intensively utilized by local pastoralists (De Vries et al.
2013; Funk et al. 2015). The monthly mean temperature
varies between 24 and 38 C˚during the summer and 12 and
26 C˚during the winter (as cited in Mahmoud 2010). This
area is considered a continuation of the Sudanese tropical
region and is the most oristically diverse part of Egypt
(Abd El-Ghani and Abdel-khalik 2006). The area is dominated
by Vachellia tortilis,Lycium shawii, and Balanites aegyptiaca

vegetation (Abd El-Ghani and Abdel-khalik 2006; Zahran and
Willis 2009).
We used historic normalized dierence vegetation index
(NVDI) as an index of precipitation and corresponding pas-
toral grazing opportunity. The interannual average of winter
NDVI was estimated for the potential corridor area between
the northern most range of the spotted hyena in Sudan (Bohm
and Höner 2015; Kingdon 2015) and the tropic of cancer in
Egypt (Figure 1). The NDVI values were obtained using the
Google Earth Engine to analyze the Landsat 5 and 7 satellite
imagery (Gorelick et al. 2017). We examined long-term
changes in NDVI values between the years 1984 and 2022.
Analysis of NDVI values in the potential corridor area
reveals uctuations, with multi-year droughts followed by
shorter wetperiods (Figure 3). Precipitation and corre-
sponding NDVI values have been higher during the past

line) in which NDVI values were calculated between 1984 and 2022 (Figure 3).

ve years (20192022) when compared to the previous two
decades (Figure 3). This ve-year period of less severe
environmental conditions in the corridor area could facili-
tate the dispersal of a spotted hyena northwards into the
south-eastern Egypt. For example, precipitation quantity
and corresponding grazing opportunity is believed to shape
movement and population dynamics of ungulates in the area
(Attum et al. 2014). This period of higher NDVI values is
believed to be associated with increased grazing and stock-
ing rate of livestock (Nagy pers. Observation). The increased
grazing potential as indicated by higher NDVI levels is also
believed to have resulted in a change of pastoral grazing
practices, in which locals now prefer to allow their livestock
to graze freely (free-range grazing) instead of keeping them
in a conned area with supplementary food, even trans-
porting camel herds from Nile valley to the area for free
pasture. In addition, the spotted hyena observation occurred
in the winter, which is the season with the least environ-
mental severity. A male leopard (Panthera pardus) was also
killed in 2014 during the winter, after a livestock depreda-
tion. Leopards historically occur in the area and it is believed
that there may be a few Individuals that still reside in the
southeastern mountains of Egypt or disperse from Sudan
during the winter (Soultan et al. 2016).
Spotted hyenas can live entirely on human food waste,
livestock carcasses, and occasional livestock depredation
(Abay et al. 2011; Struller et al. 2022; Yirga et al. 2015). Native
ungulates occur in the area but their numbers are consid-
ered too low to support a population of large predators due
to environmental and human disturbance (Attum et al. 2014;
Nagy et al. 2022). The people of south-east Egypt are mostly
pastoralists that manage free ranging livestock such as
camels Camelus dromedarius, sheep Ovis aries, goats Capra
hircus, and donkeys Equus asinus. In addition, spotted
hyenas could have been attracted by the nearby slaughter-
house in the village of Shalatin (124 km), which has attracted
numerous scavenger species (such as Egyptian vulture
Neophron percnopterus and Lappet faced vulture Torgos
tracheliotos). Spotted hyena populations are often attracted
to slaughterhouses and even small rural clusters of people
can support hyena populations (Gade 2006). The current
political instability and civil war in Sudan could contribute
to increased spotted hyena populations or distribution as
hyenas engage in anthropophagy and will depredate weak-
ened or vulnerable humans, especially during times of
human crisis (Gade 2006).
Humans in the horn of Africa have tolerated spotted
hyenas given their long history of cohabitating and spotted
hyenas providing the ecosystem service of acting as organic
garbage disposers. There is no cultural history of local peo-
ple in south-eastern Egypt existing with spotted hyenas and
any livestock depredation can be nancially devasting to
local people, especially given their lack of alternative income
(Gade 2006). The local people are more tolerant of smaller
scavengers in Elba Protected Area, such as striped hyena,
Hyaena hyaena, and lappet faced vulture that do not attack
livestock (Basuony et al. 2010). If spotted hyenas would
become established, they would become apex predators in
south-eastern Egypt, given the rarity or lack of large pred-
ators (Soultan et al. 2016). However, we believe that human
persecution and human wildlife-conict will prevent spotted
hyenas from becoming established even when environ-
mental conditions and food availability potentially become
permissible (Green et al. 2018). Our record supports the need
of the spotted hyenas IUCN Red List assessment to be
continuously reviewed to account for the species ability
to disperse and expand its range as a result of changing
climatic conditions or unstable political situations.

