“…Benfontein were unclear, but may have been related to periods of fruiting and availability of main prey. Previous research on canids showed that consumption of fruits typically peaked when fruits were most ripe (Chavez-Ramirez and Slack, 1993;Kamler et al, 2002Kamler et al, , 2007Murdoch et al, 2009). In southern Africa, D. lycioides starts fruiting in mid-summer and peaks in autumn (Mujuru, 2011), at which time ripe berries commonly fall on the ground.…”

“…For example, coyotes (Canis latrans) were found to be the most highly frugivorous north temperate mammal, and this species is likely to be among the quantitatively most important mammalian dispersers of fruit plants in North America (Willson et al, 1993). Similarly, red foxes (Vulpes vulpes) and corsac foxes (V. corsac) were found to be important dispersers of fruit plants in semi-arid parts of southern Europe (Juan et al, 2006;Rosalino and Santos-Reis, 2009;Cancio et al, 2016) and central Asia (Murdoch et al, 2009), respectively.…”

We determined the consumption of fruits and estimated potential seed dispersal of a canid community in semi-arid ecosystems of South Africa by comparing diets, defecation sites, densities and potential seed shadows of cape foxes (Vulpes chama), bat-eared foxes (Otocyon megalotis) and black-backed jackals (Canis mesomelas) on Benfontein and Rooipoort nature reserves. On Benfontein, all canid species consumed the fruit of Diospyros lycioides throughout the year. Jackals, but neither fox species, consumed relatively large amounts of Prosopis spp.(mesquite), an alien invasive. On Rooipoort, jackals had relatively high consumption of Ziziphus mucronata, followed by Grewia flava and D. lycioides. Bat-eared foxes had high consumption of fruit per area, although their seed dispersal potential was low due to their small potential seed shadow and poor germination sites. Cape foxes had the largest potential seed shadow, but their seed dispersal potential was low because of low fruit consumption, low density, and poor germination sites. Jackals had the highest seed dispersal potential because they consumed the most fruit species, had moderate densities, a relatively large potential seed shadow, and mostly

“…Red foxes have been recognized as an important for dispersal and germination of seeds of the Mediterranean hackberry (Juan et al, 2006). Many other studies have highlighted the consumption of plant-based material in red fox diet (Murdoch et al, 2009(Murdoch et al, , D'hondt et al, 2011Díaz-Ruiz et al, 2013;Cancio et al, 2017;Reshamwala et al, 2018). In Pir Lasura National Park in Pakistan, red foxes showed that plants made up 27.54% of the total frequency across 92 scats (Akrim et al, 2019).…”

The red fox (Vulpes vulpes) is a medium-sized carnivore that occurs in different regions of Pakistan, however, still lacks scientific data on its ecology and distribution. The current study investigated the phylogenetic status and diet of the red fox (V.v. griffithii) occurring in Ayubia National Park, Pakistan. Through camera trapping and molecular analysis, we confirmed the occurrence of red fox in the study area. Based on mitochondrial cytochrome B (304 bp) and limited sampling, nearly all red foxes of Ayubia National Park and surrounding Himalayan ranges fall within Holarctic maternal lineage, whereas red foxes found in plains of Pakistan are part of the basal Palearctic maternal lineage. Using 32 scats, we found that red fox diet comprises of 80% animal-based prey species (both wild and domestic) and 19% plant matter. The wild animal prey species included Cape hare (Lepus capensis) and flying squirrel (Pteromyini sp.), which constituted 17% and 15% of diet, respectively. Red foxes infrequently consumed House mouse (Mus musculus), Himalayan Palm civet (Paguma larvata) and sheep (Ovis aries), each comprising around 6% to 9% of red fox diet. The fox species also scavenged on domestic donkey opportunistically. Based on our sampling, our study suggests that the red fox (V.v. griffithii) that occurs in Ayubia National Park and across the lesser Himalayan ranges belongs to Holarctic maternal lineage. The study also highlights consumption of plant seeds by red foxes, indicating it may play an important ecological role in seed dispersal in Ayubia National Park.

