The InBIO Barcoding Initiative (IBI) Orthoptera dataset contains records of 420 specimens
covering all the eleven Orthoptera families occurring in Portugal. Specimens were collected
in continental Portugal from 2005 to 2021 and were morphologically identified to species
level by taxonomists. A total of 119 species were identified corresponding to about 77% of
all the orthopteran species known from continental Portugal
Meta-analysis of livestock effects on tree regeneration in oak agroforestry systems
Publication . Ibne Wadud, Abdullah; Bugalho, Miguel N.; Vaz, Pedro Gonçalves
Livestock grazing occupies over a quarter of terrestrial land and is prevalent to agroforestry ecosystems,
potentially affecting the survival, growth, and density of trees’ early developmental stages, such as seeds,
seedlings, and saplings. To address the effects of livestock on tree recruitment in the face of ongoing debates
about their impacts, we conducted a 33-year meta-analysis in Quercus-dominated agroforestry systems. Our
analysis revealed a consistently negative effect of livestock on oak acorns, seedlings, and saplings. Significantly,
livestock body size influenced oak regeneration, with small-sized livestock, notably sheep and goats, having a
more pronounced negative impact compared to mixed-size systems, mainly involving cattle and sheep. The ef-
fects of small-sized livestock were markedly detrimental on acorn survival and seedling/sapling density,
although no studies eligible for meta-analysis examined large livestock impacts on acorns. Overall, mixed-size
livestock systems, often involving cattle and sheep, lessen the negative effects. Our findings indicate that the
body size and foraging behaviors of livestock should be considered for the ecological sustainability of the tree
component in agroforestry systems. While protective measures have long been integral to well-managed agro-
forestry systems, our results underscore the importance of integrating diverse livestock sizes and applying spe-
cific protective strategies, particularly for acorns and saplings, to further refine these practices. Future research
should expand to underrepresented regions and livestock types to refine global agroforestry management
practices.