corridor area between the northern most

The Dorcas Gazelle, Gazella dorcas, has lost 86% of its global historical range, and is regionally categorized as endangered by the IUCN. The factors that caused this decline have never been quantified. In this work, field and remotely sensed data were used to examine the ecological and anthropogenic factors affecting the abundance of Dorcas Gazelle within Wadi El-Gemal Protected Area in the Eastern desert of Egypt, using Generalized Linear Mixed Models (GLMM). The species’ abundance is shaped by anthropogenic activities (number of car trails and proximity to the coastal road) more than ecological factors (vegetation and wetness indices). Dorcas Gazelle is avoiding more humid and greener areas because of human disturbance. Such suitable habitats may be perceived by gazelles as too dangerous, and the animals therefore prefer less suitable but safer habitats that are further away or less frequented by humans. Moreover, an easy to conduct, cheap monitoring tool, the Kilometric Abundance Index (KAI), was devised and implemented for baseline information to be used for future monitoring of Dorcas Gazelle.

Urban spotted hyenas (Crocuta crocuta) in Ethiopia are a prime example of large carnivores coexisting with little to no conflict with people in a human-dominated landscape, providing a valuable waste-removal service. To gain insight in how this urban lifestyle persists across generations, we studied hyena group composition at the city waste dump of Mekelle, a regional capital in northern Ethiopia. We found that hyena cubs and sub-adults foraged with adults in groups of highly variable composition. Young urban hyenas already take part in a fission-fusion dynamic that is also characteristic of hyenas in non-urban environments. They do not seem to learn from only one or few close reference adults. Social network analysis revealed no clusters among these dump-visiting hyenas. The number of counted hyenas is furthermore larger than any hyena clan in non-urban areas. All individuals were more or less equally connected to each other, and each hyena had a few connections, but to different individuals. All cubs and sub-adults were connected to each other, over a maximum of four links. Hyenas shared the abundance of food at the waste dump without overt aggression. A much larger number of urban hyenas shares this waste dump at night than would fit into a single forest fragment, such as those associated with orthodox churches where small groups of hyenas have often been observed to rest at daytime. Hyenas appear to commute from different dens and resting sites located around the city, but we have no information on their behavior and group composition away from the dump. We observed no defense of any part of the dump area by any of the foraging groups. In absence of territorial behavior at this city site, the clan concept does not seem to apply to these urban hyenas. Similar to what has been observed in other urban carnivores, individuals at the waste dump behaved as members of conflict-free foraging groups ostensibly sharing food without aggression. Perhaps this is what most strikingly defines their urbanity.

Large carnivore populations are declining worldwide due to direct and indirect conflicts with humans. Protected areas are critical for conserving large carnivores, but increasing human-wildlife conflict, tourism, and human population growth near these sanctuaries may have negative effects on the carnivores within sanctuary borders. Our goals were to investigate how anthropogenic disturbance along the edge of the Masai Mara National Reserve, Kenya, influences the demography and space-use of two large carnivore species that engage in intense interspecific competition. Here we document, in one disturbed region of the Reserve, a rapid increase in the population size of one large predator, the spotted hyena (Crocuta crocuta), but a striking concurrent decline in numbers of another, the African lion (Panthera leo). Anthropogenic disturbances negatively affected lion populations, and decreasing lion numbers appear to have a positive effect on hyena populations, indicated here by an increase in juvenile survivorship. We also saw an increase in the number of livestock consumed by hyenas. Our results suggest human population growth and indirect effects of human activity along Reserve boundaries may be effecting a trophic cascade inside the Reserve itself. These results indicate both top-down and bottom-up processes are causing a shift in the carnivore community, and a major disruption of guild structure, inside the boundaries of one of the most spectacular protected areas in Africa.