“…These fruits are considered as precious remnants of native desert cultures (Rea 1981). Ripe fruits generally remain in the fan palm through the winter (Felger et al 2017), preserved by cold arid conditions (Murdoch et al 2009), offering fruits with highly nutritious mesocarps and endosperms that constitute a critical reward for animal dispersers (Zona & Henderson 1989), consequently, they serve as an important energy source for wildlife through those rough conditions, having fundamental attributes as temporal availability, abundance and nutritional quality.…”

Background: Washingtonia robusta fruits are a staple for birds, small and medium-size mammals, and humans. However, quantitative data of their nutritional contribution has remained unknown. This is the first report on the phytochemical components found in fruit pulp and seeds. Questions: Does pulp compounds favor its consumption and contribute with nutrients for wildlife and humans? Do seed contents favor ecological interactions for germination and plantlet development? Species study: Washingtonia robusta H. Wendl. Study site and dates: Sierra El Aguaje, Sonora, Mexico, February -April 2016 Methods: Chemical and secondary metabolite analyses were carried out from extracts via phytochemical coloring tests and ultra-resolution liquid chromatography. Antioxidant activity was analyzed by DPPH. Results: Washingtonia robusta seeds contain 73 % sugars, 7.4 % protein, 8.4 % humidity, 4.3 % ashes, 8.7 % fat and 0.2 % calcium, while cyanogenic glycosides content was 0.8 μg/g. Pulp has 71 % sugars, 10.8 % protein, 1.6 % humidity, 5.5 % ashes, 9.4 % fat and 1.5 % calcium, and cyanogenic glycosides reached 0.2 μg/g. Alkaloids, tannins, saponins, phenols, and flavonoids were more abundant in seeds than in pulp. The DPPH assay expressed in Trolox equivalents indicated antioxidant capacity. Conclusions: Washingtonia robusta pulp is an important source of sugars and natural antioxidants for wildlife and human consumption. Occurrence of secondary metabolites prevents pathogens in seeds, also they could be beneficial for germination and initial plantlet development. ResumenAntecedentes: Los frutos de Washingtonia robusta son un alimento para aves, pequeños y medianos mamíferos y humanos. Sin embargo, se desconocen los datos cuantificados de su contribución nutricional. Este es el primer informe sobre sus componentes fitoquímicos en la pulpa de su fruta y semillas. Preguntas: ¿Los compuestos de la pulpa favorecen su consumo y contribuyen con nutrientes para la vida silvestre, así como para el consumo humano? ¿El contenido de las semillas favorece las interacciones ecológicas para la germinación y el desarrollo vegetal? Especie en estudio: Washingtonia robusta H. Wendl. Sitio de estudio y fechas: Sierra El Aguaje, Sonora, México, febrero-abril 2016 Métodos: Análisis químico proximal y de metabolitos secundarios a partir de extractos crudos, pruebas fitoquímicas de coloración y cromatografía líquida de ultra resolución; actividad antioxidante por DPPH. Resultados: La semilla contiene 73 % azúcares, 7.4 % proteína, 8.4 % humedad, 4.3 % cenizas, 8.7 % grasa, 0.2 % calcio y glucósidos cianogénicos 0.8 μg/g. Los componentes de la pulpa incluyen: 71 % azúcares, 10.8 % proteína, 1.6 % humedad, 5.5 % cenizas, 9.4 % grasa, 1.5 % calcio y 0.2 μg/g de glucósidos cianogénicos. Los alcaloides, taninos y saponinas son más abundantes en las semillas que en la pulpa, lo mismo ocurre con fenoles y flavonoides. El ensayo DPPH expresado en equivalentes Trolox indicó la capacidad antioxidante. Conclusiones: Los frutos de W. robusta son una fuente de a...
