Abstract:

Abstract Despite the presence of mostly endemic species, the most comprehensive data set on the distribution and ecology of small mammals inhabiting Simien Mountains National Park (SMNP) dated from 1927. The study we carried out and report here provides a unique opportunity to assess the possible role of climate change over the last 88 years on the elevational distribution of mammals in the Ethiopian highlands. Between September and November 2015, three of us (EWC, WTS, YM) collected nonvolant small mammals at four sites (2,900, 3,250, 3,600, and 4,000 m a.s.l.) along the western slope of the Simien Mountains using standardized sampling. Over a 4-week period we recorded 13 species, comprising 11 species of rodents and two of shrews, all endemic to the Ethiopian Plateau. We found the greatest species richness at mid-elevations (3,250 m), consistent with a general pattern found on many other mountains worldwide, but less so in Africa. We compared our species distribution results to the 1927 data set and found upward elevational shifts in species’ ranges, highlighting the role and influence of climate change on the small mammal community. SMNP represents an exceptionally valuable core area of endemism and the best protected natural habitat in northern Ethiopia.

Abstract:

The Ethiopian wolf is a social canid endemic to the highlands of Ethiopia. Today perhaps only 500 individuals survive, making it the world's rarest and probably most endangered canid. Its range has already been reduced and it is threatened by further loss of habitat to high-altitude subsistence agriculture and overgrazing by livestock. Today it survives in only six locations, with the largest and probably only genetically viable population being found in the Bale Mountains National Park. The most immediate threats for the survival of Ethiopian wolves are disease, domestic dogs and human persecution. Improved management in Bale and Simien Mountains National Parks and the establishment of a captive-breeding programme are urgently needed to prevent the extinction of this species.

Abstract:

Walia ibex (Capra walie) is an endangered and endemic species restricted to Simien Mountains National Park (SMNP), Ethiopia. Data on activity patterns of walia ibex were collected during October 2009 to November 2011, and the main objective of the research was to determine diurnal activity patterns of walia ibex in Simien Mountains National Park in order to design sound conservation strategies for the species. Scan sampling method was used for data collection on diurnal activity patterns of walia ibex. Diurnal activity patterns in walia ibex were bimodal, in which they were active before and after noon. They rest in shade on rocks and cliffs during the mid-day to protect themselves from hot sun and predators. Activity patterns of walia ibex during the day showed statistically significant differences (F7,18228= 82.09, df=7, p<0.01). Feeding showed significant differences compared to moving, standing, resting, socializing, and other activities (p<0.05). Diurnal activity records in the walia ibex population during the wet and the dry seasons showed that time spent feeding was the highest and vigilance was the lowest. Knowledge of the pattern of this behavior can especially be useful to design conservation planning as successful reproduction in the population may be threatened by anthropogenic disturbances. Thus, information about the diurnal activity patterns of walia ibex is essential for conservation planning of the endemic and endangered walia ibex in its natural habitats.

Abstract:

Walia Ibex Capra walie is an endemic and endangered species residing in Simien Mountains National Park, Ethiopia. It has shifted its range within the Park in the last decade, and in this study our main objective was to provide information on their feeding ecology to inform recovery goals. We used a scan sampling method to collect foraging information during October 2009 to November 2011. Our observations suggest a diverse diet of more than 28 species of grasses, forbs, and shrubs. The most commonly used plants were Festuca sp., Lobelia rhynchopetalum, Helichrysum citrispinum, and Helichrysum horridum. Walia Ibex were active in feeding before and after mid-day, and time spent feeding was the highest compared with other diurnal activities. The percentage of time spent feeding on major plant species did not differ between wet and dry seasons (p> 0.05). Walia Ibex, however, tended to spend more time browsing than grazing. The generalist nature of foraging behaviour in Walia Ibex most likely contributes to complaints from the local people who witness Walia Ibex raiding crops cultivated in and around the Park. Thus, the contribution of crop raiding to the shifts in the species’ range towards higher altitudes at Sebatminch within Simien Mountains National Park emphasizes the need to consider foraging ecology as community-based conservation efforts are developed to support Walia Ibex in the Park.

