Soil sand content is a driving force in structuring bee communities

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted a carefully designed observational study across three soil sand content categories using Dalea purpurea that attracts a wide range of bee species and grows in different soil types. Soil sand content, not floral resource availability, affected patterns of bee distribution, and contrary to expectations, sandier sites did not host the highest

Ethnobotanical survey of pesticidal plants used in South Uganda : case study of Masaka district [PDF]

open access: yes, 2011
Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers,

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Structural variation drives rhizome innovation and adaptive divergence in sister Medicago species

open access: yesJournal of Integrative Plant Biology, EarlyView.
Chromosome‐scale genome analysis, population resequencing, stress‐responsive transcriptomes and functional assays showed that coding and regulatory structural variants, especially gene duplications and noncoding presence‐absence variants, underlie rhizome formation in alpine Medicago archiducis‐nicolai and contrasting xeric adaptation in its non ...

Preference and In Vitro Digestibility of Leaves of Woody Plants by Sheep in the Northern Sudanian Zone

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT In West Africa, trees and shrubs are important for feeding ruminant livestock during the dry season. This study aimed to determine the in vitro digestibility of organic matter from eight woody species using a gas test with and without the addition of polyethylene glycol (PEG), and evaluate their preference by sheep using a cafeteria test ...