This article focuses on the study of biodiversity' changes in Khor Abuhabil area. The intentions of the article are to study the change in biodiversity, and distinguish its main indicators and causes. Data were collected from primary and secondary sources together with Geographical Information Systems and Remote Sensing to track the changes in biodiversity through different periods. The descriptive and statistical analytical methods; density index, ARC MAP 10 and ERDAS 8.5 are used for the data analysis. The study points out that changes in biodiversity is a wide spread phenomena in Khor Abuhabil area as indicated by 98.4% of the respondents, the analysis of the satellites images and index of density. The forest and grass area decreased from 3708 km² to 819 km² and from 9817 km² to 4578 km² during the period 1972 to 2013 respectively, and concurrently, the cultivated area increased by 40% during the same period, at the expense of biodiversity. The changes in biodiversity represented by change in vegetation cover including the dominance of Calotrpis procera, Maerua crassifolia, Boscia angustifolis, Guiera senegalensis trees and decreased in Acacia senegal, Acacia mellifera and Dalbergia melanoxylon. The study also indicates the decreased and disappearance of palatable grass species like Triumpettaf lavesscens, Ischamum brachyatherum, Eragrostis pilosa and appearances of unpalatable grass species like Triumpetta flavesscens. The study also showed that many wildlife animals like Panther atigris, Crocuta crocuta, Viverra civetta and Gazella dorcas disappeared whereas birds like Bubulcus ibis, Ploceus galbula and Apus apus have become very abundant. The study concluded that the main causes stand behind the phenomena of change in biodiversity represented in frequent drought years 1973, 1984, 1991 and 2003, fluctuation of rainfall, overgrazing and misuse of trees and over hunting (P ≤ 0.001).

An adult male leopard Panthera pardus was killed in Elba Protected Area in south-east Egypt. This record represents the first confirmed observation in Egypt during the past 65 years, and the first confirmed record in this region. We visited the surrounding areas where the leopard was killed and in areas where tracks were observed by local people to follow the animal’s movement and describe the habitat. The external measurements and the morphology are also described and a tissue sample was preserved for genetic analysis.

The position of Egypt – at the cross-roads between the Middle East and Africa – has attracted the attention of naturalists and explorers for many centuries. Yet while there are many studies relating to the ecology and biology of Egyptian vegetation, the first issue of Zahran and Willis’ Vegetation of Egypt (1992) represented the first attempt to draw this diverse information together. In this second edition, this invaluable text is both updated and expanded to include additional topics such as the role of remote sensing in mapping Egypt’s vegetation, and the economic potential of major desert species. Covering each of the four major eco-geographical regions of Egypt – the Western Desert, the Eastern Desert, the Sinai Peninsula, and the Nile Region – the book integrates a wealth of detail and represents an important landmark in the vegetation of arid and Mediterranean-type regions. As such, it will provide an essential reference to advanced students and researchers in plant science, ecology, biogeography, climatology, economic botany and remote sensing.

To many people the whooping call of the spotted hyaena is as much a symbol of the African night as the haunting call of the fish eagle symbolises the day. Yet, this most abundant large carnivore of the African savannas is often maligned and persecuted because of human prejudices based on ignorance. When the spotted hyaena was originally described scientifically, the error made with the identification of the African wild dog was reversed. Whereas the wild dog was originally described as a form of hyaena, the spotted hyaena was first characterised as a new species of dog, Canis crocuta, from a specimen collected in Senegambia by J.C.P. Erxleben in 1777. It was, however, recognised as a form of hyaena when it was renamed Crocuta crocuta by Kaup in 1828. The name Crocuta itself was not originally used as the generic name for a hyaena, because it was first used by Meigen in 1800 for an insect. This use of Crocuta for an insect classification was suppressed in 1962 in favour of the spotted hyaena in accordance with the International Rules on Zoological Nomenclature.