Abstract:

Walia ibex (Capra walie) is an endangered and endemic species restricted to the Simien Mountains National Park, Ethiopia. Recent expansion of human populations and livestock grazing in the park has prompted concerns that the range and habitats used by walia ibex have changed. We performed observations of walia ibex, conducted pellet counts of walia ibex and livestock, and measured vegetation and classified habitat characteristics at sample points during wet and dry seasons from October 2009 to November 2011. We assessed the effect of habitat characteristics on the presence of pellets of walia ibex, and then used a spatial model to create a predictive map to determine areas of high potential to support walia ibex. Rocky and shrubby habitats were more preferred than herbaceous habitats. Pellet distribution indicated that livestock and walia ibex were not usually found at the same sample point (i.e. 70% of quadrats with walia pellets were without livestock droppings; 73% of quadrats with livestock droppings did not have walia pellets). The best model to describe probability of presence of walia pellets included effects of herb cover (β = 0.047), shrub cover (β = 0.030), distance to cliff (β = –0.001), distance to road (β = 0.001), and altitude (β = 0.004). Walia ibexes have shifted to the eastern, steeper areas of the park, appearing to coincide with the occurrence of more intense, human–related activities in lowlands. Our study shows the complexities of managing areas that support human populations while also serving as a critical habitat for species of conservation concern.

Zootaxa 2038, no. 1 (March 16, 2009): 1–119. http://dx.doi.org/10.11646/zootaxa.2038.1.1.

Abstract:

The hydraenid genera Parhydraena Orchymont, 1937, Decarthrocerus Orchymont, 1948, Protozantaena Perkins, 1997, and Parhydraenopsis nomen novum are comprehensively revised, based on the study and databasing of 13,323 specimens. Decarthrocerus Orchymont is considered a valid genus, not a subgenus of Parhydraena. A new generic name, Parhydraenopsis nomen novum, is provided to replace Pseudhydraena Orchymont, 1947 (a junior homonym of Pseudhydraena Acloque, 1896). The genera are redescribed, and new species are described in Parhydraena (14), Protozantaena (4), Parhydraenopsis (2), and Decarthrocerus (3). Redescriptions are provided for Parhydraena brevipalpis (Régimbart), P. lancicula Perkins & Balfour-Browne, P. seriata Balfour-Browne, Protozantaena labrata Perkins, Parhydraenopsis cooperi (Orchymont), and Decarthrocerus jeanneli Orchymont. Selected morphological features of Pneuminion Perkins, and members of the tribe Hydraenidini, Hydraenida Germain and Parhydraenida Balfour-Browne, are illustrated and compared with those of members of Parhydraenini. Keys to the genera of Parhydraenini and keys to the species of the genera revised herein are given. Male genitalia, representative spermathecae, antennae, and elytra are illustrated. Scanning electron micrographs of external morphological characters are presented. High resolution digital images of the primary types of all species (except the holotypes of three species, which could not be found) are presented (online version in color), and geographical distributions are mapped. The tribe Parhydraenini has both fully aquatic and humicolous adapted species, and shows notable diversity in the lengths of the maxillary palpi and legs, reflecting the microhabitat type. Humicolous species have relatively short maxillary palpi and tarsi, and often have a specialized body form, as in the very differently shaped members of Discozantaena and Decarthrocerus. Parhydraena has both aquatic and humicolous species, the latter being broad-shouldered species with very short maxillary palpi and tarsi. Protozantaena has one aquatic species, the four other species in the genus being collected by sifting litter in humicolous microhabitats. Species of Decarthrocerus have only been collected by sifting litter; many of the specimens are from bamboo forests. As far as is known, members of Parhydraenopsis are fully aquatic, or found in wet streamside mosses. The following new species are described (type locality in South Africa unless otherwise given): Parhydraena ancylis (Western Cape Province, Heuningnes River), P. asperita (Western Cape Province, Knysna, Diepwalle), P. brahma (Mpumalanga Province, Uitsoek), P. brunovacca (Eastern Cape Province, Umtata, Nquadu Mt.), P. divisa (Sudan, Gilo), P. sebastiani (KwaZulu-Natal Province, Cathedral Peak), P. maculicollis (KwaZulu-Natal Province, Polela River, Himeville), P. maureenae (Western Cape Province, W. Wiedouw farm), P. mpumalanga (Mpumalanga Province, Fanie Botha Trail, Maritzbos Hut area, SW Sabie), P. namaqua (Western Cape Province, Van Rhyns Pass), P. ora (Western Cape Province, Cape Town), P. parva (Western Cape Province, George, Saasveld, Kaaimans River), P. semicostata (Mpumalanga Province, Soutpansberg, Entabeni), P. toro (Western Cape Province, Kirstenbosch, Table Mountain), Protozantaena ankaratra (Madagascar, Antananarivo, Ankaratra, Reserve Manjakatompo, M. Arirana, SE drainage River Ambodimangavo), P. grebennikovi (Tanzania, W. Usambara Mts., Lushoto district, Grant’s Lodge, Mkuzu river, 3–4 km upstream of Kifungilo), P. malagasica (Madagascar, Antsiranana, Parc National Montagne d’Ambre), P. palpalis (Madagascar, Antananarivo, Anjozorobe, Ravoandrina, left affluent of River Ampanakamonty), Parhydraenopsis alta (Ethiopia, Wolamo Province, Mt.

Abstract:

Abstract We studied the population dynamics of endangered mountain nyala Tragelaphus buxtoni between 2003-2005 in the Bale Mountains National Park. Line-transect sampling and total count methods were used to gather data on demographics and movement patterns. The population's age-group composition was 58% adults, 25% sub-adults, 9% juveniles, 5% calves and 3% unidentified with a female-male sex ratio of 2:1. Population density was found to be significantly different between the two sub-populations (Dinsho Sanctuary and Gaysay/Adelay). A significant difference was found for age-group composition across the two sub-populations except adult females, sub-adult males and calves. The Dinsho sub-population was an isolated group. Separation and containment of the mountain nyala population could have negatively affected their ability to search for habitat requirements and mates from distant areas. The population varied between 830-908 individuals (95% CI), a reduction of 45% from earlier reports. However, the mean population density increased due to contraction of the species' habitat range. We observed a population decrease of 2%-5% per year over the course of our study. Many of the assessed demographic parameters did not significantly change over the three years. This suggests that the decrease in nyala population was not due to random variations in reproduction. Anthropogenic factors such as competition with livestock for forage, habitat encroachment and poaching by the local people might have been partly responsible for the depleted population in our study areas.

Abstract:

Bale Mountains National Park is one of the protected areas in Ethiopia that holds the largest area of Afroalpine habitat in Africa and the second largest stand of moist tropical forest. Nevertheless, human settlements, overgrazing, and recurrent fire are the main problems in the park. This study aimed to determine the effects of human-induced landscape change in floristic composition and structure in the park. The vegetation data were collected systematically from 96 sample plots laid along 24 line transects in the edge and interior habitats of the six land cover types. Vegetation composition and landscape structural analysis were made using R software version 3.5.2 and FRAGSTATS version 4.2.1, respectively. Patch number was strong and positively affected species richness (r = −0.90, p < 0.05 ), diversity (r = −0.96, p < 0.01 ), and basal area (r = −0.96, p < 0.001 ), whereas mean patch size was strong and negatively influenced species richness (r = 0.95, p < 0.05 ), diversity (r = 0.87, p < 0.05 ), and basal area (r = 0.82, p < 0.05 ). The overall species richness, Shannon diversity index, and Margalef index were significantly higher in the edge habitat; however, the mean basal area of woody species was significantly higher in the interior habitat at p < 0.05 . This study uncovered that the park is floristically rich and diverse, and it provides a variety of ecological and economic benefits to the surrounding community and to the nation at large. However, these benefits are gradually declining due to the high level of anthropogenic activities in the park. Thus, integrated environmental management strategy that blends with sustainable use of natural resources should be implemented to minimize the threats.

Abstract:

Fire is the most frequent disturbance in the Ericaceous Belt ( ca 3000–4300 m.a.s.l.), one of the most important plant communities of tropical African mountains. Through resprouting after fire, Erica establishes a positive fire feedback under certain burning regimes. However, present-day human activity in the Bale Mountains of Ethiopia includes fire and grazing systems that may have a negative impact on the resilience of the ericaceous ecosystem. Current knowledge of Erica –fire relationships is based on studies of modern vegetation, lacking a longer time perspective that can shed light on baseline conditions for the fire feedback. We hypothesize that fire has influenced Erica communities in the Bale Mountains at millennial time-scales. To test this, we (1) identify the fire history of the Bale Mountains through a pollen and charcoal record from Garba Guracha, a lake at 3950 m.a.s.l., and (2) describe the long-term bidirectional feedback between wildfire and Erica, which may control the ecosystem's resilience. Our results support fire occurrence in the area since ca 14 000 years ago, with particularly intense burning during the early Holocene, 10.8–6.0 cal ka BP. We show that a positive feedback between Erica abundance and fire occurrence was in operation throughout the Lateglacial and Holocene, and interpret the Ericaceous Belt of the Ethiopian mountains as a long-term fire resilient ecosystem. We propose that controlled burning should be an integral part of landscape management in the Bale Mountains National Park.
